摘　　要：为了提高注塑制品的质量和降低注塑机制造成本,以1600 kN双曲肘注塑机的定模板和动模板为研究对象,采用传热学理论和有限元仿真分析,运用ANSYS对定模板和动模板进行了系统的热-结构耦合计算,分析了模板的温度场和热-结构耦合的影响。在此基础上运用拓扑优化方法对模板进行了轻量化设计,优化后模板的总变形量有所增加。动模板应力增加了9.94 MPa,定模板应力增加了10.27 MPa,但均在工程许用范围内,合模机构质量相较原始模型减轻了10.5%。In order to improve the quality and reduce the manufacturing cost of injection molding machines,the fixed and dynamic templates of a 1600 kN double curved elbow injection molding machine were studied.Through heat transfer theories and finite element simulation analysis,a systematic thermal-structural coupling calculation was conducted for the fixed and the dynamic templates by using ANSYS;the temperature field and the thermal-structural coupling effects were analyzed.On this basis,topology optimization methods were applied to a lightweight design of the said templates,and the total deformation of the templates increased after optimization.The stress in the fixed and dynamic templates increased by 10.27 MPa and 9.94 MPa respectively,both within the allowable engineering range;the mass of the clamping mechanism was reduced by 10.5%,compared with that of the original model.
