灯座注射模设计 【摘要】 毕业设计的设计内容是灯座注射模设计，材料为PC。塑料模具注射成型的最大特点是：成型周期短，能一次成型外形复杂、尺寸精度高的塑料零件；对各种塑料的适应性强；生产效率高，产品质量稳定，易于实现自动化生产。注射成型的过程是把塑料原料放入料筒中经过加热熔融塑化成为黏流态的流体，在螺杆的高压推动下，使熔体通过喷嘴以较高压力注入模具型腔中，经过冷却、凝固阶段，冷却定型后，然后开模分型脱模后得到塑料制品。设计中主要进行的工作首先是对塑料进行工艺性能的分析并画出塑件零件图，在这次的设计中，要用到内侧抽芯，所以要进行内侧抽芯机构（斜推杆和斜导槽）的设计，以及主、分流道的设计、模具型腔的分布并画出它们的零件图，模架的选择和校核，注塑机的选取和校核等，最重要的是对模具结构中型腔、型芯各径向和高度尺寸的计算过程，这些的设计过程要查阅大量的资料，所有的计算和设计完成后，最后要画出模具设计的总装配图和模具的结构零件图。 【关键词】：灯座，注射模具，PC Injection mold bases 【Abstract】 Graduation is the holder of the design content design of injection mold, the material is PC. plastic mold injection molding characteristic is: molding cycle is short, forming a complex shape can be the size of high precision plastic parts; on the adaptability of various plastics; production efficiency, product quality is stable, easy to automate production. Injection molding process is the plastic material into the barrel through the plastics melt into the fluid viscous flow, driven by high pressure in the screw, so that the higher pressure of the melt through the nozzle into the mold cavity, after cooling, solidification stage, the cooling is formed, and then type mold plastic products obtained after stripping. Mainly for the design work is the first analysis of process performance plastics and painted plastic parts parts diagram, in this design, the use to the inner core pulling, so the inner core pulling (oblique putter and the oblique guide groove) design, as well as the main, the design of shunt, the distribution of the mold cavity and draw part of their plans, the selection and verification mold, injection molding machine such as the selection and verification, the most important medium-sized cavities on the mold structure, core size of the radial and height calculations, the design process to access large amounts of data, all the calculation and design is complete, the final mold design to draw the general assembly drawing and die structure Parts.  【Keywords】: lamp holder, injection
