带侧孔瓶盖的注塑模设计 摘要 本设计题目为带侧孔的瓶盖注塑模设计，体现了测抽、薄壁类塑料零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者注塑模设计的基础知识，为设计更复杂的注塑模具做好了铺垫和吸取了更深刻的经验。 本设计运用塑料成型工艺及模具设计的基础知识，首先分析了塑件的成分及性能要求，为选取浇口的类型做好了准备；然后估算了塑件的体积，便于选取注塑机及确定型腔数量；最后分析了塑件的特征，确定模具的设计参数、设计要点及推出装置的选龋然后根据制件的形状用UG8.5对该制件的模具进行设分析，并且对于制件的侧孔进行了测抽的设计，还需要考虑开模和侧抽芯的干扰问题。然后对模架进行选择，对一些相关的参数进行校核。完成模具的整体的设计。 关键词：注塑模，浇口，测抽芯机构 With side hole cap i
