Definitions

  • the present invention relates to a tool for molding concrete products with immediate mold release.
  • Such a tool comprising, on the one hand, a female tool comprising a frame inside which are arranged open cells on each side of the frame, means for fixing the frame to the press, and a certain number of cores. carried by bars fixed to the frame which extend in the plane of the frame in the vicinity of one of the open sides of the cells, and, on the other hand, a male part comprising a body and profiles made integral with one faces of the body by means of candles the dimensions of which are recessed relative to those of the profiles, the latter being dimensioned and mutually arranged so as to be able to penetrate together into all the openings remaining in the frame between the walls of the cells, cores and bars.
  • the partitions, certain surfaces of the longitudinal members, the bars and the cores are elements liable to wear out because they are exposed to friction from the concrete during molding.
  • the object of the invention is to propose a tool of the aforementioned type, in which wear elements are fixed to the frame in a removable and nevertheless precise manner.
  • the present invention thus relates to a female tool for molding concrete products for immediate demoulding, comprising a frame to which are attached a certain number of wear elements delimiting, inside the frame, open cells on each side of the frame , these wear elements comprising surfaces carried by the frame facing the cells, partitions separating the cells between them, and cores carried by bars arranged in the plane of the frame in the vicinity of one of the open sides of the cells and fixed at their ends to two opposite side members of the frame.
  • the tooling is characterized in that the wear elements comprise removable wear elements which, in the vicinity of each spar, are interposed between, on the one hand, a profiled bearing formed in a carried notch by the beam so as to overlap a base face of the beam and a face of the beam turned towards the inside of the frame, and, on the other hand, a face of a locking body forming part of a locking device comprising , in addition, means bearing on the frame to urge said face of the body in abutment capable of sliding against the removable wear element, so as to apply the latter against said bearing while allowing it to position itself freely.
  • the wear element is no longer permanently secured to the spar. On the contrary, by loosening the locking body, it can be extracted from between the seat and the body. However, in the service position, the wear element is precisely positioned against the bearing.
  • the wear element is correctly positioned and that, consequently, the product produced will have the desired profile.
  • the tool for molding concrete products comprises a female part 1 and a male part 2.
  • the female part 1 (FIGS. 1 to 12) comprises a generally rectangular frame 3 made up of two longitudinal members 4a and 4b extending along the lengths of the rectangle, and two cross-members 6 joining the ends of the longitudinal members two by two. sleepers 6 carry on their face directed towards the outside of the frame 3 ears 7 intended to be fixed to the press (not shown).
  • the female part 1 arranged in service along a horizontal plane, can be moved between a low position in which it rests on a board 8 (FIG. 1), and a high position in which it is, relative to the board 8, at a distance at least equal to the height of the side members 4a and 4b.
  • the board 8, which is mounted on rollers is locked against any displacement on the rollers.
  • the longitudinal members 4a and 4b, as well as the crosspieces 6, form, by their upper face opposite to the board 8, a flat and horizontal tabular surface 201 which, when loading concrete, supports a loading drawer constituted by an elongated hopper parallel to the direction of the side members and performing a back-and-forth movement above the frame in the direction perpendicular to the side members 4a and 4b.
  • the crosspieces 6 are made of cast steel with a U-shaped profile opening towards the outside of the frame.
  • the lower wing of the U is made up of the ears 7.
  • the outer face of the upper wing of the U is treated to resist abrasion and contributes to constituting the tabular surface 201. It carries a guide rib 202 to guide the loading drawer during its movement of va- back and forth above the frame.
  • the frame 3 has inside its wear elements delimiting cells 14 open on each side of the frame.
  • These wear elements include partitions 213 perpendicular to the plane of the frame and each extending from one spar to the other parallel to the crosspieces 6.
  • the wear elements also include the internal face 16 of the longitudinal members 4a, 4b which constitutes the end faces of the cells 14.
  • each of the cells 14 defined between the partitions 213 are mounted two rows of cores 41 arranged parallel to the crosspieces 6 and forming part of the wear elements.
  • the cores 41 are welded to a common strip 142 having a vertically elongated profile; the bars 142 are substantially adjacent to the plane of the tabular surface 201, on the side of the interior of the cells 14.
  • Each cell thus has in the plane of the tabular surface three comb-shaped openings between the faces 16, the partitions 213, the cores 41 and the bars 142.
  • the male tool 2 ( Figures 1 and 13), which cooperates with the cells 14 through these openings comprises a frame 249 to which are fixed by means of candles 254 profiles 252 dimensioned and mutually disposed so as to be able to penetrate together each in one of said openings.
  • Each profile 252 and an associated candle 254 are constituted by a one-piece foundry piece.
  • Each candle 254 is constituted by a rectangular fabric which in service is parallel to the partitions 213 and 247.
  • each assembly constituted by a profile 252 and a candle 254 is fixed to the body 249 by two screws 261.
  • the female tool 1 In the low position, the female tool 1 is closed below by the board, the cells 14 are filled with concrete by the loading drawer not shown, serving as a scraper by reciprocating movement on the tabular surface 201, so that the level of the concrete in the cells 14 is flush with said surface.
  • the female tool 1 is then subjected to vibrations aimed at carrying out a first compaction of the concrete.
  • the male tool 2 is lowered towards the female tool, the comb profiles of which penetrate into the cells 14 through the openings left free between bars 142, cores 41 and partitions 213 and 247.
  • the level of the concrete is substantially reduced to that of the underside of the bars 142.
  • the male tool 2 being held in this position, it is removed by lifting the female tool 1. After removal of the male tool 2, the board 8 is removed with the demolded products.
  • the ends of the bars 142 are fixed in notches 143 formed in each spar 4a or 4b so as to open both in the tabular surface 201 and in the internal wall 16 of each spar 4a or 4b (see Figures 1 to 4 , 19.20).
  • Each notch 143 (FIG. 19) has around its opening in the wall 16 facing the inside of the frame, a face 161 parallel to the tabular surface 201, and two opposite lateral faces 162 perpendicular to the face 161.

  • each notch 143 receives two ends belonging to two adjacent bars 142 and carrying the cores of the same cell 14. Each of these two ends is in the service position applied against the bearing associated with a respective one of the faces 162. Each end carries on its face turned towards the inside of the recess, that is to say towards the other end of the bar occupying the same notch, a bevel 166 whose obliquity is such that the faces oblique 168 of the corner 164 can be supported flat each on one of the bevels 167 when the two ends of the bar 142 are pressed flat against the faces 162.
  • the corner 164 is part of a locking device further comprising two tie rods 169 (which in the example described are bolts with a countersunk head in the large base of the trapezoid) which extend in a transverse direction to the plane of the frame 3 and are each threaded into a bore 171 of the corner 164 and a corresponding bore 172 formed through a fabric 231 which delimits the bottom of the notch 143 and which will be described later.
