Feeder Provided with a Deformable Socket

Abstract

The invention relates to an insert to be inserted into a casting mold which is used for the casting of metals and has a casting cavity, having a body ( 3 ) which extends along a body longitudinal axis ( 7 ) and has a body cavity ( 6 ), the body ( 3 ) being constructed from at least one first shaped body ( 4 ), which has a connecting opening ( 10 ) by means of which the body cavity ( 6 ) can be connected to the casting cavity, and a second shaped body ( 5 ) which is placed onto the first shaped body ( 4 ), characterized in that the first shaped body ( 4 ) is embodied as an energy-absorbing device.

1 . An insert to be inserted into a casting cavity of a casting mold, which is used for the casting of metals, comprising a feeder insert, which extends along a feeder insert longitudinal axis, wherein the feeder insert comprises a feeder insert cavity, a first shaped body for connecting the feeder insert cavity to the casting cavity, and a second shaped body placed onto the first shaped body, wherein the first shaped body comprises an energy-absorbing device. 
   
   
       2 . The insert as claimed in  claim 1 , characterized in that the energy absorbing device comprises a deforming element. 
   
   
       3 . The insert as claimed in  claim 1 , characterized in that the second shaped body supported on the first shaped body. 
   
   
       4 . The insert as claimed in  claim 1 , characterized in that the first shaped body has a substantially tubular design. 
   
   
       5 . The insert as claimed in  claim 2 , characterized in that the deforming element comprises a bellows shaped component. 
   
   
       6 . The insert as claimed in  claim 5 , characterized in that the bellows shaped component comprises segments inclined at an angle of 0° to 80°, relative to the feeder insert longitudinal axis. 
   
   
       7 . The insert as claimed in  claim 6 , characterized in that the length of the segments between bends of the bellows shaped component is between 0.1 and 10% of an overall length of the bellows shaped component in the direction of the feeder insert longitudinal axis. 
   
   
       8 . The insert as claimed in  claim 5 , characterized in that the distance of the bellows shaped component in the direction of the feeder insert longitudinal axis is between 20 and 80% of the height of the first shaped body. 
   
   
       9 . The insert as claimed in  claim 1 , characterized in that the first shaped body is formed from an irreversibly deformable material. 
   
   
       10 . The insert as claimed in  claim 1 , characterized in that the first and second shaped bodies are formed as one piece. 
   
   
       11 . The insert as claimed in  claim 9 , characterized in that the deformable material is a metal. 
   
   
       12 . The insert as claimed in  claim 9 , characterized in that the deformable material is steel. 
   
   
       13 . The insert as claimed in  claim 12 , characterized in that the steel has a carbon content of more than 0.05% by weight. 
   
   
       14 . The insert as claimed in  claim 1 , characterized in that the first shaped body narrows in the direction of a connecting opening into the casting cavity of the casting mold. 
   
   
       15 . The insert as claimed in  claim 1 , characterized in that the first shaped body has an annular support face for supporting the second shaped body. 
   
   
       16 . The insert as claimed in  claim 1 , characterized in that the second shaped body has a centering recess for holding a centering mandrel. 
   
   
       17 . (canceled) 
   
   
       18 . The insert as claimed in  claim 1  characterized in that the first shaped body has a substantially bowl shape. 
   
   
       19 . The insert as claimed in  claim 5  characterized in that the bellows shaped component comprises segments inclined at an angle of 30° to 60° relative to the feeder insert longitudinal axis.
