摘要当今塑料工业的发展十分迅速，逐步成为了当今世界上发展速度最快的工业 之一。而对于注塑模具，在塑料工业发展中也是比较快的，因此，在注塑模具这 一方面的研究，对获得高质量的塑料产品和塑料工业的快速发展豆有着十分重要 的意义。75751

本文主要是对 5026 活动盖板注塑为例，对其注塑成型过程进行设计，较少了 5026 活动盖板注塑模具分型面的选择，浇注系统、冷却系统以及推出机构的 设计过程。对模具的强度要求进行了说明，注塑机的选择及其相关参数的验证， 包括了模具分型面的选择、开合模行程、模具的安装尺寸、模具的各零件尺寸大 小的选择等。在这些步骤完成后，又要对塑件的生产过程进行优化设计，既要充 分保证塑件产品的质量，又要保证生产过程中的经济性。

最后则是对注塑模具装配的设计，包括注塑模具装配的步骤、注意事项等等。 通过这次对 5026 活动盖板注塑模具的设计，可以在注塑成型这一方面有个

简单的认知。对于注塑模具的设计过程中的存在的某些细节问题以及注塑模具的 某些结构和工作原理也会有一些了解；通过对 UG、AutoCAD 的学习后，可以建立 一些相对简单的零件的零件库，对提高设计的工作效率有了很重要的意义。

5026 Activities Cover Injection Mold Design

Abstract Plastic industry in today's world in rapid development, has become one of the fastest growing industrial categories in the world。 And injection mold, it is a kind of rapid development of plastic industry, therefore, the study of injection molds, for to improve the quality of plastic products and the development of the plastics industry has important significance。

This article mainly to 5026 cover-plate injection as an example, the design of the injection molding process less 5026 activities cover the injection mold parting surface selection, the design of gating system, cooling system and launch mechanism process。 To mold to illustrate the strength requirement, the choice of injection molding machine and related parameter validation, including the mold parting surface selection, process schedule, the installation of mold size, mold and the choice of the size of each parts。 After these steps are completed, and to optimize the production process of plastic parts design, to fully guarantee the quality of plastic products, and to ensure that the economy in the process of production。

The last is the design of injection mold assembly, including injection mold assembly steps and matters needing attention and so on。

Through this to cover 5026 activities of injection mold design, can have a preliminary understanding of injection molding。 For some detail problems in the process of injection mold design and injection mold structure and its working principle is also there will be some understanding; Based on the study of UG, AutoCAD, can set up some relatively simple parts of parts library, to improve the work efficiency of the design has the very vital significance。

Key words: plastic plastic injection mold cover plate
