摘 要 本文主要介绍了“充电器后盖壳”零件“一模一穴”点浇口注塑模具设计的过程。包括零件塑料的工艺分析、零件结构分析、模具结构分析及模具设计等内容。 首先利用UG NX软件对“充电器后盖壳”零件进行三维实体造型，为模仁的设计做好准备，并对产品进行结构和尺寸分析。然后将“充电器后盖壳”的3D图转换成2D图，利用AutoCAD进行成品图、缩水图、结构图、排样图以及组立图的绘制，并确定各种设计尺寸、公差。本次设计的难度在于带有斜抽芯机构，以及三板模的结构设计。设计过程中，使用了UGNX4.0与AUTOCAD等CAD软件。 关键词：充电器后盖壳 注塑模设计 斜抽芯 三板模 Summary This article mainly introduced “the battery charger, overcrust” components “a mold base” runner injection mold design process. Including components contents and so on plastic process study, components structure analysis, mold structure analysis and mold design. First software is right “the battery charger after UG the NX the overcrust” the components carry on the three dimensional solid modeling, prepares for the mold kernels design, and carries on the structure and the size analysis to the product. After then “battery charger, overcrust” the 3D chart transforms the 2D chart, carries on the end product chart, the shrinkage chart, the structure drawing, the platoon specimen map as well as the group using AutoCAD sets up the chart the plan, and determines each kind of design size, the common difference. This designs difficulty has pulled out the core organization slanting, as well as sampan molds structural design. Designs in the process, has used CAD softwares and so on UGNX4.0 and AUTOCAD. Keywords: charger back cover Shell Injection Mold Design Angle Core Pulling three formwork 目 录 引言.................................................4 第一章 毕业设计任务..................................6 第二章“充电器后盖壳”的工艺性分析...................7 2.1 “充电器后盖壳”成型工艺过程分析………….…………………………7 2.2 “充电器后盖壳”的质量和体积分析…………………………………… 8 2.3 “充电器后盖壳”的材料成型工艺参数的分析……………………8 第三章“充电器后盖壳”的结构分析......................9 3.1 “充电器后盖壳”的结构分析…………………………………………… 9 3.2“充电器后盖壳”的精度分析………………………………………10 第四章“充电器后盖壳”模具设计方案论证..............11 4.1 型腔布局…………………………………………………………………11 4.2 顶出机构的确定 …………………………………………………………11 4.3 合模导向机构 ……………………………………………………………11 4.4 冷却系统 …………………………………………………………………11 4.5浇注系统 …………………
