Definitions

  • the invention relates to a method for producing foundry sand molds, in which a metered amount of molding sand is compacted above a model within a temporarily closed space.
  • the invention also relates to an apparatus for performing the method.
  • the molding sand is compressed from the back of the mold or from the upper edge of the molding box to the model and to the parting plane of the model. In addition to a long compression path and high compression work, this has the disadvantage of often unsatisfactory compression.
  • the invention has for its object to provide a method and an apparatus for the production of foundry sand molds, in which an optimal hardness of shape is achieved on the model contour with little compaction work.
  • the object is achieved according to the invention by the features mentioned in claims 1 to 7.
  • FIGS. 1 to 6 show in FIGS. 1 to 6 a molding machine according to the invention in its various positions.
  • the molding machine consists essentially of a lifting cylinder 1, on which there is a model carrier 2, which is able to accommodate various model plates 3 with models 4, a fixed and immovable mold space 5, a displaceable dosing hopper 6 and a likewise displaceable press head 7. Finally, the Forming machine still a sand knife 8, through which the finished bale is cut to a certain size. A mold box 9 is used to hold the mold bale.
  • the model plate 3 is equipped with an elevation 10 arranged at its edge, through which a circumferential chamfer is formed on the mold. This avoids the formation of a sand ridge during pressing in the mold space, which would have a negative effect on the mold division. 1 shows the basic or rest position of the molding machine.
  • the dosing hopper 6 filled with molding sand is located above the molding space 5, in which it dispenses a certain amount of molding sand. It is possible to sieve the molding sand or fill it up with aerators. The molding sand now acts on the model 4, which is moved into the molding space 5 by means of the press cylinder 1.
  • the press head 7 travels over the mold space 5 filled with sand.
  • the press head can also be provided with a water cushion or be designed as a multi-die press head. The molding sand is compacted by suddenly raising the press cylinder 1 against the press head 7.
  • the dosing hopper 6 and the press head 7 return to their basic position. 4 shows this. Then the press cylinder 1 presses the compressed form into one predetermined position where the bale of shape is cut to a certain size by means of the sand knife 8. The sand knife 8 is followed by the molding box 9, which is placed on the molding space 5 and the compacted mold bale.
  • the mold bale is pushed into the mold box 9 by a further upward movement of the lifting cylinder 1 and clamped by the latter.
  • the shaped bale is picked up by a transfer unit.
  • the press cylinder 1 is then pulled out of the mold space 5. As shown in FIG. 6, the molding machine is now in its basic position again. The molding box 9 can now be lifted up.
