metal stamping die until the entire blanking hole is filled. Of course, the die form of full edge parallel machine mouth will increase the difficulty of die processing, make the preparation of processing technology more complex, and require higher assembly accuracy of the die. However, if the scheme of die edge form is wrong, when the punching blanking hole is blocked, it will be changed to the full edge form, and the cost of scrapping a large number of die and other parts may be greater. Therefore, for high-speed stamping, the form of die edge should be carefully considered. Of course, in order to reduce the processing difficulty of the full edge hole of the die, the design form of steel ball inlaying can also be used for the punching die as much as possible, whether it is in the form of integral die or die block, so as to facilitate the production and processing of standard parts with full edge for the steel ball of the punching die and facilitate the assembly and commissioning of the die. The concave die adopts the structure of inlaying steel balls, which will also bring convenience in processing technology to the maintenance of the die in the future. Prevention of mold deformation during heat treatment on the premise of ensuring the hardness of the mold, pre cooling, staged cooling and quenching or warm quenching processes shall be adopted as far as possible

as for the metal stamping die, ensure the size of the cold hole. The Countermeasures of injection molding process are to increase the injection pressure. Increase injection speed. Fully ensure metering and increase buffer capacity. Extend the holding time. Increase the resin temperature. Increase the nozzle front diameter. Countermeasures for the design of formed parts ※ reduce the change of wall thickness of formed parts. How to prevent the damage of plastic mold during injection molding? Good casting structure design, the wall thickness of the casting shall be as uniform as possible to avoid hot spots, so as to reduce the thermal fatigue caused by local heat concentration of the mold. The corner of the casting shall have appropriate casting fillet to avoid stress caused by sharp corner on the mold. Reasonable design of plastic mold structure each component in the mold should have enough rigidity and strength to bear the pressure without deformation. The wall thickness of the die shall be sufficient to reduce deformation. The gating system is designed to minimize the impact and erosion on the core. Correctly select the tolerance fit and surface roughness of each component. Maintain mold heat balance. Standardize the heat treatment process. The metallographic structure of the material can be changed by heat treatment

metal stamping mold, usually an injection mold, needs to be reviewed in detail. The mold can only be opened after approval. After opening the injection mold, the mold needs to be tested. The following items are required for injection mold manufacturing: the cooling water in the mold is related to the product size, shape, plasticity, holding time and other factors. The roughness of the two versions of the die cavity shall reach the "mirror level", otherwise the product is difficult to demould, and the product needs too much power to be damaged when it is ejected. The roughness of locating pins, surfaces and other parts is specified by standards. The plastic mold shall be rigid, otherwise, when the mold is kept under pressure, deformation will occur, resulting in "flash" to select a reasonable exhaust position and its control amount. Otherwise, the plastic is not filled and the product is "short of material". The injection molding road shall be reasonably selected to make the materials reach the flow path phase at each place evenly, and there shall be enough storage space to supplement the plastic during the shrinkage process. Moreover, the shrinkage coefficient of each material is different, and the mold has a reasonable shrinkage rate

the runner gate design of metal stamping die is too small to be recalculated and expanded. The cold well is blocked. Remove obstacles. Poor exhaust ventilation design. Reduce mold temperature, water temperature and water. The finished meat is too thin to check the exhaust volume or increase the thickness of the meat. The heat pipe is blocked, check the circuit, temperature and maintenance. If the mold is not cooled properly, confirm the water system and modify it. Causes and Countermeasures of raw materials: poor liquidity of raw materials, confirmation or material change. Incorrect lubrication treatment, correct use of site and quantity. Overspray and reduce use. In addition to insufficient filling, the following points also affect injection molding: plastic materials flow out of the joint surface of static and dynamic molds to form burrs, which are called burrs. Shrinkage: this phenomenon is often found in the forming parts list. The main reason is that the raw materials in processing are rolled to the center of the meat, resulting in the depression on the surface of the finished product. In particular, the surface of the meat is particularly large, and the surface is more obvious. Runner marking: molten material
