手机壳设计大学生毕业设计（论文）.doc

1 南京工程学院毕业论文继续教育学院 08级模具设计与制造专业题目: 手机外壳设计学生姓名: 黄涛指导老师: 陈阳 2013 年4月 2 摘要本设计提供了注塑模具的设计方法和流程。首先根据塑件材料及工艺特性对零件进行模流分析,然后选择注塑机并确定型腔数目,接着确定成形方案:总体结构设计、分型面设计、浇注系统设计、脱模机构设计、冷却系统设计等。最后进行注塑机工艺参数校核,包括注射量、锁模力、注射压力、模具厚度和注射机闭合高度等方面。该设计方法对其它不同结构产品的注塑模具设计有一定的参考价值。关键词塑料;注塑模;注塑机。 Abstract: This issue introduces mold design introduces the methods and of all, plastic materials and processes according to characteristics of ponents analysis, and then select the number of injection molding machine and to determine the cavity, and then forming the program to determine: the overall structural design, sub-surface design, casting design, mold release mechanism design, cooling system , injection molding machine parameters checked, including the injection volume, clamping force, injection pressure, mold thickness and the injection machine shut height and so design structure of products of other different injection mold design has some reference value. Key words: Plastic Injection Mould;Plastic Injection Mould Machine 。 3 目录摘要......................................................................................................................................................................... 2 一、概述......................................................................................................................................................... 4 (一) 塑料成型模具在加工工业中的地位.................................................................................................. 4 (二) 手机壳的造型结构发展状况........................................................................................................... 4 (三) 模具发展现状................................................................................................................................... 4 (四) 模具发展趋势................................................................................................................................... 5 (五)存在问题和主要差距..........................................................................
