Feeder Insert For A Vertically Split Casting Mold

Abstract

A feeder insert ( 10 ) for use in a vertically split casting mold that is used for the casting of metals includes a feeder body ( 11 ), which has an internal cavity ( 12 ) as feeder volume and which is composed of an exothermic and/or insulating material and which, in the base surface ( 17 ) thereof, which faces toward a pattern inserted into the casting mold during production of the casting mold, has a feeder opening ( 18 ) for connecting the cavity ( 12 ) to the mold cavity of the casting mold, wherein the feeder body ( 11 ) is oriented with its longitudinal axis ( 21 ), which runs through the feeder opening ( 18 ), at an angle with respect to the vertically oriented pattern and so as to be horizontal relative to the pattern, and the volume of the internal cavity ( 12 ) is of asymmetrical design with respect to an imaginary parting plane ( 25 ) running in or parallel to the longitudinal axis ( 21 ), characterized in that the feeder body ( 11 ) has an uneven mass distribution with respect to the parting plane ( 25 ), with a center of mass situated to one side of and spaced apart from the parting plane ( 25 ), and that region ( 28 ) of the internal cavity ( 12 ) of the feeder body ( 11 ) which is situated on that side of the parting plane ( 25 ) which is situated opposite the center of mass has a larger volume than that region ( 29 ) of the internal cavity ( 12 ) which is situated on that side of the parting plane ( 25 ) which faces toward the center of the mass.

1 - 7 . (canceled) 
     
     
         8 . A feeder insert ( 10 ) for use in a vertically split casting mold that is used for the casting of metals, comprising:
 a feeder body ( 11 ) having an internal cavity ( 12 ) as feeder volume, wherein said feeder body ( 11 ) is composed of an exothermic and/or insulating material, said feeder body ( 11 ) having a base surface ( 17 ). wherein said base surface ( 17 ) faces toward a vertically oriented pattern inserted into the casting mold during production of the casting mold, said base surface ( 17 ) having a feeder opening ( 18 ) for connecting the internal cavity ( 12 ) to a mold cavity of the casting mold, wherein the feeder body ( 11 ) has a longitudinal axis ( 21 ) running through the feeder opening ( 18 ) and is oriented with said longitudinal axis ( 21 ) at an angle with respect to the vertically oriented pattern and so as to be horizontal relative to the pattern,   wherein the volume of the internal cavity ( 12 ) is of asymmetrical design with respect to an imaginary parting plane ( 25 ) running in or parallel to the longitudinal axis ( 21 ),   wherein the feeder body ( 11 ) has an uneven mass distribution with respect to the parting plane ( 25 ), with a center of mass situated to one side of and spaced apart from the parting plane ( 25 ), and wherein a region ( 28 ) of the internal cavity ( 12 ) of the feeder body ( 11 ) that is situated on a side of the parting plane ( 25 ) which is situated opposite the center of mass has a larger volume than a further region ( 29 ) of the internal cavity ( 12 ) which is situated on a side of the parting plane ( 25 ) that faces toward the center of mass.   
     
     
         9 . The feeder insert according to  claim 8 , wherein the uneven mass distribution is realized by formation of different wall thicknesses on the feeder body ( 11 ), whereby the region ( 27 ) of the wall area ( 13 ) disposed beneath the parting plane ( 25 ) with a horizontal orientation of the feeder body ( 11 ) relative to the vertically oriented pattern has a greater wall thickness than the region ( 26 ) of the wall area ( 13 ) of the feeder body ( 11 ) disposed above the parting plane ( 25 ). 
     
     
         10 . The feeder insert according to  claim 8 , wherein the longitudinal axis ( 21 ) of the feeder opening ( 18 ) forms a central axis of the feeder body ( 11 ). 
     
     
         11 . The feeder insert according to  claim 8 , wherein the longitudinal axis ( 21 ) of the feeder opening ( 18 ) is arranged eccentric to a central axis of the feeder body ( 11 ). 
     
     
         12 . The feeder insert according to  claim 8 , wherein the feeder body ( 11 ) includes a cover region ( 14 ), wherein said cover region ( 14 ) is disposed opposite to the base surface ( 17 ) and includes an opening ( 22 ) that is aligned with the feeder opening ( 18 ) and disposed in the longitudinal axis ( 21 ) running through the feeder opening ( 18 ) for receiving a mold pin secured to the vertically oriented pattern inserted in the mold. 
     
     
         13 . The feeder insert according to  claim 8 , wherein the feeder body ( 11 ) comprises two halves ( 11   a ,  11   b ) divided along a transverse axis ( 23 ) running at a right angle to the longitudinal axis ( 21 ) of the feeder opening ( 18 ), wherein said two halves ( 11   a ,  11   b ) are assembled to form the feeder body ( 11 ). 
     
     
         14 . The feeder insert according to  claim 8 , further comprising a shaped part ( 30 ) having a through opening ( 31 ) that is aligned with the feeder opening ( 18 ) of the feeder body ( 11 ), wherein said shaped part ( 30 ) is fixed to the base surface ( 17 ) of the feeder body ( 11 ). 
     
     
         15 . The feeder insert according to  claim 14 , wherein the shaped part ( 30 ) is made of metal.
