Simulation Analysis and Optimization of Die-Casting for Automobile Steering Valve Shell
摘要
Abstract
The topic of issue was aimed at the problem of many of the defects of shrinkage and surface porosity of automobile steering valve shell in practical casting production,which can result the low passing of the products of the valve body,so the filling and solidification process of the die-casting were numerically simulated by using the Anycasting software.According to the simulation results,the causes of the problem were analyzed and measures for improvement were put forward.By means of changing the feeding mode of the gating system and exhaust structures,at the same time setting up the additional cooling system in the mold,the simulation of improved scheme indicated that pores on the convex parts of binding sites disappeared,and islanding in thick wall area was significantly reduced. The improved process was verified by the actual production,the simulation results were in agreement with the production,and the yield of the product obviously increased.关键词
