Abstract

PURPOSE:To surely obtain the mold of the required hardness even if the height of the pattern part is high by dividing filler charging to two or more times and blowing compressed gas at every time of these at the time of charging fillers into the spacing composed of a molding flask and pattern plate and making these to a higher density by compressed air and squeeze operation. CONSTITUTION:Molding sand 11 for molding green sand mold is charged at a suitable amount into the spacing 10 formed by a pattern plate 1 and molding flask 5. Next, compressed air is supplied into the spacing 10 and is blown from the top surface of the sand 11 so that it is passed through vent plugs 4, 4 and fine holes 3, 3 and is exhuasted to the atmosphere. Along with the flowing-through of this compressed air in the sand 11, the sand 11 is moved in the directions of plugs 4, 4 and is packed to a high density. Next, a suitable amount of the molding sand 11a of exactly the same quality as that of the foregoing sand 11 is charged and compressed air is blown in the same manner as before. This is repeated to pack the molding sand into the spacing 10, after which squeeze action is given by a pressure plate and pattern plate 1, whereby the molding sand is solidified, after which rapping is done.
