摘 要本次毕业设计的题目是：工作灯前盖的塑件注射模。本次设计主要是通过对塑件的形状、尺寸与其精度的要求来进行注射成型工艺的可行性分析。塑件的成型工艺性主要包括塑件的壁厚，斜度和圆角以与是否有抽芯机构。通过以上的分析来确定模具分型面、型腔数目、浇口形式、位置大小；其中最重要的是确定型芯和型腔的结构，例如是采纳整体式还是镶拼式，以与它们的定位和固紧方式。此外还分析了模具受力，脱模机构的设计，合模导向机构的设计，冷却系统的设计等。最后绘制完整的模具装配总图和主要的模具零件图。关键词：分型面、浇口、型腔，型芯，镶块，脱摸力。AbstractThe graduation design topic is: working light the front coverof plastics injection mould. This design is mainly through to the plastic parts of shape, size and precision of the requirements to the njection molding process of feasibility analysis. Plastic parts forming technology of plastic parts mainly includes the wall thickness, Angle and rounded and whether any core-pulling mechanism. Through the above analysis to determine the parting surface mold cavity, the gate number, form, position size; One of the most important is sure cores and mold structure, such as the is adopt and or set spelling type, as well as their orientation and solid tight way. In addition, it also analyzes the stress die, the design of the demoulding mechanism, molmerged steering mechanism design, the design of the cooling system. Finally draw complete the mold assembly layout and the main mould drawing.Key words: parting line,the gate, slide block, heel block, core-pulling, core-pulling distance, gate.目录绪论 51 塑料制件的分析 71.1 成型塑料件的工艺性分析 71.2 成型塑件的材料分析 92.塑件成型的基本过程 113 注塑设备的选择 123.1 估算塑件体积质量 123.2 注塑机的选择 124.成型零件有关尺寸的计算 145. 浇注系统的设计 185.1 浇口套的选用 185.2 冷料井的设计 195.3 分流道的设计 195.4 分流道的布置 205.5 浇口设...
