Definitions

  • This invention relates to a method for inserting cores into casting moulds of the type consisting of successively produced uniform mould parts which in time with their production are slid together so as to form a horizontal pile mould having one or more casting cavities at each joint in the mould, and where the cores are inserted into the freely exposed casting cavity in the last mould part added to the pile mould.
  • the method according to the invention is characterised in that the cores are inserted by means of a core carrier provided with core holders corresponding to the core receiving guides of the casting cavity, the said core carrier being moved in two stages, viz, first transversely to the direction in which the mould parts are slid together, until the cores lie direct in line with the core receiving guides, and next parallel to the direction in which the moulds are slid together for the purpose of inserting the cores into the receiving guides of the moulds, in which position the cores are released from the holders. Then the core carrier may be returned to its starting position in which it lies outside the path along which the mould parts are slid together and advanced.
  • the insertion of the cores will only require a minimum of space in front of the freely exposed casting cavity in the pile mould, and furthermore it is possible to ensure an extremely accurate placing of the cores in the receiving guides of the mould parts, so that there will be no risk of damage to the mould part.
  • a similar precision will not be required in the case of the possible manual placing of the cores in the holders of the core carrier because the core carrier may in itself be very formstable and because its holders may be so arranged that the cores will so to speak automatically be brought into the correct position.
  • this core insertion unit comprises a core carrier in the form of a plate provided with core holders, said plate being secured to a shaft which is longitudinally displaceable and rotatable around its axis.
  • the core carrier may be controlled manually, e.g. by an operator who also places the cores in the holders of the core carrier, but it is preferred that the core carrier is arranged for being moved in time with the production and sliding together of the mould parts, preferably by means of hydraulic or pneumatic driving units. This entails that under certain circumstances manual labour may be saved, and that also a saving of time may be attained resulting in an increase of the production capacity.
  • the holders of the core carrier may be formed by sockets in which the cores can be held by a vacuum which is eliminated or substituted by a positive pressure after the cores have been inserted into the core receiving guides of the mould parts.
  • FIG. 1 being a side elevation of the core insertion unit with a number of mould parts or briquetted bodies indicated in dotted and dot-and-dash lines,
  • FIG. 2 a plan view of the core insertion unit shown in FIG. 1, and
  • FIG. 3 a section on line IIIIII in FIG. 2.
  • the dot-and-dash lines indicate a number of mould parts or briquetted bodies 1a, 1b, 1c, 1d and 1e which by being slid together in the direction of the arrow shown are made to form a horizontally disposed pile mould, and 1 indicates still another mould part which has just been produced, e.g. by pressing in a forming chamber between two opposed pattern boards, and which is to be connected to the mould part 16 by a movement in the direction of the arrow 2, while at the same time the whole composite mould is displaced in the same direction so that the mould part It will take up the place of the mould part 1e, etc.
  • the mould comprises one or more casting cavities which for the sake of perspicuity are not shown in the drawing.
  • each of the core holders 6 is supposed to comprise a socket formed in the plate 7 and having one or more bottom apertures 8 which through communication lines, not shown, are in communication with a vacuum source, so that the cores 5 can be retained by suction in the holders 6.
  • the plate 7 is carried interchangeably, e.g. by means of bolts 9, by an arm 10 secured to a shaft 11 which is parallel to the direction of advance of the pile mould.
  • the shaft 11 is accommodated so as to be longitudinally displaceable and rotatable in a pair of bearings 12 on a bracket or a support 13 which must be supposed to be rigidly secured to the machine, not shown, in which the production of the mould parts v1 is carried out.
  • the right hand end of the shaft 11 is through a piston rod 14 connected to a hydraulic or pneumatic cylinder 15 carried by a supporting plate 16.
  • Twoother driving units 17 and 18 of the same type enable the shaft 11 to be turned backwards and forwards, each of these driving units being through a piston rod 19 connected to an arm 21 on a sleeve 20 which surrounds the shaft 11 and is so connected to the shaft 11, e.g. by means of sliding keys, that the shaft is carried along by a turning of the sleeves, but is freely displaceable in the latter.
  • the core carrier 7 In the position shown in the drawing the core carrier 7 is in line with the pile mould, so that the cores 5 lie direct in line with, i.e. axially opposite the core receiving guides, not shown, in the casting cavity of the mould part 1e. In this position the cores 5 are still retained in the holders 6 by a vacuum. From this position the core carrier 7 is displaced in the direction of the arrow 2 by being actuated by the driving unit 15, until the cores 5 have been placed in their final position in the mould part 1e.
  • control of the driving units 15, 17, and 18 may by means of an appropriate mechanism, not shown, be performed in time with the production and sliding together of the mould parts, and the insertion of the cores 5 into the core carrier 7 may also be performed mechanically.
  • the two driving untis 17 and 18 may for example be substituted by a single, double-acting driving unit, and other driving units than hydraulic or pneumatic cylinders, may also be conceivable.
  • the insertion of the cores may be performed by means of a core carrier 7, the transverse movement of which is a straight displacement instead of an angular displacement as shown in the drawing.
  • a unit for inserting cores into casting moulds consisting of successively produced uniform mould parts which in time with their production are slid together so as to form a horizontally disposed pile mould having one or more casting cavities with core receiving guides at each joint in the mould, comprising a core carrier having core holders corresponding to the core receiving guides of the casting cavity, means .for moving said core carrier in two stages, first transversely to the direction in which the mould parts are slid together until the cores lie direct in line with the core receiving guides, and next parallel to the direction in which the mould parts are slid together for the insertion of the cores into the receiving guides of the moulds, and means for releasing the cores from the core holders.
