Thermal-structural coupling simulation and topology optimization of injection molding machine template
In order to improve the quality and reduce the manufacturing cost of injection molding machines,the fixed and dynamic tem-plates of a 1 600 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.
