Definitions

  • the invention relates to a press plate with a press surface which is provided with a structure.
  • EP 2 060 658 A2 discloses a press plate which comprises a structured surface.
  • the structured surface includes a structure that has a mountain-like surface with valleys and heights.
  • the object of the invention is to provide an improved press plate which has a press surface provided with a structure.
  • a press plate having a structured press surface which has a structure with heights and valleys, and a rear surface opposite the press surface which has at least one elevation which is congruent in accordance with the heights, at least in part in accordance with the heights with the heights or at least part of the heights on the back surface.
  • the press plate is provided to produce structured material plates by means of the press surface, as is known in principle to the person skilled in the art.
  • the material plate includes e.g. a carrier, e.g. an MDF board or a particle board that is pressed with a resin or plastic-coated carrier (e.g. paper) using the press plate.
  • the material plate can also be a so-called luxury vinyl tile (LVT).
  • the press surface is structured, i.e. is provided with the structure so that the material plates produced have a structure corresponding to this structure.
  • the structure of the press surface can be removed, for example by means of etching or multiple etching, as is known, for example, from EP 2 060 658 A2.
  • the structure of the press surface can also be produced by a material-applying process.
  • the structure of the press surface includes the heights and the valleys.
  • the pressed surface of the pressed plate is pressed onto the workpiece to be machined in order to produce the material plates.
  • the rear surface of the press plate according to the invention opposite the press surface is not flat, as is the case with conventional press plates, but comprises at least one elevation. This at least one elevation runs according to the heights, at least corresponding to part of the heights opposite on the rear surface, and is therefore assigned to the heights, at least part of the heights.
  • the press plate has an increased material thickness on the back in the areas of the rear surface assigned to the heights.
  • the structure of the press surface of the press plate according to the invention can be pressed better into the material plate to be produced, since potentially higher pressure arises at the heights.
  • the resin can flow better into the relatively deep areas of the structure, since the temperature flow at the elevations is lower.
  • the heights are wide.
  • the width of the at least one elevation is preferably greater than or equal to the width of the heights.
  • the at least one elevation can in particular be designed in the form of a web.
  • the at least one elevation preferably has the same material as at least the majority of the remaining press plate, e.g. to ensure adequate thermal conductivity of the press plate according to the invention.
  • the heights have, for example, a height of at least 150 pm and / or a width of at least 5 mm.
  • the structure of the press surface preferably includes further heights.
  • the height of the heights are in particular significantly greater than the height of the further heights, preferably the height of the heights is at least twice as large as the height of the further heights.
  • the at least one elevation of the rear surface is assigned only to the heights, that is to say not to the further heights.
  • the rear surface preferably has the increased material thickness due to the elevation only in areas that are associated with the heights with the relatively large height.
  • the structure of the press surface can e.g. be assigned to a wood structure.
  • the heights represent e.g. represent relatively large branch structures, which are represented in the structure of the material plate as relatively deep valleys.
  • the heights can be arranged in a matrix on the press surface and limit partial areas of the press surface.
  • the sub-areas include structures that have the valleys and the further heights.
  • the at least one elevation is preferably designed in a matrix in accordance with the heights arranged in a matrix.
  • Tile structure is assigned and the heights arranged in a matrix, e.g. Joints in the material plate are intended to reproduce which bound individual reproduced tiles of the material plate that are assigned to the partial areas of the press surface.
  • the press surface is assigned to a parquet or board structure and that the heights arranged in a matrix are to reproduce, for example, joints in the material plate which delimit individual reproduced wood plates of the material plate that are assigned to the partial areas of the press surface.
  • the at least one elevation of the rear surface can be produced, for example, by a material-removing process.
  • the at least one elevation of the rear surface is or was produced by applying a mask with subsequent etching, in particular by multiple masking and etching and / or milling.
  • the at least one elevation can be produced, for example, by a material-applying process.
  • the at least one elevation can be produced by sintering, 3D printing, welding, soldering, masking and coating, and / or gluing.
  • 1 is a plan view of a pressed sheet metal with its pressing surface
  • Fig. 3 is a side view of the press plate in a sectional view
  • Fig. 4 is a perspective view of another press plate
  • Figures 1 and 2 show plan views of a press plate 1 and Fig. 3 shows a side view of the press plate 1 in a sectional view.
  • the press plate 1 comprises a press surface 2 shown in FIG. 1 and a rear surface 21 shown in FIG. 2, which lies opposite the press surface 2.
  • the press surface 1 is structured and comprises a structure with heights 3 and valleys 4.
  • the press plate 1 is provided for producing structured material plates by means of the press surface 2, as is known in principle to the person skilled in the art.
  • the rear surface 21 of the press plate 1 is also structured and, in the case of the present exemplary embodiment, comprises elevations 22 which, corresponding to the heights 3, run congruently with these on the rear surface 21.
  • the structure of the press surface 1 can e.g. by means of masking and etching or multiple masking and etching.
  • the structure of the press surface 1 can also be produced by a material-applying process.
  • the elevation 22 of the back surface 21 was e.g. produced by a material-removing process.
