摘要
以ZM6格栅铸件为对象,利用浇注系统设计的水力学原理,采用垂直缝隙式浇道对格栅铸件低压铸造浇注系统进行了优化设计,通过ProCAST软件对浇注过程中流动场和温度场分布规律进行了模拟和分析。结果显示,采用水力学原理,增加缝隙浇道与铸件接触的面积及立筒数量,可显著提高充型效果,降低铸件凝固过程各处的温度梯度;采用优化后的浇注系统设计实现了格栅铸件的成形,配合专用磨头进行后期铸件修整,能够满足格栅铸件批量生产的要求。
The hydraulic principle of gating system design was adopted and gating system of ZM6 grid castings was optimized by low-pressure casting with vertical gap runner.The liquid flow and temperature field distribution during the pouring process were simulated and analyzed by ProCAST software.The results indicate that using hydraulic principles,increasing the contact area between the gap runner and the casting,as well as the number of vertical cylinders,the filling effect can be significantly improved and the temperature gradient at various points of the casting during the solidification process was reduced.The optimized gating system design was adopted to achieve the formation of grid castings combined with specialized grinding heads for post casting repair,meeting the requirements of quantity production of grid castings.
