Abstract:The project for the wireless mouse battery cover injection mold design, through the structural analysis of parts, combined with product quality requirements, design a complete injection mold. According to the general process of injection mold design, the first part of the injection of wireless mouse battery cover parts of the process analysis, to understand the technical requirements of parts to determine the molding program, the use of a four-cavity molding program to ensure product accuracy and productivity, Four buckle structure, set the slanted ejecting mechanism do side of the core puling mechanism, select ABS as injectio n molding materials, ABS has a good performance, is the use of a very wide range of injectio n molding materials. And then the design of the mold, including the choice of injectio n machine, the design of the pouring system, the design of the cooling system, the design of the side core pul ing mechanism, the design of the stripping mechanism and the selection of the standard mold, and the use of moldflow analysis, Machine clamping force, opening stroke, etc. were checked. Final y, the use of Pro/E, EMX drawing parts map. Through this book shows that the design of the mold to achieve the quality of products and processing technology requirements.
