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 moved 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 must have adjustable holding elements which can be moved into a holding position in its path during the lifting movement of the filling frame or can be moved out of this path into a rest position. This ensures that the filling frame in the filling station can be removed upwards from the transfer device, 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 rotating 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, are used for moving the empty mold boxes 6 or for removing the molded mold boxes 7, both roller conveyors are in the loading rich to fold the filling station and the compression station sideways 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 o 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 in the compression station 3, with which the filled sand is compressed in a known manner by a pressure pulse. However, it is within the scope of the invention instead to choose a mechanical or any other compression.
  • 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 moves these stacked parts close to the underside of the sand container 15.
  • 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 out upwards by the jack 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 mold unit is moved o by the rotary table 10 by 180 in the compression station and at the same time the transfer device 13 brings the previously removed from the compacted molding box filling frame 14 in the filling station back while there enters a new, empty flask.
  • 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 stroke movement described at the beginning is repeated in the filling station with the next molding box, which is completed with the filling frame previously 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, molding 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 at a time, always simultaneously a molding box in the filling station and a molding box in the compression station are treated.
  • the molding system according to the invention this means that significantly higher hourly outputs than in the known case.
  • it is characterized by unproblematic and in principle proven construction elements.
