Abstract: A method for cleaning and lubricating an injection sleeve and plunger tip during a fill and injection cycle in a cold chamber die casting machine, in which the plunger tip has an annular generally arcuate recess, lubricating nozzles, lubricating conduits, and scrap exhaust conduits. Pressurized air is released into the recess during the injection cycle and debris is exhausted through the scrap exhaust conduits. Upon completion of the injection cycle, the release of pressurized air into the recess is terminated. A mixture of pressurized air and lubricant is released through the recess onto the injection sleeve during the withdrawal cycle. Upon completion of the withdrawal cycle, release of the mixture of pressurized air and lubricant into the recess is terminated.

Abstract: An injection piston, which has a plunger tip, a plunger piston ring, and a cap and bolts, attaches to an injection rod for use in an injection sleeve of a cold chamber die casting machine. The plunger tip includes a lubricating chamber, lubricating and air conduits, lubricating and air nozzles, an annular scraper ring and scrap exhaust conduits; and has a diameter which is less than the inner diameter of the injection sleeve. The plunger piston ring has an outer diameter corresponding to the inner diameter of the injection sleeve; and is secured to the plunger tip by a cap and fasteners.
