Definitions

  • FIG. 2 shows a section of a negative mold 20 used to cast the chilled cast iron tile shown in FIG. 1 in a cross-sectional view.
  • the detail shown in Fig. 2 shows a concentric projection 22, which serves to form the recess 1 2 of the chilled cast iron tile 10.
  • the projection 22 protrudes from the rear wall R of the chill tile forming wall 24 of the negative mold 20 by a distance d.
  • the cylindrical side wall of the projection 22 is provided with a negative round thread 26, which serves to form the round thread 14 of the chilled cast iron tile 10.
  • zircon sand is used as the molding material having a grain size smaller than 0.2 mm in diameter.
  • this molding material it is possible to produce a sufficiently smooth surface during the casting of chilled casting for the formation of a screw-threadable thread without having to finish the negative casting mold 20 before casting. Dispensing with the finishing of the negative mold improves the reliability of the casting process, provided that the roughness of the surface of the casting remains within the tolerable range because of the casting of the casting Casting released gases can escape through the pores of the negative mold.
