摘 要 摘 要 本次设计是塑料注塑模具设计，注塑件为带有外螺纹的指示灯罩，其中的设计内容有零件的工艺性编制：塑件的工艺性分析、塑件的体积和质量计算及注射机参数的确定；结构设计：分型面选择、型腔数确定、浇口设计、推出及复位机构方式确定；型芯、型腔尺寸计算；模具加热和冷却系统计算；斜滑块行程和外形设计；注射机有关参数的校核。塑件尺寸较小，采用一模两腔，双分型面注射结构，把第一分型面选择在塑件水平投影最大的截面上，第二分型面选择在下端外螺纹上。斜滑块装置外侧分型，同时完成塑件的推出动作。浇口位置设置在塑件下端，不影响外观。如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核，并用CAD绘制了一套模具装配图和零件图。关键字：注塑成型；结构设计；CAD；ABSTRACTplastic injection molding would be the mould design. Injection molding parts is a lampshade with external thread. Content for the design includes technic compilation for component, technics analysis for injection molding, calculation of volumn and quanlity for injection molding and confirmation for specification for injection molding machine. Structural design includes alternative joint face, cavities confirmation, mould gate design, confirmation for pushout and reset design. Calculation for mold core, impression, size. Calculation for moulding with cooling and heatening.Technology trip and outlook design. Proofread for relative specification of Injection mold machine. Size of mold part would be relatively small, adopting double cavity mould and structure of biparting surface injection, making the first parting surface choose to be above section of horizontal projection of mold part and making the second part surface at external thread. Angled-lift splits part outward, meanwhile, finishing pushout of mold part. Pouring gate woule be set to be underneath mold part ,which does not effect the outlook so that the structure could garauntee operation of the mould. Last but not least, the matching of structure of mould and injection machine would be proofreaded and assembliy drawing and detail drawing for a full
