拉线盘注射工艺分析及模具设计(设计说明书10500字,cad图纸9张)
摘要：注射成型是热塑性塑料成型的主要方法之一，可以一次成型形状复杂的精密塑件。本设计进行了一款拉线盘的注塑模设计，对零件结构进行了工艺分析。确定了分型面、浇注系统等，选择了注射机，计算了成型零部件的尺寸。采用侧浇口。利用直导柱导向，推杆顶料,斜顶杆完成脱模及内抽芯方式并对模具的材料进行了选择。如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核。并用autoCAD绘制了一套模具装配图和零件图。

Design of Cable Set Mold and It's Process Analysis of Injection
Abstract: Injection molding is one of the main molding methods for thermo plastics, and it can once-formed delicate plastic members with sophisticated shape. This paper discussed the design of plastic injection mould of the upper cover of the cable set mold., and the process analysis of the parts' structures.The author determined the parting surfaces and the gating system etc, choosed the injection molding machine，calculated the sizes of the molding parts. Side gate and hydraulic inner action was used, straight pillar and puncher was used for guiding and conveying the materials. The author also choosed the materials of the mould. The structure designed in such way can ensure the reliable running of the mould. Finally, the author checked the match between the mould structure and the injection molding machine. And the author also drew a set of mold assembling chart and parts chart using autoCAD software.
Key words: Process of injection;injection mold;Analysis of process;
