Definitions

  • the invention relates to a mold for machine production of concrete blocks according to the generic term of claim 1 such forms or in the case of the manufacturers for whom such Forms are provided, there is a general problem that To guide the load so precisely that the stamps the mold chambers hit exactly. Even a small horizontal offset of the Load on the mold frame can damage the Stamping and the mold chamber walls cause effects as well on the manufactured concrete blocks.
  • the invention is based on the object with a relatively simple measure the entry of the stamp in the mold chambers, especially in the critical ones mentioned Improve shapes so that greater tolerances for the Horizontal offset can be allowed.
  • the stamp of one intended for straight curbs has a strong after printing surface area inclined below, with a vertical Side surface of the stamp forms a horizontal cutting edge. He is therefore also called a profile sword.
  • the inclined pressure surface area forms vertical end faces straight edge sections at least in the lower part.
  • the recess in the respective end wall of the molding chamber on the one hand delimited by the mold chamber side wall, which itself extends into the recess, and on the other hand by a inclined recess edge formed with the mold chamber end wall, the one with the inclined edge section of the stamp if possible runs exactly parallel.
  • the guide surface is a flat surface that is attached to the recess edge begins and with the mold chamber face forms an appropriately selectable angle. Is the angle steeper, so there is a larger horizontal offset in the direction of the Cutting the profile sword possible. At a flatter angle the recess will not be as deep.
  • the guide surface can also comprise a plurality of strip surfaces inclined to one another, the existing edges or fillets all to each other and to the Recess edges run parallel. Furthermore, the guide surface be one-dimensionally curved.
  • the recesses can each one to the end face of the Mold chamber have parallel bottom surface. This is recommended for example if the edge of the profile sword is not quite is sharp, but has a certain thickness. The depth of the Recess depends on the expected offset of the stamp.
  • the recesses can be liners or inserts made of a different material than the material of the mold walls contain.
  • the liner can be screwed on or on others Way to be attached.
  • stamp Cleaning elements are arranged, which when starting the Stamp out of the mold chamber or when lowering the mold chamber after removing the formwork from the concrete block, clean the recesses.
  • the cleaning elements can be brushed or optionally under Spring pressure or gravity pawls or horizontal be movable slide.
  • the invention also extends to molds with stamps pulled down to the corners or to a corner Have printing surface edges. This results in cutouts that extend over the corner of the molding chamber. they form in a manner of speaking, an inlet trough falling towards the molding chamber, which with horizontal offset of the incoming stamp with whose deep inclined edge sections in Step in line.
  • Figures 1-3 are an example in a simplified representation give a form for the production of curbs 1, of which one is shown in cross section in FIG.
  • One above and bottom open mold chamber 2 is by two side walls 3 and 4 and bounded by two end walls 5 and 6.
  • This form frame interacts with a load that is also guided in the stone paver in the height direction and on with the appropriate stamp attached.
  • stamp 7 belonging to the molding chamber 2 shown a so-called profile sword, is in the raised position the molding chamber 2 shown. It has a plate-shaped top Part 8, which is rounded into a wedge-shaped sword 9 passes, which has a cutting edge 10 below.
  • the plate-shaped Batch 8 is screwed to a screw-on plate 11 Stamp tubes 12 is welded, which in turn with the not shown load are connected.
  • a Stamp offset in the transverse direction of the elongated mold chamber is not critical. He can by the in this illustration Chamfer, not shown, caught on the upper edge of the side wall 3 become. In the event of an offset in the longitudinal direction of the side walls however, the touch occurs at the protruding corner, which leads to Leads to damage. For this reason, are in these places the end walls 5 and 6 recesses 13 and 14 attached, which in following are described in more detail.
  • Figure 4 shows the viewed from the rear part of the front wall 6 on the sword side, being for clarification the side wall 3 cut away and only dash-dotted is indicated.
  • This figure also shows the chamfer that was customary up to now 15 on the end wall 6 and 16 on the side wall 3.
  • the essential feature of the guide surface 17 and the The recess is the one formed with the inner surface of the end wall 6 Recess edge 18. It runs parallel to the inclined Print surface edge 19 of the sword 9.
  • the vertically movable Sword 9 is located so that its vertical surface in the plane of the inner surface of the side wall 3. So far so the sword is not offset horizontally.
  • Figure 5 illustrates that the angle that the guide surface 17 with the end wall 6 forms at the discretion of the designer. It four areas are indicated, which like book pages around the Recess edge 18 are foldable as an axis. Area 20 agrees with the guide surface 17 shown in thick lines match. The side faces that are the other Folding positions result are indicated in thin lines. Each the steeper the angle, the larger the approved Longitudinal offset of the stamp.
  • Figure 6 shows that the guide surface can also be kinked.
  • she consists of a flatter, parallel to the recess edge 18 Strip 21 and a steeper residual surface 22.
  • the recess has one bottom 23 parallel to end wall 6 and according to FIG One-dimensionally curved guide surface.
  • the height of the recess is selectable. Given the angle of the guide surface to the front wall this height affects the possible offset tolerance.
  • the lower one Tip of the guide surface should be omitted if the cutting edge 10 like indicated in Figure 4, blunted. This ensures that the stamp 7 shortly after centering the molding chamber seals.
  • FIG. 9 shows a further exemplary embodiment Recess at the corner of a rectangular molding chamber, where the stamp 24 has a horizontal printing surface, the shown corner is inclined downwards. This results in two inclined portions 25 and 26 of the printing surface edges which are shown in parallel by two recess edges 27 and 28.
  • the recess thus has two separated by a groove 29 Guide surfaces 30 and 31 for the two pressure surface edges 25 and 26.
