Definitions

  • the invention relates to a mold for the production of Shaped stones, especially made of flowable concrete, with one or more form nests, each one or several mold cores arranged on a core carrier plate for making recesses inside or on the Outside of the shaped block are assigned, the Mold cores after molding relative to the bottom of the Forming scraper plate vertically down to upper limit of the scraper plate are movable and then the stripper plate together with the mold cores relative to the shape in the horizontal direction from the Area of the form is retractable.
  • a double composite brick is made Concrete known that has projections and on its outsides Has depressions.
  • the wells are marked with a made open top and bottom mold on a Bottom plate is deposited.
  • the bottom plate is with openings provided, each with a vertical mandrel is movably guided.
  • the mold cores their dimensions correspond to the recesses on the finished stone, are arranged on a bottom plate Core carrier plate attached.
  • the core carrier plate Before pouring the concrete mass the core carrier plate with the Mold cores moved up. Then the shape The core carrier plate is then filled with the mold cores moved back down until the top edge of the mandrels is level with the top of the base plate, which serves as a wiper for the mold cores.
  • the table top with the lowered mold cores and the Core carrier plate moved horizontally to the side. For demolding the shape of the finished concrete block is up raised.
  • Such a shape can be used in conventional molding machines to whom the mold is placed on a vibrating table be used. Because the vibrating table vibrates is offset and in the known version with the shape the core carrier plate would rest on the vibrating table, it is not possible with this version, the core carrier plate with the mold cores relative to the vibrating table lower down. It would also be one in this case optimal transmission of vibrations from the vibrating table not guaranteed on the form, since between the Contact surface of the vibrating table and the scraper plate which rests on the mold, the core carrier plate is arranged.
  • the invention has for its object a form of to create a rational and largely automated series production of qualitative high-quality shaped stones with different recesses inside or on the outside of the shaped stone enable.
  • the advantages achieved with the invention are in particular in that the vibrations of the vibrating table over the underside of the Box and its top by the wiper plate is formed, transferred to the form in an optimal manner become.
  • the top of the box in the mold cores are retracted, including the stripper plate forms, the horizontal extension of the Box smoothed the underside of the molding, see above that a clean and smooth bottom surface of the finished Concrete block is guaranteed.
  • a mold is on a vibrating table 1 of a molding machine 2 3 deposed with several mold nests 4.
  • Form 3 is with lateral approaches 5 on vertically movable, by not shown piston-cylinder units drivable carriers 6 of the molding machine 2 interchangeably attached.
  • the core support plate 8 is housed vertically movable in a box 9, the top of which by a box 9 screwed wiper plate 10 is formed.
  • the Scraper plate 10 has bores 10 'which of the Mold cores 7 are vertically movable.
  • the bottom of the box 9 lies on the vibrating table 1 on.
  • On the short sides of the rectangular scraper plate 10, which projects beyond the box 9, are two each Piston rods 11 attached by piston-cylinder units 12, for the vertical lifting and lowering of the scraper plate 10 or the box 9 serve (left side of FIG. 1
  • Fig. 1 shows the connection of the Scraper plate 10 or box 9 with the core support plate 8 through stepped cylinder 13 attached to the core support plate 8 are attached and their pistons 14 also the transverse sides of the stripper plate 10 or on the box 9 attack.
  • step cylinder 13 is the Core support plate 8 at the four corners from box 9 led out (Fig. 4).
  • the step cylinders 13 are located on the right side of FIG. 1 behind the piston-cylinder units, not shown 12, which can be seen on the left side of FIG. 1.
  • the step cylinder 13 there is a vertical movement the core support plate 8 relative to the stripper plate 10 in Box 9 allows.
  • 2 and 3 is the arrangement the piston-cylinder units 12 and the stepped cylinder 13 shown enlarged as detail A and B of FIG. 1.
  • the piston-cylinder units 12 are supported by the carrier 15 connected to one another, which have lateral rollers 16 and on horizontal rails 17 of a frame 18 of the molding machine 2 are performed. That way, the one from the Box 9, the core support plate 8, the piston-cylinder units 12 and the stage cylinders 13 existing unit 19th Can be moved in the horizontal direction relative to Form 3.
  • the unit 19 is driven by a hydraulic cylinder 20, the piston rod 21 is attached to the box 9 (Fig. 6). To compensate for the vertical movement of the box 9, the connection between piston rod 21 and Box 9 on the one hand and hydraulic cylinder 20 and the Frame 18 on the other hand formed by joints 22 and 23.
  • the mold nests 4 are vertically movable in a known manner and driven by a piston-cylinder unit 24 Pressure plates 25 assigned to the filled Form nests 4 rest.
  • the mode of operation of the invention is as follows:
  • the box 9 placed on the vibrating table 1.
  • the carrier 6 of the Molding machine 2 are lowered until mold 3 is open the stripper plate 10 of the box 9 rests.
  • the core carrier plate 8 with the mold cores 7 through Actuation of the stepped cylinder 13 moves up and the Mold cores 7 moved into the mold cavities 4 (FIG. 1).
  • the mold nests 4 are filled with concrete mass.
  • Lowering the pressure plates 25 is the form 3 by vibrators 26, which are attached to the vibrating table 1, vibrated.
  • the box 9 is through Actuation of the piston-cylinder units 12 and 24 together moved up with the form 3 and the pressure plates 25 (Figs. 5 and 6). Then or simultaneously Core carrier plate 8 with the mold cores 7 by actuation the stepped cylinder 13 relative to the stripper plate 10 after moved down. Thereby, concrete residues are attached to the mold cores 7 stick, stripped by the stripper plate 10. The vertical movement of the core support plate 8 and the mold cores 7 down will end when the top of the Mold cores 7 on the same level with the top of the Scraper plate 10 is.
  • the unit 19 is again in its starting position retracted and together with the form 3 on the Vibrating table 1 set down.
  • the printing plates 25 remain in its upper position, not shown, so that the Mold cavities 4 can be filled in a known manner.
  • FIG. 8 to 11 Another embodiment of the invention is shown in FIG. 8 to 11 shown.
  • the vibrating table 1 is openwork and has two side walls 28, between which the box 9 with the core support plate 8, the stripper plate 10 and the Stage cylinders 13 is arranged.
  • In the side cheeks 28 there are guideways 29 for slidably receiving Guide pin 30, which on the long sides of the box 9th are attached.
  • the guideways 29, each of which two are arranged in a side cheek 28, run first horizontally and then in approximately vertical Direction obliquely downwards (Fig. 9).
  • To move of the box 9 in the guideways 29 serves the hydraulic cylinder 20, with its piston rod 21 over the joint 22 on the box 9 and via the joint 23 on the frame 18th is articulated.
  • the vibrators 26 are in this version screwed directly to the box 9, which thereby Partial function of shaking and compacting the shaped stones takes over.
  • the piston-cylinder units 11, 12 are no longer required in this version because the Vertical movement of the box 9 through the oblique course the guideways 29 is made possible.
  • cylindrical mold cores 7 instead of the cylindrical mold cores 7 also mold cores with others geometric shapes for making various recesses used in the stone or on the outside to e.g. a paving stone according to DE-A-43 17 To be able to manufacture 442.
  • the recesses can only enforce part of the shaped stone or they can be installed in stages.
  • inventive Form are any number of recesses of any size and form inside or on the outside of the shaped stone possible.
