Definitions

  • This invention relates to a forming apparatus for bricks or the like.
  • Known brick forming apparatus disclosed for example in DE - A - 2245853 includes a mould for receiving brick forming material, a vertically reciprocable mould support arranged to support the mould, and upper and lower plungers adapted to compact therebetween the material within the mould.
  • the upper plunger may be driven by a hydraulic cylinder secured to an upper portion of the machine to press the brick material in the mould against a stationary lower plunger.
  • the mould support is typically driven by hydraulic cylinders mounted on right and left columns of the machine such that the mould is firmly supported while the brick is being pressed.
  • the present invention is characterised in that the mould support is provided with a sideways facing opening permitting lateral insertion or removal of an assembly of mould and plungers into or from said support.
  • the time required for changing moulds is reduced as compared with conventional brick forming machines and thus a higher efficiency in brick production is achieved.
  • a combination of mould and upper and lower plungers with particular dimensions can as an assembly be rapidly put into and withdrawn from the mould support thus enabling ready replacement of mould and plungers when the brick size is to be changed.
  • brick forming apparatus includes a metallic mould 1 which receives brick forming material.
  • the mould 1 is supported by a metallic mould support 4 which is reciprocable in a vertical direction and is driven by hydraulic cylinders 5.
  • a movable upper plunger 2 is driven via a pressing block 8 by hydraulic cylinders 9 mounted on an upper frame 6 of the machine via a pressing block 8 and is effective in operation to compact downwardly the material in the mould 1 against a stationary lower plunger 3.
  • the mould support and mould may then be pulled downwardly to the position shown in broken lines in Figures 1 and 2 to allow removal of the formed brick from the apparatus.
  • the mould support 4 includes two pairs of wedges 11 located in front of and behind the mould 1, the wedges being driven by hydraulic cylinders 10 to advance and retract. In the advanced position the wedges engage inclined surfaces formed on flanges 30 provided on the front and rear sides of the mould 1, and thus firmly secure the mould in place.
  • the mould 1 and the plungers 2, 3 form a detachable assembly which may conveniently as a whole be placed into and removed from the brick forming apparatus as described below, and this minimises the time delay involved in changing the mould 1, and plungers 2 and 3.
  • the mould support 4 is in the form of a square frame one side of which is open and thus is generally U-shaped as viewed from above.
  • the mould 1 and upper and lower plungers 2, 3 are assembled together prior to insertion into the apparatus and are placed into the mould support 4, via its front opening.
  • the flanges 30 of the mould 1 are above the support 4, and thus the mould 1, together with the plungers 2, 3, may be moved into the apparatus by means of a transfer truck 16 and into the mould support via the front opening thereof.
  • the mould support 4 is raised, the bottom flange of the mould support 4 will contact the flanges 30 of the mould 1 and thus the mould is seated snugly.
  • the transfer truck 16 has upwardly protruding pins 15, which fit into holes 14 on the underside of the mould 1 to position it correctly when on the truck.
  • the underside of the transfer truck 16 is provided with rollers 17, which roll back and forth on transfer rails 19 and positioning rails 7.
  • the transfer truck is also generally U-shaped as viewed from above and thus includes an open end end through which the lower plunger 3 passes when the assembly of mould and plungers is removed from or placed on the truck.
  • the assembly of mould 1 and the upper and lower plungers 2, 3 is replaced by moving the transfer truck 16 through the opening of the U-shaped mould support 4 such that the assembly is centred relative to the mould support 4; the transfer truck 16 is stopped at the correct position by a stopper 18 at the end of the positioning rails 7.
  • the mould support 4 is then raised by the hydraulic cylinders 5. As the mould support 4 moves upwardly engagement of the pins 12 with the holes 13 guides the flanges 30 of the mould 1 to position it correctly on the mould support 4. As the mould support 4 ascends further the mould 1 and the upper and lower plungers 2, 3 are lifted from the transfer truck 16, and the truck 16 may be moved to the left as shown in Fig. 2 out of the apparatus.
  • the mould 1 is secured to the support 4 by the advance of the hydraulic cylinders 10 and wedges 11, and the mould support 4 is then raised further such that the upper plunger 2 engages and may be for example bolted to the pressing block 8. Then the mould 4 is lowered until the bottom of the lower plunger hits the bottom face of the frame 6 to which the lower plunger may be secured by means of bolts or the like. This concludes the installation of a new assembly of mould and plungers.
  • the removal of the mould 1 from the apparatus follows the above steps in reverse order.

Abstract

Une machine de moulage pour briques ou autres produits semblables effectue le moulage en remplissant un moule de materiau brut et en moulant le materiau entre un piston superieur et un piston inferieur (2, 3) sur lesquelles s'applique une pression. Une embase de moule (4) presente une forme en U ouverte sur sa face avant. La machine de moulage est concue de telle sorte que lorsque le moule (1) est eleve sa section prise par un collier ne vienne pas faire obstacle a la section de l'embase de moule (4), permettant ainsi l'assemblage du moule (1) et des pistons superieur et inferieur (2, 3). L'ensemble peut avoir un mouvement libre telescopique au travers de l'ouverture de l'embase (4). Ainsi, la machine de moulage permet d'effectuer des changements de moule beaucoup plus rapidement et de maniere plus precise qu'avec la machine de moulage conventionnelle.

Claims (5)

1. Dispositif pour le formage de briques ou analogues comprenant un moule (1) destiné à recevoir la matière de formage des briques, un support (4) de moule pouvant effectuer un mouvement de va-et-vient agencé pour supporter le moule (1), des plongeurs supérieur et inférieur (2, 3) adaptés pour compacter entre eux la matière contenue dans le moule (1), caractérisé en ce que le support (4) de moule est muni d'une ouverture orientée latéralement et permettant une insertion ou un enlèvement par le côte de l'ensemble du moule (1) et des plongeurs (2, 3) dans ledit support (4) ou hors de ce dernier.
2. Dispositif selon la revendication 1, caractérisé en ce que le support de moule (4) a une forme générale en U.
3. Dispositif selon l'une des revendications 1 et 2, caractérisé en ce que ledit support de moule (4) est entraîné en va-et-vient au moyen de pistons et cylindres hydrauliques (5).
4. Dispositif selon l'une des revendications 1 à 3, caractérisé en ce que le support de moule (4) comprend en outre des cales hydraulique- ment manoeuvrables adaptées pour venir en appui sur le moule et le fixer.
5. Dispositif selon l'une des revendications précédentes caractérisé en ce qu'un ensemble de moule (1) et de plongeurs (2, 3) est transporté dans et hors du support de moule (4) au moyen d'un chariot (16) de transport monté sur rail.
