Abstract

PURPOSE:To make it possible to obtain molds having a uniform hardness, by blowing the casting sand with air in a pair of molding flask facing to each other at right and left sides, and, at the same time, by press-molding the casting sand at the surface of match plate with the compression plate after the casting sand is hardened by passing compressed air through the casting sand, so that the casting sand may fill up even the shadow part. CONSTITUTION:Molding flasks 11 and 12 are moved forward with compression plates 16 and 17, and thus a sealed space is formed between the molding flasks. Casting sand feeder 35 is lowered and its outlet is fitted to inlet 10 of molding flasks 11 and 12 with pressure through opening and shutting table 36, and casting sand is blown into the sealed space with compressed air. When compressed air is supplied to the casting sand contained in molding flasks 11 and 12 through air vents 22 and 23 of compression plates 16 and 17 by opening switching valves 28 and 29 of vertical frame 3, the casting sand is moved to the surface side of match plate 13 and hardened instantaneously. After this, the hardened casting sand is hardened furthermore by pressing the sand with compression plates 16 and 17.
