Definitions

  • the invention relates to a casting mold comprising Outside moldings and inserted therein molding cores, the together form a mold cavity.
  • the sweet moldings may be parts of a permanent casting mold and / or molded parts / outer cores be.
  • DE 195 31 551 A1 discloses a method for producing of castings of light metal and one for it provided lost form based on sand known.
  • a mold cavity for the casting depicting lost mold has mold outs, at least one core and a lid core with at least a feeder for at least one Druckmassel on.
  • Of the Lid core is treated with a core size and sealed on the surface.
  • the Druckmasseln With a pressure of up to about 1 bar applied. In this way, the quality of the improved casting and the volume of the Feeder material (Druckmassel) can be reduced.
  • those disclosed in DE 195 31 551 A1 Device and the corresponding method not for Rotomoulding suitable are those disclosed in DE 195 31 551 A1 Device and the corresponding method not for Rotomoulding suitable.
  • the present invention is based on the object to provide a casting mold for spin casting intended for complicated castings is usable.
  • the inventive solution for this consists in a Formed according to claim 1 mold.
  • According to the invention may refer to more funds for fixing the Molded cores in the outer mold cores and between the Molded cores are dispensed with each other.
  • Of the Building in multiple layers allows a complicated Shaping.
  • the use of the final cap core Made of molded material allows docking of a casting container (Contact casting) and creates in conjunction with the order of one horizontal axis rotatable suspension of the mold Prerequisite for a rotational molding.
  • the cover core points For this purpose, preferably at least one pouring opening and at least one gas outlet opening.
  • the side parts can in particular two opposite the Base plate from the mold cavity opposite to the outside wegschiebbare longitudinal side parts and / or at least one opposite the base plate from the mold cavity to the outside Include wegschwenkbares front side part.
  • the Side parts can hereby on the insides Form projections, the individual of the inner cores in addition to the base plate hold. to Determination of the cover core may be on the base plate or on at least two side parts slidable bars or be arranged pivoting claws, which are the package of Molded cores within the mold in a manner ensure that even when turning the mold shifts between the inner cores are excluded.
  • this mold is first on the Stacked base plate, then 180 ° around one rotated horizontal axis, so that the cover core, the one Has sprue, comes to lie down.
  • a casting container with Melt is filled for a casting process, docked.
  • the melt flows through the pouring opening in the cover core the mold cavity.
  • the melt container removed and it comes to the solidification of the casting, after which the mold can be removed from the mold.
  • the mold will preferably one at a time to their longitudinal extent rotated parallel axis.
  • the base plate is a permanent part made of metal educated; the outer moldings can also Permanent moldings that are mechanical with the base plate are connected, or molding material parts that are with mechanical clamping devices from the sides and from above the base plate together and clamped.
  • a casting mold 11 comprises a multi-part base plate 12, side parts 13, 14, each as permanent moldings, a plurality of inner cores 15, which in several layers one above the other on the Base plate 12 are constructed, and a cover core 16, each consisting of molding material.
  • the several inner cores 15 are in continuous power flow between the Base plate 12 and the cover core 16 clamped.
  • To the Side parts 13, 14 are mold projections 17, 18 can be seen, the single of the inner cores 15 in addition to the Hold base plate 12.
  • the side parts 13, 14 are through Actuating cylinder 19, 20 relative to the base plate 12th oppositely displaced. in this connection they are removable from each other in the position shown.
  • the stacking structure of the inner cores 15 on the base plate 12 done.
  • the cover core 16 is placed.
  • On the side parts 13, 14 bars 21, 22 are arranged, which are for mounting against the Side parts 13, 14 can be pushed back and after the Laying the cover core 16 advanced in the position shown can be in which they cover the core 16 against the Inner cores 15 and the side parts 13, 14 hold.
  • the demolding can be actuated by means of an actuating cylinder 25.
  • the base plate 12 and thus the entire mold 11 is a horizontal Rotatable perpendicular to the plane of the drawing axis 27. This applies equally to a column 27 on which a swivel arm 28 is mounted, which carries a casting container 29, which with a Actuating cylinder 30 parallel to the column 27 on the pivot arm 28th can be moved.
  • the finished mold 11 is in its position shown immediately after the stacking construction.
  • the casting container 29 hangs overhead, is about the actuating cylinder 30 of the Mold 11 is removed and by the pivot arm 28 on the column 27 pivoted by 90 ° relative to the mold.
  • the pivot arm 28 After filling the casting container 29, the pivot arm 28 is to 90 ° pivoted relative to the column 27, so that the casting container 29 under the mold 11 in front of the column 27 comes to rest. thereupon the casting container 29 by means of the cylinder 30 against the Mold 11 lifted until the casting container 29 sealingly on the Deck core 16 is present. In the position achieved with this is the Mold 11 with docked casting container 29 turn to the Axis 26 further rotated by 180 °.
  • the measured on the mold cavity Melt 32 flows through the sprue 33 into the mold cavity, wherein gas from the gas outlet 34 in the casting container 29 can escape.
  • the side parts 13, 14 could also consist of molding material, wherein instead of the latch 21, 22 then connected to the base plate Downers would occur.
