Abstract
Mold is the integration of mechanical engineering technology, computer applications, automatic control, numerical control technology and other disciplines into a comprehensive discipline. And thermoplastic injection molding plastic molding is the main method of forming the shape can be a complex precision plastic parts. This paper mainly introduces the car left the race to build dual-mirror cavity injection mold design method and process. In this paper, the left rear-view mirror Jockey Injection Mold covered the design of the development of a reasonable structure, including an analysis of the shape of plastic pieces of the size of the development of the overall structure of the mold design, and selected the necessary injection machine models, forming part of Their Parts and Components design, gating system design, Demoulding body design, cooling system design. According to analysis, mapping of the mold assembly map and dynamic map set mode. The main parts of the mold, as well as a CAD drawing. The design of the vehicle rearview mirror cover mold compact structure, reliable working, convenient operation, steady operation, good cooling effect, low labor intensity, production efficiency, production of plastic parts and high precision, low cost of production.
