Definitions

  • the invention relates to a concrete molding machine for the production of shaped stones intended for paving, for example, having a shape having a multiplicity of mold cavities and a load plate which can be placed thereon and which closes and loads the mold cavities by means of stamp plates penetrating into them.
  • Concrete molding machines of this type are widely used for the production, in particular, of shaped stones intended for paving purposes, which may have a rectangular or square outline, but are often equipped with curved, limited projections and recesses such that projections penetrate into recesses in the adjacent shaped stone when the shaped stones are laid, that the remaining joints have the same strengths throughout.
  • molds made of steel, possibly also cast steel which have a large number of mold troughs provided on the same level, and after the concrete has been introduced, a load plate equipped with a large number of stamp plates is lowered or lowered onto the mold pivoted down that a stamp plate penetrates into a mold cavity.
  • the stamp plates form the upper surface of the shaped blocks and the chamfer that surrounds them, and by continued pressure in connection with vibrations, the concrete in the mold cavities is completely shaped and in particular compacted.
  • the stamp plates which are located within the mold cavities with little play and are usually made of steel or cast steel, strike the walls of the mold cavities when vibrating. Not only is this an undesirably high sound immission caused, there is also an unpleasantly strong abrasion if the stamp plates vibrate within the clear width of the upper regions of the mold cavities, whereby hard, granular components are formed in the gaps formed between the stamp plates and the walls of the mold cavities penetrate the concrete and act like a grinding paste. This wear is so severe that the punches only have a lifespan of 30,000 to at most 50,000 cycles, the concrete molding machine being able to carry out 3000 cycles per day, for example.
  • the stamps are already sanded off on the side and the walls of the mold are so worn that the dimensional accuracy of the stones as well as their surfaces are no longer able to meet the requirements.
  • the elaborate shapes can generally be done by cladding once. recondition, the stamp plates as pure wear parts are then considered used.
  • the invention is based on the task of simplifying the construction of B e-tonformmaschinen and in particular to extend the service life of both the mold and the die plates closing the mold cavities and thus to reduce the additional costs arising from wear, both through the replacement or the refurbishment of worn parts as well as the required assembly and downtimes.
  • stamp plates of the load plates being made of tough-elastic plastic.
  • Such stamp plates made of tough-elastic plastic not only wear themselves to a much lesser extent than the stamp plates made of steel or cast steel that have been used up to now, but also the walls of the mold troughs that come into contact with them, possibly via concrete components, are subject to a significantly reduced rate Wear.
  • stamp plates made of plastic show no tendency to attach concrete, so that the periodic mechanical cleaning of the stamp plates previously required can be omitted.
  • stamp plates made of polyamide, preferably PA 6 or PA 6.6.
  • stamp plates made of a plastic which has mechanical properties which are similar to those of the polyamide. In each of these cases it is possible to mechanically work out the stamp plates from the full material. With the often somewhat more complicated geometries of the shaped stones to be produced and the corresponding stamp plates, it often proves to be advantageous to produce these stamp plates by casting, injection molding or the like, or by curing or polymerizing them - in a mold in the desired dimensions.
  • the stamp plates are connected to the load plate by means of screws. It has proven useful here to embed head areas of the fastening screws in the stamp plates during the production thereof.
  • differently shaped bolts can also be used for fastening, for example bolts equipped with slots, which permit fastening by means of wedges penetrating through the slots. Because of the low tendency of the concrete to start, it has proven to be advantageous to choose and manufacture plastic inserts arranged in mold troughs according to a further feature of the innovation.
  • the invention relates to a conventional concrete molding machine for the production of shaped blocks, such as those used for paving courtyards, parking lots, driveways or the like.
  • the concrete molding machine has a shape that contains mold cavities for a large number of shaped stones. After the mold cavities have been filled with concrete, the mold is lowered or swung down linearly a load plate is applied, which is equipped on the front with a number of stamp plates corresponding to the number of mold cavities. When the load plate is lowered, these stamp plates penetrate into the mold troughs at least in some areas, and under the action of the pressure applied to the load plate, the surface of the concrete introduced into the mold troughs is shaped accordingly. Additional vibration at the same time compresses the concrete placed in the mold troughs.
  • FIG. 1 shows the front view of a stamp plate 1, the vertical section of which is shown in FIG. 2.
  • the stamp plate 1 shown in the figures consists of a polyamide.
  • the flat, rectangular end face 2 of the stamp plate 1 is truncated pyramid-like by oblique edge strips 3, which cause the edge chamfer of the shaped stone to be formed when it hits concrete in the associated mold cavity.
  • connection to the load plate is effected by fastening screws 4, the head regions 5 of which are embedded in the polyamide of the stamp plate, so that a special fastening of the fastening screws to the stamp plate is not required.
