基于Moldflow的端套成型优化分析

Moldflow-Based Molding Optimization Analysis on Pot Head

摘要: 随着塑料工业的飞速发展和塑料制品用途的日益广泛，对模具设计的要求也越来越高。传统的模具设计方法已无法适应当今的要求，越来越多地利用软件分析技术来辅助塑料模具的设计，以提高塑件制品的质量和缩短产品的开发周期。本文利用模流分析对端套进行成型过程中最佳浇口位置分析，验证最佳浇口的合理性。在此基础上，通过对浇注、冷却以及翘曲三大系统进行数值模拟，预测塑件制品可能出现的缺陷。针对可能的缺陷，采用修正成型工艺参数和设计方案等方法提出改善意见，从而优化塑件整个成型过程。

Abstract: With the rapid development of plastic industry and the wide use of plastic product, the require-ments of mold design are getting much higher. And the traditional mold design method can’t meet current requirements. To improve the quality of plastic products and shorten product development cycle, more analysis softwares are used to assist the design of plastic mold. In this paper, the best gate location of pot head is analyzed with Moldflow in the molding process. According to the numerical simulation of the main three aspects of the pouring, cooling and warpage, the possible defects of plastic products are predicted. The modified molding process parameters, design pro-grams and other methods are utilized to improve all aspects of the corresponding problems in or-der to optimize the entire plastic molding process.
