FIELD: metallurgy.
SUBSTANCE: core box contains two half-molds with core forming cavities. An axis is installed in the lower half-mold; a lever designed to turn is secured on the axis. A tail is made on one end of the lever, while a lug forming an undercut of the core is made on another end. After moulding of the core a drive by means of the system of levers lowers a plunger with stop. The stop runs over the lever tail forcing it to decline along the arc and to take place of the plunger. After extraction of the core the drive raises the plunger and returns the lever into the initial position.
EFFECT: upgraded quality of fabricated core.
