Definitions

  • the present invention relates to a mold for molding stones or plates
  • Molds for producing stones or slabs from cement-bound material are known and are generally designed as multiple molds, with a large number of mold spaces which are delimited or defined by mold walls. Such molds also have other elements, such as mold dies, mold tables, cores, Core beams and other inserts All these elements form surfaces that come into contact with the concrete, i.e. surfaces that come into contact with the concrete or cement-bound material during the manufacture of the concrete blocks or slabs and in particular through the sand contained in the cement-bound material or also through additives such as expanded clay, brick split and Glass is subject to considerable abrasion.
  • Another disadvantage is that the steel used for the mold rubs off on the concrete blocks produced, which cannot be accepted, for example, in the production of sight stones. This effect occurs in particular if the mold in question is made from a very hard mold , rubbed off solid steel is made
  • the object of the present invention is to provide a mold for molding stones or plates which, with a long service life, also prevents the material of the mold from rubbing off on the stones or plates produced
  • the mold according to the invention for molding stones or plates has at least one mold space defined by elements of the mold.
  • the elements defining the molding space are at least partially made of a non-metallic, abrasion-resistant material on their surfaces facing the molding space.
  • surfaces facing the molding space are understood to mean all surfaces that come into contact with the material from which the stones or slabs are formed during the molding process. So e.g. Molded blocks made of concrete, the "surfaces facing the molding space” are “surfaces in contact with concrete”.
  • the shape according to the invention can have any geometry.
  • the geometry of the form is determined by the desired geometry of the stones or plates produced with the form, and by the necessary adaptation of the form to the machine used to produce the stones and plates.
  • the core can also have a different shape and size, since the geometry of the stones or slabs to be produced can also vary within a wide range.
  • An embodiment is preferred according to which the elements of the mold defining the at least one mold space are mold walls.
  • the elements defining the mold space further comprise at least one core and / or a stamp.
  • the core is held by a core carrier, and the core carrier can be attached at any point of the core.
  • the core can thus be introduced into the mold space from any direction, ie from above, from below or from one of the sides of the mold.
  • the stamps of the form which are fastened to a common stamping plate by means of holding or spacing elements, can also be moved in any direction, that is to say both raised or lowered vertically and moved horizontally in any direction. Any direction of movement is possible, since the holding or spacing elements can be attached to the stamp at any point.
  • the molding space preferably has a plurality of cores, with the aid of which corresponding recesses in the shaped stones or slabs are formed.
  • the elements defining the mold space are provided with a coating or cladding made of the non-metallic, abrasion-resistant material on at least part of the surfaces facing the mold space.
  • the cladding is interchangeable.
  • At least some of the elements defining the at least one mold space are made of the non-metallic, abrasion-resistant material.
  • the cladding or coating made of the non-metallic, abrasion-resistant material is advantageously provided or fastened on a supporting part of the respective element, for example made of metal, preferably of steel.
  • the elements of the mold provided with the coating or cladding interchangeably or to design the cladding in such a way that they can be replaced if necessary.
  • the covering or coating is provided on interchangeable insert parts of the mold.
  • individual or all interchangeable elements can then be arranged in a freely floating manner in order to further reduce abrasion or wear on the surfaces of the mold facing the mold space.
  • the surfaces of the individual components of the mold to be covered or coated are designed so that the non-metallic, abrasion-resistant material forming the coating can be sprayed, glued, vulcanized, screwed, clamped, fastened and / or riveted onto the surfaces of the components. Therefore, embodiments are preferred according to which the cladding or coating is glued, vulcanized, screwed, clamped, wedged and / or riveted onto the respective carrier element.
  • the molds according to the invention can be used for the production of stones and slabs, in particular for the production of brick and chimney stones.
  • the molding space therefore has a size which corresponds to the size of the usual masonry or chimney stones.
  • Particularly preferred are molds whose mold space has a length of 6 cm to 100 cm, a width of 6 cm to 40 cm and a height of 6 cm to 40 cm, in particular a length of 10 cm to 30 cm, a width of 10 cm up to 20 cm and a height of 10 cm to 20 cm.
  • the abrasion-resistant material from which the elements defining the molding space are made in whole or in part or from which the abrasion-resistant covering or coating is made is a material from the group consisting of rubber, plastic, ceramic, ceramic composite material, glass, porcelain, silicon carbide, glass fiber reinforced Material, carbon fiber reinforced material or mixtures thereof are used.
  • the abrasion-resistant material from which the surfaces of the elements defining the molding space facing the molding space are made can be adapted to the material from which the molding compound is made.
  • plastic is very suitable for forming stones or slabs from concrete.
  • a mold according to the present invention can be used for the production of stones or slabs, in particular for the production of bricks and chimneys from a variety of materials.
  • Materials from which the stones or slabs can be formed are, for example, mineral mixtures, inorganic materials, cement, lime, concrete, cement-bound materials, plastic or their mixtures. Description of the drawing
  • FIG. 1 shows a form for producing concrete blocks in a simplified perspective partial representation.
  • FIG. 1 and generally designated 1 there consists, among other things, of: from the outer mold walls 2 and 3, which are perpendicular to one another in the illustrated embodiment and limit the shape of the mold 1, and from several inner mold walls 4, of which only one is shown in the figure for the sake of simplicity and which shows the shape in FIG subdivide a large number of individual shapes or mold spaces 5, so that a large number of concrete blocks or slabs can be produced in a known manner in one work step.
  • a stamp which among other things. serves to compact the concrete introduced into the respective molding space 5. At least one such stamp 6 is provided for each molding space 5. Also shown in the figure is a core 7, which is held at its upper end on a core carrier 8 and extends into the molding space 5. Each molding space 5 preferably has a plurality of such cores 7, specifically for the production of concrete blocks with corresponding recesses.
  • stamps 6 of the form 1 are attached via holding or spacing elements 6 'to a common stamp plate, not shown, with which the stamps 6 can be raised and lowered in the vertical direction.
  • the aforementioned elements of form 1, namely the mold walls 2-4, the punches 6, the cores 7 and the associated core supports 8 are made of steel.
  • the punches 6 and the cores 7 on their surfaces which delimit the respective mold space 5 (surfaces facing the mold space) by abrasion during molding, and also a discoloration
  • the mold walls 2-4 are on their Surfaces delimiting mold spaces, but also on the surfaces adjoining them, for example on the upper and lower end faces, the punches 6 on their surfaces facing the mold spaces 5 and also on adjoining lateral surfaces, and the cores 7 on all of them, reaching into the mold spaces 5
  • surfaces with a cladding or coating of an abrasion-resistant material 9 as shown for the mold walls 2 - 3, for the stamp 6 and for the core 7.
  • plastic is preferably used as the material for the abrasion
  • FIG. 1 thus reflects a particularly preferred embodiment of the present invention: a mold for molding masonry and chimney blocks made of concrete, the surfaces of the mold facing the molding space having an exchangeable plastic cladding.
