  • a manipulator 46 same structure, see in particular Fig. 1.
  • the recesses are designed such that the two manipulators 46 about the axis of rotation 20 can rotate relative to each other from about 80 ° to about 280 °.
  • a rotating union 48 for the connection of the control device 34 coming control and feed lines with the manipulators 46.
  • the part of the rotating union fixed to the turntable 48 with the manipulator arranged on the inner support tube 40 ' 66 rigid lines can be used, whereas for connection flexible lines are to be provided with the other manipulator, which the mutually different rotational position can take up.
  • Carrying profile 50 of the manipulator 46 running in the vertical direction in the vertical Direction can be raised and lowered.
  • a rail profile 52 At the lower end of the support profile 50 is a rail profile 52 about an axis of rotation 20 in tangential direction axis 54 rotatably mounted.
  • the rail profile 52 is by means of a corresponding drive about the axis 54 from one running in the horizontal direction to one in the vertical direction current position and swiveling back again.
  • a cantilever-like support member 56 is fixed and on the other hand a carriage 58 to and from the support member 56 slidably mounted away.
  • the distance between the axes 54 from the axis of rotation 20 is the same size and in 1 labeled R.
  • the manipulators 46 can thus along a turning circle 68 - see FIG. 2 - about the axis of rotation 20 to work stations 70 are moved. It goes without saying that these workstations 70 along the rotating circle 68 in the circumferential direction one behind the other are.
  • FIG. 1 is a core insertion station 72 on the right and a casting station on the left 74 shown. As can be seen from Fig. 2, these are two Stations 72, 74 at an angle of approximately 160 ° with respect to the axis of rotation 20 arranged to each other.
  • the casting station 74 has a melting furnace 76 known type with one arranged in a above the melting furnace 76 Pipe 80 opening riser pipe 80.
  • the casting station 74 Seen in the direction of rotation D, the casting station 74 is followed by a removal station 82 with a conveyor 84 for those ejected from the mold 66 Castings and then a sizing station 86 with a sizing bath 88.
  • the removal station 82 is to the casting station 74 and the finishing station 86 to the core insertion station 72 at an angle of approximately 80 °.
  • This has one at right angles to one Radial 90 'running rails 92 movable beam device 94 for jet cleaning the mold parts 64, 64 '.
  • Fig. 2 is the jet device 94 in the working position. She will head out of this the arrow A is moved to a rest position, is for a possible Change of mold access created.
  • the mold change can either by hand or by means of a mold changing device, not shown respectively.

  • the rail profile 52 is in a radial position.
  • the manipulator 46 is now rotated and lowered over the size bath 88.
  • the carriage 58 is in the open position Carrier 62 pivoted about the pivot axes 60 by 90 ° into a position in which they point away from the rail profile 52 at a right angle, whereby the Mold parts 64, 64 'while avoiding the formation of air cushions on the recesses immerse the mold parts 64, 64 'in the sizing bath 88, such as this shows Fig. 6.
  • the manipulator 46 becomes again raised and the carriers 62 are in the aligned working position swiveled back.
  • the two manipulators 46 are independent of one another about the axis of rotation 20 are movable, they can be simultaneously at the core insertion station and are at the casting station 74.
  • the operations in these two Workstations 70 take significantly longer time than purging the castings in the removal station 82 and the immersion of the mold parts 64, 64 'in the finishing bath 88.
  • the other manipulator 46 can follow End the pouring process from the pouring station 74 to the removal station 82 and then move to the finishing station 86.
  • This manipulator 46 can then be rotated into the core loading station 72 when the other manipulator 46 leave the core insertion station 72 in the direction of the casting station 74 Has.
  • the mold parts are after a certain number of work cycles 64, 64 'to be cleaned by irradiation, for example with brass shot.
  • the manipulator 46 in question is brought into the service station 90 rotated.
  • the mold parts 64, 64 'by means of the jet device 94 are treated, the production goes by means of the other manipulator 46 by turning in and against the direction of rotation D.
  • this manipulator 46 of the core insertion station 72 against the direction of rotation D to the casting station 74 moved and lowered onto the pouring mouth 78.
