Definitions

  • the invention relates to a press according to the preamble of claim 1.
  • the object of the invention is to provide a press for die-casting sanitary articles, in particular toilet bowls, which is also simple in the manufacture of sanitary articles which require more than two molded parts for molding and is robust and easy to use. Furthermore, easy access to all components of the press for the removal of the parts, assembly, disassembly and maintenance work is to be ensured.
  • the complicatedly shaped sanitary articles for die casting such as, in particular, toilet bowls
  • the mounting frames supporting the mounting plates in the closed position of the Press can be locked mechanically in their position.
  • the actual closing movement of the mold is applied after the mechanical locking of the hanging frame by the clamping plates being advanced relative to the hanging frame by separate drive units and thus being pressed or pretensioned in connection with the other molded parts, in particular the lower molded part, into the closed position of the mold.
  • the locking is expediently carried out by interlocking forks and eyes or tabs which are provided with transverse bores for receiving locking bolts.
  • one of the locking members interacting in pairs is expediently adjustable in its position.
  • a structurally advantageous arrangement in particular with regard to the production of toilet bowls, results from portals arranged on a cross, on which the slides are guided in a hanging manner.
  • the ends of the portals are expediently supported against the foundation by vertical stands.
  • a lifting device is expediently provided below the press stand for the lower molded part which is likewise arranged on a clamping plate, whereas, if required, an upper molded part is supported by a counterholder which is hydraulically actuated.
  • the press constructed in accordance with the invention is characterized by a simple and robust construction with good access to all components, the force absorption and force transmission of the press being optimal during the press operation.
  • the press has a central press structure.
  • Portal halves 2, 3, 4 and 5 extend radially horizontally outwards from the center of the press.
  • carriages 6 are guided, on both sides by rollers 7, which run on corresponding guide rails on the portal.
  • a hanging frame 8 extending downward from the portal is fastened to each slide 6, on each of which a clamping plate 9 is arranged for receiving the corresponding molded part.
  • the mounting plates 9 can be advanced by hydraulic cylinders 10 relative to the hanging frame in the direction of the press center designated by 1, the parallel guidance of the clamping plate 9 being ensured by a scissor structure 11 along an axis parallel to the axes of the portal halves 2 and 3.
  • the retreat Movement of the platen 9 to the hanging frame 8 takes place via 12 with retracting cylinder.
  • the clamping plates of the two other carriages 6, namely the carriage which can be moved perpendicular to the plane of the drawing according to FIG. 1, are each driven by a crank mechanism 13. These carriages 6 are also guided on both sides by rollers 7, as FIG. 3 shows quite clearly.
  • a lifting device 14 is expediently arranged in a foundation recess, which is guided along four columns 15 and carries the molding which delimits the shape formed by the molding from below.
  • the molded part is arranged analogously to the horizontally movable molded parts on a clamping plate, which can be moved relative to the lifting frame by means of a hydraulic cylinder in order to pretension the molded part from below into the closed position of the mold.
  • a hydraulically driven counterholder acts from above, the corresponding hydraulic cylinder being designated 16 in FIG. If required, the counter-holder can accommodate a molded part which, like the molded parts described above, can be preloaded via a movable platen after mechanical locking.
  • each side hanging frame 8 mechanical locking elements are also arranged, which cooperate with corresponding fixed mechanical locking elements in the press in the closed position of the press, so that a mechanical locking of the hanging frame 8 is possible in its position in the closed position of the press.
  • the locking elements are best seen in FIG. 1 visible forks 17 are formed on the hanging frame 8, into which corresponding tabs or eyes 18 engage in the center of the press structure in the closed position of the press.
  • the tabs or eyes are fixedly arranged with respect to the press structure and for this purpose are arranged, for example, on the portal frame in the middle of the press or on the counter plate which holds the hydraulic cylinder 10, which will be described below.
  • the forks and eyes or tabs 17 and 18 are provided with corresponding transverse bores 19, so that in the engaged position the locking takes place by means of a locking bolt inserted through the transverse bores.
  • a transverse bore can be seen in FIG. 2 and is identified by reference number 19.
  • the operation of the press is as follows. To close the press, the carriages 6 arranged on the portal halves 2, 3, 4 and 5 are moved by the toothed rack / pinion gear and the crank drives 13 in the direction of the press center 1 until the mold parts arranged on the clamping plates 9 come into contact with one another . At the same time, the lower mold part is raised by means of the lifting device 14, so that the mold cavity for receiving the ceramic slip is finally limited by the mold parts.
  • An infeed movement from above does not take place, rather the support from above only takes place via a counter plate, the support being effected hydraulically on the basis of a hydraulic cylinder 16.
  • the mechanical locking takes place in that the forks 17 of the hanging frame 8 which are in engagement with the tabs 18 and the lower forks 17 of the hanging frame 8 which are in engagement with tabs 21 on the lifting frame 22 are locked by locking bolts.
  • the mold is closed by moving the clamping plates 9 forward relative to the slides 6 by a limited amount and the clamping plate for the lower molding relative to the lifting frame 22, so that the clamping plates 9 with a predetermined closing pressure Arranged molded parts are pressed against each other in the system. After applying the closing pressure, the is filled Form by inserting a ceramic slip under pressure. The return movement of the platen takes place via separate retraction cylinders 12.
