-手机后盖注塑模学士学位论文

摘 要当今社会，工业进展迅速，产品种类多，更新快，模具技术在生产中的作用越来越大，对高质量模具的需求不断增加。本文设计了一副 Nokia5230 手机后盖的注塑模具。首先用 UG6.0 画出塑件，对塑件进行结构分析，选择合适的注塑机，选用PC/ABS 塑料进行注塑。然后对模具的浇注系统，分型面的选用，脱模机构，冷却系统等的设计，成型零件以及模架和标准件的选用。用 AutoCAD 画出模具的装配图和零件图。关键词：注射模具 ；CAD；Nokia5230 手机后盖 AbstractNowadays, the development of industry is rapid; there are many kind of industrial production, Shape continues to accelerate,so mould technology is more and more important in the role of manufacture,the need of high quality mould is increasing.A set of injection mould of the Nokia5230’s backcover has been designed in this article.First of all,describe the plastic part with UG6.0,choose the appropriate injection moud machine with the analysis of the back cover,then choose the PC/ABS to inject.describe the assembly drawing and part drawing by Auto CAD.. The design process of inject system of the mould are specified in detail in this article.Keyword: injection mould ；CAD ；Nokia5230 backcover of the cellphone目 录摘 要.......................................................................................................................................IAbstract..................................................................................................................................II第 1 章 绪 论......................................................................................................................1第 2 章 塑件的结构与工艺性分析......................................................................................42.1 塑件的概述..............................................................................................................42.2 塑件的结构与工艺性分析.............................................
