摘要：便携式工具盒在我们日常生活中有着广泛的应用，尤其是近年来，便携式的产品越来越成为家庭必备的工具，市场需求也逐年递增。注射成型的技术是在生产便携式工具盒中最核心的技术之一，这里研究注塑成型的工艺优化、模具设计的制造技术对获取更高质量的产品有着重要的实践意义。48118

本模具设计以便携式工具盒为研究对象，在快速流模的基础上，应用UG三维制图软件，进行注塑模的模具设计。

本设计分析了工具盒的注塑工艺性，确定了注塑工艺的参数，选用了J54-S200/1400型注塑机，并对最大注射量、开模行程、注射压力、锁模力等进行了计算校核。

进行了工具盒的三维设计，包括了主流道、分流道、浇口和冷却系统等等进行了重新设计，同时，成型零部件的结构设计、导向结构设计、排气系统设计等等，最后通过各种校核，使得模具的可生产性大大提高。

Analysis and die design of the cover forming process of the portable tool box

Abstract: portable tool box in our daily life has a wide range of applications, especially in recent years, more and more portable products become a family tool, the market demand is also increasing year by year. Injection molding technology is one of the core technology in the production of portable tool box, this paper studies optimization of injection molding process and mold design and manufacturing technology to get more high quality products have important practical significance.

The mould design of injection mold design of the mold to portable tool box as the research object,in the fast flow model based,using UG three-dimensional mapping software. Mold design process to design molding parts, casting system,cooling system, the side core pulling mechanism, the introduction of institutions and so on.

The design analysis of the process of injection molding tool box, determine the injection molding process parameters, selection of the J54-S200/1400 type injection molding machine, and the maximum amount of injection, mold opening stroke, injection pressure, lock clamping force etc. is calculated and checked.

The three-dimensional design of the tool box, including the mainstream Road, a branch road, gate and cooling system, and so on were redesigned. At the same time, the structural design of molding parts, guide structure design, exhaust system design, and so on. Finally, through various checking, the mold can greatly enhance the production of.
