Claims

[Scope of utility model registration request]

It has a mold flask that is removably disposed above and below the match plate or pattern plate, and a first seal body that comes into elastic contact with the inner surface of the upper mold flask, and is fitted so as to be movable forward and backward from the upper opening of the upper mold flask. The annular shape of each of both mold flasks is enclosed in a sealed space surrounded by a lower plate that is fitted so as to be movable forward and backward from the lower opening of the lower mold flask, and has a second seal body that comes into elastic contact with the inner surfaces of the upper plate and the lower mold flask. In a mold making machine that fills molding sand by either a blowing method or a suction method through at least one wall surface selected from among the wall surfaces, and compression molds the sand, the second seal body is configured to correspond at least to the mold conveyance direction. A seal body structure of a lower plate in a mold making machine, characterized in that the upper surface of the region is set lower than the upper surface of the lower plate.
