基于Moldflow的储物盒注塑成型模拟及试验验证

对储物盒盖的注塑难点进行分析,得出模具应设计成单热流道双腔结构。选取熔体温度、注射时间、保压压力、保压时间为研究对象,利用Moldflow 2018模流分析软件,构建4因素4水平正交试验,通过极差分析,得出储物盒盖在熔体温度226℃、注射时间14 s、保压压力70 MPa、保压时间10 s的条件下,变形总量最小,为0.45 mm。对获得的最优参数进行了试验验证,验证结果表明,成型后储物盒盖整体外观良好;佐证了Moldflow 2018有限元分析数据准确,正交试验构建及模具设计合理。

Simulation and Test Verification of Storage Box Injection Molding Based on Moldflow

:It is concluded that the mould should be designed with single hot runner and double cavity structure.Solution temperature,injection time,holding pressure and holding time were selected as the research objects.By using Moldflow 2018 mold flow analysis software,constructs the four factors,four levels orthogonal experiment,through the analysis of the poor,it is concluded that storage lifted the lid on the melt temperature of 226℃,14 s injection time,holding pressure 70 MPa,the holding time under the condition of 10 s,deformation amount,the smallest is 0.45 mm.The results show that the overall appearance of the storage box cover is good after molding.It proves that the accuracy of Moldflow 2018 finite element analysis data,and the orthogonal test construction and mold design are reasonable.
