Abstract

Injection molding process has been widely used in China's agricultural、 industrial、 manufacturing、defense and other aspects of daily life. In order to explore the injection molding process and mold production process design and manufacturing process, this graduation design reference books, combined with real life, the production of injection molds for the entire design process detailed inquiry.

This article will bench plastic injection mold design, detailed description of the entire mold design process. The main contents include a basic introduction to plastic parts, design selection and verification, working principle and structure of the mold, pouring system structure and plastic parts molding process analysis, choice of materials and molding process, injection machine, forming part of the design, side parting pulling mechanism design, design-oriented organization designed to mold temperature control system, the design of the exhaust system, the introduction of design institutions. After the characteristics and process characteristics of plastic parts correct analysis of the material, the use of three-dimensional software for plastic parts and mold design, manufacturing and quality analysis; using CAXA software to draw a complete mold assembly drawing and its major parts diagram. The design of the integrated use of multi-professional knowledge, such as mold design and manufacture of basic theory, mechanical design, material forming the basis of the plastic molding process, basic computer technology, tooling CAD / CAM and so on.

Key points through the entire mold design process, and further deepen their understanding of the injection molding process, but also to consolidate the process of forming the type, structure and operating principles of the theory of knowledge, as well as summary and master mold design and in practice.

Keywords: Molding process; design; making; plastic.
