The invention relates to an extrusion plate (10) for assembly on the extrusion ram of an extrusion apparatus, wherein the extrusion plate (10) comprises at least one filler piece (20) with an extrusion face (21), via which a force can be exerted on a material to be extruded. The filler piece (20) is formed conically on the external diameter thereof with an outer conical face (22) and is surrounded by a sealing ring (30), which likewise forms part of the extrusion plate and is designed, with the internal diameter thereof, such that it forms a gap (60) with the inner conical face (34) thereof and the outer conical face (22) of the filler piece (20). At least one radial gap (61) which widens conically from the inside outwards runs between the filler piece (20) and the sealing ring (30). According to the invention, the sealing ring (30) has a circumferential insertion (31) extending from the radial gap (61) into the sealing ring (30). |
