Definitions

  • the invention relates to a method for producing a cast wheel, wherein a core remaining in the casting wheel, which has a circumferential rim, is inserted into a casting tool having at least one lower mold part and one upper mold part, which are moved relative to each other for closing the casting mold, wherein the Core is positioned by means of at least one positioning element in a predetermined position in the casting mold, wherein an end portion of the positioning is frictionally locked in the circumferential ring of the core.
  • the invention further relates to a casting tool for producing a cast workpiece, in particular a cast wheel, with at least one lower molded part and one upper molded part, which are movable relative to each other for closing the casting tool.
  • a method for producing a wheel-cast rim in which a preformed metal foam core part is inserted into a casting tool which has a mold top part, a mold bottom part and lateral core slides.

  • the casting tool or the positioning element has a ventilation opening.
  • the remaining in the casting wheel positioning are fixed to the core.
  • the positioning elements with the movable mold upper part enter into a self-clamping connection.
  • the positioning element has a conical lateral surface, which causes the self-clamping effect by abutment on a shoulder forming a cross-sectional constriction in the vent opening of the mold upper part.
  • This technique has proven to be particularly useful to keep the core part with positioning in the predetermined position, when the positioning can be attached to ribs of the core member, which protrude from an annular outer part radially inwardly.
  • the projecting in the axial direction of the ribs positioning can be clamped in the appropriate vent opening of Kokillenoberteils.

  • the core is positioned under the action of gravity without contact with the mold parts of the casting tool.
  • the holder of the core is thus carried out in particular on the weight of the core, so that a stable support on the support surface is achieved. Accordingly, it is not necessary to provide a clamping connection between the positioning element and the associated molded part of the casting tool for centering the core.
  • the positioning is placed on a respect to its operating position horizontally arranged bearing surface;
  • the positioning element is clamped when closing the casting tool between the support surface of the lower mold part and a corresponding contact surface of the upper mold part.
  • the core is first placed on the support surface of the lower mold part before the mold parts are moved towards each other for closing the casting tool, wherein the positioning element between the corresponding contact surfaces of the casting tool is clamped.
  • the core is secured against slipping during the casting process, so that the core is arranged with high accuracy in the desired position in the finished casting workpiece.

  • the other end region of the positioning element is preferably fixed in the core in a friction-locked and / or force-locking manner.
  • the shape of the end region projecting from the core determines the contact surface with the bearing surface of the lower molding.
  • a comparatively small contact surface is provided;
  • the contact between the positioning element and the support surface can be increased by means of the plate-shaped end region.
  • a cast workpiece is formed, which encloses the particular circular encircling ring.
  • This method is particularly useful for producing a cast wheel, in which the core is arranged substantially completely in a circumferential rim flange.
  • the ring has in particular radially inwardly projecting pockets, which may optionally extend into the spokes of the cast wheel.
  • the cast workpiece is painted or powdered at least in the region of the cut end of the positioning.
  • the entire cast workpiece is finally painted to eliminate the risk of corrosion as much as possible.
  • the object underlying the invention is achieved in that the lower mold part has a circular encircling elevation with a support surface on which a free end portion of a connected to a circumferential ring of a core positioning element can be placed so that the core can be positioned without contact with the moldings in the casting mold. Accordingly, the same advantages can be achieved with the casting tool according to the invention as with the described method, so that in order to avoid repetition reference is made to the above statements.
