Definitions

  • This invention relates in an entirely general manner to the ceramic tile production sector, and more particularly to a press of relatively low power for forming ceramic products of special type.
  • a typical use of the invention is in ceramics laboratories and in the small-scale manufacture of relatively small-dimension products such as small tile pieces, fillets, sections for covering concave and convex dihedral corners, sections for covering concave and convex trihedral corners, and endpieces.
  • said known low-power presses comprise:
  • the main object of the present invention is to satisfy said requirements within the context of a simple and rational construction.
  • a press comprising a horizontal fixed plate provided upperly with at least one part of a ceramic mould, and an overlying upwardly and downwardly slidable vertical flat frame which is lowerly provided with at least one ceramic mould part conjugate to the preceding and is raised and lowered by hydraulic means interposed between it and said plate.
  • said frame is in the form of a U-piece, the cross-member of which centrally carries, fixed thereto, said at least one conjugate ceramic mould part, and the arms of which are each provided with an end piston which is received in a hydraulic chamber associated with said plate and connected to a convenient hydraulic system.
  • said frame is in the form of a T-piece, the lateral arms of which support said at least one conjugate mould part, which is positioned symmetrically about the central rod, this latter being provided with an end piston which is slidable within a hydraulic chamber associated with said plate and connected to a convenient hydraulic system.
  • the press of the invention comprises a robust horizontally lying flat body 1 to be placed on a suitable support, not shown.
  • said ceramic mould is of the entering punch type, but there is nothing to prevent any other known type of ceramic mould from being associated with the invention.
  • Said mould part comprises at least one die 2, for example of the type for moulding the reverse face of a ceramic fillet, which is fixed to said body 1 and is slidingly mounted within a forming cavity 3 of a die box or die plate 4.
  • the die plate 4 is supported by at least two devices, not visible in Figure 1, arranged to lower and raise said die plate 4 respectively, to extract the formed fillet from the cavity 3 and to load into said cavity 3 the pulverulent material to be compacted.
  • a device of this kind which is of known type, is indicated in Figures 2 and 3 by the reference numeral 5.
  • a vertically lying flat frame 6 slidable upwards and downwards relative to the body 1.
  • said frame 6 is substantially in the form of a U-piece, under the cross-member of which there is positioned a die 7, for example of the type for moulding the front face of a ceramic fillet in combination with the underlying die 2.
  • the arms of said U-shaped frame 6 consist of two cylindrical bars 8 slidingly received in respective sleeves 9.
  • each sleeve 9 is composed of two coaxial parts, of which the upper part projects beyond the mould part 2-4, whereas the lower part projects below the body 1 and comprises a hydraulic chamber 10.
  • chamber 10 is served by two ducts 11 and 12 connected to a convenient hydraulic service circuit.
  • the frame 6 is in the form of a T-piece, the lateral arms 116 of which are lowerly provided with said two dies 7, and of which the central rod 108 consists of a cylindrical bar arranged to slide relative to the sleeve 9 as already stated.
  • mould parts 7 and 2-4 are arranged symmetrically about said rod 108.
  • sliding bearings such as those indicated by 33 in Figure 2 could be interposed between the die plate 4 and the sleeve.
  • two die plates can be provided each conjugate to the overlying dies 7.
