Finite Element Analysis and Topology Optimization Design for Front Platen of Injection Molding Machine

Abstract:

The weight of platens accounts for about 70% of the entire clamping device of injection molding machine. The reduction in the weight of platen means the reduction in the cost of injection molding machine. UG NX8.0 was adopted to conduct the parametric design, and UG NX8.0 Advanced Simulation module was adopted to conduct the finite element analysis and the topology optimization design for the front platen of injection molding machine so as to obtain the quantitative conclusions that the volume of platen is reduced and the stiffness as well as the strength is improved. The maximum deformation of platen is decreased by 6.2%, the volume is decreased by 6%, the maximum stress is decreased by 6.6% and the average displacement of all the nodes in the mold mounting plane is decreased by 9.1%. The effect of optimization is obvious.
