The Influence of Shooting Pressure Head Height and Sand Diameter on Shooting Process
In this paper,a set of visualized mold was designed to record the whole process of sand shooting with the help of high-speed camera,measure the quality of sand shooting and the maximum filling height,so as to characterize the flow and filling capacity of sand particles in the process of sand shooting.The experimental results show that the reduction of shooting pressure head and the prolongation of shooting time are beneficial to the filling of core shell.Coarse sand can complete the filling of simple and small core boxes more efficiently,while fine sand is better for large and complex core boxes.
