Definitions

  • the present invention refers to a process for quickly preparing moulds for manufacturing clay articles, such as tiles and the like.
  • Such moulds are made of steel, and the steel has to be subjected to a special heat treatment in order to maintain for a long time a surface hard and strong enough for the intended uses.
  • a plaster support or insert is formed in the mould, and such support is coated with a material having very good properties of wear-resistance, such as a polymeric material filled with ceramic steels.
  • resin blocks are formed inside the mould, that are coated with the above mentioned material having very good properties of wear-resistance, and the so coated blocks are fitted in the mould and secured to the mould by proper means.
  • the above mentioned material having very good properties of wear-resistance used in bothe embodiments of the invention is a two-component compound formed by a polymeric matrix reinforced with ceramic steels.
  • numerals 1 and 3 indicate the positives of the desired manufactured articles in accordance with the above mentioned advanced prior technique.
  • Betwen said positives 1 and 3 a resin 5 is poured that forms, once set, the negative of the article to be manufactured.
  • This negative 5 is secured to the upper positive 1 by suitable fastening means, such as screws 7 o the like.
  • Fig. 3 shows first embodiment of the invention.
  • a support 11 of plaster or similar soft material is directly formed in the mould 9, and such support 11 is coated with a material 13 having very good properties of wear-resistance, such as a polymeric material reinforced with ceramic steels.
  • FIG. 4 A second embodiment of the invention is illustrated in Fig. 4.
  • two resin blocks 15 are formed that are then coated with the above mentioned wear-resistant material 13, the blocks 15 so coated are fitted in the mould 9 and there fastened with proper fastening means 17.
  • the wear-resistant material 13 used in both embodiments is preferably a two-component product constituted by a polymeric matrix reinforced with ceramic steels.
