Study on Die-casting Processing and Defects of Aluminum Crankcase Left Cover
摘要
Abstract
For motorcycle aluminum crankcase cover die casting wall thickness difference was big,porosity shrinkage defect problems,with the aid of the orthogonal experiment method,the die casting process was simulated,the pouring temperature,mold temperature,injection speed and slow fast injection speed on the liquid metal filling,solidification and shrinkage cavity,shrinkage porosity were studied.At the same time,the process parameters were optimized and the production experiments were validated.The results show that the time of the metal liquid filling is shortened.Increase the mold temperature,the solidification time is prolonged,the maximum solidification rate decreases.These four factors have similar influence on the casting defect,and the defect appears in the thick wall near the thin-walled shell.关键词
