Plastic injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. plastic injection mold is a processing method used in the mass production of some complex-shaped parts.

Specifically, it refers to the high-pressure injection of the plastic melted by heat into the mold cavity by the injection molding machine, and the molded product is obtained after cooling and solidification. plastic injection mold are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot press molds (compression molds), injection molds, etc. .

Among them, hot press molds can be divided into three types: overflow type, semi-overflow type, and non-overflow type. The plastic injection mold can be divided into two types: cold runner mold and hot runner mold based on the pouring system; Divided into two types: mobile type and fixed type.
