Shield Feeder or Plug Feeder

Abstract

The invention relates to a feeder insert for inserting into a casting mold used for casting metals, comprising a feeder body 1 , which extends along a longitudinal axis 13 of the feeder and has a feeder cavity 2 , comprising a bottom side that can be inserted into the casting mold and a top side 7 that is situated opposite the bottom side. According to the invention, an energy absorbing device ( 8, 9 ) is provided on the top side 7 of the feeder body 1.

1 . A feeder insert for inserting into a casting mold used for casting metals, comprising a feeder body, which extends along a longitudinal axis of the feeder insert and comprises a feeder cavity, a bottom side in communication with the casting mold, and a top side that is situated opposite the bottom side, and an energy absorbing device provided on the top side of the feeder body. 
   
   
       2 . The feeder insert as claimed in  claim 1 , characterized in that the energy absorbing device covers at least the top side of the feeder body. 
   
   
       3 . The feeder insert as claimed in  claim 1 , characterized in that the energy absorbing device comprises a deformation element. 
   
   
       4 . The feeder insert as claimed in  claim 1 , characterized in that the energy absorbing device comprises an elastic element. 
   
   
       5 . The feeder insert as claimed in  claim 1 , characterized in that the energy absorbing device comprises a friction element. 
   
   
       6 . The feeder insert as claimed in  claim 1 , characterized in that the energy absorbing device comprises a plate-shaped element which is arranged generally perpendicular to the longitudinal axis of the feeder insert. 
   
   
       7 . The feeder insert as claimed in  claim 6 , characterized in that the plate-shaped element has at least one continuation element and the feeder body has at least one depression extending inward from the top side of the feeder body into which the continuation element is received. 
   
   
       8 . The feeder insert as claimed in  claim 7 , characterized in that the continuation element comprises a rod-shaped plug element and the depression comprises a sleeve. 
   
   
       9 . The feeder insert as claimed in  claim 8 , wherein ridges are that arranged along a wall of the sleeve such that their diameter within the sleeve decreases as they extend into the feeder body from the topside of the feeder body. 
   
   
       10 . The feeder insert as claimed in  claim 8 , wherein the sleeve further comprises a spring element which produces a counterforce when the rod-shaped plug element is inserted into the sleeve. 
   
   
       11 . The feeder insert as claimed in  claim 1 , characterized in that the energy absorbing device further comprises a skirt ( 11 ) which reaches around the upper circumference of the feeder body. 
   
   
       12 . The feeder insert as claimed in  claim 1 , wherein the feeder body further comprises a constriction on or near the bottom side of the feeder body to form a breaking edge. 
   
   
       13 . The feeder insert of  claim 6  wherein the plate shaped element extends outward at least to a maximum cross section of the feeder body. 
   
   
       14 . The feeder insert of  claim 9  wherein a diameter of the plug element is smaller than the diameter of the sleeve. 
   
   
       15 . A feeder insert for inserting into a casting mold used for casting metal comprising a feeder body which comprises a feeder cavity, a bottom side, a top side and an energy absorbing device introduced into one or more sleeves in the top side of the feeder body. 
   
   
       16 . The feeder insert as claimed in  claim 15 , characterized in that the energy absorbing device comprises a deformation element. 
   
   
       17 . The feeder insert as claimed in  claim 15  characterized in that the energy absorbing device comprises an elastic element. 
   
   
       18 . The feeder insert as claimed in  claim 15 , characterized in that the energy absorbing device comprises a friction element. 
   
   
       19 . The feeder insert as claimed in  claim 15 , wherein the sleeve further comprises a spring element which produces a counterforce when the energy absorbing device is inserted into the sleeve. 
   
   
       20 . The feeder insert as claimed in  claim 15 , wherein the feeder body further comprises a constriction on or near the bottom side of the feeder body which forms a breaking edge.
