Definitions

  • the invention relates to a unpacking station for molded boxes Casting molds with an ejection unit for the one contained in the molding box Shaped bales.
  • EP 0 878 258 A1 (Article 54 (3) EPC), which has not been previously published Casting system described, which shows a unpacking station for the mold boxes.
  • the unpacking station has an ejection unit in the form of a press plate, which is moved by a press ram.
  • On the opposite side of the Unpacking station is a receptacle for the ejected bale of form arranged.
  • mold-bound molds are made after casting and emptied after cooling.
  • the emptying is done either by shaking the Molding box or in mechanized molding plants by expressing the Mold bales from the mold box.
  • the expression is often done by top down, the bale of form from a considerable height a transport device falls, which is too sensitive with castings Can cause damage.
  • Another way of expressing yourself is in that the shaped bale is pushed out from the bottom up, whereby however, a push-off device is required that the form bales of the ejection plate on a transport device for further transport pushes.
  • the object of the invention is to propose an unpacking station, which they previously considered necessary Reduced work steps and easy to set up and is inexpensive to manufacture.
  • the unpacking station has two superimposed guideways for the one arranged upright during the unpacking process
  • Molding box has that on one side of the molding box the ejection unit in the form of a Press plate provided horizontally movable press die and on the opposite side of the molding box a receiving table for the shaped bale arranged is.
  • a hanging conveyor track above the recording table arranged that the casting from standing out pulls out the bale of mold that is pushed out.
  • the two superimposed guideways serve on the one hand, through the upright molding box to run the unpacking station and at the same time an abutment to form when the bale of form from the side the mold frame of the mold is pushed out.
  • the Casting can then be done easily with a hanging The transport path is pulled out of the bale and be transported away.
  • the mold can be arranged vertically, whereby this can be done either by lying down Cast mold brought up on the transport line via a Turning device placed vertically and then the unpacking station is fed. After unpacking the mold is then in a vertical position fed to and through this second turning device transferred back to the horizontal position, which is advantageous for molding the mold as well as for core insertion is.
  • the turning device with four at an angle of 90-degree guideways, so that the molded boxes are inserted horizontally into the unpacking station can be and pushed out of this standing to become. After unpacking the molding box turned back again.
  • Such a device can also be integrated into an unpacking station so that also unpacked cast molded boxes and again be transferred to a lying position after unpacking can.
  • Fig. 1 shows an unpacking station 1 in a transport line 2, is turned on.
  • the two mold box halves 3.4 molds 5, are from the right seen in the drawing the unpacking station 1 standing fed.
  • the molding boxes 3, 4 on a Transport line 2 arranged upright, consisting of two U-beams 6, which has transport rollers on the inside 7, have.
  • the removal of the molds 5 done in a horizontal manner from the unpacking station 1 likewise via a transport line 2, which accordingly the first transport line is formed, wherein however, the U-beams 6 are at a greater distance from one another exhibit.
  • the unpacking station 1 has a slewing ring 8 on the two opposite guideways 9 wears.
  • These guideways 9 also point Transport rollers 10 on the mold 5 to the corresponding Support approaches 11.
  • the construction of these guideways 9 goes in particular from FIGS. 2 and 3 forth.
  • a press ram 12 On one side of the unpacking station 1 is a press ram 12 provided with a press plate 13 and on the opposite side, a recording table 14 for the inclusion of the mold bale 15 of the casting mold 5.
  • Fig. 1 is schematic Unpacking station shown in more detail shown.
  • the unpacking station 1 has a frame 17, wherein the turntable 8 on rollers 18 carried by the frame rests.
  • a drive motor 19 serves to turn the turntable.
  • the receiving table 14 In the amount of The opening of the two mold box halves 3, 4 is the receiving table 14 arranged, which is slidable on rollers 21 is stored. A piston-cylinder unit is used for the displacement 22. This shift of the table is required when the molding box is in the unpacking station should be turned so that it is standing unpacked or, if necessary, lying back out of the unpacking station can be brought out.
  • the castings are removed by means of a hanging conveyor track 16, which takes the castings 23 and separates them from the molding sand 24.
  • an unpacking station 1 which is switched on in a transport line 2, in which the molded boxes are poured horizontally, unpacked standing and transported further lying down.
  • the unpacking station 1 are each a turning device 25,26 upstream or downstream, these turning devices are each provided with four guideways 27, so that the molds 5 in each of the turning devices from lying to standing or from standing can be transferred to the lying position.
  • the transport of the molding boxes through the turning devices 25.26 can only be done by pushing the Molded boxes 3.4 are accomplished.
  • the structure of the Unpacking station is shown in detail in Fig. 5, in contrast to the unpacking station 1 to 3, the guideways 9 rigid with the frame 28 of the unpacking station 1 are connected.
  • the order the ejection unit 12, 13, 20 is the same as in FIGS 1 to 3 are shown. There is a difference in the formation of the recording table 14, which is in contrast here to the embodiment of FIGS. 1 to 3, can be rigid.
