Marking device for inserting into molding tool for metal-, plastic- or rubber-processing, comprises central insert detachably insertable into molding tool in direction of axis, cylindrical annular collar, and cylindrical groove

摘要

The marking device comprises a central insert (5) detachably insertable into a molding tool (2) in the direction of an axis (4), a cylindrical annular collar, and a cylindrical groove. The central insert comprises a frustoconical outer surface. The molding tool includes a first molding surface (1), a second molding surface (6) having markings, and a frustoconical inner surface adjacent to the outer surface. The second molding surface is associated with the first molding surface. The frustoconical outer surface and the frustoconical inner surface disposed apexes are different. The marking device comprises a central insert (5) detachably insertable into a molding tool (2) in the direction of an axis (4), a cylindrical annular collar, and a cylindrical groove. The central insert comprises a frustoconical outer surface. The molding tool includes a first molding surface (1), a second molding surface (6) having markings, and a frustoconical inner surface adjacent to the outer surface. The second molding surface is associated with the first molding surface. The frustoconical outer surface and the frustoconical inner surface disposed apexes are different with respect to the axis of the central insert, and exhibit a first cone angle and a second cone angle. A straight line of the cone angles is arranged in a contact area (8). The first cone angle of the frustoconical inner surface is smaller than the second cone angle of the frustoconical outer surface. A difference between the first and second cone angles is = 5[deg] . The cylindrical annular collar is adjacently arranged to the second molding surface with respect to the axis of the central insert. The cylindrical groove adjacently arranged to the first mold surface of the molding tool. The collar and the groove form a tight interference fit. The contact area is arranged beneath a plane formed by the first and second mold surface.
