Definitions

  • the present invention relates to the foundry technology and that a feeder cap, which encloses the space in which the material flows during the casting or rises, which serves to compensate for the occurring during the solidification of the casting volume shrinkage.
  • Such feeder caps as z. B. off WO 2003/043 781 A2 are known, consist of a ceramic or a ceramic base material with heat-insulating or exothermic properties and the enclosed in them casting material during the phase transition liquid ⁇ firmly in the casting as long as possible liquid, so as to allow a Nachf job ("Dichterpeisen”) and order to prevent a volume deficit ("voids") in the casting. The so physically caused volume deficit is transferred from the casting into the contents of the feeder cap.
  • the shape of the feeder caps is usually cylindrical and led out of the mold or embedded as blank feeder in the molding material.
  • the feeder bodies on a casting are generally removed from the molding material during the unpacking operation of the casting. This can be done by "natural" dropping or by breaking off the feeder body on a shaker hopper station. Depending on the organization of the processes, the separation can also take place in a separate operation, for. B. by knocking off, cutting, separating with separating wedge or the like. After completion of casting and gutting of the casting this is transported on what costly techniques and manual labor are necessary.
  • the object of the invention is to simplify this removal and further transport and to make manual work unnecessary (simplification of work / humanization of the working world);
  • the degree of automation and the degree of optimization of the work processes should be increased, potential sources of error by reducing manual activities should be avoided and the quality of the end product should be increased.
  • the coupling part of the transport device for easily automatable onward transport of the casting is available, for. B. in a monorail or robotic arm system, and the feeder body with its transport device is separated only in the last step from Gußwerk Western. In this way, all previous work operations from transfer of emptying take place automatically, u. a. further cooling, blasting, direct visual inspections or such by means of camera, hardness tests and final inspection. A discharge to perform smaller operations and manual intervention may be omitted.
  • the feeder cap 1 has a with her, z. B. by gluing, connected bottom 2 and a ceiling 3 with an opening, as they are used in commercial feeder caps for venting the mold during the casting process.
  • the feeder cap sits on the cavity for the casting 5 and encloses the space for the feeder body 4.
  • the casting 5 is surrounded by the molding material 7 and this of a mold frame 8 (or, for example, a mold).
  • An opening 9 in the bottom 2 has a tapered cross-section boundary, which has a notch at the junction between casting 5 and feeder body 4 result and favors the subsequent separation in the cleaning process.
  • the cap 1 includes a transport device 10 consisting of two or more armature arms 11 and a coupling part 12.
  • the latter is used to interact with a removal system with which the finished cast-casting is transported further, z. B. for further cooling and other required processing steps in the manufacturing process.
  • the coupling part is a simple hook; according to the circumstances of the onward transport system, it may take the form of an eyelet, a bow or a special molded part.
  • the armature arms 11 dip into the cavity for the feeder body 4 and extend substantially at or in the vicinity of the inner surface of the cap wall and the coupling member 12 protrudes through the opening of the cap cover 3 to the outside.
  • the armature arms 11 have recesses 13, in which the casting material penetrates during the casting process, so that a positive connection between the feeder body 4 and transport device 10 is formed.
  • the attachment of the transport device in the feeder cap can be done during their manufacture by molding, pressing and firing of the ceramic material, for. B. by shooting in the shaping.
  • the attachment can also be made non-positively after the production of the storage cap, z. B. by jamming or by gluing. This must be taken into account and adapted to the existing molding and manufacturing processes in the manufacture of the feeder caps.
