Definitions

  • the invention relates to a device for changing the complete firing hood and / or the nozzle plate and for removing the residual sand from the firing hood on core and mask shooting machines.
  • the replacement of the firing hood or the nozzle plate is largely carried out in the machine above the tool carrier. This will contaminate the machine. Accessibility is not optimal and only hoists, forklifts etc. can be used as aids. The time required is very large, the machine must be shut down for a long time.
  • the object of the invention is to improve the workflow on a core and mask shooting machine with regard to changing the firing hood and / or the nozzle plate in a substantial manner while simultaneously emptying the residual sand from the firing hood.
  • the device consists of a boom which can be pivoted about a vertical axis, with a built-up lifting unit with two bearing points and a mechanical reversing gear with reversing coupling for receiving and rotating the shot cap connected to the nozzle plate around a theoretical horizontal axis.
  • the device according to the invention for the rapid replacement of the firing hood and / or nozzle plate is particularly suitable in connection with a modern core and mask shooting machine which is equipped with a quick tool changing device. The remaining sand from the change is removed from the firing hood before the nozzle plate is released.
  • the level of sand in the magazine is stopped by a level probe in the firing unit before the changing process or the shooting unit is shot empty by an additional firing process.
  • the changing device is swung in below the extended shooting unit and the lifting unit is raised to its end position. Then there is a decoupling with the firing hood and nozzle plate connected by the firing unit.
  • the lifting unit with the firing hood moves downwards and swivels around a horizontal axis to empty the remaining sand and then be turned back and raised again.
  • the shooting hood is attached to the shooting unit, the nozzle plate is separated from the shooting hood and the nozzle plate is replaced by the same device.
  • the changing device 1 consists of a boom 4 pivotable about a vertical axis 14 with the pneumatically or hydraulically actuated lifting unit or the lifting station 5, which is equipped with two bearing points 6 and a reversing gear 7 with a reversing coupling 8. Parallel to changing the tools or the end of the shift, the shooting unit 9 is pivoted out of the machine or moved out, as described in DE-PS 3 148 461.
  • the device 1 is mechanically or manually swung in and extended below the opened shooting unit 9.
  • the nozzle plate 2 is equipped with two bearing journals 11 and a coupling piece 12. When opening or when the end position of the lifting unit 5 is reached, the two bearing pins 11 lie in the two bearing points 6 and the two coupling pieces 8, 12 move parallel to one another.
  • the lifting device 5 moves off with the shooting hood 10 lying thereon.
  • the reversing gear 7 can now turn the complete firing hood 10 about a horizontal axis 15, so that the remaining sand therein can be emptied into the container 3 (FIGS. 1, 3 and 4).
  • the lifting unit 5 is raised. Then the shooting hood 10 can be mechanically fastened again to the shooting unit 9 and then the nozzle plate 2 can be replaced. The same device 1 is used for this, only the reversing gear 7 is inactive.
  • the alternative replacement also applies to changing the nozzle plate 2.
  • the mechanical connections between the nozzle plate 2 and the firing hood 10 are released, the lifting unit 5 with the nozzle plate 2 lying thereon is moved down. After the device 1 has been pivoted away horizontally, away from the firing unit 9, access to the nozzle plate 2 is ensured.
  • the nozzle plate 2 can be exchanged for a new one (FIGS. 2 and 6).
