PURPOSE:To form a smooth outside surface by setting the speed of a pan to a value slightly lower than the going speed of a mold on a moving table and charging a molten metal from a molten metal charging hole of the pan into the plain mold while changing the dropping point of this molten metal successively. CONSTITUTION:A prescribed quantity of the molten metal is put in a pan 3, and a turntable 17 is rotated in this state, and a plain mold 4 placed on the table 17 is set to a prescribed position, and a truck driving device 15 is driven while continuing the rotation to move a truck 5 in the mold going direction of an arrow (a) in the same speed as the mold, and the pan 3 supported by a movable frame 6 is lifted through leading-in operation of a cylinder 13, operation of a link arm 11, etc. The molten metal is charged while directing a molten metal charging hole 3' downward by a difference of length between the link arm 11 and an arm 10, and the going speed of the pan 3 is made lower than that of the mold 4. When the pan approaches the casting completion point, the pan including cylinder 13 is restored slightly to reduce the quantity of the molten metal discharged from the molten metal charging hole 3', and the cylinder 13 and the driving device 15 are restored to return the pan to the original position.
