ABSTRACT:
A die casting machine comprises a die cavity, a sleeve communicating with the die cavity, and a piston which reciprocates within the sleeve to inject molten metal through the sleeve into the die cavity. The piston includes a stem portion having a passage which communicates with the interior of the sleeve. An air supply system is adapted to communicate with a source of pressurized air and with the stem portion passage to selectively deliver a stream of pressurized air into the sleeve through the stem portion passage. A lubricant supply system is adapted to communicate with a source of lubricant and is operatively connected with the air supply system for introducing lubricant into the air stream for delivery by the air stream into the sleeve. A cleaning fluid supply system is provided to selectively flush cleaning fluid through the lubricant and air supply systems and the stem portion passage.
