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. |
