Definitions

  • the invention relates to a jacket for supporting castless forms during casting.
  • Casting molds are subjected to pressure from inside to outside when pouring through the liquid metal, in both the horizontal and vertical directions.
  • the horizontal pressure forces are absorbed by the molding box, while the vertical buoyancy forces are absorbed by clamping the mold box halves or by weighting weights that are placed on the top box.
  • Such devices are known, one part of which acts as a weighting iron and the other part of which is pressed against the side surfaces. Such facilities are complicated and expensive. In addition, the weight plate and the actuation mechanism for the side plates interfere with the casting.
  • a further disadvantage with known systems is the risk that when the device is placed on the boxless mold by means of side joints, the upper part of the mold is displaced against the lower part, so that "offset" occurs on the casting and waste is produced.
  • the present invention has set itself the task of eliminating the disadvantages listed and creating a simple device that absorbs both the vertical and horizontal casting pressure, ensures an offset-free placement and can be easily cleaned automatically.
  • Fig. 1 the top view of a boxless mold with a support device, which is referred to as a jacket, is shown.
  • Fig. 2 a cross section of the form with jacket and trolley is shown.
  • the boxless mold consisting of the lower mold part 1 and the upper mold part 2, is transported on a trolley 3.
  • the jacket consists of a heavy frame 5 and four pressure plates 6.
  • the pressure plates 6 are connected to the frame 5 in an area delimited by the screws 8 such that they can be moved in height by inclined surfaces 10.
  • the pressure plates 6 each have at least two feet 7 which are supported on the carriage 3.
  • the arms 4 of the translation device lift the jacket on the frame 5 from the already cast castless shape, the pressure plates initially not changing their height by the upward movement of the frame 5, so that due to the inclined contact plane 10 and the screws 8 movable in a vertical slot, one horizontal movement away from the boxless form, whereby a gap 9 is formed on all sides.
  • the jacket is put on in the reverse order:
  • the translator carries the jacket on the frame 5 with the arms 4 and lowers it with a spacing gap 9 over the mold until the pressure plates 6 touch the carriage 3 with their feet 7.
  • the frame 6 is moved even further downward, the pressure plates 6 being pressed uniformly against the mold on all sides by the inclined contact surfaces 10. Due to the exact parallel movement of the pressure plates, displacement (misalignment) between the upper and lower bales (1, 2) is impossible.
  • the top bale is held against the vertical casting pressure by the force-fitting pressing of the pressure plates, so that the entire top of the mold is kept free for casting.
