1 and 2 show a mold making device according to a first embodiment of the present invention, in which FIG. 1 is a schematic cross-sectional view showing the whole, and FIG. 2 is a cross-sectional view of essential parts showing different operating states on the left and right sides. The left side shows the state where the blow tank is opened to atmospheric pressure and the mold is separated, the right side shows the state when the mold is raised and pressurized air is blown into it, and Figure 3 shows the state according to the second embodiment. A cross-sectional view of the mold making device showing different operating states on the left and right sides. The left side shows the state when the blow tank is opened to atmospheric pressure and the mold is separated, and the right side shows the state when the mold is raised and pressurized air is blown into it. This is what is shown. 1...Hopper, 2...Sand supply pipe, 3...Blow tank, 4...Sand, 13...Mold, 17...Canvas.

せてなることを特徴とする鋳型造型装置。 Sand for mold making is supplied from a hopper into a blow tank through a sand supply pipe, and pressurized air is added to the blow tank to fill the sand in the blow tank into a mold for mold making. In the molding device, a part of the side wall of the blow tank is formed of an annular flexible material, and at least one of the lower part and the upper part of the blow tank is movable up and down to change the internal volume of the blow tank. A mold making device characterized in that the internal volume of the blow tank is reduced when applying the pressurized air.
