Abstract
PURPOSE: To make casting of desired quality possible despite setting of supply air to a crucible constant by ceasing ordinary replenishing of molten metal or performing additional replenishing in succession to the ordinary replenishing every time when the molten metal level in a crucible exceeds a prescribed level range.
CONSTITUTION: After cleaning and core setting of dies 25, 19, a cylinder 24 is extended to close the upper, lower dies 25, 19. Thence, compressed air of prescribed pressure is supplied through an air supply port 16 into a crucible 3 by opening a stop valve. Thereby, the molten metal is cast via a stalk 5 into the cavities of the dies 25, 19 and is cooled to solidify. In this case, the molten metal of the same amt. as that of casting is replenished each time into the crucible 3 via a ladle. Upon repetiton of such replenishing process, the molten metal level in the crucible 3 fluctuates. This is detected with a level gage 15, and every time when it lowers beyond the prescribed level range, one time of replenishing is added in succession to the ordinary replenishing, and every time when it rises beyond the above-mentioned range, the ordinary replenishing is ceased.
