Abstract

Plastic injection molding can produce a large quantity of high precision and complex cavity shape of the parts. By using 3D software for plastic parts for analysis, selection of forming process parameters, design of the mold two cavities injection mold. According to the average shrinkage calculation molding size. Analysis of the motorcycle lamp structure technological features, introduced the motorcycle lamp injection mold structure and working process of mold, introduced the mold design scheme, working principle, elaborated the molded parts, injection materials structure, ejecting mechanism design features. At the same time introduces the forming part of the manufacturing process.
