Definitions

  • the sintering material may be compressed, either before or during the sintering, so as to increase the density of the sintered die product, Furthermore, a heat-resistant parting agent may be coated on the surface of the charged sintering powder except at the portions covered by the pattern, and additional sintering powder may be placed thereover, so that the resulting product after sintering is a split metal mold consisting of an upper portion and a lower portion having a molding surface therebetween corresponding to the surface of the pattern.
  • a further object of the invention is to provide a method for producing a die or mold having high strength.
  • FIG. 8 is a transverse section taken along the line VIII-VIII of FIG. 7;
  • the second embodiment of the invention concerns the manufacture solely of the lower die 21 of the first embodiment.
  • the method of the present invention can be applied not only to the manufacture of press die and casting molds, but also to diecasting molds, molds for plastic, glass or rubber molding, as well as other general metal molds. It is likewise apparent that by proper use of parting compounds or infiltrant metal sheets arranged on the surfaces as desired, it is possible by means of the present invention to make various types of multi-split molds such as a triple or quadruple split mold.
