An improved method and device are proposed for forming upper and lower molds having no flask.A match plate is put between the upper and lower molds having intakes for foundry. The upper and lower molding space is defined by inserting an upper and a lower squeeze means into openings of a pair of the upper and the lower flask having no match plate, the pair of the upper and the lower flask and the match plate are rotated and moved so that they are perpendicularly positioned, moving them so that the intakes of the upper and the lower flask move upward.The upper and lower molding space is filled with the foundry sand. The foundry sand is squeezed using the squeeze means. The pair of the upper and the lower flask and the match plate are rotated so that they are horizontally positioned. After that the match plate is removed.The core is installed between the upper and the lower molds, if necessary, and matching the upper and the lower flasks extracting the molds from the upper and lower molding flasks. |
