Abstract

PURPOSE:To reduce the capacity of a cylinder through blowing a high pressurized air into the blow tank without giving any action to a sealing slider, by providing an air inlet and outlet to the sealing slider within the cylinder provided with air inlet, and press-contacting the same to the blow tank with the cylinder. CONSTITUTION:Sand 15 is charged into the slit cylinder 11 of a blow tank 10, and a sealing slider 4 is press-contacted to the blow tank 10 with a small cylinder 7. When blowing air is blown through an air inlet 3, the air flows into the blow tank 10 from a cylinder chamber 16 through an inlet 5, an outlet 6, and the slit cylinder 11 of the blow tank 10, and packs sand 15 into the molding mold. Therefore, the pressure in the blow tank 10 is applied to a frame 1 through the cylinder chamber 16 without giving any action to the sealing slider 4, and the sealing slider 4 is as well pressed against the blow tank 10 with smaller force.
