摘要：本次设计的课题为无线鼠标电池盖注射模具设计，通过对零件的结构分析，结合产品质量要求，设计出一副完整的注塑模。根据注塑模设计的一般过程，首先对无线鼠标电池盖零件进行成型工艺性分析，了解零件的技术要求以确定成型方案，采用一模四腔的成型方案以保证产品精度和生产效率，零件有四个倒钩结构，设置了斜顶做侧抽芯机构，选择ABS作为注塑成型材料，ABS具有良好的性能，是使用非常广泛的一种注塑成型材料。然后进行模具的设计，包括注射机的选择、浇注系统的设计、冷却系统的设计、侧抽芯机构的设计、脱模机构的设计和标准模架的选择，并运用了moldflow进行分析，再对注射机的锁模力、开模行程等进行了校核。最后运用Pro/E、EMX零件图形进行了绘制。本文所设计的模具能达到产品的质量和加工工艺要求。

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.

Keywords:  battery cover;  Injection  mold;  ABS; slanted  ejecting  mechanism;   EMX
