Due to the side-hole of the part, core-pulling mechanism agencies had to be added. Taking all kinds of factors into consideration, then selected the most reasonable program among all the available programs at last, ensured that the plastic was ejected and was manufactured automatic. Pro/E was wildly used throughout the process of 3D injection mould design, the basic principle of parting surface design based on Pro/E was also stated in the paper. 【Key words】Injection mold; core-pulling mechanism; parting surface 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc231974546 前言 PAGEREF _Toc231974546 \h 1 HYPERLINK \l _Toc231974547 第一章 概论 PAGEREF _Toc231974547 \h 2 HYPERLINK \l _Toc231974548 1.1模具在工业生产中的地位 PAGEREF _Toc231974548 \h 2 HYPERLINK \l _Toc231974549 1.2 代模具制造中的新技术 PAGEREF _Toc231974549 \h 2 HYPERLINK \l _Toc231974550 1.3 我国的模具工业的现状 PAGEREF _Toc231974550 \h 4 HYPERLINK \l _Toc231974550 1.4 我国的模具行业的发展趋势 5 HYPERLINK \l _Toc231974551 第二章 塑料罩的结构设计 PAGEREF _Toc231974551 \h 6 HYPERLINK \l _Toc231974552 2.1 设计要求 PAGEREF _Toc231974552 \h 6 HYPERLINK \l _Toc231974553 2.2 塑件成型工艺的可行性分析及修改说明 PAGEREF _Toc231974553 \h 6 HYPERLINK \l _Toc231974554 2.2.1 产品精度分析 PAGEREF _Toc231974554 \h 6 HYPERLINK \l _Toc231974555 2.2.2 脱模斜度设计 PAGEREF _Toc231974555 \h 7 HYPERLINK \l _Toc231974556 2.2.3 塑件壁厚分析 PAGEREF _Toc231974556 \h 7 HYPERLINK \l _To
