  • Patent number: 6173757
    Abstract: A molding material is forced by a shooting device (3) into an openable tool (4) and solidified therein to a component of a mold (2)—a core or shell. The mold component (2) is removed when the tool (4) is open, and subsequently handled in any desired sequence, transported, and, if need be completed to a core assembly (1). The tools (4) are measured in a noncontacting manner in the region of the shooting device (3) and/or manipulators (5) and/or processing stations (6) and/or storage areas (7) and/or conveying paths (8), that the measured data are supplied to a computer (9), if need be, processed therein, and compared with stored desired values, and that the tools (4) are identified as defective, when a predeterminable or definable deviation from the desired values is detected.

  • Patent number: 5996681
    Abstract: A method and apparatus for controlling quality in a foundry having a plurality of core shooting machines which produce individual cores which are assembled to produce multi-part core assemblies which serve as foundry molds. The cores are removed from the shooting machines and at least selected cores are measured in a non-contacting manner. The measured data are then compared with stored desired values which may be determined by an analysis of an acceptable core, and any core having measured data which deviate from the stored desired values is rejected. Thus, the production of defective castings is avoided.

  • Patent number: 5458180
    Abstract: A storage hopper retains the mold core material and an outlet member is connected below the hopper for discharging the mold core material into the core shooting head. The outlet member is inserted into the core shooting head and is mounted on a vertically adjustable machine frame such that it may be inserted to various depths within the core shooting head and may also be removed. A shutoff device in the form of a rotating shutter closes the outlet member. A frame supports the outlet member and the storage hopper and vertically adjusts both for immersion within the core shooting head. A displacement measuring sensor detects the vertical position of the vertical adjustment members in relation to the machine frame. In the method the storage hopper is filled with mold core material, the outlet member is positioned over the core shooting head, and the outlet member is immersed within the core shooting head.
