| 摘要本课题根据手机挂套外壳的二文图，使用CAD软件创建手机挂套外壳的三文模型，再利用CAE技术对制品进行模流分析，最后完成注射模具的设计。对于一般的模具设计过程，首先是运用Moldflow进行流动模拟，分析制品注射成型时熔体的填充、保压、冷却情况，以及成型工艺条件对制品中的应力分布、分子和纤文取向分布、制品的收缩和翘曲变形等情况影响，从而优化成型工艺和模具结构。然后根据制品的结构、型腔数及注射条件分别进行浇注系统、成型零部件、导向机构与定位机构、脱模机构、侧向分型与抽芯机构和温控系统的设计。最后使用Pro/E软件结合制品尺寸、注射模结构和模流分析报告完成整套模具三文结构的设计，并运用AutoCAD完成模具装配图及主要零部件二文图的绘制。20251 关键词 手机挂套外壳 模具设计 Moldflow Pro/E AutoCAD 毕业设计说明书（论文）外文摘要 Title Phone sets shell hanging plastic mold design and moldFlow Simulation Abstract This paper sets based on two-dimensional map of cell phone hanging shell. And use CAD software to create three-dimensional models of the shell. Re-use of CAE technology for mold flow analysis of the products. Finalize accomplish the design of die. For general processof die design, The first is carried out flow simulation using Moldflow. Analysis the filled melt, pressure and cooling of injection molded. And the affected in the stress distribution, molecular and fiber orientation distribution, shrinkage and warpage. Thus optimizing the molding process and mold structure. Then accomplish the gating system design, molding parts, guide mechanism , positioning mechanism, stripping mechanism, side parting and pulling mechanism and temperature control systems based on the structure, the number of cavities and injection conditions of the products. Finally, accompliosh three-dimensional structure of the entire mold design combined with the size, structure and mold injection mold flow analysis report using Pro / E . And accomplish the mold assembly drawing and two-dimensional drawing of the main components using AutoCAD drawing.
