Abstract
The machine includes a carriage assembly supporting a shot sleeve and shot cylinder at a fixed angle relative to vertical. The sleeve follows a first straight line path from a remote position to an intermediate position aligned with an aperture of the die casting die and a second path to a position communicating with the aperture. Docking cylinders lift the shot cylinder, sleeve and a docking plate to a position at which the docking plate is aligned with locking cylinders and to bring the sleeve into engagement with the die aperture. Actuation of the locking cylinders moves the docking plate into engagement with a sleeve frame supporting the shot cylinder which is thereafter actuated to eject molten metal from the sleeve engaged to the die aperture.
