PURPOSE:To improve the durability of sealing member in a piston by projecting the piston lever in a piston-cylinder mechanism as a driving source for lifting means toward upper direction to cause hard to sway a piston lever toward right and left directions. CONSTITUTION:A cope 3 attaching casting and the casting are separated from a drag 4 and ascended by action of a cylinder 2 (lifting means). And, a base 13 is inserted into rails 5 arranged at lower face of movable table 6 and is slidable on the rails 5. The base 13 is pushed by an action arm in a side pushing driving device 7 fixed to the base 13 and connected with the cope 3, and the cope 3 and casting are moved to a casting takeout and water cooling device. In this case, as the piston lever in the piston-cylinder mechanism is projected toward upper direction, not only the cope 3 but also the piston lever are hard to swing to right and left directions. Therefore, the sealing member in the piston is hard to wear and in this result, the durability is improved.
