Definitions

  • the present invention relates to an installation for positioning and clamping foundry molds.
  • the installation consists of at least one blind mold holder frame comprising a casting well open downwards, a transfer means in translation, at least one substantially vertical suspension jack and at least one substantially vertical clamping cylinder, the casting station being located on the casting nose of the melter.
  • the present invention provides a clamping installation which can be used for molds of different dimensions.
  • the blind sand molds each comprise a downwardly open pouring well, supplied via a pouring nose connected to a metal alloy pouring ladle, and means for applying the base of the pouring well to the upper opening of the pouring noses, which can be of different heights, depending on the configuration.
  • the frame comprises retractable cleats between the open and closed positions and at least one mold-carrier plate, the bearing face of the cleats in the closed position and the lower part of the mold tray are in the same horizontal plane.
  • the installation according to the invention of the type allowing repetitive pouring in which the transfer means carries a member for gripping and suspending the frame, is characterized in that the member for gripping and suspending the frame of the transfer means, includes cylinder for hanging an upper plate from the frame, and on this plate, the clamping cylinder, the head directed downwards is linked, free in rotation, by means of a ball joint, to a clamping plate.
  • the frame is guided vertically by at least one vertical rod.
  • the tabs are calibrated so that the bearing faces form a horizontal plane on which is placed the mold carrier plate. This plane is perpendicular to said vertical rod.
  • the subject of the invention is also an installation for positioning and clamping a blind sand foundry mold for the upward casting of metal alloy; the blind sand mold comprising a pouring open open well, via a pouring nose connected to a metal alloy pouring ladle, and means for applying the base of the pouring well to the upper opening of the nose casting characterized in that the installation is as defined above.
  • the installation shown in the drawing comprises a frame 1 in which is fixed a blind mold 2 comprising a pouring well 3 open downwards. It is of the type allowing repetitive pouring and further comprises a known horizontal transfer means 4 such as, for example, from patent FR-A 2,533,847, patented by the Applicant.
  • the transfer means carries, according to the invention, a member for gripping and suspending the frame.
  • the installation is intended to automatically position and tighten repeatedly, a mold 2 on an upward flow channel 5.
  • the frame 1 comprises at its upper part a plate 6, substantially horizontal and assumed to be rectangular.
  • the upper plate 6 is fixedly linked to four rods 7, two of which are not shown, for suspending the mold, descending vertically, and each comprising at their lower end a rotary horizontal cleat 8, for supporting the mold carrier plate 9 of the mold 2; each cleat 8 being retractable between an open position of the frame 1 and a closed or gripped position under the underside 10 of the mold carrier plate 9 of the mold 2.
  • the blind sand mold 2 is centered on the mold carrier plate 9 and clamped between said plate 9 and the upper clamping plate 11 by means of a double-acting clamping cylinder 12, the head 13 of which pointing downwards is linked, free in rotation, by a ball joint 14, to the clamping plate 11 of the mold 2.
  • the body 17 of the jack 12 is linked to the plate 6.
  • the rotation allowed by the ball 14 makes it possible to use a mold, the upper face of which, represented in dashed dashed lines, is in an inclined plane with respect to the plane from the underside.
  • the lower face of the upper plate 11 being larger or of the same dimension as the upper face of the mold 2.
  • the mold 2 is applied to the upper face of an intermediate wear device 15.
  • the frame 1 is moved in translation by the transfer means 4.
  • the transfer means 4 carries a member for gripping and suspending the frame which comprises a double-acting cylinder 18 for suspending the upper plate 6 of the frame 1.
  • the cylinder 18 is directed downwards and its head 19 carries the frame 1.
  • the mold 2 arrives by a conveying means inside the frame 2, the cleats being in the open position.
  • the tabs 8 are returned to the gripping position.
  • the mold can no longer leave the frame 2.
  • the tabs are adjusted so that their bearing face and the lower part of the mold carrier plate 9 are now in the same horizontal plane.
  • the pouring well 3 of the mold 2 opening downwards leads to the vacuum.
  • the clamping cylinder 12 presses the mold 2 and binds it to the frame by clamping, the mold 2 not having been moved relative to the frame 1.
  • the translational transfer means 4 places the frame 1 containing the mold 2 above the feed chute 16.
  • the jack 18 descends the frame 1 so as to put the mold 2 in the casting position.
  • the clamping cylinder 12 exerts pressure directed downwards, greater than the pressure supplied by the suspension cylinder (s) 18 for positioning and holding the mold 2 on the intermediate wear device 15.
  • the height of the second mold may be different from that of the first, the stroke of the jack 12 adapting to the height of the mold.
