摘　　要：通过对缸盖罩盖零件结构特点分析,提出双面侧浇道和单侧梳状浇道两种浇注系统方案,并以AnyCasting铸造模拟软件为基础模拟分析了两种浇注系统。结果显示,单侧梳状浇道能够满足铸件质量需求,双侧浇道填充过程中存在卷气情况,无法满足铸件质量需求。结果还显示,双侧浇道各个内浇道高速填充速度由下而上依次增大,且每个内浇道速度受其他浇道影响,上下波动范围较大,铸件填充过程不稳定。生产结果显示,单侧梳状浇道铸件满足VW50097-D5的孔隙度要求。The two kinds of gating system,double side gates and single side comb gates,for die casting of the cylinder head cover,were designed and simulated with the AnyCasting simulation software.The results show that the single side comb gate pouring system can meet the casting quality requirements,while the double side runner system cannot meet it because of air entrainment in the filling process.The results also show that in the filling process of double side gates,the filling speed increases from the bottom to the top,and they interacts with each other.Therefore,the filling process is unstable.Practical results verified that the the cylinder head cove die castings produced by the pouring system with the single side comb gates can meet the porosity requirements of VW50097-D5.
