Method and Device for Making a Casting Mold Having at Least One Lateral Feeder System

Abstract

A method for making casting molds includes the steps of providing a casting model ( 10 ) that forms a mold cavity of the casting mold, and positioning at least one lateral feeder system ( 11 ) at the casting model ( 10 ) or mold cavity. The lateral feeder system ( 11 ) has a feeder ( 12 ) forming an inner feeder cavity ( 13 ) and a feeder cage ( 14 ) having a connecting channel ( 15 ) to the casting model ( 10 ) or the mold cavity. A frame ( 16 ) made from a heat-resistant material is mounted in the casting mold between an end of the connecting channel ( 15 ) on a casting model-side and the casting model ( 10 ) or the mold cavity, the frame ( 16 ) having a netlike web mounted and fixed therein. The netlike web is made of a fireproof material and has a through-hole.

We claim: 
     
         1 . A method for making casting molds, comprising:
 providing a casting model ( 10 ) that forms a mold cavity of the casting mold;   positioning at least one lateral feeder system ( 11 ) at the casting model ( 10 ) or mold cavity, wherein the lateral feeder system ( 11 ) has a feeder ( 12 ) forming an inner feeder cavity ( 13 ) and a feeder cage ( 14 ) having a connecting channel ( 15 ) to the casting model ( 10 ) or the mold cavity, wherein a primary axis of the connecting channel ( 15 ) runs at an angle to a primary axis of the feeder ( 12 );   mounting a frame ( 16 ) made from a heat-resistant material in the casting mold between an end of the connecting channel ( 15 ) on a casting model-side and the casting model ( 10 ) or the mold cavity, the frame ( 16 ) having a net-like web mounted and fixed therein, the netlike web comprising a fireproof material and having a through-hole.   
     
     
         2 . The method according to  claim 1 , further comprising commonly casting the frame ( 16 ) with the lateral feeder system ( 11 ) before forming the casting mold by molding of the casting model ( 10 ) on a model plate ( 19 ) supporting the casting model on which the casting model ( 10 ) is positioned and upon making of the casting mold commonly with the casting model ( 10 ) and the lateral feeder system ( 11 ). 
     
     
         3 . The method according to  claim 1 , in which upon making the casting mold by common casting of the casting model ( 10 ) with the lateral feeder system ( 11 ) positioned thereon, a recess is formed for subsequent insertion of the frame ( 16 ). 
     
     
         4 . The method according to  claim 1 , in which upon making of the casting mold by casting of the casting model ( 10 ) respective, a recess for subsequent insertion of the lateral feeder system ( 11 ) and frame ( 16 ) is formed. 
     
     
         5 . A frame with a netlike web made of a fireproof material and having a through-hold tensioned therein for performing the method of  claim 1 , wherein the frame ( 16 ) has a conical, tapered contour and wherein the netlike web is fixed to the tapered side of the frame ( 16 ). 
     
     
         6 . The frame according to  claim 5 , wherein the frame ( 16 ) comprises two partial frames ( 24 ,  26 ) oppositely moveable relative to one another, wherein the two partial frames ( 24 ,  26 ) are attachable to one another after application of a required tensioning of the netlike web. 
     
     
         7 . The frame according to  claim 5 , wherein the through-hold formed in the netlike web has smaller dimensions than a cross section of the connecting channel ( 15 ) formed in a feeder lower section ( 14 ). 
     
     
         8 . The frame according to  claim 5 , wherein the through-hold is disposed centrally in the frame ( 16 ) and based on the positioning of the frame ( 16 ), is positioned centrally in the connecting channel ( 15 ) of the feeder cage ( 14 ). 
     
     
         9 . The frame according to  claim 5 , wherein the frame ( 16 ) comprises a metallic material. 
     
     
         10 . The frame according to  claim 5 , wherein the frame ( 16 ) comprises a ceramic material. 
     
     
         11 . The frame according to  claim 5 , wherein the frame ( 16 ) comprises a fireproof material.
