Definitions

  • This invention relates to the quick replacement of those parts which determine the tile format in press-mounted moulds for forming ceramic tiles.
  • forming moulds are complex structures comprising a plate, known as the bench protector, which is securely fixed to the bed of the press.
  • Hydraulic cylinder-piston units also known as columns or feet, extend upwards from the bench protector plate to support a vertically movable upper die plate in which through seats are provided to create the forming cavities for the powder.
  • the bench protector plate In a position below the die plate, the bench protector plate carries a slab, known as the block, which is movable vertically relative to the bench protector plate by a series of rods rising from the press raising system and passing through holes in the bench protector plate to engage the block bilaterally.
  • a slab known as the block
  • a number of pads equal to the number of through cavities of the die plate are securely fixed on the block, on each pad there being fixed, generally by magnetic fixing, one of the two dies forming the rear surface or exposed surface of the tile.
  • Said two dies are known respectively as the reverse face die for the rear surface and the obverse face die for the exposed surface.
  • the tile format is defined by the die plate cavities and the dies, and to a certain extent by the underlying pads which must have dimensions just less than those of the dies.
  • the die plate must be released from its cylinder-piston support units and removed from the press.
  • the bed (consisting of the bench protector plate/block/bellows/feet) must then be detached and removed from the press.
  • the block of the new format must be remounted on the bench protector plate, the respective pads and dies must be mounted on the block and the die plate of the new format be remounted, after which lengthy and laborious mutual settings must be effected on the various parts before commencing the new production.
  • the object of this invention is to provide a mould having quickly interchangeable parts to enable the format to be easily changed in a short time, including the final setting operations.
  • the mould of the invention comprises a bench protector plate, a block associated with said bench protector plate by raising means, at least one pad securely fixed to said block, and a series of cylinder-piston units supporting a vertically movable die plate. It differs from the known art by a base plate fixed to the block by locking means operable from the outside and on which the pads are securely fixed, and a manipulator bar arranged to connect said die plate and said pads together to maintain the assembly coherent during the replacement.
  • the figures show the crosspiece 1 of the press raising system, on which the bench protector plate 2 is securely fixed.
  • the bilateral locking means between the rods 11 and block 3 are omitted as these are of usual type.
  • the rods 11 are operated hydraulically to raise the block 3 from the bench protector plate 2 when required.
  • a bellows 31 protects the region between the block 3 and bench protector plate 2 against dust.
  • Four hydraulic cylinder-piston units 22 extend upwards from the bench protector plate 2 to support the die plate 4 by four equidistant bushes 41, also known as loading spacers.
  • a screw 42 passing through the bush 41, fixes the die plate 4 to the piston rod of the cylinder-piston unit 22.
  • the die plate 4 comprises the cavities 43 within which the powder is pressed.
  • a plate 5, known as the pad linkage plate, is rested on and fixed to the block 3 by magnetic means 32, and has the same plan dimensions as the block.
  • the block 3 also comprises four seats 33 for four hydraulic cylinder-piston units 34 for raising the pad linkage plate 5 from the block after deactivating the magnetic means 32.
  • a number of pads 6 equal to the number of cavities 43 of the die plate 4 and having plan dimensions just less than those of the respective cavity are securely fixed by usual means, not shown, to the pad linkage plate 5.
  • the figures also show the press upper crosspiece 10 which by usual magnetic means supports the upper dies 101 to be inserted into the cavities of the die plate 4.
  • the invention is completed by a manipulator bar 8 (see Figure 3) which during format change maintains the die plate 4, the pads 6 and the pad linkage plate 5 joined together and centered, and by suitable spacers 81.
  • the format is changed in the following manner.
  • the die plate is lowered by operating the cylinder-piston units 22 until they are flush with, or slightly below, the upper face of the pads 6, the dies 61 then being removed after deactivating the magnetic locks ( Figure 2), while at the same time the block 3 is raised by the hydraulic rods 11 until it rests against the lower side of the die plate 4.
  • die plate 4 is again raised ( Figure 3), it is disengaged from the bushes 41, and spacers 81 having their top flush with the upper surface of the die plate are placed on the pads 6.
  • the manipulator bar 8 for maintaining the die plate, the pads and the underlying pad linkage plate 5 joined together as a single assembly is fixed onto the die plate 4 with the spacers 81 interposed.
  • the assembly can then be collected and removed from the press by a usual fork lift truck 100, after lowering the cylinder-piston units 34.
  • the assembly of the new format previously assembled outside the press is then mounted by the reverse operations.
