1、天津大学机械工程学院摘摘要要注射成型是塑料成型的主要方法之一。用注射成型方法加工的塑料制品，不仅可以成型复杂结构的制品，而且制品黏度高、质量好，注射成型的生产率也高。由于塑料的物理性能、化学性能与其它材料不同，因此注射塑料制品的设计与成型加工以及模具设计亦有它独特的一面。要设计出结构合理、造型优美、经济耐用的塑料制品，不但要考虑塑料本身的特性，而且要考虑到塑料成型的工艺，模具结构，制品使用环境以及制品的经济效益。一副模具从功能上可分为注射、成型、冷却、脱模等部分；从结构上可分为模架、成型、导向、脱模等部分。本文介绍了模具设计的一般原则和注意事项、模具材料及其选择原则、塑料扣件注射模具设计的整个

2、过程。对具体方案进行了分析论证，并详细分析了各个部分的设计过程，其中包括模架的确立、注射机的选择、模具与注射机有关参数的校核、浇注系统的设计计算、成型零件的尺寸和公差计算、冷却系统的设计计算、脱模机构的设计计算等等。最后绘制了模具装配图和零件图。关键词：关键词：POM注射机冷却水道浇注系统斜滑块模具设计天津大学机械工程学院ABSTRACTABSTRACTinjection molding is one of the main methods of the plastics models. this method ofinjecting model of plastic, not only ca

3、n model the complications structure, and product stickydegree is high, quality is good, and the rate of production which injects to model is also high.the physical function, chemistry function of plastics is different from other materials, so thedesign of injecting plastic, process and the molding d

4、esign also has it special one side. if wewant to design plastic of a reasonable structure, beautiful shape, and economic, we shouldconsider the characteristic of plastics not only, but also the craft of plastic, molding structure,economic performance of product, and the using environment of product.

5、a mold can be divided into inject, model, cool off, take off molds etc. from the functionpart. it can be divided into a mold and molding, leading to, and take off molds etc. from thestructure part. this text introduced general principle and regulation, materials of mold and itschoice principle, the

6、whole process of fastener molding design. carried on analytical argumentto the concrete project, and analyzed each design process of part in detail, including thechoice of mold and injecting machine, checking parameters of injecting machine, design andcalculation of watering system, the model, cooling system and taking off system etc. drew anassembling picture and pictures of parts of mold finally.key words:key words:POM ; Inject the machine ; drawing water ; Gating system ; angled-lift.Splits； Mould desig天津大学机械工程学院
