Definitions

  • the method and the device relate to molding machines in which the upper box and lower box are molded in a machine in a mold strand.
  • the model with model carrier is alternately swung out and in between the successive impressions of the upper and lower case by means of a turnstile (shuttle) in order to then continue to cycle the finished case.
  • a turnstile shttle
  • the function of the feed and the necessary turning of the turnstile (driving the shuttle) each form individual processes (work processes).
  • US-A-5,040,587 describes a rotating changer for model and model plate carrier, in particular a turntable.
  • a linear transfer device for the filling frame is arranged above the rotating changer. This combination is referred to as advantageous in the prior art. (see US-A-5 040 587, column 2, 50).
  • the object of the invention is to increase the speed of the machine unit. This is achieved with claim 1 or claim 14.
  • Thrust and model transport are carried out as a sand-filled unit in one function.
  • a single lowering stroke or shuttle train is no longer available.
  • a filling process and a molding process and the forwarding of a unit and the backward conveying of the upper and lower parts of this unit are advantageously interleaved with one another in such a way that cycle times can be saved.
  • the conveying processes take place in a vertically offset back and forth circulation.
  • the interleaving means "pipelining", so that individual work processes which were previously time-consuming in the prior art are now interleaved in such a way that they run in parallel without a collision.
  • the model carrier is lifted vertically into the filling station (station I).
  • the molding box and filling frame are filled with sand.
  • the second molding box is pre-compressed in the compression station (Station II) and then finally compressed and the model is lowered vertically.
  • the entire unit is clocked further from the push cylinder of the molding section into the pressing and compression station (station II).
  • the model with model carrier is carried.
  • the compression station e.g. airflow pre-compression and pressing.
  • the lowered model and the empty filling frame are returned from the compression station II to the filling device (station I) during the transport of the (other) box and model carrier (to station II).
  • the device for the return transport of the model carrier and the filling frame from the compression station takes place in a straight line parallel to the box conveyor or via a rotating device. Both devices run in cycle time.
  • An integrated model change is possible synchronously, but it is also possible to exchange the top box model and bottom box model alternately in the form cycle (claim 13).
  • the molding box is fed as a unit to the molding station, namely in the direction of the conveyor line v.
  • the conveyor line runs from right to left in Figure 1 between FoS and FüS.
  • Two complete mold boxes 12a, 12b can be seen, a schematically indicated third mold box 12c can be seen on the right edge of the picture, a "molded" fourth box in FIG. 2a or 3b on the left edge of the picture.
  • the mold boxes are conveyed in the conveying cycle in the direction of arrow v, which runs in the x direction.
  • a circuit X, Y can be seen above and below the conveyor line v.
  • the circuit consists of a pair of frames (frame-shaped model carriers or filling frames).
  • a pair of filling frames 11a, 11b circulate above the station conveyor line v.
  • a pair of models 14a, 14b with respective model carrier frames 13a, 13b circulate below them.
  • the circulation movements are indicated by arrows X, Y, they run in the vertical direction, so that one filling frame 11a is moved from the filling station to the molding station and the other filling frame 11b of the pair from the molding station to the filling station.
  • FIG. 1 it can be seen how a unit consisting of filling frame 11a, molding box 12a and model carrier 13a with inserted model 14a (not visible) is clocked from the filling station (after filling there with molding sand) in the direction of the conveying line to the molding station.
  • the conveying cycle corresponds to the length of a molded box 12a.
  • the molded molding box is conveyed out of the molding station II after it has previously been separated from the filling frame 11b and model 14b on the model carrier 13b.
  • the separate frames 11b, 13b are conveyed back during the advance of the mentioned unit, so that they come to rest again in the filling station and are ready for a new assembly with the molding box 12c indicated in FIG.
  • the upward movement of the lifting tables 2b, 2a and their downward movement can be part of the upper and lower circuits X, Y with respect to the respective interchanging frames.
  • FIG. 1 The principle of back-and-forth transport explained in FIG. 1 with a vertical offset along a first circuit X above a conveyor line of mold boxes and the back-and-forth transport of two models in or below the conveyor line of the mold boxes is to be based on instantaneous recordings in four situations are illustrated.
  • the center of the sand mold compaction device with filling station shown in FIGS. 3a, 3b, 3c and 3d is identical to the section shown in FIG .
  • a feed line and a discharge line of the molding boxes 12 can be clearly seen in FIG. 3.
  • the molding box 12c waiting in front of the filling station can also be seen in FIG. 3b, as does the molding box 12d previously conveyed out (molded and filled with compacted sand).
  • FIG. 3d shows the state that is present after the left filling frame 11b and the left model 14b have been returned to the sand filling station I.
  • the three elements to be assembled into a "package" are still separate, the molding box 12c in the conveyor line, the model 14b below and above the conveyor line of the filling frame 11b.
  • the lifting table or cylinder 2a By moving the lifting table or cylinder 2a upwards, the three elements are successively brought together and moved together against the lower edge of the sand filling station.
  • the model 13b Before the model 13b enters the molding box 12c or while it is being transported back, it can be cleaned, for example by blowing it off. It can also be sprayed on afterwards.
  • Figure 3b shows the compression by the press head (multi-punch press head) 20.
  • the compression can be done with or without pre-compression.
  • the pivoting of a roller conveyor 40b into station II, which has not yet been drawn in here, begins, which, when the molded package is lowered, leads to the molded mold box 12b being placed gently on it.
  • the package filled with sand is lowered from its upper limit position to such an extent that it is without Contact with the left filling frame 11b to be conveyed back can be conveyed forward together in the molding box conveying direction x.
  • a roller conveyor 50b is also swiveled in in order to enable the aforementioned return of the left filling frame 11b.
  • the movement is then repeated in order to be able to take cyclical impressions at high speed.
  • the two models which are alternately filled and compressed with sand, can be the same; they can also consist of an upper box and lower box model.
  • model carrier with model which is moved back and forth below the conveyor line, its vertical offset with respect to the mold box conveyed in the conveying direction being dimensioned at least such that the model has been led out of the mold box and its top point below the lower level of the mold box comes to lie.
  • the feed movement which the mold boxes 12a, 12b carry out within the two-station machines I and II need not lie in the same plane as the plane for feeding empty ones Mold boxes and the level of removal of "molded mold boxes". A slight to clear spacing of these conveyor levels can be selected in order to adapt the machine to certain transport situations at the installation site.
  • FIG. 2a shows a snapshot that is comparable to FIG. 3c; for this snapshot, FIG. 2b shows a front view of both the swiveled-in roller conveyor 40b in station II and the swiveled-in roller conveyor 40a in station I.
  • the lower roller conveyors 40a, 40b which are located approximately on the same level, show the roller conveyors 50a and 50b to be swiveled in, which enable the upper filling frame to be conveyed back.
  • the roller tracks are attached to a longer lever arm so that the roller track is already activated or deactivated by a slight swivel angle of the lever.
  • roller conveyor 40a, 40b two further roller conveyors 60b, 60a are provided, which can also be designed to be pivotable in; they serve to return the model carrier with model plate from station II back to station I.
