PURPOSE: Provided is a device for manufacturing mold, which enhances the dimensional precision of molds as well as solving the problem of turning the molded material. CONSTITUTION: The device for manufacturing mold comprises: a rotary transferring part which rotates to change the position of mold and the first(1) and the second(2) molding boxes when the mold and the first(1) and the second(2) molding boxes are lifted; a mold sand supplying part which supplies the wet sand to the first(1) and second(2) molding boxes; a turning over part which makes the first(1) and the second(2) mold boxes lifted and turn over so that sands are uniformly filled; a mold removing part which removes the die(3) placed between the first(1) and the second(2) mold boxes so that a mold is formed from the mold boxes filled with sands and from the turning over part; a mold sand removing part placed at the side of the rotary turning part removing the mold sand when the first(1) and the second(2) mold boxes are transferred from a position by the rotary transfer part after the molten metal is introduced into the die made by the mold removing part; and a recycling part of the mold sand which makes the mold sands re-used by transferring the moisturized mold sand to the mold sand supplying part after spraying water uniformly to the removed mold sands.
