Definitions

  • the invention relates to a mold for the production of molded blocks, in particular from flowable concrete with one or more mold nests, which are delimited by vertical mold walls, wherein at least one mold wall runs obliquely and includes an upwardly open angle with the opposite mold wall.
  • the mold When producing concrete blocks in molds with straight, vertical side walls, the mold is usually subtracted from the concrete block to demould the finished concrete block.
  • the vertical side walls of the mold move along the outside of the concrete block, so that a smooth line is created, which gives the concrete block a pleasing appearance and prevents the formation of voids and unevenness on the outside of the concrete block during demolding.
  • this known manufacturing method it is not possible to produce shaped stones with a side wall inclined to the vertical, for example stair treads.
  • the invention has for its object to provide a shape of the type mentioned, which ensures a precise shape and a clean, smooth surface of the finished stone with rational production in the case of shaped stones with at least one sloping side wall.
  • the object is achieved in that the oblique mold walls of the mold cavities can be moved upwards in the direction of their bevel individually or together for demolding the finished molded block.
  • the advantages achieved with the invention consist in particular in that, as a result of the mold wall which can be moved in the direction of the desired bevel during demolding, the surface of the molded block is smoothed out. This gives the sloping side wall of the finished molded block a clean and smooth surface in the same way as the vertical side walls, which are also smoothed out when the mold is removed by lifting the mold vertically. In addition, self-cleaning of the mold walls is achieved.
  • a mold 3 with a plurality of mold nests 4 is arranged on a vibrating table 1 of a molding machine 2 with the interposition of a base board 5.
  • the mold 3 is fastened in an exchangeable manner to the vertically movable supports 7 of the molding machine 2, which can be driven by piston-cylinder units (not shown).
  • the mold nests 4 are assigned in a known manner vertically movable, driven by a piston-cylinder unit 8 pressure plates 9, which rest on the mold nests 4 filled with concrete mass.
  • the mold cavities 4 are located in a mold insert 10 which is firmly connected to the mold 3 by a releasable clamping connection (FIG. 3).
  • the mold insert 10 has three mold cavities 4 in the exemplary embodiment.
  • Each mold cavity 4 is delimited by three vertical mold walls 11 and an inclined, movable mold wall 12, which encloses an upwardly open angle with the opposite mold wall 11.
  • Fig. 1 is the oblique Molded wall 12 is trapezoidal in cross-section with an inclined inner surface which bears against an inclined control surface 13 of the pressure plate 9.
  • the bevel of the control surface 13 corresponds to the bevel of the mold wall 12.
  • the bevel mold wall 12 gives the finished molded block, for example a step, the desired bevel on one side.
  • the three inclined mold walls 12 of the three mold cavities 4 are each fastened to a carrier 14, the ends of which are guided outwards through openings 15 in the mold walls 11 and are each connected to a piston rod 16 of single-acting hydraulic cylinders 17 arranged laterally on the mold 3 ( 3 and 5).
  • the piston rod 16 is surrounded by spacer tubes 18 and bearing bushes 19 which are clamped against one another with a screw 20 at the end of the piston rod 16.
  • the bearing bush 19 is clamped between the spacer tube 18 and the carrier 14, which is penetrated by the piston rod 16 (FIG. 5).
  • the bearing bushes 19 are slidably mounted in bearings 21 which are fastened to the underside of a base plate 22 (FIGS. 4 and 6). In this way, a horizontally movable unit is formed within the mold 3, which consists of the three inclined mold walls 12, the supports 14 and the piston rods 16 of the hydraulic cylinders 17 integrated in the mold 3.
  • the mold cavities 4 are first filled with concrete, shaken and closed by lowering the pressure plates 9 into the position shown in FIG. 1. After the filling and shaking process, the mold 3 is raised by the drivable carriers 7 to demold the finished molded blocks into the position according to FIG. 2. During the vertical movement of the mold 3 upwards, the inclined inner surface of the mold wall 12 slides along the control surface 13 of the pressure plate 9. This creates a horizontal movement of the mold walls 12, the carrier 14 and the piston rods 16, since the single-acting hydraulic cylinders 17 are depressurized and the pistons are pushed back against the resistance of the hydraulic fluid flowing away.
  • a link control located outside the mold cavity 4 can also be used, which controls an obliquely upward direction Movement of the side wall 12 caused by a simulated movement.
  • shaped blocks with geometrically differently shaped side walls for example also curved side walls, can be produced with the same advantages.
