毕业论文：“手机后盖壳”零件“一模二穴”点浇口注塑模具设计.docVIP

西南科技大学毕业设计 PAGE PAGE 33 摘 要 本文主要介绍了“手机后盖壳”零件“一模二穴”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“手机后盖壳”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“手机后盖壳”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：手机后盖壳 注塑模设计 斜抽芯 三板模 Summary This article mainly introduced “the mobile phone, overcrust” components “two 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 mobile phone 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 “mobile phone, 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.
