Abstract：Pit moulding is a moulding method in which a pit below floor is used as bottom sand box( drag) and top sand box is placed over the pit. Pit moulding is mainly used for making very large castings. In order to solve the precise closing of pit shaped sand box,a new positioning device for sand box was put forward by analyzing the advantages and disadvantages of traditional closing process. The 3D software Solid Works was used to carry out 3D modeling,virtual assembly and motion simulation,and the feasibility of the device was verified,and the physical prototype model was further built. The results show that by simulating the process of sand box closing,the prototype can realize the expected function,complete the precise closing,and improve the accuracy and safety of the closing,which can provide an important reference for the manufacturing of solid prototype.
