为得到最优的注射工艺参数、缩短模具设计周期、降低成本,以塑料三脚架为研究对象,利用Moldflow软件对其注射工艺参数进行了优化。首先采用Pro/E进行塑料三脚架的CAD三维造型,利用Moldflow软件的DOE试验设计分析模块获得对产品质量影响最大的因素后,采用正交试验法对其注塑成型过程进行分析模拟,最终获得了最佳浇口位置和翘曲变形量分布的准确信息,优化了注射工艺参数,并分析了翘曲变形量与熔体温度和保压压力之间的耦合关系,对提高塑件质量、缩短生产周期、提高模具设计水平具有重要的指导意义。
In order to get the optimal injection process parameters, shorten the mold design cycle and reduce the cost, the plastic tripod was taken as the research object, and its injection process parameters were optimized by Moldflow software. First of all, using Pro / E to carry out CAD three-dimensional modeling of plastic tripod, using Moldflow software DOE experimental design and analysis module to obtain the greatest impact on product quality factors, using orthogonal test method of its injection molding process simulation and ultimately obtained the most Good gate position and warpage deformation of the accurate distribution of the information to optimize the injection process parameters and analysis of the warpage deformation and the melt temperature and packing pressure coupling between the relationship between the plastic parts to improve the quality and shorten the production cycle , Improve the level of mold design has an important guiding significance.
