Definitions

  • the present invention relates to the use of a feeder insert with a volume center of gravity displaced relative to the opening axis of its passage opening in the production of a mold with a vertical division of form and a feeder insert attached to the mold for the feed of the mold cavity during the casting process. Furthermore, the invention relates to a method for producing a mold with vertical division of form and an attached to the mold feeder insert for feeding the mold cavity during the casting process. The invention also relates to corresponding molds and feeder inserts.
  • Single or multi-part feeder systems are used in large numbers and variety in the casting of metals in molds.
  • the feeder systems used also referred to as feeder, are largely surrounded by a molding material used to make the mold, such as foundry sand, and thereby held in position relative to the mold cavity of the mold.
  • Known feeders have a feeder cavity with a passageway for the liquid metal, whereby a connection between the mold cavity and the feeder cavity consists.
  • a subset of the metal filled in the mold cavity during the casting process enters thereby into the feeder and thus into the feeder cavity.
  • the liquid metal present in the feeder system should be able to flow back into the casting mold during the solidification process, which is associated with a contraction of the casting metal, in order to compensate for or compensate for the shrinkage of the casting up to the solidus temperature.
  • the metal which has reached the feeder insert is kept in the liquid state until the metal present in the interior of the casting mold has already solidified or already partially solidifies into the casting.
  • At least part of the feeder insert is therefore usually made of an insulating and / or exothermic material. Exothermic materials have the characteristic that they are ignited when entering liquid metal in the feeder cavity of the feeder insert, due to the prevailing temperatures. From this point, an exothermic reaction automatically occurs within the material of the feeder insert, so that heat energy is released to the metal in the feeder cavity over a certain period of time. Thus, the metal in the feeder system and in the transition region to the mold cavity of the mold is maintained in the liquid state.
  • the pivot plate In its vertical orientation, which corresponds to the working position of the pivot plate, the pivot plate is parallel to the plunger with the first half of the model, also referred to as a press plate, movable.
  • Press plate and pivot plate bound at least laterally a mold chamber into which the molding material is filled to form at least one mold half of a mold.
  • the filled molding material is then compacted by a relative movement of the pressure plate and the swivel plate and thus produces a mold half or a molded part.
  • An arranged on the model half on the pivot plate feeder system, which thus arranged in the mold chamber during the manufacture of the molding are, is included within the produced molded part.
  • Such feeder systems are aligned with their feeder longitudinal axis approximately perpendicular to the pivotable mold plate, so that the passage opening of the feeder insert during casting is approximately horizontal.
  • known feeder inserts also have a volume center of gravity offset relative to the passage opening, which is arranged during the casting process, in particular above the opening axis of the passage opening.
  • Feeder systems are known for use in making a divisible mold.
  • the disclosed arrangements comprise a mold plate and / or a mold model and further at least one feeder system with a feeder element and a feeder insert.
  • the feeder element and the feeder sleeve define the feeder cavity for receiving the liquid metal.
  • the feeder element has a first end, with which this is usually directly on the mold plate and / or the mold model in abutment or seated.
  • the feeder element has a passage opening with which the connection between the mold cavity of the mold and the feeder cavity of the feeder system is ensured. In this case, the passage opening is bounded by a side wall of the feeder element.
  • an arrangement and method for making molds in a metal casting molding machine which comprises a linearly adjustable plunger for forming a first model half and a pivotable mold plate for forming the second model half.
  • the molding machine further comprises a feeder system positioning means adapted to position a feeder system on the pivotable mold plate when it has reached its horizontal orientation during the ejection operation of a mold half used to make the molds.
  • the arranged on the pivot plate feeder system is thus during the compression process of the molding material within the mold chamber and is subject to the forces acting during the pressing process.
  • FIG EP 2 489 450 A1 the side wall around the passage opening formed deformable.
  • the sidewall is deformable such that there is a reduction in the distance between the first end of the feeder element and the second end the feeder element comes to which the feeder insert of the feeder system is attached via a mounting element on the feeder element. This results in a total reduction of the total height of the feeder system.
  • the side wall which serves as a footprint of the feeder system on the mold plate or the mold model, is also arranged offset to the center of gravity of the feeder cavity, so that upon compression of the molding material, a force acting in the direction of the opening axis of the passage opening generates a tilting moment in the area of the footprint.
  • the feeder system may tilt slightly so that the footprint at the first end of the feeder element rests unevenly on the mold plate or the mold model.
  • the invention has for its object to show a use of a feeder insert in the production of a mold and a method for producing a mold with vertical shape division, with which the production of a vertically divisible mold in a simplified manner while avoiding individual or all above described disadvantages is made possible.
  • the invention solves the underlying object by the use of a feeder insert with the features of claim 1.
  • the feeder insert is positioned in a prefabricated molding of the mold, that its opening axis extends below its center of gravity.
