Definitions

  • the invention relates to a method for manufacturing a mould for casting an edge around a panel, which method comprises the steps of:
  • a device with which an edge of plastic can be arranged on a panel.
  • a mould is first manufactured which can then be arranged around the panel, and whereafter a liquid material can be injected into the mould in order to arrange a plastic edge on the panel.
  • the mould has a substantially U- shaped cross-section, and arranged on either side at the position of the legs of the U-shaped cross-section are peripheral grooves in which a pressing ring is placed which distributes the pressure over the whole width of the groove and ensures that when the liquid material is injected the mould is properly sealed relative to the panel.
  • the mould is well positioned relative to the panel and that the pressing force is further adjusted such that a sufficient sealing action is present on the one hand and that the mould is not deformed by the pressing force on the other. This is because deformation will result in a deformation in the arranged edge.
  • the pressing force can be concentrated more on a smaller surface, whereby a greater sealing force between mould and panel becomes possible and wherein deformation of the mould takes place in a smaller area around the groove, thereby reducing the chance of deformation of the whole mould or a significant part thereof.
  • the step in the stepped rib is directed toward the shaped edge.
  • the sealing force is hereby applied as closely as possible to the transition between the panel and the edge, whereby a smooth transition between shaped edge and panel can be manufactured more easily.
  • the height distance from the step to the surface of the panel is substantially equal to the distance between the step and the transition between the panel and the shaped edge. Tests have shown that very good results are obtained with such a relation. This means that the mould can be rapidly positioned around the panel and that determining of the pressing force required to obtain satisfactory results can be done quickly.
  • the liquid material is flexible in cured state. The mould can hereby be placed easily round a panel.
  • the invention further comprises a method for arranging an edge around a panel, which method comprises the steps of:
  • the invention also comprises a mould, comprising an endless strand-like body of a substantially U-shaped cross- section, wherein at least one stepped peripheral groove is arranged at least on the outer side of the body at the position of the legs of the U-shaped cross-section.
  • a stepped peripheral groove is arranged on either side at the position of each leg of the U-shaped cross-section .
  • the figure shows a cross-sectional view of a device for manufacturing an edge round a panel.
  • Device 1 has an upper pressure plate 2 and a lower pressure plate 3 which are slidable relative to each other by means of guide pins 4.
  • Mould 5 Arranged between the two pressure plates 2, 3 is a flexible mould 5 which is subsequently placed around a panel 6.
  • Mould 5 has two injection openings 7 via which a liquid material can be injected into cavity 8.
  • Cavity 8 is formed by a substantially U-shaped cross-section having two legs 9, 10.
  • Panel 6 is centred relative to pressure plate 2 via dowels 11.
  • Each leg 9, 10 has a stepped groove 12, 13 in which a pressing ring 14, 15 is arranged.
  • Pressing ring 14, 15 transfers the pressing force of the respective pressure plate 2, 3 to the projection 16, 17 formed in stepped groove 12, 13.
  • This projection 16, 17 is arranged in stepped groove 12, 13 on the side close to the transition between cavity 8 and panel 6.
  • Pressure is hereby exerted on mould 5 as closely as possible to the transition between panel 6 and the edge to be formed, without deformation of the mould occurring and wherein a good seal results, whereby a smooth transition can be formed between panel 6 and the edge to be formed.
  • the height distance X from step 16, 17 to the surface of panel 6 is preferably substantially equal to the distance Y between step 16, 17 and the transition between panel 6 and the edge to be formed in cavity 8.

Abstract

Cette invention concerne un procédé de fabrication d'un moule permettant de couler un bord autour d'un panneau, lequel procédé comprend les étapes consistant: à utiliser un panneau pourvu d'un bord profilé; à disposer un logement autour du bord profilé; à remplir le logement d'un matériau liquide, lequel matériau durcit pour former un moule (5). Le moule ainsi obtenu se caractérise en ce qu'il comprend une rainure étagée (12, 13) s'étendant le long du bord dudit moule. Cette invention concerne également un procédé permettant de disposer un bord autour d'un panneau (6) et un moule.
