Definitions

  • the present invention relates to an innovative mold for forming ceramic tiles.
  • the general purpose of the present invention is to remedy the above mentioned shortcomings by making available an innovative mold making unnecessary the changing of the mold with changes in formats or in conformation of the pressed product and thus reducing costs, space occupied, tooling times and the need of high capacity hoisting and handling equipment.
  • a mold for forming ceramic tiles with bottom die comprising a frame member having at least one seat to receive in a removable manner interchangeable inserts forming the pits of the pressing chamber with there being between the frame member and the inserts releasable locking mean for releasing the inserts from the seats.
  • FIG 1 shows a mold designated as a whole by reference number 10 for the forming of ceramic tiles realized in accordance with the present invention.
  • This mold has a bottom die comprising a frame member 11 equipped with at least one seat 12 which receives in a removable manner interchangeable inserts 13.
  • the inserts 13 form in turn pits 14 of the pressing chambers.
  • each insert 13 comprises a side frame 15 defining the pit which has side walls covered with plates 16 made of hardened metal such as for example tempered steel.
  • the plates can be removable for easy replacement.
  • FIGS 2 and 3 show a fixing realized with a screw 21 and a counterscrew 22.
  • the seat 12 contains a plurality of inserts side by side and aligned in a direction of extension of the locking means so that the inserts can all be positioned or removed with one simple operation.
  • the seat has a bottom open at the openings of the pits formed by the inserts so as to allow introduction into the pits of normal press planes not shown or further described because readily imaginable by those skilled in the art as is readily imaginable to those skilled in the art the press with all its production accessories.
  • the locking means comprise advantageously (FIG 3) on one side of the inserts first side walls 23, 24 tilted towards the seat so as to realize an undercut on that side of the inserts and on the other side of the inserts a member 18 for lateral thrust against the inserts.
  • the seat and insert walls which realize the undercut are advantageously tilted at an angle of between 2° and 8° and preferably around 5°.
  • the side walls are tilted.
  • the tilt is turned in the same direction as the tilt of the side walls 23, 24 and preferably at the same angle.
  • the insert can thus be inserted in the seat with an tilted movement as shown in broken lines at reference number 13' in FIG 3.
  • the tilted wall 24 of the inserts has a rounded base edge 25.
  • the thrust member is realized with a bar 18 which is extended for the entire extension of the row of inserts aligned in the seat and which is received parallel to the side of the inserts in a cavity 17 made in the side wall of the seat.
  • Plugs 26 at the two ends prevent abandonment of the cavity 17 by the bar while allowing the necessary locking and unlocking travel of the inserts. If the seat is made by milling with accurate machining of the tilted walls there can also be plugs 30 for closing the passage of the cutters at the ends of the tilted walls 23.
  • the bar 18 is thrust against the inserts by screw members 19 distributed along the extension of the bar and facing with their handling head on one side 27 of the frame member.
  • the bar 18 rests on and pushes the inserts at a surface 28 of the insert which is tilted to have at the point of contact with the bar a normal turned downward so as to produce a thrust on the insert having a component directed toward the bottom of the seat. In this manner the secure and accurate resting of the insert on the shelved bottom 29 of the seat is assured.
  • the contact point tangent between the bar and the surface of the insert be tilted at an angle of between 85° and 70° and preferably around 80°. In the maximum thrust position the bar is lodged between the tilted surface 28 and the upper surface of the cavity 17.
  • a mold in accordance with the present invention allows fast change depending on requirements of the profile of the pressing chamber (bottom die pit) while keeping the mold in position in the press and merely replacing the insert.
  • the precision striker consisting of the shelved bottom of the seat and the tilted wall opposite the thrust means (surfaces machinable with high precision) allows keeping high precision in the mold after assembly and reassembly of the inserts with no need of resetting operations.
