PROBLEM TO BE SOLVED: To provide a sand supplying device, in which a sand blowing port needed to a position correspoding to a sand charging port in various metallic molds can easily be formed while a blowing plate is attached to the lower part of a sand tank. SOLUTION: In a molding sand supplying device for press-supplying molding sand in a sand tank 7 into a metallic mold from a sand blowing port at a blowing plate side through a charging port at the metallic mold side by abutting the sand tank 7 on the metallic mold through the blowing plate 8 fitted to the lower part thereof, a long hole 13 is formed in the blowing plate 8 and a seal member 9 is disposed on the lower surface side of the blowing plate 8. The seal member 9 is composed of a main body plate-like part 9a brought in close contact with the lower surface of the blowing plate 8 and a cyindrical part 9b for blowing the sand integrally projected with the main body plate-like part and closely inserted into the long hole 13 in the blowing plate 8, and the inner part of the cylindrical part 9b for blowing the sand leaves a portion corresponding to the sand charging port at the metallic mold side and a portion except the above portion is closed with a closing plug 20.
