The invention relates to a calibration plate (17) for a shaping device with end faces (30, 31) spaced at a distance apart from one another, extending between which is at least one aperture (24) with shaping surfaces (25) through which an extruded article is fed. At least one recessed receiving orifice (27) is provided in the calibration plate (17), in which a wear-resistant insert (28) with a retaining part (33) is inserted. Delimiting surfaces (29) of the receiving orifice (27) and external surfaces (35) of the retaining part (33) form a guide arrangement (36) at least in certain regions. Co-operating limiting stops (37, 38) with stop surfaces (39, 40) for the guide arrangement (36) are provided around a major part of a peripheral region, both in the region of the receiving orifice (27) and on the retaining part (33) and are provided with stop surfaces (39, 40) for the guide arrangement (36). |
