设计简介
摘 要
本次设计是塑料注塑模具设计,注塑成型塑件为支撑块,其中的设计内容有零件的工艺性编制:塑件的工艺性分析、塑件的体积和质量计算及注射机参数的确定;结构设计:分型面选择、型腔数确定、浇口设计、侧向分型抽芯机构设计、推出及复位机构方式确定;型芯、型腔尺寸计算;模具加热和冷却系统计算;模具闭合高度确定;注射机有关参数的校核。
塑件尺寸较小,采用一模两腔,单分型面注射结构,把分型面选择在塑件水平投影最大的截面上,推件装置采用推板,推出平稳可靠,推出时不会在塑件上留下顶出痕迹,并采用斜导柱侧向分型机构。
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 the injection mould of the support block
Abstract
This design is plastic injection mold design, plastic injection mold molding plastics is for supporting piece, The design contents are parts of technology establishment:technology Analysis of part,The computation of volume and quality of part,Injection machine parameter is determined;structural design:the choice of parting surface,the determine of cavity number,the design of the gate and the core-pulling mechanism,calculating the size Cores cavity;the calculation mould heating and cooling system,The mold closed highly determined;Injection machine related parameter examination.
Plastics has the smaller dimension, use a two-cavity, single parting surface injection structure,choose the parting surface in plastic parts on the biggest section level umbriferous, use push structure,running calmly and safely, Launched in plastic parts won't leave ejection trace, due to the plastics side has holes, so we must adopt slanted-guide-pillar core-pulling mechanism.
The design of such a structure can be used to ensure reliable Die work to ensure that the other parts of the tie. Finally has carried on the examination to the mold structure and the injection machine match.
