Abstract
PURPOSE:To use a curing gas effectively and prevent the leakage of gas perfectly by providing a reducing valve and a stop valve successively to a gas supply conduit and regulating the rate of supplying of the curing gas in sucking and supplying the curing gas into a 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 is packed therein. A cover member 9 is placed on the top surface thereof. The cover member 9 has a gas supply hole 11 and a cap 12 provided with plural pieces of suction holes 13, and is connected to a gas producer 15 by means of a conduit 14 provided successively with a stop valve 16, and a reducing valve 17 from the cap 12 side. When a vaccum pump is operated to suck air through a suction pipe 18, a curing gas is introduced through the valve 17 and the valve 16 into the cap 12, where it is mixed with the air sucked through the holes 13, and the mixture is sucked into the flask 6, from which it is removed through an evacuation chamber 2. Thereby, the rate of suction of the curing gas is regulated and the producer is used with good efficiency. This device makes molding easy as well.
