JIUJIANG UNIVERSITY 毕 业 设 计 题 目 IPhone5s后盖模具设计 英 文 题 目 Design of protective cover of Iphone 5s injection mold 院 系 机械与材料工程学院 专 业 机械设计制造及自动化 姓 名 张振兴 学 号 11113030347 年 级 2011级（机材A1113） 指 导 教 师 林伟明 二零一五年 六月  摘 要 本设计主要是对Iphone5s手机保护后盖的注塑模具设计,手机保护盖具有重量轻、易清洁、耐摩擦、强度高、使用寿命长，美观大方易携带安装，且制作方便、价格低廉等特点广受手机爱好者喜爱。通过对塑件工艺的分析和比较,最终采取了设计一副注塑模的题目。 通过产品的的生产数量和塑料的工艺性能要求来确定塑件所需决定采用注射成形法。此产品设计针对大批量生产，降低成本目的，且设计的模具需要具有较高的注塑效率，浇注系统要可以自动脱模，此外为确保手机外壳美观要求采用点浇口，最后选择使用单分型面注射模与点浇口自动脱模结构。模具的型腔设计采用一模一腔设置，在浇注系统中则采用点浇口成形，同时为保证很好的推出，推出系统采取十六推杆推出机构完成推出动作。并且针对塑件的工艺性能要求，注塑模中需要有温度冷却调节系统，在此次模具设计中也针对此系统进行了简单设计。此次设计参考了大量的文献期刊、手册标准与网上的许多资料建议，因此设计比较完整。型面注射模具?硬聚氯 ABSTRACT The design is mainly for Iphone5s phone protective cover of plastic injection mold design, mobile phone cover with a light weight, easy to clean, abrasion, high strength, long life, beautiful and easy to carry to install, and easy to manufacture, low price and so wide by phone lovers. Through the plastic parts Process analysis and comparison, eventually took an injection mold design problems. By production volume and plastic process performance requirements to determine the plastic parts needed to decide by injection molding. This product is designed for mass production, cost reduction purposes, and the design of the injection mold is required to have higher efficiency, gating system to automatic ejection, in addition to the aesthetic requirements to ensure that the use of mobile phone casing point gate, the final choice of using a single type injection Mould and automatic ejection point gate structure. Mold cavity design using a model of a chamber is provided, the system is used in the casting point gate forming, as well as ensure a good launch, launch systems take sixteen putt Release agencies to complete the introducti
