Core die with variable pins and process for producing a core

Abstract

A core die is provided. The core die includes a first half and a second half where a cavity is formed between the two. Pins are arranged on the halves and the pins are replaceable. By virtue of the modular inner structure of a core die, the core die may be matched to the desired changes of the core, by small changes, more quickly and more easily than would be the case if the core die had only one part or if the pins were a fixed component of the core die halves.

1 - 7 . (canceled) 
     
     
         8 . A core die, comprising:
 a first half; and   a second half,   wherein the first half and second half form a cavity in which a plurality of pins are arranged on the halves, and   wherein the plurality of pins are replaceable.   
     
     
         9 . The core die as claimed in  claim 8 ,
 wherein the replaceable plurality of pins are formed by an upper pin part and a lower pin part lying opposite the upper pin part.   
     
     
         10 . The core die as claimed in  claim 8 , wherein the upper pin part and the lower pin part are arranged only on an inner wall of the core die. 
     
     
         11 . The core die as claimed in  claim 10 , wherein the upper pin part and the lower pin part do not project through the first half or the second half. 
     
     
         12 . The core die as claimed in  claim 8 ,
 wherein the plurality of replaceable pins are fastened to a plurality of protuberances which are formed on the halves of the core die.   
     
     
         13 . The core die as claimed in  claim 8 , wherein the upper and lower pin parts make contact with one another. 
     
     
         14 . The core die as claimed in  claim 8 , wherein the plurality of pins completely bridge the cavity. 
     
     
         15 . A core die, consisting of:
 a first half; and   a second half,   wherein the first half and second half form a cavity in which a plurality of pins are arranged on the halves, and   wherein the plurality of pins are replaceable.   
     
     
         16 . The core die as claimed in  claim 15 ,
 wherein the replaceable plurality of pins are formed by an upper pin part and a lower pin part lying opposite the upper pin part.   
     
     
         17 . The core die as claimed in  claim 15 , wherein the upper pin part and the lower pin part are arranged only on an inner wall of the core die. 
     
     
         18 . The core die as claimed in  claim 17 , wherein the upper pin part and the lower pin part do not project through the first half or the second half. 
     
     
         19 . The core die as claimed in  claim 15 ,
 wherein the plurality of replaceable pins are fastened to a plurality of protuberances which are formed on the halves of the core die.   
     
     
         20 . The core die as claimed in  claim 15 , wherein the upper and lower pin parts make contact with one another. 
     
     
         21 . The core die as claimed in  claim 15 , wherein the plurality of pins completely bridge the cavity. 
     
     
         22 . A process for producing a core by means of a core die, comprising:
 providing the core die as claimed in  claim 8 ; and   varying an inner pin of the core die in at least one iteration in order to change the core.   
     
     
         23 . The process as claimed in  claim 22 ,
 wherein the replaceable plurality of pins are formed by an upper pin part and a lower pin part lying opposite the upper pin part.   
     
     
         24 . The process as claimed in  claim 22 , wherein the upper pin part and the lower pin part are arranged only on an inner wall of the core die. 
     
     
         25 . The process as claimed in  claim 24 , wherein the upper pin part and the lower pin part do not project through the first half or the second half. 
     
     
         26 . The process as claimed in  claim 22 ,
 wherein the plurality of replaceable pins are fastened to a plurality of protuberances which are formed on the halves of the core die.   
     
     
         27 . The process as claimed in  claim 22 , wherein the upper and lower pin parts make contact with one another.
