Definitions

  • An embodiment of such a matrix known from British Patent No. 888,636, consists of a solid plate with a flat side surface, constituting the base surface, in which cylindrical pins, which constitute the protrusions, are inserted driven fu-lly down into the bottom holes drilled into the plate to a depth, which in relation to the length of the pins determines the height of the protrusions over the base surface.
  • a solid plate with a flat side surface, constituting the base surface, in which cylindrical pins, which constitute the protrusions, are inserted driven fu-lly down into the bottom holes drilled into the plate to a depth, which in relation to the length of the pins determines the height of the protrusions over the base surface.
  • the matrix consists of a flat plate of perforated sheet metal stock material one side surface of which, herein referred to as the front-side, constitutes said base surface while the opposite side thereof is referred to as the rear-side, insertion pieces running through the plate through the perforations thereof and projecting over the front-side of the plate where they constitute the protrusions of the press surface, said insertion pieces projecting the rear-side of the plate all to equal height, where they are embedded in a layer of plastic adhering to the insertion pieces and the plate said layer covering the rear-side of the plate to the height of the insertion pieces over that side.
  • FIG. 1 illustrates a side view of a matrix according to the invention
  • FIG. 2 illustrates a fragment of the same matrix as seen from above or below in FIG. 1;
  • FIGS. 3 and 4 illustrate on a larger scale a detail from 3,400,655 Patented Sept. 10, 1968 FIGS. 1 and 2 in side view and seen from above respectively;
  • FIGS. 5, 6 and 7 illustrate also on a larger scale a cross section through the matrix according to FIGS. 1 and 2 along the line VIIVII each one in one of succeeding stages of manufacture;
  • FIGS. 8 and 9 illustrate a modification of a matrix according to FIGS. 1 and 2 respectively.
  • FIGS. 10 and 11 illustrate on a larger scale a detail of the same modification in side view as seen from the right or left in FIG. 10 respectively.
  • a plate 2a perforated with circular apertures 111 (FIG. 5) and the front-side 3 of which constitutes the base surface of the press surface, is provided with cylindrical pins 4a passing through said apertures.
  • the pins fit in the apertures without any special accuracy and by their projections over the base surface form the "protrusions of the base surface.
  • the matrix may be built up in a very simple way, for instance, in the following way.
  • the plate 2a is placed above a stop surface 8 at a distance from said surface corresponding to the desired height of the protrusions whereafter the pins 4a are allowed to fall or slide or are lightly pressed down through the holes 1a against the stop surface (FIGS. 3, 5 and 6).
  • the plastic layer 6 (FIG. 7) is" applied, which may be effected by any method known within that technique, for instance, by lamination with glass fibre reinforcement or by casting. When the plastic has hardened the matrix is finished.
  • FIGS. 8 and 9 illustrate as "an example a matrix in which a plate 2b perforated with rectangular slits 1b is combined with tooth shaped insertion pieces 4b (FIGS. 10 and 11), which may be made by cutting into pieces strip stock material of a size to fit the slits. In many such cases it is also possible to the same effect to use available key elements as insertion pieces.
  • the part of the insertion pieces with which they project over the base surface a shape independent of the shape of the remaining portion of the insertion pieces.
  • the shape of a head of arbitrary kind will increase the cost of the insertion pieces proper the advantage of using perforated plate for their securing nevertheless remains.
  • Press matrix With a press surface consisting of a fiat base surface provided with protrusions, comprising in combination a fiat plate of perforated plate stock material 4 one-sideof-whichconstituting the'base surface of the matrix, insertion pieces running through the perforations of said flat plate so as to project over said base surface and constituting said protrusions and also projecting over the opposite side of the plate all to equal height, and a layer of adhering plastic 'material covering said rear side to said equal height there embedding said insertion pieces.
