The selection of Chair Mould(FURNITUREMOULD) materials is also important because it not only affects the service life of the chair mould but also directly affects the manufacturing cost of the chair mould. Therefore, some principles should be followed in selecting chair mould materials. Let's take a look below.

(1) According to the type of chair mould processing and its working conditions, the selected materials shall meet the use requirements and shall have higher strength, hardness, wear resistance, impact resistance, fatigue resistance, etc.

(2) selecting materials according to stamping materials and batch production of stamping parts; Meet the processing requirements, should have good processing performance, easy cutting processing, good hardenability, heat treatment deformation is small;

(3) To meet the requirements of the economy, various chair mould parts can be roughly divided into working surface parts, plate parts, shaft parts, sleeve parts, etc. in the processing and manufacturing of chair mould according to the similarity of parts structure and processing process. The processing methods mainly include mechanical processing and special processing. The mechanical processing methods mainly include the cutting processing of various metal cutting machines. Using common and numerical control cutting machines to carry out turning, milling, planing, boring, drilling and grinding processing can complete the processing of most die parts, and then matching with fitter operation can realize the processing and manufacturing of the whole set of dies.

(4) With the continuous improvement of the quality requirements of the chair mould processing, the mould materials with special properties such as high strength, high hardness, and high toughness are appearing continuously and the number of complex profiles and holes is increasing. The traditional mechanical processing methods have been unable to meet the requirements of mould processing. Therefore, the process methods of directly using electric energy, heat energy, light energy, chemical energy, electrochemical energy, acoustic energy, and other special processing have been developed rapidly. At present, the special processing methods mainly based on electrical processing have been widely used in modern mould manufacturing, which is an important supplement to the mechanical processing methods.

As the most important moulding equipment for the processing of injection moulding products, Furniture Mould(FURNITUREMOULD) are directly related to the quality of the products. Therefore, improving the quality of furniture mould, maintaining and maintaining them, and extending their service life are important topics for the cost-effectiveness of injection moulding products processing enterprises.

1. Pay attention to the surface maintenance of furniture mould, which directly affects the surface quality of the product, the focus is to prevent corrosion. After the furniture mould has completed the production task, the residual injection moulding should be carefully removed. The residual injection moulding and other deposits in the furniture mould can be removed with copper rods, copper wire, and soapy water, and then air-dried. Disable the cleaning of hard objects such as wire and steel bars to avoid scratching the surface.

2. Under the normal operation of the furniture mould, test the various properties of the furniture mould, and measure the size of the final moulded plastic part. Through this information, the existing state of the furniture mould can be determined, and the cavity, core, and cooling system can be found. As well as the damage of the parting surface, etc., according to the information provided by the plastic parts, the damage state of the furniture mould and the maintenance measures can be judged.

3. It is necessary to carry out key tracking and inspection of several important parts of furniture mould. The function of the ejection and guiding parts is to ensure the opening and closing movement of the furniture mould and the ejection of the plastic parts. If any part is stuck due to damage, the production will be stopped, so it is necessary to check whether the ejector rod, the guide column, etc. are deformed and surfaced frequently. Damage once found, should be replaced in time.

4. The cleaning of the cooling channels is important for production efficiency and product quality. As the production time continues, the cooling channel is easy to deposit scale, rust, sludge, and algae, which makes the cooling passage section smaller, the cooling passage narrows, greatly reduces the heat exchange rate between the coolant and the furniture mould, and increases the production cost of the enterprise. Therefore, the cleaning of the flow channel should be taken seriously.

5. For hot runner moulds, maintenance of the heating and control system helps prevent production failures.

A well-maintained and maintained furniture mould can shorten the assembly and test time of furniture moulds, reduce production failures, stabilize production, ensure product quality, reduce waste loss, and reduce operating costs and fixed assets investment. At the beginning of the production cycle, the company can smoothly produce quality products. Therefore, for injection moulding products processing enterprises, in the current fierce market competition, the maintenance of good moulds can help the enterprise.

In precision injection moulding, the Air Cooler Mould(FURNITUREMOULD) is one of the keys to obtaining precision plastic products that meet the quality requirements. The air cooler mould for precision injection moulding should meet the requirements of product size, precision, and shape. However, even if the accuracy and size of the air cooler mould are the same, the actual size of the moulded plastic product may be inconsistent due to the difference in the amount of shrinkage. Therefore, effective control of the shrinkage of plastic products is very important in precision injection moulding technology.

Whether the air cooler mould is designed properly or not will directly affect the shrinkage of the plastic product. Since the air cooler mould cavity size is determined by the size of the plastic product plus the estimated shrinkage rate, the shrinkage rate is produced by plastic. A range of values recommended by the manufacturer or engineering plastics manual, not only related to the gate form of the air cooler mould, the position and distribution of the gate, but also the crystal orientation (anisotropic) of the engineering plastic, the shape of the plastic product , size, distance to the gate and location. The main factors affecting plastic shrinkage are heat shrinkage, phase change shrinkage, orientation shrinkage, compression shrinkage, and elastic recovery. These factors are related to the moulding conditions or operating conditions of precision injection moulded products. Therefore, the relationship between these influencing factors and injection moulding conditions and their apparent factors must be considered when designing the air cooler mould, such as injection pressure and cavity pressure and filling speed, injection melt temperature and mould temperature, mould structure, and gate. Form and distribution, as well as the cross-sectional area of ??the gate, the thickness of the product, the content of reinforcing filler in the plastic material, the crystallinity and orientation of the plastic material. The influence of the above factors is also different due to different plastic materials, other moulding conditions such as temperature, humidity, continued crystallization, internal stress after moulding, and changes in the injection moulding machine.

Because the injection moulding process is the process of converting plastic from solid (powder or pellet) to liquid (melt) to solid (product). From the pellets to the melt, from the melt to the product, the temperature field, stress field, flow field, and density field are used in the middle. Under the action of these fields, different plastics (thermosetting or thermoplastic, crystallinity) Or non-crystalline, reinforced or non-reinforced, etc.) have different polymer structural morphology and rheological properties. Any factors that affect the above "field" will affect the physical and mechanical properties, size, shape, precision and appearance quality of plastic products.

The Air Cooler Mould(FURNITUREMOULD) uses a hot runner, and the formed product has no water-free material, which does not require post-processing, which completely automates the entire moulding process, saves working time and improves work efficiency.

The pressure loss is small. The hot runner temperature is equal to the temperature of the injection moulding machine nozzle, avoiding surface condensation of the raw material in the runner, and the injection pressure loss is small. Repeated use of spouts can degrade the performance of plastics, while the use of hot runner systems without spouts can reduce the loss of raw materials and thus reduce production costs. The temperature and pressure in the cavity are uniforms, the stress of the plastic part is small, and the density is uniform. Under a small injection pressure, a shorter moulding time, a better product than the general injection moulding system is injected.

For transparent parts, thin parts, large plastic parts or high-demand plastic parts, it can show its advantages, and it can produce larger products with smaller models. The hot nozzles are standardized, serialized, and equipped with a variety of nozzle tips for interchangeability. The unique design and processing of the electric heating ring can achieve uniform heating temperature and long service life. The hot runner system is equipped with a hot runner plate, a thermostat, etc. The design is exquisite, diverse, easy to use, and stable and reliable. The shortcomings of the application of the runner system: the overall mould closing height is increased, and the overall height of the air cooler mould is increased due to the addition of the hot runner plate. Thermal radiation is difficult to control, and the biggest problem with hot runners is the heat loss of the runner, which is a major issue that needs to be solved. There is thermal expansion, and thermal expansion and contraction are issues that we should consider when designing. Air cooler mould manufacturing costs increase, hot runner system standard accessories are expensive, affecting the popularity of hot runner air cooler mould.

In our daily work and study, we often see two concepts: plastic injection Furniture Mould(FURNITUREMOULD) and plastic furniture mould. What is the difference between the two? In fact, the injection mould and the plastic mould are moulds, which have the same place and are different. To find out the difference between them, we must first understand what is an injection moulding furniture mould and what is a plastic furniture mould.

The plastic furniture mould is a combined plastic mould for compression moulding, extrusion moulding, injection moulding, blow moulding and low foaming moulding, which is mainly composed of a female die base, a female die assembly and a female die combined clamping plate. The improved cavity is a punch with a variable core and consists of a punch combination substrate, a punch assembly, a punch combination clamping plate, a cavity cutting assembly and a side cutting combination plate. Coordinated changes of convex, concave and auxiliary moulding systems of dies. Can process a series of plastic parts with different shapes and sizes.

Injection mould for furniture is a tool for producing plastic products. It is also a tool that provides the complete structure and precise size of plastic products. Injection moulding is a processing method for the mass production of some complex shapes. Specifically, plastic melted by heat is injected into a mould cavity by an injection moulding machine under high pressure, and after cooling and curing, a moulded product is obtained. The injection mould consists of two parts: a moving mould and a fixed mould. The movable mould is installed on the movable mould of the injection moulding machine, and the fixed mould is installed on the fixed mould of the injection moulding machine. During injection moulding, the movable mould and the fixed mould are closed to form a casting system and a mould cavity. When the mould is opened, the movable mould and the fixed mould are separated to take out the plastic product. In order to reduce the heavy workload of mould design and manufacturing, most injection moulds use standard mould bases.

In the thin-wall injection moulding of Furniture Mould(FURNITUREMOULD), it is inevitable to encounter the stress problem of injection moulding, because in the process of thin-wall injection moulding, with the changes of process conditions in various stages, various stress polymerization will occur, and stress concentration is the prominent manifestation of product deformation, warping, brittleness, etc.

Different pressure situations need to be solved from corresponding directions:

1. Furniture mould development: The first material needs to select materials with appropriate strength and rigidity, as well as sliders, mandrels, mandrels, etc. according to many factors such as product strength requirements, machine clamping pressure and product production requirements. Reasonable design, uniform surface treatment of furniture mould, reducing uneven resistance of demoulding.

2. Temperature difference: High melting temperature is helpful for the injection process, but the low temperature of furniture mould will cause uneven cooling, so the temperature difference between the two should be allowed to be minimized.

3. Orientation stress: There are many reasons for polymer chain orientation. Therefore, a comprehensive and accurate analysis of the injection moulding process is the basis for solving orientation stress. Generally, the furniture mould temperature for thin-walled products needs to be higher to ensure that the melt does not solidify prematurely before filling the entire cavity. After the gate is solidified, the holding pressure needs to be evacuated, and too long holding time will cause too much pressure on the melt in the cavity. Injection pressure and injection time are also very important.

1. Purpose: To ensure that the equipment can maintain the best performance state and extend the service life to ensure the normal production.

Responsibilities:

1. This standard must be implemented by trained injection moulding technicians and mould managers.

2. The injection moulding foreman is responsible for implementation and inspection and supervision, and is in charge of regular supervision.

Maintenance of Furniture Mould(FURNITUREMOULD) before production

1. The surface oil and rust of the furniture mould must be cleaned up. Check the cooling water hole of the furniture mould for foreign matter. Is there any waterway?

2. It is necessary to check whether the arc in the rubber mould cover of the furniture is damaged or not, and whether there is any foreign matter remaining.

3. Whether the screws and the clamping clips of the fixed template of the furniture mould are tightened.

4. After the furniture mould is installed on the injection machine, the empty mould must be operated first. Observe whether the operation of each part is flexible, whether there is abnormal phenomenon, whether the active part such as the guide post, the ejector pin, the row position is worn, whether the lubrication is good, the ejection stroke, the opening stroke is in place, and whether the parting surface is in conformity when the mould is closed Strictly wait.

Quarterly routine inspections:

Mainly for the cleaning and maintenance of furniture mould that have not been used for more than two months.

1. Open the furniture mould and check the internal anti-rust effect. If there is any abnormality, it must be re-rustproofed. Long-term use of furniture mould to be buttering.

2. Put it back in place and make a note.

Storage of furniture mould

A mould library should be set up, special personnel should be set up, and furniture mould files should be established. If possible, computer management should be carried out on the moulds. The mould library should choose a place with low moisture and ventilation. The temperature should be kept below 70%. If the humidity exceeds 70%, the mould will be easy to rust. The furniture mould should be stored on the shelf, pay attention to anti-corrosion and dustproof.

1. If the cavity is poorly processed, if there are defects such as scratches, micropores, abrasion, roughness, etc., it will inevitably be reflected on the plastic parts, and the gloss of the plastic parts is poor. In this case, the Air Cooler Mould(FURNITUREMOULD) should be carefully machined to make the cavity surface rougher and chrome-polished if necessary.

2. If the surface of the cavity is oily or watery, or if there are too many release agents, the surface of the plastic part will become darker and darker. To do this, remove grease and water stains in a timely manner and use a limited amount of release agent.

3. If the plastic parts are too small, the demoulding is difficult, or the force is too large when demolding, so that the surface gloss of the plastic parts is good. In this case, the draft angle should be increased.

4. If the air cooler mould is depleted, excess air will be left in the air cooler mould, which will also result in reduced gloss. To do this, check and correct the air cooler mould exhaust system.

5. If the cross-sectional area of the gate or runner is too small or abruptly changed, the shear force is too great when the melt flows therein, and the turbulence is dynamic, resulting in poor gloss. To this end, the cross-sectional area of ??the gate and runner should be properly enlarged.

After a long period of development, the Furniture Mould(FURNITUREMOULD) industry is currently in a rising period. At this stage, what kind of development method should the furniture mould company adopt? It has become a problem that major mould companies are actively thinking about. Long-term price wars are gradually accepted by enterprises, and technological competition is gradually emerging.

The domestic furniture mould industry is at the low end of the world furniture mould industry. This situation is related to the low level of technology and ongoing price wars across the industry. In order to develop, the furniture mould industry must continuously increase research and development funds, increase the technological content, and produce products with core competitiveness. Strengthening product research and development efforts can really change the current competition model.

Why is the domestic furniture mould industry always playing a price war? There are many enterprises engaged in the production of furniture mould in China, but the scale is relatively small, basically all of them are small workshop models, and the technical content is very low.

The products produced by the small furniture mould company are basically imitated, resulting in more and more uniform middle and low-grade moulds. Furniture mould companies are facing the problem of overcapacity and inventory backlog.

In order to increase sales, furniture mould companies will lower the price of their products. Several furniture and mould companies have cut prices, which eventually led to the whole industry being in trouble and the profits of enterprises are becoming less and less. When profits continue to shrink, the company has no additional funds for product development.

Long-term price wars within the industry will affect the entire industry. China's furniture mold companies should increase the technical content of their products, from the current price war to the technical competition.

From now on, it is only necessary to seize market share rather than profit, and become a common market to make a profit. It is believed that after the transformation of the competition model, the production level of the enterprise can be greatly improved, effectively combating vicious competition and bringing the furniture mold industry to a higher level.

1. Easy to process and maintain.

Furniture Mould(FURNITUREMOULD) is a very complicated part. During the processing, they often encounter some complicated structures and special shapes. These shapes are difficult to process and difficult to maintain. For these structures, it can be used to reduce the difficulty of processing and maintenance.

2. Easy to shape and mould.

If the product has deeper ribs or other unformed structures, these structures are prone to under moulding, scorching and other defects. It can effectively solve this problem, the gap between the furniture mould inserts can not only facilitate the exhaust of the furniture mould, but also prevent the vacuum adhesion phenomenon when the product is demolded.

3. Improve the strength of furniture mould.

In the cavity or the slider of the cavity part, it is broken or broken in a small area. In order to increase the strength of the furniture mould and improve the life of the furniture mould, the plug can be broken (or broken) and the material can be replaced.

4. Save materials and reduce costs.

When there are cavities or sliders on the furniture mould parts, when other surface parts have many shapes or are used for processing, the furniture mould inserts can be torn to save materials and reduce processing cost, otherwise the material size will increase and the processing time is low. There will be a lot of waste in costs.
