Abstract:
A die for forming a die cavity for casting a V-block for an internal combustion engine, comprisinga stationary die element including a cavity-forming surface for mounting on the stationary platen of a die-casting machine; a movable die element for mounting on the movable platen of a die-casting machine for movement into cavity-forming engagement with said stationary die element, said movable die element including a cavity-forming surface portion, and carrying a plurality of slides including cavity-forming surfaces for movement transversely with respect to the movement of the movable platen and a pair of die core pieces reciprocatable in said movable die element at acute angles between extended positions in the die cavity and retracted positions substantially within said movable die element, said movable die element further carrying a die core locking member having forward die core engaging portions, said die core locking member being reciprocatable between a forward position, where said forward die core engaging portions engage rear portions of the die core pieces in their extended positions, and a rearward position out of contact with the die core pieces, and at least one sliding lock, carried by the movable die element for movement transversely of the movement of the die core locking member between an inward position between the die core locking member and an internal surface of the movable die element, thereby locking the die core pieces in their extended positions, and an outward position free of engagement with the die core locking member.
