Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for a protective cover for an automobile. Background Art

[0002] Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise size. 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 the injection molding machine, and after cooling and solidification, the molded product is obtained. Injection molds are divided into two types according to 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 according to the pouring system: cold runner molds and hot runner molds; according to the loading and unloading method, they can be divided into two types: mobile and fixed;

[0003] At present, when it comes to molding protective covers for automobiles, the injection mold itself does not have a heating function, so the injection molding material needs to be heated additionally, which increases the workload and product processing time. In addition, the current mold is not convenient for ejecting the finished product after molding, which is not conducive to production.
