Table mould processing has very strict temperature requirements. Controlling the injection moulding temperature is an important factor that determines whether the injection moulded products can be qualified. In view of the injection moulding temperature, Today, the Table Mould Manufacturer would like to talk with you about the matters needing attention in table mould processing temperature. The following three points have a direct impact on the table mould processing temperature:

1. Nozzle temperature: The nozzle temperature should not be too low, otherwise the nozzle will be blocked due to the early solidification of molten material, or the performance of the product will be affected due to the injection of the early solidification material into the mould cavity.

2. Table mould temperature: Table mould temperature has a great influence on the internal performance and apparent quality of products. The mould temperature depends on the presence or absence of crystallinity of plastic, the size and structure of products, performance requirements, and other technological conditions.

3. Barrel temperature: The temperature to be controlled in the injection moulding process includes barrel temperature, nozzle temperature and mould temperature. The first two temperatures mainly affect the plasticization and flow of plastic, while the second temperature mainly affects the flow and cooling of plastic.

The quality of table mould products is not determined by machines or production personnel. It comes from the first process, that is, the injection moulding design. The injection moulding design of table mould is an important factor that determines the quality of products in the future.

The height of straight zigzag edges of table mould products should not be too small, otherwise it is difficult to form bending moments that meet the requirements, and it is difficult to obtain parts with accurate shapes. When punching plastic parts with zigzag edges, the interval L from the edge of the hole to the base of zigzag radius R should not be too small, so as to avoid deformation of the hole after zigzag forming, and to avoid inward shortening of the plastic parts when bending. Technical positioning holes can be designed, or both ends can be bent together, and the problem of shortening can be solved by adding width.

The waste of energy in the plastic industry is serious. Due to the high cost of electricity, electricity accounts for a considerable proportion of the enterprise's production cost and has become an important factor in the enterprise's serious environmental production efficiency.

With the intensification of market competition, enterprises are taking various energy-saving measures to reduce production costs and improve market competition. They can customize products according to the motor power, motor speed, pump displacement and system pressure of the user's injection moulding machine to meet all specifications of equipment, installation process and common moulding machines. They are convenient and simple, and are welcomed by the general plastic industry. They not only cater to the national energy conservation and emission reduction, but also save energy and reduce consumption, and also bring considerable economic benefits. It is also very important for energy conservation to reduce the number of mould tests for Crate Mould.

What is the effect of the number of mould tests on the crate mould?

1. The design of the crate mould was not fully reviewed by the collective, and the structure of the crate mould was unreasonable, which made the crate mould undergo many improvements after the mould test, thus making the cost of the crate mould exceed the budget.

If it can be fixed after several improvements, it is lucky. There are many cases that are not satisfactory. Even if the crate mould has to be scrapped and rebuilt, the cost cannot be controlled.

There are also some cases where the design of the crate mould is very good, but the processing of the mould is not in place, which increases the number of mould tests for no reason and directly increases the cost of the crate mould. There is no objection to this problem, so many injection mould manufacturers have increased the investment of measuring equipment.

2. The moulding process and the model of the injection moulding machine were not selected during the mould test. Obviously, the crate mould was well done, but the injection moulded products were not ideal, which increased the number of mould tests for no reason and directly increased the cost of the injection mould.

3. The physical properties of plastic are not fully understood, even the shrinkage rate is not accurate. This happens from time to time. Therefore, the physical properties of plastic must be made clear before designing the crate mould, so as to effectively reduce the number of mould tests.

Air Cooler Mould design is based on correct plastic product design. Mould design and manufacture are closely related to plastic processing. The success or failure of plastic processing depends to a large extent on the mould design effect and mould manufacturing quality. The structural elements to be considered in the mould design of air cooler include:

1. parting surface, that is, the contact surface where the female mould and the male mould cooperate with each other when the mould is closed. The selection of its position and form is influenced by the shape and appearance of the product, wall thickness, moulding method, post-processing technology, mould type and structure, demoulding method, moulding machine structure and other factors.

2. Structural parts, i.e. slide block, inclined top, straight top block, etc. of complex mould. The design of structural parts is very critical, which is related to the service life, processing cycle, cost and product quality of the mould. Therefore, the design of complex core structure of the mould requires higher comprehensive ability of the designer and seeks simpler, more durable and more economical design scheme as much as possible.

The plastic parts are small in size, low in precision grade, and require good performance, no crack, bending resistance and mass production.

In addition to high enough strength and toughness, the surface performance of Chair Mould fittings is crucial to the working performance and service life of high precision mould fittings. The improvement of these properties is very limited and uneconomical to rely solely on the improvement and improvement of matrix materials. Surface treatment technology can often achieve twice the result with half the effort, which is why surface treatment technology has developed rapidly. Polishing technology of chair mould is an important part of mould surface engineering and an important post-treatment process in mould manufacturing process.

The mirror chair mould material is not only a chemical composition problem, but also a series of advanced processes such as vacuum degassing, argon protecting ingot casting, vertical continuous casting and rolling, soft forging and the like are required in smelting, so that the mirror die steel has a series of advantages such as less internal defects, fine impurity particle size, high dispersion degree, fine metal grain size, good uniformity and the like, so as to meet the requirements of the die steel polished to the mirror surface. The surface treatment technology of mould fittings is a systematic project to change the surface morphology, chemical composition, tissue structure and stress state of high precision mould fittings through surface coating, surface modification or composite treatment technology to obtain the required surface performance. Nitriding processes include gas nitriding, ion nitriding, liquid nitriding, etc. In each nitriding mode, there are several nitriding technologies that can meet the requirements of different steel grades and different workpieces. From the way of surface treatment, it can be divided into chemical method, physical method, physical-chemical method and mechanical method.

It is worth noting that the polishing of chair mould surface is not only affected by polishing equipment and technology, but also by the mirror surface of chair mould material, which has not been paid enough attention, that is to say, polishing itself is restricted by mould material. Although new treatment technologies aimed at improving the surface performance of precision mould parts are emerging, nitriding, carburizing and hardened film deposition are mainly used in the manufacture of high precision mould parts. The nitriding technology can form a surface with excellent performance, and the nitriding technology is in good coordination with the quenching technology of high-precision mould fitting steel. At the same time, the nitriding temperature is low, no intense cooling is required after nitriding, and the deformation of high-precision mould fitting is extremely small. Therefore, the surface strengthening of high-precision mould fitting is the earlier and most widely used nitriding technology.

Reducing the processing cost of the Chair Mould can effectively improve the economic benefits of the mould factory production and is beneficial to the improvement of the market competitiveness of the mould factory and the products. If the mould factory can reduce all kinds of unnecessary waste, so as to achieve the purpose of reasonable storage and use of materials, reduce costs and improve efficiency, it can not only ensure the reasonable needs of production but also reduce the waste of capital. So, what is the method to reduce the cost of chair mould processing?

1. Strengthen the management, that is to say, more orders should be received, the production tasks should be full, and the production scale should be formed;

2. Improve labour productivity and adopt standard formwork if conditions permit; Another way is to improve the design level and shorten the trial and adjustment time as much as possible.

3. The more complex the structure of the chair mould, the more the functions of the mould, and the higher the degree of automation in the production of the mould, the higher the production cost of the mould correspondingly;

4. The precision and rigidity of the chair mould should be adapted to the requirements of the objective products and the production program. The higher the precision and rigidity requirements of the mould, the higher the production cost of the mould.

5. Material cost accounts for about 25%-30% of the chair mould production cost. Therefore, the plastic mould material should be selected correctly, and the used plastic mould material should be coordinated with the life requirements of the plastic mould. At the same time, various measures should be taken to give full play to the efficiency of the material.

6. Improving the quality of chair moulds is an important topic, which is an important factor restricting the cost and production cycle of plastic moulds.

The Crate Mould is an industrial product that forms materials in a certain way in a specific structural form. It is also a production tool that can batch produce industrial product parts with certain shape and size requirements. Different crate moulds are made up of different parts. It is a technology to realize the shape processing of articles mainly by changing the physical state of the formed materials.

The manufacture of crate mould refers to the processing technology and maintenance of crate mould. Perhaps many people lack understanding of the mould and do not know what the mould is used for. In fact, it is not difficult. We know that any industrial product is manufactured by mould. For example, the mobile phone shell is produced by heating and softening plastic, injecting plastic mould for forming and cooling, and the car shell is stamped out by metal plate through cavity mould. Nowadays, the traditional production method of manually operating machines to process dies and parts is far from meeting the needs of the times for quality and efficiency. The high precision, high consistency and high productivity produced by dies are incomparable to any other processing method. The dies determine the quality, efficiency and new product development capability of products to a great extent.

Every product needs a good design before it can be planned and processed. Of course, most people are most concerned about some actual situations that should be considered during the overall design of the Table Mould. After all, the environment has become the most important product in the table mould processing industry. However, while these actual processes are being processed, what factors should we specifically consider.

In the process of overall processing of table moulds, innovative parts must be selected according to their own actual conditions. Generally speaking, the mechanical processing performance is relatively good. Products that are especially easy to cut can be selected, and varieties of parts with higher precision can be obtained after processing. In this case, the polishing performance is relatively good. It is suggested that when selecting these table moulds, we had better look at their original actual conditions because, from the current situation, the working surfaces of these parts will be different and all need polishing to meet the requirements of a mirror surface.

During the overall processing of the table mould, the structural design of the concave film should also be considered, because these different structural designs will form various outer surfaces, however, these different structural designs can also be divided into various different styles, such as integrated, embedded, locally embedded, large-area embedded and various different splicing modes.

Even the table mould, in the process of overall processing, also involves the cooling system, because the cooling system in the design, to ensure that the number of cooling water holes as much as possible, and the whole aperture as much as possible, in addition, the cooling water channel should not pass through the original embedded place, at the same time, to prevent the phenomenon of water leakage through this way.

Injection Table Mould is a part that gives plastic shape and size during moulding. Although the structure of the table mould may vary greatly due to the variety and performance of plastic, the shape and structure of plastic products and the types of injection machines, the basic structure is the same.

Injection table mould is divided into thermosetting plastic moulds and thermoplastic plastic moulds according to moulding characteristics. According to the moulding process, the mold can be divided into transfer mold, blow mold, casting mould, thermoforming mould, hot pressing mould (compression mould), injection mould, etc. The hot pressing mould can be divided into overflow mould, semi-overflow mould and non-overflow mould in overflow mode, and the injection mould can be divided into cold runner mould and hot runner mould in the gating system. According to the way of loading and unloading can be divided into mobile, fixed two kinds. Table mould is also classified according to different processing techniques. The injection mould injects molten plastic into the cavity of the table mould at a certain speed and pressure. After the plastic is cooled, the mold is opened to take out the molded injection product.

The compression moulding table mould is simply called a compression mould, which directly adds plastic raw materials into an open mould cavity, closes the mold, the plastic becomes a flowing state and fills the mould cavity under the action of heating and pressure, and then hardens and shapes the product through chemical crosslinking or physical cooling.

The compression moulding table mould uses a heated mold to heat and press the plastic sheet into shape, then opens the mold, takes out the moulded product, and puts it into cold water for shaping and cooling. Compression moulding is an important technical process in moulding and processing. It is widely used in industrial production and processing and plays an important role in people's lives. Generally, powder, granule, pellet, sheet or even a blank with a shape similar to that of the product is put into the cavity of a heated table mould, then the mold is closed and pressurized to form and solidify or vulcanize the product, and then the product is obtained by demoulding. This method is especially suitable for forming thermosetting plastics (see thermosetting resin). Disadvantages are long production cycle, low efficiency and poor dimensional accuracy of products.

The manufacture of Dustbin Mould(FURNITUREMOULD) refers to the processing of forming and blank making tools, in addition to shearing mould and dustbin mould. Usually, the dustbin mould consists of an upper mould and a lower mould. The steel plate is placed between the upper die and the lower die to form the material under the action of the press. When the press is opened, the workpiece determined by the shape of the dustbin die will be obtained or the corresponding waste material will be removed.

Basic characteristics:

(1) High machining accuracy requirements

A pair of moulds is generally composed of female mould, male mould and mould base, and some may be multi-piece modules. Therefore, the combination of upper and lower dies, the combination of insert and cavity, and the combination of modules all require high machining accuracy. The dimensional accuracy of precision dies often reaches μ m.

(2) Complex shape and surface

Some product-shaped surfaces are formed by combining various curved surfaces, so the cavity surface of the mould is very complicated. Some curved surfaces must be treated by mathematical calculation.

(3) Small batch size

Mould production is not mass production, in many cases, only one pair is produced.

(4) Many working procedures

Milling, boring, drilling, reaming, tapping and other processes are always used in the manufacturing of the die.

(5) Repeated production

The use of the mould has a long life. When the service life of a pair of moulds exceeds its service life, a new mould must be replaced, so the production of moulds is often repetitive.

(6) Profiling

Sometimes there is neither pattern nor data in the mould production, and copying processing must be carried out according to the actual objects. This requires high imitation precision and no deformation.

(7) Excellent mould materials and high hardness

The main materials of the mould are mostly made of high-quality alloy steel, especially high-life moulds, which are often made of Leroi steel such as Crl2 and CrWMn. This kind of steel has strict requirements from blank forging, processing to heat treatment. Therefore, the compilation of processing technology cannot be ignored even more. Heat treatment deformation is also a problem that needs to be taken seriously in processing.

According to the above-mentioned characteristics, the selection of machine tools should meet the processing requirements as much as possible. For example, the numerical control system has stronger functions, higher precision of machine tools, better rigidity, better thermal stability and profiling functions.

The working conditions of the Air Cooler Mould(FURNITUREMOULD) are different from those of the cold stamping mould. Generally, the air cooler mould must work at 150 C-200 C. Besides being subjected to certain pressure, it must also be subjected to temperature influence. The basic performance requirements of steel for air cooler mould are summarized as follows according to the use conditions and processing methods of air cooler mould:

1. Sufficient surface hardness and wear resistance

The hardness of the plastic mould is usually below 50-60 HRC. The heat-treated air cooler mould should have sufficient surface hardness to ensure sufficient rigidity of the air cooler mould. During the operation of the mould, due to the filling and flowing of plastic, the mould has to bear large compressive stress and friction force, which requires the mould to maintain the stability of shape accuracy and dimensional accuracy and ensure the mould has sufficient service life. The wear resistance of the mould depends on the chemical composition of the steel and the heat treatment hardness, so improving the hardness of the mould is beneficial to improving its wear resistance.

2. Excellent machinability

In addition to EMD processing, most air cooler mould to need certain cutting processing and fitter repair. In order to prolong the service life of cutting tools, improve cutting performance and reduce surface roughness, the hardness of steel used for air cooler mould must be appropriate.

3. Good polishing performance

For high-quality plastic products, the roughness value of the cavity surface is required to be small. For example, the surface roughness value of the injection mould cavity is required to be less than ra 0.1 ~ 0.25, while the optical surface is required to be ra < 0.01 nm. the mould cavity must be polished to reduce the surface roughness value. The steel materials selected for this purpose require fewer impurities, fine and uniform structure, no fibre directionality, and no pitting or orange peel defects during polishing.

4. Good thermal stability

The shape of air cooler mould parts is often complicated and difficult to process after quenching. It should try to choose the ones with good thermal stability. When the air cooler mould is formed and processed after heat treatment, the linear expansion coefficient is small, the heat treatment deformation is small, the dimensional change rate caused by temperature difference is small, the metallographic structure and the mould size are stable, and the processing can be reduced or stopped, thus ensuring the mould size accuracy and surface roughness requirements.

With the development of the plastic industry, the requirements for the complexity and precision of plastic products are getting higher and higher, and higher requirements are also put forward for mould materials. Pre-hardened steel (such as PMS), corrosion-resistant steel (such as PCR) and low-carbon maraging steel (such as 18Ni-250) can be used for manufacturing complex, precise and corrosion-resistant plastic moulds, all of which have better cutting, heat treatment and polishing properties and higher strength.
