Abstract: A method for compacting molding sand in a mold space defined by a pattern plate, which is fixed in a horizontal position when the molding sand is compacted, a leveling frame disposed for vertical sliding movement around the outer periphery of the pattern plate, a frame member disposed for vertical movement above the leveling frame, and a filling frame disposed for vertical movement above the frame member. The method comprises the steps of feeding molding sand into the mold space, primarily compacting the molding sand in the mold space from above by compacting means while at least the leveling frame is being set so that it cannot be lowered, and secondarily compacting the molding sand in the mold space from above by the compacting means while the leveling frame, the frame member, and the filling frame are set so that these elements can be lowered.
