Abstract
A variable volume metal delivery system for a die casting machine. The system includes a shot sleeve having a plunger propelled by a shot cylinder. A stroke adjustment rod operated by a second cylinder extends into the shot cylinder to define the backward stroke limit of the shot cylinder and consequently that of the plunger. The stroke adjustment rod is movable by means of the second cylinder between a high-volume position, permitting a relatively long stroke, and a low-volume position, providing a relatively short stroke. Accordingly, the volume of the shot sleeve can be changed easily, for example, to accommodate the manufacture of articles either with or without structural inserts.
