Definitions

  • the invention relates to a method for producing foundry molds in successively arriving mold boxes, each box being moved upwards out of its feed path by a model plate carrier arranged in a transfer device and taking a filling frame into a filling station, lowered after filling and through move the transfer device under a compression station, then drive it up, compress it and lower it again, separate it and move it away via a discharge path.
  • the known system requires an auxiliary vessel, the volume of which approximately corresponds to the molding space formed from the molding box and filling frame, and because of this auxiliary vessel, large lifting movements of the model plate carrier, that is to say, work with correspondingly complex lifting tables, are required.
  • the present invention is therefore based on the object of specifying a method and a device for producing foundry molds with the features mentioned at the outset, which is distinguished on the one hand by a higher hourly output and on the other hand by a low outlay on equipment.
  • this object is achieved according to the invention in that the filling frame is separated from the box after the compression process, but before the box is placed on its discharge path, and is returned separately to the filling station.
  • the invention is realized in that a further transfer device for the filling frame is arranged above the transfer unit for the model plate carrier.
  • This transfer unit preferably has adjustable holding elements which can be moved into a holding position or out of this path into a rest position during the lifting movement of the filling frame in its path. This ensures that the filling frame in the filling station can be removed from the transfer device upwards, but after the filling process can be lowered past the transfer device downwards and that it can equally pass the transfer device in the compression station, but after the compression process it is held by it and is separated from the molding box.
  • the transfer device for the filling frame can be designed as a linear exchange unit or also as a swivel arm, a rotary changer, in particular a turntable, is recommended for the transfer unit of the model plate carrier.
  • This transfer unit also handles the transport of the boxes between the incoming and outgoing roller conveyor.
  • a filling station 2 and a compression station 3 are mounted in a common frame 1.
  • Roller conveyors 4 and 5, which extend perpendicular to the plate plane, serve to move the empty mold boxes 6 or to remove the molded mold boxes 7.
  • Both roller conveyors are in the area fold the side of the filling station and the compression station so that the mold boxes can be moved freely in the vertical direction. This method is carried out by means of a lifting table 8 assigned to the filling station and a lifting and external table 9 assigned to the compression station and therefore of a stronger design.
  • a rotary table 10 is mounted in the center between the two lifting devices. It contains two receptacles offset by 180 ° for the model plate carriers 11 and 12.
  • a transfer device 13 for the filling frame 14 is arranged above the turntable 10 and coaxially with it. It transports the filling frame 14 back to the filling station 2 after the compression process. Their structure will be explained in more detail later.
  • FIG. 1 shows in the upper area of the filling station a sand container 15 which is arranged above the lifting table 8 and which has a flap closure or the like at the bottom in order to fill the sand into the molding box and filling frame.
  • a pressure vessel 16 is indicated, with which the filled sand is compressed in a known manner by a pressure pulse.
  • a pressure vessel 16 is indicated, with which the filled sand is compressed in a known manner by a pressure pulse.
  • the system functions as follows: An empty molding box 6 runs into the filling station in a known manner via the roller conveyor 4.
  • the lifting table 8 lifts the model plate carrier 11 out of the turntable 10, takes over the molding box 6 from the roller conveyor 4 and then the filling frame 14 from the transfer device 13 and drives these stacked parts close to the underside of the sand container 15. While the model plate carrier is being filled 11, molding box 6 and filling frame 14 existing molding space with sand, the roller conveyors 4 and the holding elements of the transfer device 13 are pivoted outward so that the molding unit can be lowered back onto the turntable 10 unhindered.
  • the transfer device consists of two parallel pivot arms 13a and 13b, the spacing of which is somewhat greater than the length of the filling frame 14.
  • horizontally pivotable holding elements 17 and 18 are mounted on the swivel arms, which correspond to projections 19 and 20 of the filling frame.
  • Fig. 4 shows these holding elements in their pivoted-back rest position, in which the filling frame can be moved vertically undisturbed.
  • FIG. 5 shows a holding element 18 pivoted into its holding position, in the bore 18a of which a guide pin 20a of the projection 20 engages from above.
  • the filling frame is held in a form-fitting manner, but can be moved upwards by the lifting ram 8.
  • the holding elements 17 and 18 are actuated, for example, by a pneumatic cylinder which is integrated in the sequence control of the system. Another drive can also be used instead.
  • the holding elements 17 and 18 are therefore in the position shown in FIG. 4, and the roller tracks 4 are also pivoted away, so that the lifting table 8 can move down with the entire molding unit.
  • the molding unit is then moved through the turntable 10 through 180 ° into the compression station and at the same time the transfer device 13 brings the filling frame 14 previously removed from the compressed molding box back into the filling station, while a new, empty molding box arrives there.
  • the filled molding unit is now moved upwards from the lifting and shaping table 9, the roller tracks 5 and the holding elements of the swivel arms 13a and 13b located in the compression station being pivoted outwards.
  • the impression unit is then pressed against the pressure vessel 16 so that the pressure pulse can be triggered.
  • the lifting movement described at the beginning is repeated in the filling station with the next molding box, which is completed with the filling frame which has previously been pivoted out of the compression station.
  • the functional sequence described shows that the separate filling frame transport by the transfer device 13 makes it possible to stack the model plate carrier, mold box and filling frame on top of one another and to fill them on the one hand and to compress and stack the parts mentioned in one stroke movement, always simultaneously a molding box in the filling station and a molding box in the compression station are treated.
  • the molding plant according to the invention achieved therefore significantly higher hourly output than in the known case.
  • it is characterized by unproblematic and in principle proven construction elements.
