And the working principle and the method of the design on the key components of the core-pulling mechanism are detailed analyzed. With the calculation of the plastics part, such as quantity and physical volume. Select the machine with reasonable method and adjust all of the parameter. The plastics inject molding will be design and keep with reasonable, economy and comfortable used. Key words: plastics tie-in; injection mould; core-pulling mechanism. 目 录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc295245080 引 言  PAGEREF _Toc295245080 \h 1  HYPERLINK \l _Toc295245081 1.成型工艺规程编制  PAGEREF _Toc295245081 \h 2  HYPERLINK \l _Toc295245082 1.1塑件的工艺性分析  PAGEREF _Toc295245082 \h 2  HYPERLINK \l _Toc295245083 1.1.1塑件原材料分析  PAGEREF _Toc295245083 \h 2  HYPERLINK \l _Toc295245084 1.1.2塑件的结构和尺寸精度表面质量分析  PAGEREF _Toc295245084 \h 3  HYPERLINK \l _Toc295245085 1.2计算制件的体积和质量  PAGEREF _Toc295245085 \h 4  HYPERLINK \l _Toc295245086 1.3塑件注射工艺参数的确定  PAGEREF _Toc295245086 \h 4  HYPERLINK \l _Toc295245087 2.模具结构的设计  PAGEREF _Toc295245087 \h 5  HYPERLINK \l _Toc295245088 2.1分型面的选择  PAGEREF _Toc295245088 \h 5  HYPERLINK \l _Toc295245089 2.2确定型腔的数量与排列方式  PAGEREF _Toc295245089 \h 5  HYPERLINK \l _Toc295245090 2.3浇注系统和浇口套的设计  PAGEREF _Toc295245090 \h 6  HYPERLINK \l _Toc295245091 2.3.1主流道设计  PAGEREF _Toc295245091 \h 6  HYPERLINK \l _Toc295245092 2.3.2主流道衬套的形式  PAGEREF _Toc295245092 \h 7  HYPERLINK \l _Toc295245093 2.3.3分流道的设计  PAGEREF _Toc295245093 \h 8  H
