Numerical Simulation of Semi-Solid Die Casting Technology of Bearing Cage

Abstract

Semi-solid die casting instead of conventional casting was used to produce bearing cage, Model of semi-solid die-casting was established based on power cut-off (PLCO) model and ProCast 2008 to simulate the effects of processing parameters on deformation process, through orthogonal experiment and analysis of defects, the reasonable technological parameters for using A356 aluminum alloy to finish semi-solid die casting of bearing cage were obtained: the pouring temperature was580°C, the preheating temperature of the mould was 200°C, and the injection velocity was 20 mm/s.
