Abstract
PURPOSE: To make the molding of a thin-walled hollow core easy by providing a discharge port to the lower part of the blow-in port in the upper part of a pair of heated and separable metal molds thereby blowing shell and from the upper part and discharging the same from the lower part.
CONSTITUTION: The movable metal mold 8 of metal molds 7, 8 having been heated with a heater is clamped to a stationary metal mold 7 by a cylinder 19. Next, the sand discharge port 13 of the metal molds 7, 9 is closed by a cover 48 with a lever and a blow head 35 is lowered by a cylinder 33 and is allowed to contact closely with the blow-in port. Thence, the compressed air in a tank 41 is supplied to the blow head 35 to blow shell sand into the metal molds 7, 8, after which the blow head 36 exhausts the compressed air and ascends. Next, the cover 48 of the sand discharge port 13 is opened by the lever to allow the unfired shell sand to fall by gravity. Thence, when the metal mold 8 is parted from the metal mold 7 by the cylinder 19, the hollow core moves rightward together with the metal mold 8. The projecting rods 27, 28 of a frame 3 abut on a connecting plate 25 and ejector rods 21, 22 eject the hollow core from the metal mold 8.
