Pressure die-casting machine and process for lubricating the injection piston

摘要

Die-casting machine comprises a moving mold half (16) and a fixed mold half (14) forming a hollow chamber, a filling chamber (20) for receiving molten metal, a plunger (22) sitting on a stamping rod (38) for ejecting the molten metal, and a device for introducing a lubricant (54) for the plunger. A tube (44) or nozzle is arranged on the stamping rod and is connected to a storage vessel (52) for the lubricant via a feed line (48). An Independent claim is also included for a process for lubricating the plunger in the filling chamber of the die-casting machine. Preferred Features: The tube or nozzle is the lowest possible size. The tube or nozzle is arranged in a longitudinal groove in the stamping rod.
