ABSTRACT:
The system includes a shot sleeve having a bore and a transverse fill hole communicating with the bore. A closure member is rotatably mounted on the shot sleeve and defines a window. The closure member rotates between a fill position in which the window is aligned with the filling hole and a casting position in which the closure member seals the filling hole. Any excess molten material from the fill is poured from the closure member as it rotates. Preferably, the closure member is mounted eccentrically with respect to, and intersects, the bore. In this case, the closure member defines an arcuate recess that aligns with the internal bore when the closure member is in the casting position, thereby allowing the plunger to reciprocate through the internal bore.
