不同模数塑料玩具齿轮的模具优化设计 摘 要 塑料已成为国民经济生产必不可少的原材料，塑料齿轮在玩具中应用在今天也很常见，采用塑料齿轮的玩具因其质量轻，无毒害，成本低，制造容易而深受人们喜爱，所以本次选取塑料齿轮为设计对象，通过对模数不完全相同的四个塑料齿轮塑件进行分析从而绘制出该塑料齿轮的模具。在本次的模具设计中采取了一模四腔，由于在浇注过程中可能存在浇注不均匀现象，造成成型零件质量问题，故对本模具进行了优化设计来保障浇注过程中尽可能的均匀，保证零件质量，使零件可以大量生产。本次设计过程中，对模具分型面的选择，成型零部件，浇注系统的选择进行了详细介绍。另外，对与顶出系统和冷却系统也进行了适当叙述，保障了此次设计的模具能较好的满足使用要求。 本次设计，采用了Solidworks，Autocad等软件，通过这次的设计，更加熟练巩固使用Solidworks,Autocad设计分析软件，对模具设计加深了认知，体验到设计人员的艰辛与不宜。 关键词：注塑模设计；浇注系统；Solidworks；Autocad  THE DIFFERENT MODULUS MOLD OF PLASTIC TOY GEAR OPTIMIZATION DESIGN Abstract In the production of raw matrrial,the plastic has become more and moer essential in a country .Today ,plastic gear is widely used in plaything .Adopting the plastic gear make toys quality light easy manufacture and nonhazardous ,which make people very like it .Through to analyze four different modulus gear,drawing the mold. In this mold design I adopt one mold have four cavities.In the process of pouring may occur uneven pouring phenomenon causing molding part of poor quality,I optimize the mold to assure even pouring in the processing of pouring.It assure the quality of part for volume produce.In this mold design,I detail introduction parting surface pouring,choosing molding part design,optimization design of mold and the like.In addition,I also optimise the ejection system and cooling system,to ensure the mold design meet the using condition. In this mold design,I adopt some software for example solidworks ,Autocad . Through this mold design, my using software skill have strengthen and in-depth knowledge of mold design ,experience the mold design workers life and problem. KEYWORDS: the design of injection mold, the gating system,Solidworks, Autocad 前言 在今天通过对一个国家的塑料消耗量的评估和塑料在工业中运用面的广度，作为评价这个国家工业方面发展水平高低的手段之一 。塑料已成为国民经济生产必不可少的原材料，塑料制品的玩具在今天也很常见，玩具汽车等一系列儿童娱乐用品极大地丰富了儿童的童年生活，塑料玩具因其质量轻，安全，无毒害而深受喜爱。现在越来越多的塑料玩具的出现，为塑料行业带来了腾飞。 随着工业生产的产品塑料化的程度的不断增强以及对塑料制做成的物品（塑件）的广泛应用与不断发展，塑料类的模具行业将会在未来拥有更
