ABSTRACT:
A horizontally movable die has a bottom slide and cooperates with a stationary die in a die casting machine, which machine has a vertical injector for molten metal mounted underneath the dies and oscillatable to an acute angle to the vertical from under the dies for filling with molten metal. The outwardly movable shot sleeve of the injector seats in two semi-annular docking blocks, one mounted in the stationary die and the other mounted on an outward projection or extended portion of the slide on the movable die. Thus, when the dies are closed, the two semi-annular docking blocks for the shot sleeve form an aperture completely within the stationary die, which aperture communicates with an outwardly tapered trough duct that extends to the casting between the dies. This trough configuration forms a sprue in the stationary die that permits the separation of the movable die from the stationary die and then the retraction of the bottom slide without obstruction by any part of the sprue or the casting. This configuration also enables the vertical injector's shot sleeve to be injected between the stationary die and a bottom slide on the movable die. Additional slides may be employed on the movable die, and ejector pins are preferably provided in the movable die for ejecting the casting after the dies and slides have been retracted.
