Abstract

PURPOSE:To suck a gas easily into a molding flask and prevent the leakage of the gas by supplying the gas mixed suitably with a curing gas and air in sucking and supplying the curing gas into the molding flask. CONSTITUTION:A pattern part 5 is mounted in the space delineated by a pattern plate 1 and a molding flask 6, and molding sand 8 contg. a gas curable binder. A cover member 9 is placed on the top surface thereof. The member 9 is connected via a supply hole 11, a cap 12, a gate valve 15 and a conduit 16 to a gas mixer 14. The mixer 14 is connected via a constant flow pump 18 to an amine soln. storage tank 19, and is connected via vent holes 13, a valve 25, and a supply hole 24 to the atmosphere. When air is sucked through a suction pipe 26 by operating a vacuum pump and a constant volume of a gas is fed by the pump 18, the mixed gas of the amine soln. and air is formed in the holow chamber of the mixer 14, and is supplied via the stop valve 15 and the cap 12 into the flask 6. Thereby, the gas is easily sucked into the flask 6.
