简单外罩注塑模具的设计(机械加工工序卡)(含任务书,开题报告,中期检查表,毕业论文说明书7000字,cad图纸17张)                          
摘 要
该设计较系统的介绍了简单注塑模具的设计过程。同时对塑件的成形工艺及模具成型结构对塑件质量的影响进行了分析。在设计过程中，首先对塑件进行工艺分析，了解塑件的材料、形状、尺寸及精度要求，参考工艺的可行性，选择满足要求的工艺方案。然后我按照设计要求对组成注塑模具的成型零部件、浇注系统、导向机构、脱模结构、侧向分型与抽芯机构、加热与冷却系统、排气系统和其它零部件进行设计。在模具设计过程中较多的考虑了模具结构的调整性、易更换性及模具成本。从控制制件尺寸精度出发，对计算机按键注塑模的各主要尺寸进行了理论计算，以确定各工作零件的尺寸。模具零件设计完毕后，对重要的工作结构和零件进行了校核。校核结束后对模具安装并调试。从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各零件的设计。

Abstract
The molding process of plastic parts, the effect analysis to plastic parts quality caused by molding structure, as well as the casting system design, partial and general design of mold moulding introduced respectively. The critical points of mold for plastic design are introduced, and the adjustable character of molding structure、exchange character as well as the molding costs are all considered farther. Starting from controlling dimensional accuracy, the theoretical calculation to the main dimensions of injection molding are carried out so as to determine the size of different parts, the molding design and the process of parts as well as assembling process and etc of injection molding are stated in details.
Key words: process analysis; plastic parts moulding; casting system; molding structure.
