Finite Element Analysis and Optimal Design for Mold Shelf of Powder Molding Press

摘要

Mold shelf of powder molding press (PMP) is the main load component. Control the deformation of mold shelf is a key problem. In this paper, based on the basic theory of finite element analysis (FEA), the constraints and load conditions of main support parts of mold shelf were simulated and analyzed. ANSYS software optimized the structure of mold shelf. Top width of the stress part increased to 15 mm, its height from 80 mm down to 50 mm. The results showed that the maximum displacement of mold shelf reduced to 0.4740 mm, the maximum stress reduced 843.44 MPa to 742.38 MPa. Load distribution of the mold is more uniform, deformation and displacement also improved. It provides a new method and theoretical basis for optimal design of powder molding shelf.
