Definitions

  • the invention relates to a mold as the upper or lower form of a roof tile press.
  • Roof tile molds are known in various designs.
  • Usual press molds are, on the one hand, molds which consist of a plaster body enclosed by a metal frame, the surface of which is profiled for molding a compact (brick picture).
  • Another known press mold variant consists of a nickel-chrome steel block (NiCr) with a shaping surface profile.
  • NiCr nickel-chrome steel block
  • the plaster molds have the advantage that they are very light and inexpensive. Furthermore, good detachment of the wet molding from the mold with a plaster body is ensured.
  • their service life is relatively short, i.e. they need to be replaced frequently. Before a new plaster mold can be used in the frame, the old plaster insert must be knocked out of the frame each time.
  • the massive NiCr steel molds have a long service life, but are comparatively heavy and expensive;
  • the high-quality alloy ensures that there is no corrosion when it comes into contact with the moist clay compact, and offers good results Removal properties for the wet molding.
  • wear occurs, the entire mold must be replaced because the tile image is firmly molded with the mold.
  • a mold as an upper mold or lower mold for roof tile presses.
  • the die plate is formed by a stainless steel plate of small thickness.
  • the stainless steel material can be shaped precisely, which means that a precise die surface can be produced, and offers good release properties.
  • a stiffener is a plate made of a lower-quality metal, which is adjacent to the underside of the die plate and is strong enough in any case to support the die plate Record pressing force.
  • the overall material expenditure, and in particular the use of expensive materials is considerably reduced compared to known molds, as a result of which the cost and weight of the mold are reduced.
  • the stability of the stainless steel plate is much higher than that of a plaster mold, for example.
  • the frame and the lower stiffening are not wearing parts, so they remain reusable after the steel plate has worn out. If a die plate no longer achieves the required shape quality, it can be replaced with little effort without having to remove the entire mold.
  • the invention is explained below with reference to a preferred embodiment in the drawing.
  • the single figure shows the mold in a perspective, schematic representation with a cross section.
  • 11 is the die
  • 12 is a pressure-resistant metal frame
  • 13 is a die plate
  • 14 is a stiffening plate.
  • the frame 12 can be fastened to a press drum (not shown) as a frame for a lower mold or to a press ram (not shown) as a frame for an upper mold.
  • the frame 12 is preferably made of aluminum.
  • the shaping die plate 13 is releasably attached to the frame 12 and spans the frame opening.
  • the die plate 13 is a thin, pressed stainless steel plate.
  • the stiffening plate 14 connects to the underside of the die plate 13 in a form-fitting manner to increase the strength of the press mold.
  • the stiffening plate 14, like the frame, is preferably made of aluminum and in any case sufficiently strong to fully absorb the pressure.
  • transverse and / or longitudinal ribs can be formed on its underside.
  • the stiffening for the die plate can also be designed overall as a rib grid.
  • stiffening plate 14 and the corresponding die plates 13 in such a way that the frame 12 and stiffening plate 14 can even be used for pressing different brick shapes, thereby additionally reducing costs and labor.
  • the frame 12 is closed on its underside, and the space enclosed by the frame 12 and the die plate 13 is poured out with an incompressible material, such as synthetic resin or plaster, to further increase the stability.
  • an incompressible material such as synthetic resin or plaster
