Definitions

  • the invention relates to a molding machine with a sand filling station and a compression station arranged in the transport direction of molding boxes by a transport device after the sand filling station, a vertical center column being arranged between the sand filling station and the compression station, on which a rotary table is mounted, which is used to transport a sand-filled one Form box together with a model plate and a filling frame from the sand filling station to the compaction station and at the same time for transporting an empty filling frame from the compression station to the sand filling station can be rotated by 180 °, as well as with a lifting station in the area of the sand filling station and the compression station.
  • the invention has for its object to provide a molding machine of the type mentioned, which allows the mold boxes to be transported through the molding machine with a minimal outlay in terms of apparatus, with a simple structure and simple, reliable application.
  • the object is achieved in that a horizontally reversibly spaced element is arranged in the region of the turntable, which can be introduced in an intermediate space between an empty molding box and the molding box located in the compression station and is movable with the molding boxes.
  • the molding machine according to the invention is distinguished by a number of considerable advantages.
  • the spacer element which engages in a gap between adjacent mold boxes, it is possible to move the mold boxes by means of a single transport device, which, as seen in the transport direction, is arranged in front of the molding machine. No additional means of transport are required to remove the filled molding boxes from the molding machine. This results in a much simpler construction of both the molding machine and the overall system.
  • the gap between adjacent molding boxes in the area of the molding machine is system-related, since on the one hand no molding box can be arranged in the area of the center column and there on the other hand, a gap occurs in the area of the sand filling station when the model is lowered and rotated in the rotary table in order to transfer a filled molding box into the compression station.
  • the spacer element has a length of two molded boxes. Due to this length dimensioning, there is no disturbance of the cycle spacing of the individual mold boxes, so that undisturbed processing can take place in an entire casting plant.
  • the spacer element is preferably mounted in a central bearing element arranged in the area of the center column.
  • Either the spacer element or the bearing element can be designed such that it can be introduced into the transport path of the molding boxes, for example by means of a pivot lever. In this way it is ensured that when an empty molding box is pushed in, it can be introduced into the molding machine without problems.
  • an additional drive is provided to ensure the reversing return movement of the spacer element, so that it is brought into abutment against the front side of an empty mold box before the push-out cycle of a filled mold box can be.
  • a plurality of spacer elements can be provided, for example it is possible to use spacer rods that are parallel to one another.
  • the molding machine comprises a frame designated 18, which has four vertical columns and two upper and two lower longitudinal beams.
  • a vertical center column 2 is arranged centrally in the frame 18, on which a turntable 3 is rotatably mounted on the lower area and a swivel frame 6 is rotatably mounted on the upper area.
  • the turntable 3 can be rotated clockwise by 180 ° by means of a drive 4, a drive 7 is used for the clockwise rotation of the swivel frame 6 likewise by 180 °.
  • a sand metering device 16 is arranged on the upper area of the frame 18, and there is a compression unit 17 opposite it. The sand metering device 16 and the compression unit 17 are only shown schematically, since they are known from the prior art.
  • Two lifting tables 1a and 1b are arranged on the lower area of the frame 18 and serve to raise and lower a model plate 5a, 5b together with a molding box 10a and a filling frame 8a.
  • I also shows a compressed air tank 19 which is assigned to the compression unit 17.
  • the sand metering device 16 forms a main component of a sand filling station A, while the compression unit 17
  • the main component of a compression station B is (see Fig. I and II).
  • the lifting tables 1a, 1b and the compression unit 17 can be actuated hydraulically.
  • a transport path 20 extends through the molding machine, on which, as shown by the arrow, individual molding boxes 10 can be transported.
  • the drive of the transport path 20 is not shown in FIG. I, it is located on the inlet side of the molding machine.
  • the swivel frame 6 serves to accommodate the filling frames 8a and 8b and to pivot them by 180 °.
  • Support cams 9a, 9b are provided for mounting the filling frame 8 on the swivel frame 6, which can be advanced and retracted by means of a drive (see FIG. III).
  • the support cams 9 When the support cams 9 are retracted, the respective filling frame 8 is released so that, as shown in the left half of FIG. II, it can be placed on a molding box 10a, which in turn rests on a model plate 5a.
  • the lifting table 1a it is now possible to lift the unit consisting of the filling frame 8a, the molding box 10a and the model plate 5a and bring it into the area of the sand metering device 16. After filling, there is a lowering to the state shown in FIG. II, which enables the turntable 3 to pivot this unit by 180 °.
  • the mold boxes 10 are fed by means of the transport track 20.
  • roller track elements 11 are provided, which, for example, by means of a Hydraulic cylinder 12 can be advanced or retracted to allow vertical movement of the mold boxes 10 in the retracted state.
  • a spacer element 13 which is mounted on the frame 18 by means of a bearing element 14, can be pivoted into this gap.
  • the bearing element 14 is in turn attached to a pivot lever 21 which can be pivoted about an axis 22 by means of a hydraulic cylinder 15 (see FIG. III).
  • a displacement force can now be applied to the right-hand molding box 10b through the molding box 10 on the left, whereby the molding box 10 is shifted one position below the sand metering device 16, while the vertical one Molding box 10b is removed from the molding machine and assumes the position of the molding box 10c already in the extension.
  • a hydraulic drive 23 is provided, which is integrated in the bearing element 14.
  • FIG. II shows a state in which a molding box 10a is arranged in the sand filling station A, on which a filling frame 8a is placed. Both lie on a model plate 5a. Sand was already filled in by means of the sand metering device 16, then the lifting table 1 a was moved into its lower end position, while the roller conveyor elements 11 a were advanced so that an empty molding box 10 can be inserted into the molding machine during the next transport step.
  • the following work steps take place simultaneously:
  • the next molding box 10 is pushed on the transport path 20 into the sand filling station A, the finished molding box 10b being simultaneously pushed out of the molding machine by means of the spacer element 13.
  • the turntable 3 rotates through 180 °, around the model plate 5b from the compression station B into the sand filling station A and at the same time the combination of model plate 5a, molding box 10a and filling frame 8a from the sand filling station A to be transferred to compression station B.
  • the swivel frame 6 rotates through 180 ° in order to transfer the filling frame 8b into the sand filling station A.
  • the lifting table 1a moves up, takes over the model plate 5b and the molding box 10 and the filling frame 8b and lifts them under the sanding device 16 so that the required amount of molding sand can be filled.
  • the roller conveyor elements 11a and the support cams 9b move back so that the lifting table 1a can lower the model plate 5b, the molding box 10 and the filling frame 8b onto the turntable 3.
  • the spacer element 13 moves back into its starting position by means of the hydraulic drive 23.
  • the lifting table 1b moves up to raise the model plate 5a, the molding box 10a and the filling frame 8a under the compacting unit 17, so that the molding sand can be compacted.
  • the support cams 9 and the roller conveyor elements 11 advance so that when the filling frame 8 is lowered on the cams 9 and the molding box 10 remains on the roller conveyor elements 11.
  • the model plate 5a is in turn lowered onto the turntable 3. A next work cycle can then be carried out.
