摘要： A die assembly for extrusion molding of profile shapes is rigidly mounted on the press ram and includes two coaxially arranged parts. The first part is a holder having the free cylindrical end portion provided with an external thread of which the axial extent is limited by a radial shoulder. The other part is a cylindrical nut threaded onto the free end portion of the holder, so that an axial gap is left between the face end of the nut and the radial shoulder of the holder, with this gap being intended to be taken up in the course of an extrusion mold operation, whereby the die assembly provides for a variation of the external diameter thereof, and the cylindrical shape of the external periphery of the die assembly being unaffected by this variation of the diameter.
