The quality of the hot work of the Crate Mould(FURNITUREMOULD) has a significant impact on the performance and service life of the mould. In the actual life work, our mould shop requires the improvement of the design and production of various moulds, and there will be problems in the specific operation.

The quenching deformation and cracking of the working parts of the crate mould, and the early fracture of the use process are all related to the hot working process of the tool.

(1) Forging process, which is an important part of the manufacturing process of crate mould parts. For moulds of high alloy tool steels, technical requirements are often imposed on metallographic structures such as material carbide distribution. In addition, the forging temperature range should be strictly controlled, the correct heating specification should be established, the correct forging force method should be used, and the post-forging slow cooling or timely annealing should be carried out.

(2) Preparatory heat treatment. Pre-heat treatment processes such as annealing, normalizing or quenching and tempering should be used according to the materials and requirements of the crate mould working parts to improve the structure, eliminate the structural defects of the forged blank, and improve the processing technology. The high-carbon alloy dies steel can eliminate the reticulated secondary cementite or chain carbide after appropriate preliminary heat treatment, so that the carbide is spheroidized and refined, and the uniformity of carbide distribution is promoted. This is beneficial to ensure the quality of quenching and tempering and improve the life of the mould.

(3) Quenching and tempering. This is a key link in the heat treatment of crate mould. If the superheat occurs during quenching, not only will the workpiece cause greater brittleness, but also cause deformation and cracking during cooling, which seriously affects the life of the mould. Special care should be taken to prevent oxidation and decarburization during die quenching. The heat treatment process specification should be strictly controlled. Vacuum heat treatment can be used if conditions permit. After quenching, it should be tempered in time, and different tempering processes should be adopted according to technical requirements.

(4) Stress relief annealing. The working parts of the crate mould should be subjected to stress relief annealing after roughing, with the purpose of eliminating the internal stress caused by rough, so as to avoid excessive deformation and cracking caused by quenching. For moulds with high precision requirements, it needs to be subjected to stress-relieving and tempering after grinding or electric machining, which is beneficial to stabilize mould precision and improve service life.

Injection moulding of Daily Necessities Mould(FURNITUREMOULD) is a processing method used in mass production of some parts with complex shapes. The specific principle refers to the heated and melted plastic raw materials are pushed by the screw of the injection moulding machine and injected into the mould cavity of the daily necessities mould under high pressure, and the plastic formed products are obtained after cooling and curing.

The daily necessities mould consists of a moving mould and a fixed mould, the moving mould is installed on the moving template of the injection moulding machine, and the fixed mould is installed on the fixed template of the injection moulding machine. During injection moulding, the movable mould and the fixed mould are closed to form a gating system and a mould cavity, and during mould opening, the movable mould and the fixed mould are separated to take out plastic products. Although the structure of daily necessities mould may vary greatly due to the variety and performance of plastics, the shape, and structure of plastic products, and the types of injection machines, the basic structure is the same.

The structure of the daily necessities mould is divided into functions, mainly consisting of a pouring system, a temperature adjusting system, a forming part system, an exhaust system, a guide system, an ejection system and the like. Among them, the gating system and moulding parts are the parts in direct contact with the plastic and change with the plastic and the products. They are the parts in the plastic mould that are complicated and vary greatly and require high processing smoothness and precision. In fact, the daily necessities mould is not difficult, no matter how the product changes, for the daily necessities mould to form this product, its structure is nothing more than the above aspects.

1. When the operation needs to be temporarily stopped, the Household Product Mould(FURNITUREMOULD) should be closed to prevent the cavity and the core from being exposed to prevent accidental damage. The downtime is expected to exceed 24 hours, and the surface of the cavity and core should be sprayed. Rust oil or mould release agents, especially in wet areas and rainy seasons, should be rust-proofed for a short time. The moisture in the air will reduce the surface quality of the cavity and the surface quality of the product will decrease. When the household product mould is used again, the oil on the mould should be removed and wiped clean before use. The cleaned compressed air required by the mirror surface is dried and then dried with hot air, otherwise, it will ooze out during moulding and cause defects in the product.

2. After the temporary shutdown, turn on the machine. After opening the household product mould, check whether the slider limit is moved. If no abnormality is found, the mould can be closed. In short, be careful before starting the machine, not careless.

3. In order to extend the service life of the cooling water channel, when the household product mould is deactivated, the water in the cooling water channel should be immediately removed with compressed air, and a small amount of oil should be put into the mouth of the nozzle, and then compressed air is blown to make all the cooling pipes. There is a layer of anti-rust oil.

4. Carefully check the working status of each control unit during work to prevent abnormalities in the auxiliary system, heating, and maintenance of the control system is especially important for hot runner moulds. At the end of each production cycle, rod heaters, belt heaters, and thermocouples should be measured with the mother-in-law and compared with the technical description of the mould to ensure that the function is intact. At the same time, the control loop may be tested by an ammeter mounted in the loop. The oil in the hydraulic cylinder for core pulling is drained as much as possible, and the nozzle is sealed to prevent the hydraulic oil from leaking out or polluting the surrounding environment during storage and transportation.

5. If you hear any abnormal sounds or other abnormalities in the household product mould during production, you should immediately stop the inspection. The mould maintenance personnel shall conduct a patrol inspection on the normal running moulds in the workshop. When abnormal phenomena are found, they shall be dealt with in time.

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.
