The plastic mold is an abbreviation for a combined plastic mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding. The utility model mainly comprises a concave mold having a variable cavity formed by a die combination substrate, a die assembly and a die combination card, and a punch combination substrate, a punch assembly, a punch combination card, a cavity cutting component and A punch having a variable core composed of a side cut composite panel. Coordinated changes in the die, die and auxiliary forming systems. It can process series of plastic parts of different shapes and sizes.
   The injection mold is one of the types of plastic molds, including: injection molds, extrusion molds, and suction molds. Produced like an injection mold, the method of injecting plastic material is used to open the mold and then form a product. Injection mold can also be understood as a mold in the middle of the empty and then there are fixed holes in the body, through the small hole into the plastic material, through high temperature heating, molding, open the mold, get the product.
   There are five major systems for plastic molds: gating system, temperature control system, molded part system, exhaust system, guiding system and ejection system. The gating system and the molded part are in direct contact with the plastic and vary with the plastic and the product. It is the most complicated and most varied part of the mold, and requires the highest degree of smoothness and precision.
