Method And Device For Producing A Cast Workpiece

Abstract

A method and apparatus for producing a cast component with a wall in which at least one hollow chamber is formed. A hollow body for forming the hollow chamber is introduced into a casting tool by means of an apparatus, and liquid material is then supplied to the casting tool so as to surround the hollow body and thereby form the hollow chamber in the cast wall. For the assembly movement of the hollow body into the casting tool, the hollow body is received by a transporting device in which the hollow body is positively guided by its connection body areas.

         11 . A method for producing a cast component having a wall in which a predeterminately-contoured hollow chamber is defined using a hollow body having a contour complementary to the hollow chamber to be cast, comprising the steps of:
 introducing the hollow body into a casting tool by:
 receiving the hollow body by a transporting device, and 
 moving the hollow body from the transporting device to the casting tool; and 
   supplying liquid material to the casting tool so as to surround the moved hollow body and thereby define the predeterminately-contoured hollow chamber in the wall of the cast component;   wherein the hollow body has connection body areas for positively guiding the hollow body as it is moved from the transporting device to the casting tool.   
     
     
         12 . The method of  claim 11 , wherein in said moving step the hollow body is moved using the connection body areas from the transporting device into a takeover tool that forms a part of the casting tool. 
     
     
         13 . The method of  claim 11 , wherein in said receiving step the hollow body is pulled into the transporting device. 
     
     
         14 . The method of  claim 11 , wherein in said moving step the hollow body is moved out of the transporting device by operation of a pushing tool. 
     
     
         15 . Apparatus for use in producing, in a casting tool, a cast component having a wall in which a predeterminately-contoured hollow chamber is defined using a hollow body having a contour complementary to the hollow chamber to be cast, comprising:
 a transporting device for receiving the hollow body from an initial location to transport the hollow body to the casting tool, said transporting device being configured with guide surfaces for abutment with the hollow body for engagement of the hollow body by the receiving transporting device.   
     
     
         16 . The apparatus of  claim 15 , wherein the hollow body has at least one angled portion and wherein the guide surfaces have relief cuts that face one another and through which at least one angled portion of the hollow body can exit its engagement with the guide surfaces of the transporting device. 
     
     
         17 . The apparatus of  claim 15 , further comprising a takeover tool that forms a part of the casting tool for receiving the hollow body from the transporting device as the hollow body is transported to the casting tool, wherein the takeover tool includes a first positive engagement surface and the transporting device has at least one second positive engagement surface configured to compliment the first positive engagement surface of the takeover tool for cooperative engagement of the first and second positive engagement surfaces as the hollow body is transported from the transporting device to the casting tool. 
     
     
         18 . The apparatus of  claim 15 , further comprising a takeover tool that forms a part of the casting tool for receiving the hollow body from the transporting device as the hollow body is transported to the casting tool, wherein the hollow body has connection body areas for positively guiding the hollow body as it is moved from the transporting device to the casting tool, and wherein the takeover tool has a receiving profile for receiving the connection body areas of the hollow body. 
     
     
         19 . The apparatus of  claim 15 , further comprising a pushing tool for moving the hollow body from the transporting device to the casting tool, said pushing tool comprising a displaceable stop.
