Abstract

PURPOSE:To collapse and remove the master mold and core in a casting simply and easily by piercing holes with drills or the like in the core part of a cast mold then oscillating a molding flask with a sand tripping device. CONSTITUTION:A drill unit 4 provided with a motor 7 and a cylinder 2 for rotating and vertically moving a supporting member 5 having plural drills 6 is mounted to a gate type frame 1 provided in the backward position of a cooling line for cast molds. A molding flask 10 of a casting in which a core and a master mold are deeply buried and cannot be removed by the simple oscillations alone is carried to under the unit 4 by a roller conveyor 8. The drills 6 are lowered by extending the cylinder 2 and the motor 7 is driven to revolve the drills 6, thereby piercing holes in the master mold sand in the part right above the core, the core and the parts of the master mold buried deeply into the casting. These are oscillated in a sand stripping shop, whereby the firm master mold and core are collapsed easily and removed from the casting.
