Description

Technical Field

[0001] The invention relates to the technical field of nut embedding tooling, in particular to a nut rapid embedding die forming tooling. Background Art

[0002] An injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine, and the molded product is obtained after cooling and solidification. Injection molds are divided into two types according to the molding characteristics: thermosetting plastic molds and thermoplastic plastic molds. According to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. Among them, hot compression molds can be divided into three types according to the overflow method: overflow type, semi-overflow type, and non-overflow type. Injection molds can be divided into two types: cold runner molds and hot runner molds according to the pouring system. They can be divided into two types: mobile and fixed according to the loading and unloading method.
