Definitions

  • the invention relates to a process for producting pressed vibrated concrete blocks in a mold closed at its bottom with a plate.
  • the object of the invention is to perform a process of the above specified kind, which is achieved in a simpler and faster manner than the known processes, whereby a higher productivity can be obtained.
  • the invention provides also a particular machine for carrying out the process according to Claim 1.
  • the said machine is characterized in Claim 3.
  • Figure 1 there is shown the mold 1 in its end-of-stroke block-delivery position, the mold cavities 2, the countermold 3 in its uppermost rest position, the countermold male portions 4 which have a shape that mates the shape of the mold cavities 2.
  • the components 1 and 3 are connected to respective means to be described later, for guiding and vertically displacing the said components, which are equipped with respective not-shown vibrators.
  • the horizontal plate 5 is located at a short distance from the ground S and is connected to guide and translation means that upon control place this plate beneath the mold bottom, or withdraw the same from under the horizontal extension thereof, as shown in Figure 1 by dash lines and by a solid line, respectively.
  • the box 6 for the supply of concrete is positioned beside the mold at a fixed height, and is connected to not-shown translation means, with its bottom being closed by a fixed plate 7 having one of its sides located at a short distance from the said mold.
  • this box lies under a charging hopper 8 which upon control delivers into the said box a proper amount of concrete M.
  • the plate 5 comes to be positioned under the mold 1, and the mold 1 is lowered and brought into contact with the said plate, which thus closes the mold cavities 2.
  • the box 6 is translated and positioned over the mold 1, to fill the mold cavities 2 with the material M. Attached to the upper side of the box perimeter are brushes 9 which during this step interfere with, and clean the underside of the countermold 3 male portions 4.
  • the mold is vibrated so as to cause the material M to properly and uniformly settle in the mold cavities 2.
  • the box 6 is returned into rest position, while leaving the mold cavities 2 filled with the material M.
  • the brushes 9 clean the countermold male portions 4.
  • the countermold is so controlled as to be lowered down and caused to perform its pressing action, while the vibrators acting upon the said countermold and on mold 1 are being actuated, whereby the material in the mold cavities 2 will be suitably compacted, so that blocks M′ having a high mechanical strength and same properties, are molded.
  • the countermold 3 is lowered down so as to directly or indirectly interfere with a limit stop means made, for example, as described hereunder.
  • reference B denotes the stationary frame of the machine, which by means of guides 10 supports the vertical rods 11 carrying the assembly of the countermold 3 and being at their top ends interconnected by a beam 12.
  • Shown at 13 is one of the hydraulic jacks which are, for example, mounted on the frame B, and which by acting on the countermold assembly or on the beam 12, vertically displace and press down as required the countermold 3.
  • two like vertical bolts 14 are fitted in beam 12, in a symmetric position relative to the rods 11, and the said bolts are slidable in respective fixed guides 15 (see also Figure 11) and are urged downwards by springs 16 holding the bolt heads 17 into abutment against the top ends of guides 15.
  • the bolts 14 project from the underside of beam 12 by a section of a length which is equal to, or is greater than the thickness of plate 5, the lower end of said bolts being provided with an enlarged portion or head 18.
  • a flat butterfly-like member 20 is mounted on beam 12 for rotation about a vertical shaft 19 located in an equidistant relation with the bolts 14; the said member is substantially set in contact with the lower face of said beam 12, and is of a thickness that is equal to, or is slightly greater than the thickness of the said plate 5, the said butterfly-like member 20 having the ends shaped as shown at 120, whereby it can be caused to hook the downwardly projecting section of bolts 14, between their enlarged heads 18 and the beam 12.
  • the shaft 19 In its section projecting from the upper side of beam 12, the shaft 19 is provided with a small lever arm 21 to which a double-acting hydraulic jack 22 is connected and has its body anchored at 23 to the said beam 12.
  • the butterfly-like member 20 On the jack being actuated, the butterfly-like member 20 is rotated and is caused to pass from the position shown by solid lines in Figure 12 to the position shown by dash lines, or vice-versa.
  • the butterfly-like member 20 When the countermold is so controlled as to be caused to perform its active molding stroke, the butterfly-like member 20 is located in its active position as in Figure 5. The descent of the countermold is stopped when the enlarged heads 18 of bolts 14 come to abut against end-of-stroke abutments 24 mounted on the top of frame B. By changing the height of these abutments, the thickness of the blocks molded in the mold 1 will be modified. When the stop condition as in Figure 5 is established, the feeding to the jacks 13 is discontinued, so that the countermold is stopped.
  • the jacks 13 are thereafter actuated to lower down the countermold ( Figure 7).
  • the countermold is stopped when the enlarged heads 18 of bolts 14 come to abut against the underside of beam 12.
  • the countermold 3 performs an extra stroke which is equal to the thickness of the butterfly-like member 20, and the molded blocks M′ are caused to get out from the lower side of the mold cavities 2, to such an extent that they are delicately laid on the ground S.
  • the machine is made ready for repeating a new operative cycle by being translated horizontally along the ground as in Figure 10, so as to have the mold 1 positioned over a clear area of the ground.
  • the illustrated solution for stopping twice the stroke of the countermold being lowered down merely has an illustrative purpose, so that the means by which such a dual stopping is achieved may be of a different construction, and may be differently arranged. It is, for example, not incompatible that a similar drawer-like-movable plate may be used in place of the butterfly-like member 20.
  • the means by which such a dual stopping is achieved instead of being located on the beam 12, may differently act on the guide rods 11 or on the platen carrying the countermold, or on other components.
  • the double-acting limit stop means mounted on the beam 12 may be otherwise mounted on the frame B in place of the abutments 24, which will then be placed on the said beam 12.
  • provisions may be made, once the blocks have been molded, for the mold and the countermold to be simultaneously lowered down with an extra stroke at least equal to the thickness of plate 5, so as to have the blocks laid on the ground. Then the mold is lifted up, while the countermold is being temporaneously kept stationary, until the condition shown in Figure 8 is established, so that once the blocks have been delivered from the mold, also the countermold will be lifted up and returned into its cycle-starting position.
