Definitions

  • the invention relates to a method of processing a material, which is first of its solid state in a flowable state and then poured into a mold in which the material is then solidified. Furthermore, the invention relates to molds for carrying out the method and to articles which have been produced or produced by the processes and / or in such molds.
  • the bottom casting results in the most laminar mold filling, however, during the solidification process, the coldest material is in the mentioned feeder or riser, ie the storage space from which material is to be fed during solidification, so that here the make-up is ensured by larger feeder dimensions must become.
  • the side casting is relatively hot material in the feeder, however, results in a more turbulent mold filling than the bottom casting.
  • head casting is the hottest material in the riser or feeder, so that although a good make-up with the lowest feed volume, but the quality of the castings depending on the filling level deteriorated by turbulence.
  • the object of the present invention was to avoid the disadvantages of the previously known casting methods and to provide methods for processing materials which, with optimal laminar vortex-free mold filling and optimal Nachspeisung by the hottest metal from a storage room and thus smaller storage or feeder volume enable.
  • overheating of contour-related accumulations of material should be avoided and cycle, material, energy, transport and cutting performance should be saved.
  • the production of large-scale and complicated castings should be simplified and thus cheapened.
  • Another task aspect was the creation of appropriate casting molds for the rational and high quality production of castings.
  • the process for processing materials by introducing them into a flowable state and introducing them into a mold is first characterized in that the introduction into the mold takes place according to the principle of the bottom casting and the solidification according to the principle of the head casting.
  • it is first brought the material by heating in a flowable state and introduced into a mold or in the mold cavity or cavity according to the principle of the bottom casting and the solidification is carried out according to the principle of Kopfgusses / Kippgusses.
  • pivoting of the mold takes place about an axis which runs at least approximately parallel to the parting plane or to the parting plane of the mold.
  • the cavity and the run and thus also the parting line (s) or parting line (s) - level (s) are provided or arranged at an angle to each other. It may be either the casting run or the cavity run obliquely, but it can also be both cavity and run at an oblique angle to the horizontal, wherein the cavity and run to each other can include an obtuse angle. However, it is also possible for the cavity and / or the casting run to occupy a shallow angle to the horizontal.
  • cavity and run are provided at such an angle to each other and are pivoted together at such an angle and in such a direction that upon reaching a position of the storage space in which this the function of the riser or feeder can take over, the casting run has not reached the horizontal, it is particularly advantageous if the pivoting of the mold takes place in one direction, such that the casting run leads, so that in the solidification position of the run at least slightly upwards and a Leakage of the melt from the pantry, which then, as already mentioned, acts as a riser or feeder is not possible.
  • a development of the invention relates to a mold or mold, which has a reservoir below the cavity into which the pouring leads, wherein the area of the run leading into the Vorrafis container has a section - the inlet - which is lower than the reservoir.
  • the mold may further be characterized in that the cavity and the run are not provided parallel to each other, but at an angle to each other.
  • the mold or mold may be formed such that both, ie cavity and run, are inclined, wherein they can form an obtuse angle to each other.
  • the angle can be chosen such that upon pivoting of the mold into the position in which the storage space comes to lie over the cavity - the solidification position - and the storage space can act as a feeder or riser, the casting run in a the leakage of Melt from the storage space avoiding position by this at least slightly protrudes with respect to the horizontal, at least slightly upwards.
  • Such a design of the casting mold is advantageous in that the cavity and the casting run are arranged relative to one another and the shape is pivoted in such a way that the casting run leads.
  • the pivotable mold in which the mold halves surrounding both the casting run and the reservoir and the cavity are separated by corresponding parting lines, is expediently designed such that the pivoting takes place about an axis which extends at least approximately parallel to the plane of the parting plane ,
  • This mold is - with the reservoir down - filled according to the bottom casting principle with melt, the reservoir is located below the cavity and in the pivoted mold, the solidification of the melt - with the then acting as feeder or riser pantry upwards.
  • the casting mold has a closure on the pouring basin or a slide is provided in the region of the casting run, wherein the closure or slide is actuated before or in time during pivoting.
  • the invention also relates to castings which are produced by the inventive method and / or by means of the casting molds according to the invention, these castings in a particularly expedient and advantageous manner by gravity produced light metal, in particular aluminum alloys - exist.
  • FIGS. 1 to 4 conventional casting methods according to the prior art and the Figures 5 and 9 the casting method according to the invention.
  • FIGS. 1 to 4 is the indicated mold or mold respectively denoted by 1A, 1 B, 1C and 1 D and the mold cavity or the cavity with 1a -1d.
  • a feeder or riser 2a to 2d is provided, from which the so-called replenishment can take place when the casting solidifies.
  • the flow direction of the material is also determined by the contours of the casting, resulting in overheating areas in the mold, which cause defects in the casting.
  • the most laminar mold filling according to the side casting FIG. 2 a respect to the laminar mold filling already deteriorated design and both casting methods, ie bottom casting and side casting, have the disadvantage that the coldest material is located in the feeder or riser and thereby optimal solidification can only be done by larger feeders during solidification.
  • FIG. 7 is a position of the mold or mold 1 E shown after moving from the position of the FIG. 5 was pivoted about 90 °.
  • the parting line 10 between the two mold halves 1E 'and 1E can be seen and the pivot axis I, which runs parallel and through the plane formed by the parting lines 10.
  • FIG. 7 is still recognizable, the observer facing end face of the cavity 1e and the end face of the storage space 9 and the inlet 7a and the pouring basin 4e.
  • a closure 11 can also be provided or in the region of the inlet a slide 12, which are actuated in good time before or during pivoting, so that the casting run is completed there.
  • the pivoting can also be pivoted about a horizontal or horizontal or at least approximately parallel to the plane of the parting line 10 extending axis, for example, at least approximately to the axis extending perpendicular thereto III. It may be advantageous if the pivoting takes place in the direction of the arrow III ', so that the casting run or the pouring pond precedes and melt until it reaches a position with the reservoir 9 upwards at least this can not leak.
  • the pivoting can also take place about other axes or curves than the illustrated, for example, composed of the axes shown axes or curves; when using a shutter or slide, the direction of rotation is less critical with respect to the leakage of melt from the runner.
  • FIGS. 8 and 9 are cavity 20 and at least parts of the runner 21, namely the inlet 22, at an angle to each other, at an obtuse angle, arranged.
  • Cavity 20, the reservoir 25 and inlet 24 may be arranged to each other so that the inlet 24 is lower than the reservoir 25 and this in turn is lower than the cavity 20. In some cases, it may also be advantageous or sufficient if the inlet 24 is not placed below the storage space 25.
  • FIGS. 8 and 9 are cavity and inlet, as already mentioned, provided at an obtuse angle 26 to each other and both include each an angle 27, 28 a to a plane 29 which extends at least approximately perpendicular to the horizontal.
  • the mold 30 is pivoted in the in FIG. 9 shown position, and that about the axis 31, which is at least approximately parallel to the parting line 32 of the mold 30, and expediently in a pivoting direction of the arrow 33, so that the runner 21 with the Eingusteümpel 23 leads up to a position of the FIG. 9 , wherein the cavity 20 is brought into such a position that the storage space 25 is now above the cavity 20 and the storage space 25 can take over the function of a riser or feeder.
  • the pivoting is done so far that the inlet 22, the horizontal 34 has not quite reached, so it can leak no or little melt.
  • the method according to the invention or the casting molds according to the invention make it possible to cast according to the principle of bottom casting with a laminar mold filling that is optimal in comparison with the other casting methods and solidify according to the principle of head casting, which in turn results in the best possible make-up.
  • the invention further relates to castings which are produced by the method according to the invention and / or in the casting molds according to the invention.
  • the method according to the invention is particularly suitable for the processing of light metal, in particular light metal alloys, such as aluminum alloys, the invention is not limited to use in light metal alloys, but other materials according to the invention can also be processed, including non-metallic materials.
