Definitions

  • the present invention relates to a low-pressure mold casting device according to the preamble of claim 1.
  • Such a casting device is described in CH-PS 637 856.
  • This has a rotatably mounted column arranged on the side of the furnace, on which a support frame sits in a rotationally fixed manner.
  • a bearing head for a carrying device is guided on the supporting frame so as to be displaceable in the vertical direction.
  • This has support members on which the mold parts are arranged and which are mounted so as to be displaceable and pivotable.
  • a disadvantage of the known device is that large openings have to be provided or made in the foundry floor so that parts of the device can be lowered into them, so that the footprint of the device for the operating personnel is approximately at the same level as the foundry floor.
  • the opening of such openings is associated with great effort, in particular when the device is installed in already existing buildings. This can also reduce the load capacity of the foundry floor.
  • a turntable On the cross member of a portal-shaped support frame, the supports of which are provided outside the pivoting range of the support device, a turntable is arranged, about the axis of rotation of which the support device for the mold parts can be pivoted.
  • the turntable is located above the furnace and any other workstations, which allows the columns to be placed on the foundry floor; no space is required on, in or under the floor for a column to be pivoted.
  • the forces are distributed in the foundry floor, which leads to smaller surface loads.
  • the entire area between the columns and below the turntable is free for setting up the furnace or other work stations. This allows a compact design, whereby the axis of rotation can also run through the furnace or another work station.
  • the low-pressure mold casting device shown in the figures has a melting furnace 10, the supporting frame 12 of which is arranged lying on the foundry floor 14.
  • the melting furnace 10 is of a known type and has a riser pipe 18 opening into a pouring mouth 16 arranged on the melting furnace 10 (see FIG. 3).
  • a portal-shaped support frame 20 has four columns 22, 22 ', which are arranged approximately at the corners of a square floor plan, two columns 22 are supported laterally of the melting furnace 10 on its support frame 12 and the other two columns 22' attached to the foundry floor 14 are.
  • Each column 22 is connected at the upper end by a side member 24 with the corresponding column 22 '.
  • the two side members 24 carry two cross members 26 which run at right angles to the side members 24 and are spaced apart in the direction of the side members 24 and on which a turntable 28 is arranged approximately in the center.
  • the axis of rotation 30 of the rotary table 28, indicated by dash-dotted lines, extends in the vertical direction and to the side of the melting furnace 10.
  • the rotary table 28 is driven by an electric motor 34 via an indexing gear 32.
  • a two-armed arm 36 is arranged on the turntable 28, which at both ends, from the axis of rotation 30 equally far away, each carries a carrying device 38 for the molds 41 consisting of two mold parts 40.
  • Each support device 38 has a vertical support profile 42 which is guided on the arm 36 so as to be displaceable in the vertical direction. 1 and 2 in the horizontal and in the radial direction with respect to the axis of rotation 30 running rail profile 44 is pivotally mounted at the lower end region of the support profile 42 about a horizontal axis and perpendicular to the longitudinal extension of the rail profile 44 pivot axis 46. On the outer end region of the rail profile 44, seen in the radial direction, a support element 48 protruding downward is fastened thereon, on which a support 50 is rotatably mounted about a pivot axis 52 running parallel to the pivot axis 46.
  • a slide 54 which also projects downward, is guided on the rail profile 44 so as to be displaceable in the direction of arrow A.
  • a carrier 50 is also mounted on the carriage 54 so as to be pivotable about a further pivot axis 52 running parallel to the pivot axis 46.
  • the two carriers 50 are from the parallel to the rail profile 44 and aligned rest position, in which the free ends of the carrier 50 are directed towards each other, by 90 ° in a dash-dotted and indicated by 50 'pivotable position in which the carrier 50 is at right angles protrude from the rail profile 44.
  • the mold parts 40 are fastened to the free ends of the carriers 50. When the carrier 50 is pivoted in the rest position and the carriage 54 is in the closed position, the mold parts 40 lie against one another, when the carriage 54 is in the open position, the mold parts 40 are spaced apart.
  • the parting plane 56 between the two mold parts 40 is a vertical plane and extends at right angles to the longitudinal extent of the rail profile 44, which is radial in relation to the axis of rotation 30 when the mold 41 is filled Direction runs.
  • One ejection element 58 is provided in each of the carriers 50 in order to eject the cast parts from the mold parts 40 which are spaced apart from one another.
  • the support device 38 shown on the left is in the pouring position above the melting furnace 10 and the other support device 38 is above a size bath 60 diametrically opposite the melting furnace 10 with respect to the axis of rotation 30. This is on the foundry floor 14.
  • a removal station 62 is provided, as seen in a clockwise direction U, offset by 90 °.
  • This has a conveyor 64 driven in the conveying direction F for the cast parts, which are ejected from the mold parts 40 by means of the ejection elements 58.
  • a blasting device 66 for sandblasting the mold parts 40 is also assigned to the removal station 62.
  • the removal station 62 is diametrically opposite a core insertion station indicated by the arrow 68.
  • the mode of operation of the low-pressure mold casting device shown in FIGS. 1 and 2 will now be explained in more detail with reference to FIGS. 3 to 7.
  • the one of the two carrying devices 38 is tracked in the course of a working cycle.
  • the working cycles of the two carrying devices 38 are identical but shifted by half a cycle.
  • the carrying device 38 is in the pouring position above the melting furnace 10, the mold parts 40 lying against one another being deposited on the pouring mouth 16 of the riser pipe 18.
  • the casting compound is conveyed through the riser pipe 18 and the pouring mouth 16 into the mold 41.
  • the mold 41 is lifted from the melting furnace 10 by lifting the carrying device 38 and brought to the removal station 62 by rotating the turntable 28 in the direction of the arrow U by 90 °.
  • the mold parts 40 are separated from one another by moving the slide 54 from the closed position into the open position along the rail profile 44, as shown in FIG. 4.
  • the ejection elements 58 By actuating the ejection elements 58, the cast parts are ejected from the mold parts 40, which fall onto the conveyor 64 which is only indicated schematically.
  • the carrying device 38 comes to lie over the size bath 60 (FIG. 5) and is lowered.
  • the carriers 50 are pivoted about the pivot axis 52 into the pivot position 50 ', whereby the mold parts 40 are immersed in the size bath 60, avoiding the formation of air cushions in the recesses of the mold parts 40.
  • the surfaces of the mold parts 40 facing the parting plane 56 in the sizing bath 60 are directed downward.
  • the carrying device 38 is then raised again and the supports 50 are pivoted back into the rest position aligned with one another.
  • the carrying device 38 By turning the turntable 28 again by 90 °, the carrying device 38 reaches the core insertion station 68.
  • the rail profile 44 is pivoted 90 ° about the pivot axis 46 in a counterclockwise direction into a vertical position, whereby the now horizontal mold parts 40 with respect to the axis of rotation 30, seen in the radial direction, lie outside the rail profile 40.
  • This enables problem-free insertion of the cores by operating personnel or an automatic core insertion machine (not shown).
  • the mold 41 is closed by moving the slide 54 in the direction of arrow A into the closed position towards the top (FIG. 6).
  • the rail profile 44 is then pivoted 90 ° clockwise about the pivot axis 46. After a further rotation in the direction of arrow U of the turntable by 90 ° and the mold 41 being lowered onto the pouring mouth 16 of the melting furnace 10, the working cycle is ended.
