Definitions

  • the invention relates to a multi-chamber mold for the mechanical production of moldings made of concrete according to the preamble of claim 1.
  • Examples of the moldings to be produced are shown spatially in Figures 1 and 2 of the drawing. They are concrete paving stones that form a bond even in the vertical direction of loading and are therefore suitable for heavily used paving surfaces such as pedestrian zones, airfields, fire brigade exits and the like. The individual stone cannot be twisted or pulled out in the pavement bandage.
  • Such moldings are assumed to be known. Their essential design feature is that they have lateral depressions in the lower area and lateral projections in the upper area and can therefore not be produced in conventional molding devices.
  • the moldings in question are to be distinguished from those which have lateral projections in the lower region and therefore require molds with a split load.
  • the disadvantage is that, on the one hand, the manufacturing process is time-consuming and cumbersome, because before the demolding, which is done by raising the mold frame, the drawing plate must be pulled out of the mold frame horizontally and transversely to the direction of production and must be used again before the next filling.
  • So-called rotary table presses for producing such concrete paving stones are also known.
  • Six mold chambers are arranged on a turntable. They are filled, stamped and demolded in an angular cycle. The most important thing is a turning device, with the help of which the individual mold is turned over by 180 ° for demoulding, as when emptying a pudding mold (overhead production).
  • the invention has for its object to propose a relatively simple and inexpensive molding device for the production of moldings of the type described in the introduction, which can be used in modern high-performance stone pavers and enables the simultaneous production of several moldings in a ready-to-install arrangement.
  • a split load molding device i.e. with several relatively vertically movable stamps per molding chamber or molding, supplemented by a horizontal slide, which no longer has to be moved over the entire width or length of the molding frame, but only within a small stroke range in the order of the depth of the lateral recesses of the die to be produced Molded body.
  • the slide is moved with one or a few working cylinders, for example hydraulic cylinders controlled by the production machine, between a working position and a demolding position.
  • the working speed or production output is practically not reduced compared to the values that can be achieved today in the production of concrete paving stones.
  • an arrangement-appropriate arrangement of the concrete bodies produced can be achieved with a single slide.
  • the window recesses of the slide must be at least as large as the projection area of a molded body on its base. Certain marginal areas the window recesses form the underside of the overlapping parts in the working position of the slide, in contrast, in the demolding position, these edge parts are withdrawn so far that they pass the overlapping parts of the molded body when the lower mold part is raised.
  • a group of separate stamps is preferably provided on the upper part of the mold, the printing surface of which corresponds to the projection surface only of the lower grip parts, these stamps leading into the molding material in advance of the stamps which form the higher visible surface in order to cleanly compress these lower grip parts and their surface to shape.
  • stamps leading into the molding material in advance of the stamps which form the higher visible surface in order to cleanly compress these lower grip parts and their surface to shape.
  • the mold frame be provided on its underside with attachment parts which are of the same height as the shape-effective edge parts of the slide and form the side surfaces of the lower grip parts of the molded body.
  • attachment parts can be used to participate in the horizontal guidance of the slide and to support its weight.
  • the attachment parts have horizontal support projections which partially engage under the slide.
  • An essential development of the invention consists in that several individually or jointly drivable slides are arranged one above the other on the underside of the mold frame.
  • two slides running in opposite directions in an axis of movement can be provided, which consist of flat metal and have shape-effective window edge regions of increased thickness, the edge regions of one slider projecting beyond its flat metal surface and into the corresponding window recesses of the other slider intervention. It is only a question of dimensioning the window cutouts in order to achieve that in the extended position, ie in the demolding position of the slide, the remaining opening allows the entire molded body to pass through, ie it is at least as large as its projection surface.
  • the slider or slides can have elongated holes which are penetrated by guide bolts attached to the mold frame.
  • the guide pins can be equipped with roller bearings to reduce friction.
  • the lifting cylinders provided for driving them can act in the longitudinal direction of the mold frame. This makes it easier to accommodate the lifting cylinders.
  • the drive forces are redirected by the slide guides.
  • the shaping device is replaced by a production machine Relieved and accelerated if quick-connect couplings are provided on the hydraulic connecting lines of the cylinders.
  • quick-release and reattachable snap connections are expediently used, since the sliders are expediently removed from the mold frame for cleaning after the end of production (at the end of work) and then reassembled.
  • the slide (s) be held on the mold frame with the aid of rotary latches, spring elements forcing the rotary latch into a closed position.
  • an (auxiliary) device is proposed, which is placed on the molding table and which is designed such that when the mold frame is lowered onto this dismantling assembly device, the rotary latches are either opened or closed automatically.
  • the last-mentioned device may have height-adjustable stop means, which act on the rotary latches and / or the spring elements when the mold frame is lowered and bring about a movement or relief of the same. So you only need to put this device on the molding table and move the molding frame down in manual control mode. The slides are then uncoupled automatically and remain on the device. After cleaning, they are put back on the device. Then you move the mold frame down again. The sliders are automatically picked up and locked again.
  • the square concrete paving stone shown in Fig. 1 is vertically connected with its neighboring stones. It has lower gripping strips 1 on two colliding longitudinal sides, which extend almost over the entire side length and are slightly chamfered on the surface in a wedge shape. Corresponding grooves 2 are provided at the bottom on the other two sides, which are at the rear in FIG. 1, which go under the visible surface and can accommodate the lower gripping strips of the neighboring stones. A fragment 3 of an adjacent stone is indicated.
  • FIGS. 3 to 11 A multi-chamber molding device for producing such concrete paving stones is shown in FIGS. 3 to 11. It is particularly simple since the lower mold part has only one slide 4 with window cutouts 5.
  • the mold frame 6 as a whole is shown in FIG. 3.
  • FIGS. 4 and 5 show only one molding chamber 7 in enlarged detail.
  • Figures 6 and 7 show only the slide 4 in a corresponding enlargement.
  • the rectangular mold frame 6 has twelve mold chambers 7. They are all aligned in the same way, so that the stones are arranged to be laid after demolding. The stones of a layer only need to be pushed together for transport on the pallet.
  • the form frame consists of a steel plate with a double wear plate.
  • the mold chambers 7 are z. B. cut out with a laser beam.
  • Protruding strips 8 on two opposite sides serve to receive the mold frame in the machine.
  • the filling truck runs on two prismatic rails 9.
  • the form frame is stiffened by various ribs, not individually identified.
  • attachment angles 10 z are on the underside of the molding frame. B. attached with the help of screws 11. These have the same height as the slide 4 to be described below.
  • the attachment angles 10 are also cut out of a correspondingly thick flat material. They have the same cross-section over their entire length and are divided into two long legs with short, right-angled inward projections which form the end faces 12 (FIG. 1) of the lower gripping strips 1. Some of the attachment angles 10 have a strip-shaped support projection 13 on the leg extending in the transverse direction of the shape, which serves as an additional sliding guide for the slide 4.
  • the slide 4 also cut from a steel plate, has relatively thin bars. Its window cutouts 5 are so large that they encompass the molding chambers 7 and the attachment angles 10.
  • the slide bars are widened on the right and lower side of each window recess 5 according to FIG. 7.
  • Those standing in the window widened parts 14 form the grooves 2 of the stone to be shaped. They are chamfered at the top towards the edge.
  • These important parts 14 are able to move into the molding chamber. They then abut the end faces of the small extensions of the attachment angles 10 and form - in plan view - a complete frame with a square opening. However, this square opening does not correspond to the position of the visible surface of the concrete paving stone in the form, as will be explained further.
  • the slide 4 has a plurality of rectangular tabs 15 in the edge, in each of which an elongated hole 16 running at 45 ° is formed.
  • a shoulder 17 is worked out on the underside around the elongated hole.
  • the slide has groove-like cutouts 18 on the underside, which also extend under the widened portions 14. In these cutouts 18, the support projections 13 fit, so that the latter, when assembled, as shown in FIG. 8, reach under the slide and support it without obstructing its mobility and hold it on the mold frame 6.
  • the slide is thus movable on the mold frame in the 45 ° direction. It is driven by two hydraulic lifting cylinders 19 (FIG. 3) which are articulated on the one hand on the mold frame and on the other hand on the slide.
  • the slide has tabs 20 projecting laterally, to which, as indicated by bores, the joint caps of the piston rods are screwed on.
  • a threaded pin 22 equipped with a ball bearing 21 is from below screwed into the mold frame 6.
  • a head plate 23 is then screwed onto the pin by means of a countersunk screw 24. This head plate 23 engages over the shoulder 17 of the elongated hole and thus locks the slide on the mold frame.
  • the associated molded upper part is shown in principle in FIGS. 9 and 10.
  • the horizontal section of the pair of punches for a molding chamber is arranged in the same way as the molding chambers themselves.
  • the punches are separated into two groups, the square so-called pressure plates 25 forming one group and the deeper angular punches 26 forming the other group.
  • the punches 26 are fastened directly via pressure rods 27 to a load plate 28, which, moreover, has a stiffening rib mechanism and connecting elements for attachment to the bear of the molding machine.
  • the pressure plates 25, on the other hand, which form the visible side of the concrete paving stone, are fastened via four punch shafts 29 to a common plate 30 which is suspended from the load plate 28 in a freely movable manner by means of supporting bolts 31.
  • the angular punches 26 penetrate deeper into the filled molding chamber, while the pressure plates 25 initially rest on the molding material only because of their own weight. With increasing compression under the action of the vibrating forces, the spacer strips of the plate 30 rest against the load plate 28, as is shown in the left half of FIG. 9 for clarification. This is the final position in the molding process. The rest position of this stamp is shown on the right in FIG. 9.
  • the slider 4 has moved to the top left according to FIG. 5.
  • the widened portion 14 of the slide projects into the molding chamber 7.
  • the pressure plate 25 lies with its right and its lower edge (according to FIG. 10) on the corresponding one Edges of the molding chamber 7. It also compresses the material over the widened parts 14 of the slide.
  • the angular punch 26, however, rests on the other two edges of the molding chamber. It compresses the material over the lower gripping strips 1 of the concrete paving stone and forms its surface.
  • the slide is moved to the bottom right out of the molding chamber with reference to FIG. 5, so that the full outline of the molding chamber is exposed and the molded body can thus be removed from the mold by raising the upper mold part and remains on the molding table.
  • the production of the concrete paving stone shown in FIG. 2 is described as a further exemplary embodiment. It has a square visible surface chamfered on the edge as usual and on each side two projecting cams 40 which are triangular in plan and two recesses 41 which, with their likewise triangular plan form, can suitably accommodate cams from neighboring stones.
  • the cams and recesses on the invisible backs of the concrete paving stone are arranged so that the stones can all be made in the same orientation and then simply pushed together.
  • the cams 40 are chamfered at the top towards the tip. They form the lower grip areas of this stone, while the areas above the cutouts 41 are to be addressed as overlap areas in this case.
  • the vertical surfaces of the cams and the recesses are at right angles to each other and form an angle of 45 ° to the side surfaces of the stone.
  • Several stones pushed together up to the stop stand in a vertical connection to each other. Due to the pointed shape, the cams and recesses easily find one another.
  • the direction of collapse can advantageously deviate from the edge direction by up to 45 °.
  • FIGS. 12 to 24 The shaping device for producing this concrete paving stone is shown in FIGS. 12 to 24.
  • the last-mentioned figure shows the entire molding frame 42.
  • Six molding chambers 43 are provided and two lifting cylinders 44, each lifting cylinder being articulated on the two slides used here, so that they can be pushed together or apart.
  • FIGS. 12 and 13 show a section of the molding frame 42 with only one molding chamber and on a larger scale.
  • the molding chamber 43 represents the outline of the concrete paving stone to be molded. From the sectional view it can be seen that a relatively thin plate has been used to produce the molding frame , wherein by placing a mold chamber frame 46 on the underside thereof, the mold chamber is given a greater depth.
  • FIG. 15 An upper slide 48 (FIG. 15) sits immediately below the molding frame 42 and a lower slide 49 (FIG. 17) adjoins this. From the cross sections according to FIGS. 14 and 16 it can be seen that both slides consist of a relatively thin flat material with originally square window cutouts 50 and 51, respectively.
  • an overall angular shaped piece 52 is inserted into the window cutout, which abuts two window edges and is flush with the surface of the slide at the top.
  • This shaped piece 52 has two projections 53 and two notches 54 on each side. The projections 53 form the recesses 41 of the stone.
  • the notches 54 form the side surface of the protrusions 40 of the stone, while the surface of these protrusions 40 of special stamps which will be discussed later.
  • a shaped piece 55 is inserted into the window cutouts 51 in such a way that it projects above the flat material thickness of the slide 48 over the surface of the slide 49.
  • Both fittings 52 and 55 are of the same height. Both abut the mold chamber frame 46 and are therefore at the same level. With their undersides, the shaped pieces 52 and 55 rest on the molding table.
  • Guide pins 56 engage in oblong holes 57 and 58 of the two sliders 48 and 49, respectively, with head disks 59 screwed onto the guide pins 56 (shown in FIG. 18) holding the sliders on the mold frame.
  • FIGS. 18 and 20 show the assembled lower mold part in the open or closed position.
  • the top views according to FIGS. 19 and 21 are schematic insofar as parts of the slides which lie under the mold frame are shown in solid lines in the interest of clarity.

  • the elongated holes 57 of the upper slide are shown in broken lines and the elongated holes 58 of the lower slide are shown in solid lines.
  • Figures 20 and 21 show the closed shape, ready for filling. It can be seen that the four projections 53 of the upper slide and the four corresponding projections on the shaped piece 55 of the lower slide project into the window cutout 43 of the mold frame. In this respect, the remaining clear opening according to FIG. 21 differs from the molding chamber 43.
  • the notches 54 of the molding 52 and the corresponding notches of the molding 55 are congruent under the eight notches of the molding frame 42.
