Definitions

  • the invention relates to a mold having inside walls with end faces which are chamfered.
  • Molds for making hollow components with internal structures such as turbine blades, often have multiple channels in which liquid material propagates.
  • an oxide layer often forms in this region, because in this intermediate region two liquid fronts collide, which then form an oxide film layer in this thin region.
  • the object is achieved by a casting mold according to claim 1.
  • FIG. 1 shows a mold 1 'according to the prior art.
  • a propagation direction of a liquid metal, which is introduced into the mold 1 'or the longitudinal direction of outer 4', 4 '' and inner 7 ', 7' 'wall elements of the mold 1' is designated by the reference numeral 19.
  • the propagation direction 19 runs almost parallel to the walls 4 ', 4 ", 7', 7" (FIG. Fig. 1, 2 ); 103 ', 103 ", 106', 106" ( Fig. 3 ).
  • the mold 1 ' accordinging to the prior art, in the direction of propagation 19 of the molten liquid to be infiltrated viewed opposite the inner wall elements 7', 7 ", wherein between the outer wall elements 4 ', 4" of the mold 1' in the mold 1 ' solidified metal walls 2 ', 2' 'of a cast component results.
  • the inner wall elements 7 ', 7 “have an opening 13' for two incoming liquid fronts 22 ', 22", into which 13' the liquid metal penetrates and thus forms an inner structure 25 ', ie a connection between the walls 2', 2 "of the later cast component.
  • An end face 10 'of the inner wall element 7' and an end face 10 "of the opposite inner wall element 7" are formed perpendicular to the propagation direction 19.
  • FIG. 2 shows a mold 1 according to the invention, in which compared to FIG. 1 an end face 40 of an inner wall element 31 (analogous to 7 ') is designed differently.
  • the end face 40 is chamfered and extends at an angle different from 90 ° to the direction of propagation 19 or to the outer surface 50 of the inner wall element 31.
  • the end face 40 of the inner wall elements 7 ", 31 is bevelled, that of the liquid front 22 ', 22". is first rinsed.
  • the liquid front 34, 37 of the liquid material is influenced and an inventive opening 43, in which the two liquid fronts 34, 37 meet, moves with its contact line 60, away from the bevelled end face 40 and away from a breakthrough 43 between the end faces 10 ", 40 of the inner wall elements 7 '', 31 in a mechanically less critical area, so that a casting with walls 54 ', 54" is formed, which has a higher strength.
  • An inner wall 55 is formed between the inner wall elements 103 ', 106', 103 ", 106" when the metal solidifies.
  • End faces 109 ', 109 "of the wall elements 103', 103", which lie opposite the beveled end faces 112 ', 112 ", are preferably not beveled but extend perpendicularly to the propagation direction 19 or to the side surfaces 51 ', 51''.
  • the angle of the chamfered end faces 40, 112 ', 112' 'to the propagation direction 19 may preferably be between 45 ° and 60 °.
  • the entire end face 40, 112 ', 112' ' is chamfered.
