设计简介
摘要
塑料工业是当今世界上增长最快的工业门类之一，而注塑模具是其中发展较快的种类，因此，研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。本文的课题是游标卡尺盒注塑模具设计，文中首先对注塑件进行结构、工艺分析，然后通过测绘确定出了塑件的零件图。在已知塑件材料为PP1340的情况下，确定了PP1340的收缩率、塑件的尺寸精度、塑件的表面质量及成型的工艺参数，最后根据这些参数确定了注塑机的类型。在模具设计过程中，首先对分型面及型腔的数目进行确定，选择模架后分别对浇注系统、浇口、导向定位机构、滑块、顶出系统、排气系统、冷却系统进行设计。模具的初步设计完成后，用Solid works软件中的塑料顾问分别对浇口位置、塑料填充、冷却质量、注塑压力等进行分析，来验证模具设计的要否所合理，从而完成模具的设计。

Abstract
In now days, plastic is one of the quickest growing industry of the industry classes in the world, but injection mold is the part of cases what grow more fast. So studying the knowledge of injection mold is good to know more about the process of plastic products, and it also makes sense to improve the products quality.This article is about the injection mold design and this design is for a product of calipers box. Firstly, it produces the molding’s structure and technology, and then draw the detail drawing through mapping. In the case of knowing the mold material which is PP1340, the article makes sure of shrinkage, dimensional accuracy, surface quality and technological parameter of molding. At last, on the basis of those parameters choose a right injection molding machine. In the process of design, at first, it makes sure the numbers of molding sand and the location of parting surface. After choosing the moldbase, start to design gating system、pouring gate、guide rail system、sliders、ejection system、exhaust system、cooling system. After finishing the first step of design, using plastic advisor of a part pro/engineer analyses gate location、molding filling、colling quality、injection pressure and so on to make sure the design is or not right. If everything is ok, then finish the design.
