Abstract

PURPOSE:To prevent the leakage of gas perfectly and produce gas molds with good effciency by sucking and supplying a curing gas into a molding flask, and allowing the same to pass through the molding sand contg. a binder thereby performing molding. CONSTITUTION:A pattern part 5 is mounted in the space delineated by a pattern board 1 and a molding flask 6, and molding sand 8 contg. an org. binder is packed therein. A shielding plate 12 is placed at the approximate center thereof, and a cover member 9 connecting to a gas producer 15 is placed thereon. Thence, a vacuum pump is operated to suck and supply the curing gas stored in the producer 15 through a conduit 14 and a cap 13 then through a gas supply hole 11 into the flask 6. The curing gas diffuses to four ways by colliding against the plate 12, passed through the inside of the molding sand 8, and is sucked away into a deodorizer through a vent plug 7, a vent hole 3, an evacuation chamber 2 and a suction chamber 16. After the molding sand 8 is allowed to cure by the curing gas passed for a prescribed time, the cap 13 is removed, the supply hole 11 is shut off, and the residual gas is removed, and this completes the molding operation.
