Definitions

  • Such a press tool is known from EU patent 0 043 019.
  • the filling of the material to be pressed takes place with the help of gravity. Due to the relatively small filling slots, the filling process is relatively slow. In the case of parts with steep, with vertical and / or with relief walls, there is a risk that the filling process will be interrupted, but at least is uneven, because the effect of gravity is partially canceled out by frictional forces acting on the product.
  • channels 15 are connected via a channel 16 and channels 17 to an annular channel 18 which can be pressurized with a pressure medium. Additional branch lines can be seen at 19 and 20.
  • the stamp 11 is also covered with a rubber cover 21, behind which channels 22 open, which can be fed by a central channel 23. The stamp 11 can thus be pressurized from the outside, which allows the molded plate to be easily detached from the stamp 11 or its rubber cover 21 when the stamps 10 and 11 are moved apart again.
  • the space between the punches 10 and 11 is filled with the aid of a funnel 24 which can be placed on a filling part 25 of an annular part 27.
  • This filler part 25 is shown in more detail in FIG. 2. It covers the space which is indicated in FIG. 3 by 25 'and is a segment-like insert body in the annular part 27. used.
