摘要本课题主要是针对小型电风扇挡尘板的模具设计,通过对塑件进行工艺的分析和比较,最终设计出一副注塑模。该课题从产品结构工艺性，具体模具结构出发，对模具的浇注系统、模具成型部分的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核、都有详细的设计，同时并简单的编制了模具的加工工艺。通过整个设计过程表明该模具能够达到此塑件所要求的加工工艺。根据题目设计的主要任务是小型电风扇挡尘板注塑模具的设计。也就是设计一副注塑模具来生产小型电风扇挡尘板塑件产品，以实现自动化提高产量。针对小型电风扇挡尘板的具体结构，该模具是侧浇口的注射模具。为了方便脱模，采用了四根顶杆均匀的分布在塑件能承受较大推力的地方，方便了脱模，也简化了模具机构，降低了成本。关键字：塑料模具小型电风扇挡尘板推杆侧浇口目录前言··················································1塑料件的三维零件图····································2第一章塑件工艺分析··································31、塑件分析················································32、电风扇挡尘板的物料性能、成型性能与零件结构··············3第二章注塑设备选择··································41、测量塑件的体积··········································42、计算出塑件的质量········································43、选定注射机··············································44、XS-Z-30型注射机的参数···································5第三章分型面位置的确定·······························51、分型面选择原则···········································52、零件图析确定分型面·······································6第四章浇注系统形式和浇口的设计·······················61、浇注系统设计原则·········································62、主流道衬套设计···········································63、分流道设计···············································74、浇口的设计···············································9第五章成型零件的设计与加工工艺·······················101、定模板的设计·············································112、动模板的设计·············································123、型芯的设计···············································124、模架的设计···············································13第六章合模导向机构设计·······························141、导向与定位机构设计·······································14第七章脱模机构设计···································151、脱模机构设计·············································15第八章注塑...
