Abstract

The invention relates to a plunger for a cold chamber diecasting machine in whose casting cylinder (3) the plunger (1) defines a pressure chamber (5) for the molten metal in an axially displaceable manner. The plunger (1) has a plunger base (7) and a sealing ring (17) that is fixed in the range of the pressure chamber-side plunger front in an outer annular recess (19) of the plunger base (7). The plunger base (7) axially projects beyond the sealing ring on the pressure chamber side and radially extends on the pressure chamber side across the sealing ring across a part of its radial thickness. The plunger base (7) can be cooled at least in the area of its plunger front (15). The sealing ring (17) is movably disposed with a radial and axial play in the annular recess (19). A projection (43) of the plunger base (7) that radially extends across the sealing ring (17) defines with its outer peripheral surface (46) an annular gap (47) between itself and the casting cylinder, said annular gap being cooled to solidification temperature during casting. The melt that solidifies in the annular gap (47) additionally seals the sealing ring (17) and prevents the melt from reaching the play of the sealing ring (17) or getting between the sealing ring (17) and the casting cylinder (3), thereby reducing wear of the sealing ring (17).
