Definitions

  • the invention relates to a mold for machine production of concrete moldings with a mold base with at least a mold chamber and a mold top with one Load plate and as many stamps as mold chambers available.
  • the filling of the lower mold parts of such molds in the Manufacturing machine is carried out with a so-called filling car.
  • This is a flat funnel that contains the molding material and back and forth directly over the upper edges of the molding chambers is moved. The material falls into the chambers and gets flush on the way back from the edge of the filling truck stripped.
  • the distribution of the is only limited free-flowing concrete mass in the filling truck mostly different and depending on the position of the individual chambers within the mold or depending on the size of the mold chamber base necessarily different crossing times for the sinking of the molding material into the chambers To be available. The even filling of the mold chambers is therefore problematic.
  • US-A-3,222,748 is a stone making machine become known, which includes a form as a tool, the one rigid upper part with stamp and a lower part with Mold chamber includes.
  • the top part has a Fastening plate on which the stamp for manufacturing the shape of the stones is attached.
  • a The height of the stamp is adjustable within the shape not provided.
  • the invention has for its object a form to indicate with which it remains unchanged filling technology is possible to use concrete bodies with a highly uniform density, uniform height and surface structure manufacture.
  • the basic idea is a two-stage Conduct compression processes in such a way that first with compliant stamps (under air pressure) is pre-compressed and after refilling the created with different depth chamber cavities located at the same height and parallel to the molding table Post-stamping or a post-parallel stamp becomes.
  • the parallelism to the form table comes about as soon as the air pressure is so far lowered that the pressure plate of the Stamp overcoming the force of a pressure medium chamber comes to rest with a movable wall at the stops. at this densification comes down very precisely to the Setting the reduced air pressure on. It will in particular suggested that to take full advantage of the subsequently described impact of air pressure is further reduced during the post-compression phase.
  • the Lowering can happen continuously.
  • each stamp essentially works the same force. From this even compression result in the different presupposed here Filling the chambers semi-finished moldings from clearly of different heights. So with the second filling where a lot of material is missing, a lot of refilled, where this refill due to the relatively small Refill a complete fill of the existing ones Creates voids. Overall, the sums are over the first and second filling quantities per chamber are almost the same, see above that shaped bodies arise, the height of which is practical Accuracy requirements of e.g. B. 1 mm corresponds best and the same density and therefore the same strength to have.
  • a preferred development of the invention is how mentioned, assume that the pressure medium chamber at the bottom Stamp arranged near the movable pressure plate is. It is suggested that on each stamp between a footplate firmly connected to the stamp shaft and an insert is arranged on the pressure plate, which is an upper part with an upper plate and one opposite this lower part guided in height with a lower plate has, the upper plate with the base plate and the lower plate is screwed to the pressure plate.
  • the Insert also contains at least one with compressed air acted upon bellows and the stops to limit the Stroke range of the two parts of the insert.
  • interlocking Guide mandrels and sleeves are preferably interlocking Guide mandrels and sleeves arranged.
  • the stamp shown is guided vertically, the stroke in the example is about 10 mm.
  • the stamp consists of a Stamp shaft 2 made of square tube, a head plate 3, one Base plate 4 and a pressure plate 5 screwed to it, their edge formation with a downward-facing cutting edge the chamfer of the to be finished with this shape Concrete paving stone forms.
  • the head plate 3 of the stamp is guided in a membrane receiving part 6, which together with a retaining ring 7 by means of screws 8 on the load plate 1 is screwed on.
  • the stroke of the head plate 3 and thus the whole stamp is above by a stop surface 9 and limited below by the retaining ring 7.
  • Spring screws 10 pass through the load plate 1 and the membrane receiving part 6 slidably with their upper cylindrical Shaft sections and are with the lower shaft sections screwed into the head plate 3. Between the heads of the Spring screws 10 and the load plate 1 are compression springs 11 clamped, the top plate 3 when the membrane is relaxed pull up to the stop surface 9.
  • a membrane 12 On a central thin plate section of the Membrane receiving part 6 is a membrane 12 from below hung up and between this section and one Fastening ring 13 tightly clamped. The latter is with Screws 14 screwed on.
  • the membrane 12 can on the Put head plate 3 and this against the force of Press the compression springs 11 down as far as they will go if through a line 15 which by means of a Diaphragm receiving part 6 through screw 16 is connected to compressed air through the membrane 12 completed interior penetrates.
  • Line 15 is on a distributor 17 connected, which in turn via a Three-way valve 18 to a compressed air supply line 19 relevant stone making machine is connected.
  • the three-way valve 18 could of course with one or two pressure reducing valves can be added to it allow for the different compression phases set appropriately different pressures.
  • FIG. 2 In the embodiment of FIG. 2 are on one Load plate 1 'attached stiffening rails 20 shown.
  • the stamp shaft 2 ' is firmly attached here the load plate 1 'welded and carries a thin bottom Base plate 4 '.

  • On the membrane 13 is in direct contact with it.
  • a the hub of the Pressure plate 5 'bridging sealing ring 22 prevents this Penetration of concrete slurry into the space between the Pressure plate and the diaphragm receiving part.
  • individual pressure rooms via lines 15 'with a Distributor 17 'connected the internal pressure as in first example can be controlled.
  • the insert 23 comprises two mutually movable Assemblies by an upper plate 24 or a lower Plate 25 are characterized.
  • On the top plate 24 a guide sleeve 26 under each punch shaft 2 ′′ attached with a guide pin 27 on the lower Plate interacts.
  • On the lower plate 25 are also four spacer strips 28 to joined together to form a square 31 attached.
  • 3 shows a longitudinal bar 28 and Fig. 5 in a single representation a cross bar 30. Die Longitudinal strips each have two double-T-shaped cutouts 32 on with double-T-shaped stop pieces 33 interact. The latter are on the upper plate 24 with each two screws 34 firmly connected.
  • bolts 35 are provided which have multiple functions to have. Since they all plates and the spacers in in the vertical direction, they initially appear next to the guide sleeves 26 and guide pin 27 as Management bodies with. Then connect the pressure plate 5 '' with the lower plate 25. You are in the pressure plate 5 ''. screwed in and a nut 36 tensions the lower two Plates together. To make room for the nuts 36 have the spacer strips 28 to 31 under their bores 37 for the screw bolts 35 rectangular edge recesses 38 on. And finally, the bolts 35 are used Support of compression springs 39, which the lower assembly of the Cushion insert 23 as it moves down. The Compression springs 39 are interposed between discs the base plate 4 '' and the respective head of the bolts 35 clamped.

  • the mode of operation corresponds to that of the above Embodiments.
  • Slack when not under pressure Bellows 40 are due to the spring action of the spacers 28 to 31 on the upper plate 24.
  • 3 shows the Position with pressurized bellows 40. Its strength overcomes the restoring forces of the springs 39, but the Downward movement limited by the double T-shaped Stop pieces 33, which on the through the recesses 32nd formed projections come to rest.
  • the inserts 23 can be of the required dimensions for Stamps of every shape and size are prefabricated separately, resulting in a significantly cheaper workflow at Manufacturing leads. If necessary, the Pressure plates 5 '', e.g. B. when worn, just as easily have been replaced so far.
  • FIG. 6 The embodiment of Figure 6 is intended to indicate how a larger printing plate can be attached to a stamp in the sense of the invention.
  • Combined two-way stops 45 and, on the other hand, spacers 46 are used, which can be arranged in a suitable manner distributed over the surface of the pressure plate 47 in question.
