基于Moldflow的带金属嵌件打印机板浇口优化设计

针对带金属嵌件打印机板使用传统注塑模具设计方法时，存在开发周期长、成本高且质量不易保证等缺点，采用 计算机辅助设计软件Pro/E和有限元分析软件Moldflow相结合的方法对制品进行不同浇口位置方案下的“填充+保压 +翘曲”模拟分析，从充填时间、流动前沿温度、气穴、熔接痕和翘曲变形等方面进行了综合比较和评测，确定了最佳浇口 设计方案。结果表明，应用Moldflow软件进行模拟仿真，找出了制件在不同浇口设置环境下缺陷产生的原因，从而为避 免或消除制件上的缺陷，进一步优化模具设计、降低生产成本，为指导实际生产提供合理的依据。

Design Optimization of Injection Molding Gate for Printer Board with Insert Based on Moldflow

Traditional mold design methods of printer board with insert have many disadvantages, such as long design cycle, high cost and difficult guarantee of quality. The mold flow of different gate design was analyzed by combining the computer-aided design software Pro/E and the finite element analysis software MoldFlow. Through comprehensive comparison in filled time, temperature at flow front. weld lines and warpage deformation. the best gate design was determined.The results showed that the application of Moldflow software. the reasons of defects under different gates environment were found. so as to avoid or eliminate defects on parts and further optimization mold design, reduce the production cost, provide the reasonable basis to guide the practical production.
