给出了齿形溢流槽的模型。对采用齿形溢流槽进行压铸成形试验缺陷分析统计的基础上

给出最优化生产工艺参数。发现齿形溢流槽截面积大

气体流动速度快

且通道内能快速收集铸件尾渣、尾气。

Abstract

Based on the general type of overflow

experimental defect analysis was conducted for die casting products with thin and deep fins during die casting process.The statistics and analysis of the casting defect types were listed

and the origination of these defects was described.By comparing the general type of the overflow model

the tooth shape overflow model was proposed.Based on the statistics defect rate analysis with the tooth shape overflow

the optimized process parameters with low defects were presented.Compared to the general type of overflow

the tooth shape overflow has the advantages of a larger cross-sectional area

gas flow fast

and easy to collect the casting tailings and air effectively.
