III 基于Pro/E的充电器后壳注塑模具设计摘 要注塑成型是塑料加工中最普遍采用的方法，适用于全部热塑性塑料和部分热固性塑料。随着注塑模具工业的发展，模具型腔形状和模具结构越来越复杂，模具精度要求越来越高，而生产周期要求越来越短，计算机辅助设计（CAD）可以适应这种需求而应用日渐广泛。本设计的主要内容包括基于Pro/E的充电器后壳模具设计，设计说明书包括两个部分。成型零件的设计和运用EMX生成标准模架两个部分。具体设计中，它包括成型零件的设计和运用Pro/E软件创建零件，对零件结构进行了工艺分析，确定了分型面、浇注系统等，选择了注射机，验算了成型零部件的尺寸，采用点浇口，利用直导柱导向，推杆顶料并对模具的材料进行了选择。如此设计出的结构可确保模具工作运用可靠，其次，利用AUTOCAD作模具的二维图，用Pro/E作三维图。最后运用EMX生成标准模架。关键词 充电器，产品设计，模具Based on Pro / E of the charger cover mold designABSTRACTPlastics injection molding is the most commonly used methods, applicable to all parts of thermosetting plastics and thermoplastic plastics. With the injection mold industry, mold cavity shape and mold the structure of more complex, more and more high-precision molds, and increasingly demanding shorter production cycle, computer-aided design (CAD) can be applied to meet this demand increasingly widespread.The main elements of the design including on the basis of Pro / E of the charger cover mold design, design specification includes two parts. Forming part of the design and application of standards to generate moldbase EMX two parts.A design, which includes shaping the design and use of parts Pro / E software to create parts, the structure of parts of the process analysis of the surface, pouring system, chose the injection machine, checking the size of the molding parts, using the side gate, the use of column-oriented direct introduction, putting the top of the mold material and choice of materials. The structure of such a design work to ensure that the use of a reliable tool, and secondly, the use of AUTOCAD for two-dimensional map of the mold, using Pro / E for the three-dimensional map. EMX to generate the final use of the standard mold.KEY WORDS：charger, product design, mold 目 录摘要 ABSTRACT 序言11塑料的选用21.1 塑料材料的选择21.2 ABS塑料21.3 ABS塑料的特性21.4 ABS塑料的成型特性21.5 ABS塑料的工艺参数32 对塑件设计的原则和要求43制件图53.1制件的体积53.2制件的质量63.3选择注塑机64 注塑机有关工艺参数的校核 74.1最大注射量的校核 74.2注射压力的校核74.3锁模力的校核84.4开模行程和顶出装置的校核84.5模具安装尺寸的校核84.5.1 喷嘴尺寸94.5.2 定位圈尺寸94.5.3 螺孔尺寸94.5.4 模具厚度95 基本方案的确定 105.1型腔数目的确定 105.2分型面的选择105.3排气槽的设计105.4浇注系统的设计11 5.4.1对浇注系统的要求115.5主流道的设计115.6主流道尺寸 125.7主流道衬套和定位环125.8分流道的设计135.9浇口的设计135.10冷却井的设计145.11导向定位机构的概述145.12脱模机构的设计14 5.12.1 机构设计15 5.12.2 脱模力的计算155.13复位机构 165.14侧向分型与抽芯机构16 5.14.1 侧向分型机构与抽芯机构的分类16 5.12.2 抽芯距与抽拔力的计算16 5.14.3 斜导柱侧向分型抽芯机构176 成型零件的设计217型腔壁厚及垫板厚度计算227.1 型腔厚度及底厚度的计算227.2 型芯板厚度的
