Abstract

PURPOSE:To make a uniform mold having sufficient hardness even for complex- shaped model board, by solidifying at a fixed hardness by squeezing after throwing molding sand in molding flask from the upper part and firmly solidifying the molding sand along the surface of model board passing compressed air through the above sand. CONSTITUTION:The measuring hopper 36, 48 are moved with the gate member 41, 49 right above the upper and lower molding flask 21, 11, carrying out stretching operation of the cylinder 39, 54 and the molding sand is thrown in the molding flask from the upper part opening each lower opening. The squeeze board 3, 25 are moved by carrying out streching operation of the cylinder 2, 24 after returning the hopper 36, 48 to the original position and each upper opening of the flask 11, 21 is shut. Compressed air is supplied in the hollow room 4, 26 through the guide bar 6, 28 and the molding sand is firmly solidified along the surface of the model board 17 jetting the compressed air in the flask 11, 21 and next, the board 3, 25 are advanced in flask 11, 21 carrying out stretching operation of the cylinder 2, 24 and the molding sand having desired hardness, is solidified.
