摘　　要：以手机外壳为例,利用Moldflow软件模拟分析了在最佳浇口位置区域中采用不同浇口数量时,填充时间、压力分布、气穴分布、熔接线分布、体积收缩率和翘曲变形等参数的变化,模拟分析结果表明:考虑填充时间、压力分布、气穴分布、熔接线分布等条件,采用双浇口浇注进行手机外壳注塑效果最好。模流分析能够有效地提高注塑手机外壳的工艺质量,降低模具研发制作的成本与生产周期。Taking the case of mobile phone as an example,Moldfolw software is used to simulate and analyze the process parameters such as filling time,pressure distribution,cavitation distribution,weld line distribution,volume shrinkage rate and warpage deformation with different gate numbers in the optimal gate location area.The quality of injection molded mobile phone shells can be predicted by simulation results of filling time,pressure distribution,cavitation distribution,weld line distribution,etc.,it is found that dual-gate pouring is the best scheme for mobile phone shell injection molding.Injection molding simulation is beneficial to effectively improve production efficiency and quality of the injection molded mobile phone case,and reduce the cost and production cycle of mold development and production.
