Abstract
Injection mould plastic industry is the fastest growing industrial categories, one of injection mold is one of the types of the fast development, therefore, the study to understand plastic injection mold production process and improve the quality of products has great significance. This paper discusses the application Pro/puter aided design thread cover the design method of the injection mould, this paper introduces the basic principle of injection molding, especially the parting surface of the injection mould structure and work principle. Injection molding is the main method of thermoplastic moulding, one of the design of injection mold design thread cover, the die structure and the matching of the injection machine virwpoint; The process of parts structure analysis; Sure the parting surface, gating system, etc.; Choose the injection machine; A simple calculation of the molding parts size; And draw a set of AUTOCAD mold assembly drawing, introduces the name of each part of assembly drawings, simply explains the working process of the die. So the structure of the design to ensure reliable mould work. Through the design, can have a preliminary injection moulds know, pay attention to the details of the design, knowledge of the mould structure and work principle.
Key words: injection mold; Cavity; Parting surface; Pouring system; Injection machines.
