摘要
以汽车GPS导航外壳的整副注塑模具为研究对象,采用Moldflow和ANSYS Workbench软件对整副模具进行了热力耦合数值模拟分析。首先利用Moldflow软件进行模流分析,获得充填过程的温度、压力数据并建立有限元分析模型,其次利用ANSYS Workbench软件对整副模具进行热力分析,得到模具温度场和应力-应变分布云图。通过模拟发现,整副模具型芯位置温度和压力最高,在X轴上的应变也最大,分析结果与实际生产测量数据基本一致,实践证明该方法是可靠的,可用于指导生产。
Taking GPS navigation shell as the object,a complete set of injection molds for GPS navigation shell was analyzed by thermal-mechanical finite element method based on Moldflow and Ansys Workbench software.Firstly,the injection molding flow process was simulated by Moldflow software,which could obtain the temperature and pressure data of the filling process and establish the finite element analysis model.Secondly,the software of ANSYS Workbench was used to simulate and analyze the thermal stress-strain.Finally,the mold temperature field and stress-strain distribution cloud diagram were obtained.The simulation results show that the mold core has the highest temperature and pressure,and X-axis has the greatest strain.The analysis results are basically consistent with the actual production measurement data,and the practice proves that the method is reliable and could be used to guide the production.
