First analysis of the lug drawing of process characteristics, including materials properties, forming characteristics and conditions, structure and technology, and choose the molding equipment. Then it introduces lug injection mold die structure, and points the selection of type, the determination of cavity number and layout, introduced the gating system, molding parts, molmerged steering mechanism, parting institutions, spacer parting institutions and the design of the cooling system. And then choose the standard formwork and mould material, and the injection machine of process parameters related respectively. The work principle of the die is expounded, and the installation process may be the problems summarized, analyzed, and some solutions are given。This paper discusses lifting lugs injection mould with three plate structure, namely gating system in different parts of the material and the parting surface emergence, use a module and two cavity cavity decorate, finally, using the slider parts will be launched。 Keywords:Lug; Some gate; Side parting and core-pulling mechanism; Spacer parting institutions. 目录 前言 1 1.选题的依据及意义 1 2.国内外研究现状及发展趋势 1 第一章 吊耳工艺性分析 5 1.1塑件（吊耳）分析 5 1.2塑件的结构及成型工艺分析 5 1.2.1 结构分析如下 5 1.2.2 成型工艺分析如下 6 1.3 热塑性塑料PC的注射成型过程及工艺参数 6 1.3.1 注射成型过程 6
