Abstract

PURPOSE:To reduce charging time and to impove run and the yield of a tank- like casting by charging molten metal directly from the central part of a product cavity and sucking out the air in the cavity through the vents around the cavity. CONSTITUTION:A product cavity 2 of, for example, a boat hull is formed in a casting mold 1, and runners 3 communicating directly with the cavity 2 are formed in the several places at the center of the cavity 2. Vents 4 are formed in several places around the cavity 2. Reserving ladles 7 having stoppers 6 are installed in respective sprues 5, and a vacuum pump is connected to suction hoses 8 through air permeable refractories for stopping to the respective vents 4. The molten metal is beforehand reserved in the ladles 7 in the stage of charging and the molten metal is charged home by removing the stoppers 6 and at the same time by sucking air through the vents 4. As a result, the runners are required to be shorter as compared to bottom charging, and the yield is better. In addition, the run is faster, hence the generation of cold shut or the like is obviated and the good casting free from air inclusion is obtd.

A hot water channel (3) is formed in the product cavity, and gas (7) is installed in several places around the product cavity (3), and a hot water stopper is installed in the bamboo gas vent (4). Refractories (for example, CO
The intake hose (8) is connected to a vacuum pump (not shown) via a λ gas type block. When pouring hot water, bath water is stored in each drawer (7), and at the same time as each stopper (6) km is reached, air is drawn through each vent (4) and the hot water is poured all at once.
