【摘要】：随着塑料工业的飞速发展,塑料产品依靠其优良的加工性能及使用性能已经在汽车、家电、物流、医疗器械、航空航天等领域得到了广泛的应用,并逐步呈现出“以塑代钢”、“以塑代木”趋势。塑料产品从其结构设计到产品成型是一个集设计、制造、工艺调试等多工种的复杂过程,任何一个环节对产品的质量都会产生较大的影响。随着塑料模具CAD/CAE技术的不断发展,颠覆了传统模具依靠经验设计与制造的方式,合理运用CAD/CAE技术能够在产品与模具结构设计阶段尽早的发现问题并及时解决,有效的缩短了产品的设计周期,降低了企业的成本。本文以杯框架系列产品为例,基于UG和Moldflow研究模具CAD/CAE技术在塑料产品结构设计、模具结构设计、注塑成型工艺优化中的应用,旨在将产品结构、模具结构、工艺调试三个过程能有效的联系起来,提高产品的开发效率,使塑料产品生产周期尽可能的缩短。主要研究内容有以下几个方面:(1)以UG8.0为设计平台,以Workbench14.5为分析工具,结合塑料产品结构设计的一般准则,设计杯框架系列产品的结构,建立其三维模型,最后利用Moldflow对其产品进行填充质量评估。(2)首先利用Moldflow分析优化最佳浇口位置以及最佳冷却回路布局,然后利用UG8.0/Mold Wizard模块和HB_MOULD相结合,依据模具设计基本原理,对杯框架系列产品进行模具结构设计,其中包括模架系统选取、动定模以及滑块设计、热流道系统、冷却系统、排气系统、顶出系统及其辅助件设计等。最后得到杯框架的的模具总体装配图。(3)基于Moldflow软件的注塑成型过程模拟,包括填充、冷却、保压、翘曲等过程的模拟分析,并优化注塑成型工艺,得出最佳成型工艺参数,并将其工艺参数转化为实际的注塑工艺条件,为试模师试模提供科学依据。通过对本课题的研究,说明合理的利用模具CAD/CAE技术可以大大提高了塑模企业的产品结构、模具设计、注塑工艺调试三个部门的协同工作效率。为企业提供了一种高效的方法,推动了注塑模具CAD/CAE技术的发展。
[Abstract]:With the rapid development of plastic industry, plastic products have been widely used in the fields of automobile, household appliances, logistics, medical equipment, aerospace and so on. "plastic instead of wood" trend. Plastic products from its structure design to product molding is a complex process of design, manufacturing, process debugging and so on. Any link will have a great impact on the quality of the product. With the continuous development of plastic mould CAD / CAE technology, the traditional mold design and manufacture method is overturned. The rational use of CAD / CAE technology can find the problem and solve the problem in the product and mold structure design stage as soon as possible. Effectively shorten the product design cycle, reduce the cost of enterprises. In this paper, based on UG and Moldflow, the application of CAD / CAE technology in plastic product structure design, mold structure design and injection molding process optimization is studied based on UG and Moldflow. The three processes of process debugging can effectively link up, improve the efficiency of product development, and shorten the production cycle of plastic products as much as possible. The main contents of this paper are as follows: (1) with UG8.0 as the design platform, Workbench 14.5 as the analysis tool, combined with the general criteria of plastic product structure design, the structure of cup frame series products is designed and its three-dimensional model is established. Finally, Moldflow is used to evaluate the filling quality of its products.) first, Moldflow is used to analyze and optimize the optimum gate position and the optimal cooling circuit layout, then the UG8.0 / Mold Wizard module is combined with HBSMOULD, and according to the basic principle of mould design, Die structure design of cup frame series products includes mould frame system selection, dynamic mode design and slide block design, hot runner system, cooling system, exhaust system, ejection system and its auxiliary parts design. Finally, the overall assembly drawing of the cup frame is obtained. (3) the injection molding process simulation based on Moldflow software, including the simulation analysis of filling, cooling, keeping pressure, warping and so on, and the optimization of injection molding process are obtained, and the best molding process parameters are obtained. The process parameters are transformed into actual injection conditions, which provides scientific basis for mould testing. Through the research of this subject, it shows that the rational use of CAD / CAE technology can greatly improve the efficiency of collaborative work in three departments: product structure, mold design and injection molding process debugging. It provides an efficient method for enterprises and promotes the development of CAD / CAE technology.
