Assembly mould structures with different motion types in squeezing casting have been visualized based on the CAD.The softwares

including the Flash and 3DMAX

were employed to simulate the motion of mould-opening

mould-closing and mould-unloading in squeezing casting

and the movement of mould structure was real-time observed in process of simulation.The simulated results show that the working process of the mould structure can be reproduced directly by the visualization

and problems in design of the mould can be considered early and then can be modified in time

so the accuracy and rationality of the mould structure can be ensured

effectively improving the designing efficiency and reducing the designing cost.
