This mould considering the precision plastic parts, choose one module and four cavities structure. The mold plastic container cover surface between main body and anti-counterfeiting circle as a parting surface, make the products forced demoulding. Annular flow using belt cold cave, demoulding convenience will condensate material and parts out of the mainstream, to ensure that the molten plastic can reach each cavity at the same time feeding port. In order to make the dynamic model and using the model can accurately movement, guide positioning using guide pillar and guide sleeve, ejector mechanism is putting out an emergence mechanism. Considering the position relationship between parts, cooling water channel using circular distribution, so that uniform, rapid cooling. This design using CAD to achieve plastic container cover design of two-dimensional design and molding parts, analysis of stamping forming quality and complete the parting surface design, in the process of product design and mold assembly, assisted with necessary theoretical calculation, combine digital design and theoretical calculation, can shorten the product development cycle, mold design cycle, improve the accuracy of product design and mold design, product quality, reduce the cost of product development, mold design. Through reasonable design, the mold meet the requirements of production and application. Key words: Injection mold; Plastic analysis; Die design; CAD 目 录 第一章 绪 论 1 1.1 前言 1 1.2 对注塑模具 1 1.3 设计的意义目的 2 第二章 塑料容器盖的工艺性设计 3 2.1 塑件工艺性分析 3 2.2 塑件的材料分析 4 2.3 塑件尺寸精度 5 2.4 模具材料的选择 5 2.5 脱模斜度 6 2.6 腔数目的确定 6 2.7 注射机的选择 6 第三章 模具的结构设计 8 3.1 分型面的确定 8 3.1.1分型面的确定
