Injection mold is a technical work, which is different from other processing technologies. When using injection technology, different materials should be selected according to different molds and different injection molding processes should be used. 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 speed of plastic products has accelerated. As the injection mold temperature is usually between 165-300 ° C, some parts have poor fluidity and fast injection molding speed, 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 decrease, resulting in the initial damage or plastic deformation failure of the abrasive tool. In order to ensure the accuracy and fine deformation of abrasive tools in use, die steel must have high temperature resistance. In order to reduce the temperature, die steel must have good heat transfer performance and low coefficient of linear expansion.
2. the abrasive with sufficient temperature at most standard operating temperatures is very extreme, and it may cause brittle fracture if it often bears some large loads. Extrusion working pressure, generally 12-45mpa. Therefore, when mold parts are used to avoid sudden embrittlement of work, the grinding wheel has high compressive strength and ductility.
3. the performance of wear-resistant materials and the subsequent expansion of the main research uses of plastic products enterprises. Therefore, inorganic materials such as glass fiber should be added to the plastics to improve the plastic deformation of the products. Because the addition of food additives has greatly reduced the liquidity of the plastics and caused damage to the abrasives, it is required that the abrasives have an excellent wear-resistant performance.
4. adding anti-corrosion flame retardant in the whole process of ABS and similar polyepoxy resin formation will release steam etching, sometimes the grindstone rust and destroy the air flow at the intersection, which is the excellent corrosion resistance of the predetermined die steel.
5. the excellent drilling production carries out processing technical characteristics and the subsequent replacement of imported plastic products. The appearance is complex and precise. It is stipulated that the steel for abrasive tools has excellent processing quality characteristics of drilling production enterprises, and the cold work hardening is small in the whole process of drilling. In order to prevent the deformation of abrasive tools from endangering the precision, it is expected that the internal stress in machining can be controlled within a certain limit with the development of social production.
