Casting mold having beveled end faces on inner walls

Abstract

A casting mold for producing a hollow component having apertures and inner walls is provided, in which the casting mold has at least one inner wall element having apertures, into which liquid metal can also propagate, wherein at least one inner wall element has an end face in the region of the aperture, which end face is beveled and which runs at an angle differing from 90° to a propagation direction of the liquid metal or of side surfaces of the inner wall elements in the casting mold. Accordingly, the propagation front of liquid material in the casting mould is influenced by a specific modification of the end faces of inner wall elements and influences or the formation of oxide layers are displaced to less critical regions of the casting portal to be produced.

1 . A casting mold for producing a hollow component having apertures and inner walls, in which the casting mold has
 at least one inner wall element having apertures, into which liquid metal can also propagate,   wherein at least one inner wall element has an end face in the region of the aperture, which end face is beveled and which runs at an angle differing from 90° to a propagation direction of the liquid metal or of side surfaces of the inner wall elements in the casting mold.   
     
     
         2 . The casting mold as claimed in  claim 1 ,
 wherein the end face is at an angle of 45° to 60° to the propagation direction of the liquid metal or to the side surfaces of the inner wall elements.   
     
     
         3 . The casting mold as claimed in  claim 1 ,
 wherein the casting mold has a plurality of inner wall elements,   wherein a plurality of inner wall elements have a bevel of the end faces, the end faces beveled in particular in each case to the same side.   
     
     
         4 . The casting mold as claimed in  claim 3 , wherein all beveled end faces are beveled to the same side. 
     
     
         5 . The casting mold as claimed in  claim 1 ,
 wherein the propagation direction of the molten metal runs at least in places parallel to the inner wall elements.   
     
     
         6 . The casting mold as claimed in  claim 1 ,
 wherein those end faces of the inner wall elements which lie opposite the beveled end faces of the inner wall elements are not beveled.   
     
     
         7 . The casting mold as claimed in  claim 1 ,
 wherein the casting mold is made of ceramic.   
     
     
         8 . The casting mold as claimed in  claim 1 ,
 wherein the beveled end faces are formed at the site where a molten metal propagates first.
