Definitions

  • the invention relates to a molding plant for producing foundry molds in mold boxes with at least one molding and casting track and several cooling tracks parallel to one another, the molding boxes being transportable along the tracks.
  • the invention has for its object to provide a molding system of the type mentioned, in which a continuous workflow is possible even with different mold boxes and in which a simple and reliable change of the different types of mold boxes can be made.
  • the object is achieved in that the molding and casting track is extended to a length which is such that the same number of mold boxes can be accommodated on the molding and casting track as on each of the cooling tracks.
  • the molding plant according to the invention is distinguished by a number of considerable advantages. Since the same number of mold boxes can now be accommodated on the individual cooling tracks as well as on the molding and casting track, it is possible to route all molding boxes from one cooling track over the molding and casting track and back to the cooling track without that the mold boxes of the other cooling tracks would have to be moved. It is thus possible according to the invention to create a plurality of mutually independent circulation options for the molding boxes, so that overall it is possible to use the same number of different types of molding boxes as cooling tracks are provided. Since no buffer zone is provided, there is no need to empty the buffer zone when changing the dimensions of the molding boxes. Furthermore, it is excluded according to the invention that molded boxes of different sizes are mixed up, interchanged or arranged at the same time on a cooling track.
  • a particularly advantageous development of the invention consists in the fact that the molding and casting web has the required length by means of an intermediate web.
  • the intermediate web can be arranged either in front of or behind the molding and casting web and is dimensioned in length so that a corresponding number of pairs to each other on the intermediate web assembled mold boxes can be arranged, which is adapted to the number of mold boxes, which are individually arranged one after the other on the molding and casting track, ie are in the open state.
  • the batch size of the molds to be produced is larger than the number of mold boxes that can be accommodated on a cooling track or the number of molds. This measure allows several cooling tracks to be supplied with mold boxes of the same size or with the same molds.
  • the molding and casting track comprises a mold disassembly device and a mold assembling device, wherein these devices can each be arranged in series in the area of the molding and casting track. It is thus possible to automatically open the mold boxes in order to remove the finished casting and to empty and clean the mold boxes, to form a new mold, to close the mold boxes to form a mold cavity and to carry out the casting process.
  • the molding system shown in FIG. 1 comprises a molding and cooling track 1, to which pairs of molding boxes can be fed, which, as shown in FIG. 1, are passed from right to left through the molding and casting track 1.
  • the molding and casting track 1 comprises a mold disassembly device 17 and a mold assembly device 18.
  • the mold box pairs 14 are fed to the mold disassembly device 17, which separates the individual mold boxes 15, 16 from one another, as is the case in the central region the molding and casting track shown in Fig. 1 is shown.
  • the individual molding boxes are fed to a model insertion and sand filling station (not shown in detail).
  • a compression device for the molding sand can be provided in the usual way.
  • the individual mold boxes 15, 16 then pass through a mold assembly device 18, in which the mold boxes 15, 16 are joined to form a pair of mold boxes 14.
  • the pairs of molding boxes 14 are fed to an intermediate track 6 by means of transport devices 11, 12.
  • the pairs of mold boxes are transported by means of the transport devices 11, 12 cooling tracks 2, 3; 4, 5 fed.
  • the cooling tracks 2, 3; 4, 5 each completely covered with pairs of molded boxes 7, 14, with on the cooling tracks 2 and 3, as well the same types or sizes of mold boxes are arranged on the cooling tracks 4 and 5.
  • the pairs of molded boxes pass through the cooling tracks 2, 3; 4, 5 in the exemplary embodiment shown from left to right and are fed to the transport device 10 and thus in turn to the molding and casting track 1 by means of a transport device 13.
  • the mode of operation of the molding system according to the invention is described below.
  • the individual mold boxes or pairs of mold boxes run through the molding system clockwise.
  • the space freed up is filled up at the same time by a pair of molded boxes, which leaves the intermediate web 6.
  • both the cooling tracks 2, 4, as well as the molding and casting track 1 and the intermediate track 6 are each occupied by the same molding boxes 15, 16.
  • the last pair of molding boxes located on the intermediate track 6 is fed to one of the cooling tracks 4 or 5 by means of the transport device 11.
  • the last pair of mold boxes 7 is fed to the transport device 10 and thus to the molding and casting track 1 by means of the transport device 13. Since there is a total of the same number of individual mold boxes on the molding and casting track 1 and on the intermediate track 6, As on the individual cooling lanes, all mold boxes can be replaced during a cyclical run. This can be done without manual intervention and without the risk of confusion or confusion.
  • the cooling track 5 would be completely filled with molding boxes 15, 16 after the end of the circulation, while only molding boxes 8 and 9 would be arranged on the molding and casting track 1 and on the intermediate track 6.
  • the invention is not limited to the exemplary embodiment shown, rather it is also possible to provide a larger number of cooling tracks. Furthermore, it is possible to use more than two different types of mold boxes depending on the number of cooling tracks. In the system shown in Fig. 1, it would be possible to use a maximum of four different types of molding boxes.
