    57 Zur Herstellung von horizontal geteilten kastenlosen Sandblock-Gießformen dient eine Formanlage, die aus einer Vakuu-Formschießmaschine 1, einer Vorrats-, Gieß- und Kühlstrecke 18 mit Umlaststation 19. Gießstation 20, Auspackstation 21 und Paletten-Rücklaufstrecke 22 besteht. Die Vakuum-Formschießmaschine 1 ist mit einer Modellplatten-Wechseleinrichtung 16 versehen und als Einstation-Formmaschine ausgebildet, auf der Unter- und Oberballen der Gießform im Wechsel hergestellt werden. Sie hat einen maschinenfesten Formkasten, der vor dem Ausfahren jedes Ballens aus der Formstation gestrippt wird. Das ermöglicht die Zuordnung zu einer Kernsetzstation 17 mit mehreren Ballenstandplätzen ohne zusätzliche Maschinen-Formkästen.

    The invention relates to the foundry industry, namely to the manufacture of non-sinterless casting molds with a horizontal connector line.
    The aim of the invention is to simplify the molding line.
    FIG. 1 shows a vacuum molding machine, side view; of figs. 2 is a diagram of the molding machine, top view.
    The vacuum molding machine 1 has four guide columns 2, along which the support frame 3 of the hopper 4 with the molding mass and the support frame 5 for the flask 6 can be vertically moved by the cylinders. The support frame 5 is equipped with a rotary device 7 in order to provide the possibility of turning the machine flask around horizontal axis 8. J A molding table 10 is rigidly fixed on the base plate 9, on the surface of which are centered the elements 11 for the pallet 12 and hollow sub-model plates 13. The molding table is surrounded by two The vertically movable sections 1A and 15 of the roller table, by means of which the model plates 13 and the pallet 12 are supplied and discharged in different directions.
    The molding line refers to position 16 (Fig. 2) of the changing of model plates, on which alternately submodel plates with models of the lower and upper parts of the mold are brought to the molding position, and the position 17 of the rods, which is made in the form of a rotary table, however it can be made in the form of a carriage line.
    The molding line contains an accumulation, casting and cooling section 18 with the positions of the withdrawal 19, the pouring 20 and the unloading 21, to which the return section 22 and the supply of the pallets 12, freed from the flask molds, are attached to the molding vacuum machine 1.
    The molding station. Through connecting fittings 23 is connected to sources 24 of vacuum or compressed air, which by means of valves having control system 25 are in working connection with the hollow space of the model plate 13, which is sealed with

    seals 13a with respect to the molding table 10.
    For the manufacture of casting molds, the sub-model plate 13 with the model for the lower part of the mold is lowered onto the table 10, guided by the centering pins, and its hollow space is tightly connected to the connecting fitting 23 on the molding table to create a vacuum or to supply compressed air. Then, the supporting frames 3 and 5 are lowered by means of the control system 25 until the flask fits snugly with the seals 13a to the submode plate 13, after which the supporting grill 8 is immersed in the flask 6 by the size specified in advance using the model height. The grate then opens and, using valves 26 controlled by the device 23, an abrupt vacuum is created in the molding table 10, which is transmitted through the vents of the hollow submodel plate 13 and the model to the mold 6, which results in suction of the molding mixture from the hopper 4 and its compaction.
    The mixture can be additionally compacted by means of a pressing grid 8 (with closed holes) or by the pneumatic method.
    Then the carrier frame 3 with the hopper 4, the carrier frame 5 with the flask 6 containing the bottom half-form, are raised until the necessary free space is obtained for turning the flask 6. The finished half-form is accompanied by supplying the compressed air into the hollow space of the submodel plates 13.
    After the sub-model plate 13 is removed from the molding position of the flask 6, the rotary device 7 rotates 180 ° and the transport pallet 12 with 5 using the section 15 of the roller table, which for this purpose is raised relative to section 14, is transferred to the molding table and precisely positioned by the centering pins 11. The carrier frame 5 with the flask 6 is then lowered and the molded lower part of the mold is rotated onto the pallet 12. By further lowering the carrier frame 5 to the position represented by dashed lines in the right half in FIG. 1, the flask is folded from the bottom of the mold.
    After that, the section 15 of the roller table rises and the lower part of the form on

    the pallet 12, raised from the molding table 10, is displayed at the rod setting position 17. Thereafter, the carrier frame 5 with the flask 6 rises again to the baseline.
    Position 17 for the installation of rods has several established places for the lower parts of the molds. The workflow is repeated until all the installation places are clamped by the lower parts of the molds.
    For making the bottom

    the upper parts of the molds, the model plate 13 with the model of the top is fed to the upper mold of the mold and, similarly to the lower model tooling, the guides of the mold are made of the mold top. Flask 6 with top half-form does not rotate, it is installed on the bottom-fitted half-mold, 2o transferred on the pallet 12 from the position 17 of the installation of the rods to the molding position and centered in it. In case of small sizes of the mold parts, they are equipped with an op-vertical stand, a stationary work table and a bunker with a subpress grid, which is fixed with the possibility of vertical movement along the guide posts, the mounting position of the rods, the pouring and cooling section and the pallet return section, which is different.
    molding cycle. At the end of the production of a series of molds, such a number of upper molds is formed which corresponds to the number of lower mold portions that are in the installation position of the rods. Operational operations occur in the sequence specified by the control device 25.

    In order to avoid the lower part of the mold, it is advisable to pull the mold 6 from the upper part of the mold upwards to avoid scraping the molding material from the side surfaces of the lower part of the mold during the continuous immersion of the flask. For the bucket, the hopper with the molding compound is lowered with the help of the supporting frame until it is closed and its grill 8 does not touch the upper side of the upper part of the mold, which is laid on the lower part of the mold. When the grille 8 is pressed, the supporting frame 5 moves upwards and the flask 6 is clipped.
