The invention is accomplished by a shot block that is located intermediate the die and the shot sleeve. Such a shot block includes a body having mutually opposed first and second engagement surfaces. The first engagement surface abuts the shot sleeve and the second engagement surface abuts the die. A passage extends longitudinally through the body and defines an opening at the first engagement surface and an opening at the second engagement surface for transmitting a molten or semi-molten metal charge under pressure from the shot sleeve, through the passage, and into the die cavity. A cooling channel within the body circulates a fluid therethrough to absorb heat from the charge located within at least a portion of said passage (i.e. the biscuit). |
