摘　　要：对定位支座的金属型重力铸造工艺进行设计及优化,通过公式计算,重新确定浇注系统的结构形式及横截面积,将内浇道的横截面积增加到2453 mm^(2),直浇道高度延长至120 mm。结果表明,通过优化浇注系统结构,保证铝液在充型的过程中,有足够的铝液对缺陷部位进行补缩,消除铸造缺陷,产品达到技术标准,降低生产制造过程中的费用成本,产品合格率达到95%以上。The casting process of the positioning support body was designed and optimized.The structure and cross-sectional area of the pouring system were determined by formula calculation.The cross-sectional area of the inner sprue was increased to 2453 mm^(2) and the height of the straight sprue was extended to 120 mm.The results show that the casting defects can be eliminated by optimizing the structure of the casting system to ensure that there is enough liquid aluminum to supplement the defective parts in the mold filling process.Products meet the technical standards,reduce the cost of production and manufacturing process,product qualification rate of more than 95%.
