PAGE 1 - PAGE II 灭火器注塑盖模具设计 摘要 本篇论文讲述了对灭火器注塑盖模具的设计。进行对模具现代行业的发展与现状进行分析，而后开始对塑件的结构进行分析确定好采用什么样的模具设计以及分型面的确定。还对其进行材料性能分析。通过零件本身的结构选定合适的材料，再根据其成型工艺选定合适的设备，最后通过零件本身的结构要求进行设计其注射模具。而后通过UG把塑件的型芯型腔以及侧型芯设计出来，完成后再把已经设计好的模架装配进去。再往后设计出一系列的系统和机构，如浇筑、冷却系统，抽芯、顶出机构等。通过UG把模具设计完成后，再导出装配工程图以及零件图进行修改。 关键词：机械设计，模具设计，CAD绘制二维图  Design of Injection Cover for Fire Extinguisher Abstract This paper describes the design of the mold for the injection cover of the fire extinguisher. Carry on to the mold modern industry development and the present situation carries on the analysis, then begins to the plastic part structure carries on the analysis to determine what kind of mold design as well as the parting surface to determine. The material properties are also analyzed. Through the structure of the parts themselves to select the appropriate material, and then according to its molding process to select the appropriate equipment, and finally through the structural requirements of the parts themselves to design its injection mold. Then the core cavity and side core of the plastic parts are designed by UG, and then the designed mold frame is assembled after the completion. Then a series of systems and mechanisms are designed, such as pouring, cooling, core-pulling and ejecting mechanisms. After the die design is completed by UG, the assembly engineering drawing and part drawing are exported for modification. Key Words: Mechanical design, mold design, CAD drawing 2d  目 录 TOC \o 1-3 \h \u 31213 第1章 绪论 1 31272 1.1 模具行业发展的现状 1 2359 1.2 设计任务 1 5436 第2章 塑件的工艺分析 3 19526 2.1 塑料材料分析 3 16839 2.1.1 塑料材料的基本特性 3 19856 2.1.2 塑件材料主要用途 3 28865 2.1.3 成型工艺性分析 3 20796 2.2 塑件结构 3 14485 2.2.1 灭火器盖塑件 4 29535 2.2.2 结构特点分析 5 3827 2.2.3 塑件尺寸精度及表面质量分析 5 15633 第3章 塑件成型工艺设备 6 16917 3.1 注塑成型工艺 6 3875 3.2 注塑机型号确定 8 13594 第4章 注射模具设计 10 30588 4.1 分型面设计 10 16500 4.2 模架的选用 10 28261 4.3 模具主要参数 11 24178 4.3.1 型腔数量 11 9049 4.3.2 最大注射量 11 19822 4.3.3 锁模力 11 32004 4.3.4 注射压力 12 2359
