Products with high accuracy requirements of molding to meet the functional requirements of products, ask students to use the basic theory, methods and skills of the professional knowledge and related professional, comprehensive use, according to the structure of the product and the combination of product quality requirements, designed in line with the actual production levels, mould structure with advanced, reasonable process, high economic performance, manufacturing process and formulate the main parts, to solve specific problems of material forming process. Master the basic process of the plastic mold design, improve the computer aided design and consulting relevant literature, the basic skills of design data, standards and norms, completed the graduation design calculation and manual tasks. The product is made of plastic molding, the appearance of high surface quality requirements, the shape is not allowed to stay clear traces, students in the process of comprehensive graduation practice, demoulding structure can learn the special parts, this paper meet the graduation design requirements. To solve the die structure design is reasonable, the exhaust is better, as far as possible to achieve the requirements after the molding accuracy requirements, to consider the deformation in the process of forming. Key words: mechanical design; injection mould; CCC cover. 目 录 摘 要 0 1 绪论 1 1.1 引言 1 1.2 设计在学习模具制造中的作用 1 1.3 主要零件结构分析 2 2 结构设计 3 3 材料的选择 5 4 确定塑料成型方式及工艺过程 7 4.1 成型工艺规程 7 5 分析塑件结构工艺性 8 5.1 塑件尺寸精度分析 8 6 初步选择注塑成型设备 9 6.1依据最大注射量初选设备 9 6.1.1计算塑件的体积 9 6.1.2 计算塑件的质量 9 6.1.3计算每次注射进入模具塑料总体积（总质量） 9 6.2依据最大锁模力初选设备 10 7 确定成型工艺参数 11 7.1 温度 11 7.2压力 11 7.3时间（成型周期） 11 8 分型面的确定与浇注系统设计 12 8.1确定型腔数目及分布 12 8.2选择分型面 12 8.3浇注系统的设计 14 8.3.1主流道设计 14 8.3.2分流道的设计 15 (责任编辑：qin) |
