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.

A method for casting metals comprising the steps of: (a) providing a die defining a cavity, an aperture communicating with said cavity and a sleeve for receiving metal in a molten condition, said sleeve having a tip positioned for longitudinal movement therein from a retracted position to an extende

A method for casting metals comprising the steps of: (a) providing a die defining a cavity, an aperture communicating with said cavity and a sleeve for receiving metal in a molten condition, said sleeve having a tip positioned for longitudinal movement therein from a retracted position to an extended position; (b) disposing said sleeve at a fixed angle relative to vertical; (c) moving said sleeve along a first straight line path from a first position remote from said die aperture to an intermediate position aligned with said aperture and thereafter along a second path from said intermediate position to an engagement position communicating with said aperture while maintaining the sleeve at said angle; (d) placing molten metal into said sleeve when said sleeve is in said first position and said tip is in said retracted position; and (e) moving said tip to said extended position while said sleeve is in said engagement position to inject the molten metal into said cavity. In a machine for die casting molten metal in a die through an aperture, said machine including, (a) a first movable support, (b) a sleeve mounted for movement with said first movable support, said sleeve having an upper end for receiving said molten metal, (c) a first power means for moving said first movable support in a generally upward direction, (d) a second movable support above said first movable support positioned to be carried thereby upon movement of said first movable support in said generally upward direction, said second movable support being mounted for movement independent of said first movable support, (e) a second power means for moving said second movable support, and (f) a shot cylinder having a rod extending therefrom, a shot arm and tip extending from said rod and into said sleeve, said shot cylinder mounted for movement with said second movable support, actuation of said first power means moving said first movable support to carry said sleeve into communication with said die.
