ABSTRACT:
A flaskless molding method, wherein a match plate (5) is held between an upper flask (2) and a lower flask (3) and squeeze plates (6) and (7) are inserted into the openings of the upper flask (2) and the lower flask (3) to form an upper manufacturing space and a lower manufacturing space with initial volumes. A foundry sand is filled in the upper and lower manufacturing spaces with the initial volumes through the supply ports of the flask (2) and (3) (first filling). Next, the squeeze plates (6) and (7) are retreated to expand the upper and lower manufacturing spaces more than the initial volumes. The foundry sand is filled again in the expanded upper and lower manufacturing spaces through the supply ports (second filling). After the second filling is completed, the squeeze plates (6) and (7) are advanced to compress the foundry sand in the upper and lower manufacturing spaces so as to manufacture the upper and the lower flasks stacked on each other.
