Injection mold is a technical work and different from other processing technologies. When using injection technology, different materials and injection molding processes should be selected according to different molds. This is the difference of injection mold. There are different regulations on raw materials, characteristics and molds.
1. With the emergence of high-speed forming machinery and equipment, the production of plastic products has accelerated. Because the temperature of the injection mold is usually between 165-300 ° C, the fluidity of some parts is poor, and the injection molding speed is fast, which makes the forming environment temperature of some parts of the mold exceed 350 ° C in a very short time. When the working temperature of the abrasive tool is high, the strength and compressive strength of the die will be reduced, resulting in initial damage or plastic deformation failure of the abrasive tool. In order to ensure the precision and fine deformation of abrasive tools in use, the die steel must have high temperature resistance. In order to reduce the temperature, the die steel must have good heat transfer performance and low linear expansion coefficient.
2. It is extreme to have enough temperature at most working standard working temperatures. Abrasives often bear some large loads, which may lead to brittle fracture. Extrusion working pressure is generally 12-45MPa. Therefore, the grinding wheel has high compressive strength and ductility when the die component is used to avoid sudden brittle fracture during operation.
3. The performance of wear-resistant materials and the subsequent expansion of the main research purposes of plastic products enterprises require the addition of inorganic materials such as glass fiber in plastics to improve the plastic deformation of products. Because the addition of food additives has greatly reduced the fluidity of plastics and caused damage to the abrasive tools, it is stipulated that the abrasive tools have an excellent wear-resistant performance.
4. The addition of anti-corrosion flame retardant will release steam etching during the whole process of forming ABS and similar polyepoxy resin. Sometimes, it will rust on the grindstone and destroy the air flow at the intersection point, which is an excellent corrosion resistance of the predetermined mold steel.
5. The excellent drilling production features processing technology and the subsequent replacement of imported plastic products. The appearance is complex and precise. It is stipulated that the steel for grinding tools has excellent processing quality characteristics of drilling manufacturers, and the cold work hardening is small in the whole process of drilling. In order to prevent the deformation of abrasive tools from harming precision, it is expected that the social production development can manipulate the internal stress within a certain limit.
