基于Moldflow的MPI软件,对相机前盖注塑成型过程中与产品质量密切相关的气穴分布、熔接痕、产品最大变形等结果进行了研究。针对影响产品变形的材料因素、工艺参数和浇口形式等进行了详细的分析与优化,最终在保证满足产品质量要求的前提下,提出了一套更加合理的产品生产工艺方案。利用研究结果,可以有效地缩短产品的研发周期、模具设计周期,提高模具设计的可靠性。 Based on Moldflow MPI software, the results of cavitation distribution, weld lines and maximum deformation of the product, which are closely related to product quality during injection molding of camera front cover, were studied. According to the material factors affecting the deformation of the product, the process parameters and the gate form were analyzed and optimized in detail. Finally, a set of more reasonable product process scheme was put forward on the premise of meeting the product quality requirements. Utilize the research results, can effectively shorten the product development cycle, mold design cycle, improve the reliability of mold design.
