焊接快速接头塑料外套注射成型CAE及模具设计(本科毕业论文设计)
摘 要

一直以来,在塑料制品的所有成型工艺中,注射成型应用最广泛。在传统的注射模设计过程中,对注射成型参数的选择及模体的设计都主要依靠经验值,这样不仅不够精确,而且耗费了大量的人力和物力资源,而应用计算机辅助技术就显得颇具优越性。本文的主要研究内容为利用Moldflow进行焊接快速接头外套的注射成型工艺分析和利用CAD进行注射模设计。Moldflow是应用最广泛的注射成型工艺分析软件,它可以预测注射成型过程中产生的缺陷,从而减少试模次数,降低模具制造成本。
文中介绍了我国塑料模具行业的现状、注塑模CAD/CAE的发展;本文先采用UG对快速焊接接头外套进行了三维造型,然后采用Moldflow软件对焊接快速接头外套注射成型过程中的流动充模阶段和冷却阶段进行了模拟仿真,并预设了两种方案,分别对其结果进行了分析比较,得出最佳布局方案、最佳成型工艺参数及最佳冷却回路形式;最后,在模拟分析的基础上,设计出了合理可行的焊接快速接头外套注射成型模具。

ABSTRACT

All along, injection molding is the most widely used in all the products of the plastic forming process. In the traditional injection mould design process, the injection molding parameters of choice and the design motif are mainly relying on the experience of value, not only imprecise, but spent a lot of human and material resources, and the application of computer-aided technology it is quite Superiority. The main research for the use of Moldflow quickly welded joints jacket of the injection molding process of vaccination and the use of CAD die design. Moldflow is the most extensive application of the injection molding process analysis software, it can be predicted injection molding process of the defects, thereby reducing the number of trial and lower mold manufacturing costs.
In this paper, plastic mold of China's trade status quo, Injection Molding CAD / CAE to the development of this first use of the rapid UG welded joints jacket for a three-dimensional modeling, and then use Moldflow software welding joints jacket rapid injection molding process of filling the flow-stage And cooling phases of the simulation, and the default of the two programmes, respectively, the results were analyzed, that the best layout of the programme, the best treatment process parameters and the best form of cooling loop; Finally, in the analysis of the simulation On the basis of a reasonable and workable design of the welding joints jacket rapid injection mold.


Key words: injection molding, mold design, Fast welding joints jacket
