Definitions

  • the invention relates to a casting mold, comprising outer molded parts and mold cores inserted therein, which together form a mold cavity form.
  • the outer molded parts can be parts of a permanent mold and / or molded parts / outer cores.
  • the present invention has for its object a To provide casting mold of the type mentioned for complicated Castings can be used and in particular for rotary casting suitable is.
  • the inner cores are made of molded material are stacked in several layers and in a continuous Power flow between the outer molded parts and a final one Cover core made of molded material are clamped, the mold cavity of surfaces of the outer molded parts and surfaces of the inner cores and the cover core is formed.
  • This is according to the invention on other means to fix the molding cores in the outer mold cores and between the mold material cores with each other waived.
  • the construction in several layers allowed a complicated shape.
  • the use of the final Molded cover core allows a casting container to be docked (Contact casting) and thus creates the prerequisite for one Rotary casting process.
  • the cover core preferably has at least a gate and at least one gas outlet on.
  • the parts of the mold one base plate and several movable with respect to this include side panels.
  • the side parts in particular two opposite the base plate from the mold cavity include outwardly sliding longitudinal side parts and / or at least one opposite the base plate from the mold cavity Front part that can be swung outward.
  • the side parts can have molded projections on the inside that some of the inner cores also opposite the base plate hold tight.
  • This mold is first placed on the base plate stacked, then 180 ° around a horizontal axis rotated so that the cover core, which has a pouring opening, comes to lie down. Then on the cover core Pouring container that is filled with melt for a pouring operation is docked. When rotating again by 180 ° around the horizontal The melt flows in through the pouring opening in the core the mold cavity. The melt container is then removed and the casting solidifies, after which the Mold can be removed from the mold.
  • the mold is preferred each rotated about an axis parallel to their longitudinal extent.
  • the base plate is designed as a permanent molded part made of metal; the outer molded parts can also be permanent molded parts with the base plate are mechanically connected, or molded parts be with mechanical clamping devices from the sides and from together on the base plate and clamped.
  • a casting mold 11 comprises a multi-part base plate 12, side parts 13, 14, each as permanent molded parts, one A plurality of inner cores 15, which are stacked in several layers are built on the base plate 12, and a cover core 16, each consisting of molding material.
  • the multiple inner cores 15 are in a continuous flow of force between the base plate 12 and the cover core 16 clamped.
  • On the side parts 13, 14 form projections 17, 18 can be seen, the individual of the Hold the inner cores 15 against the base plate 12.
  • the Side parts 13, 14 are by actuating cylinders 19, 20 opposite the Base plate 12 can be moved in the opposite direction. Here they can be removed from each other in relation to the position shown.
  • the stacking structure of the inner cores 15 can then be opened the base plate 12. Then the side parts 13, 14, as indicated by opposite arrows, again lockable to reach the position shown again.
  • the cover core 16 is then placed on top. On the side parts 13, 14 bars 21, 22 are arranged, which are opposite to the mounting Side parts 13, 14 can be pushed back and after Placing the cover core 16 advanced into the position shown can be in which they cover the core 16 against the Hold inner cores 15 and the side parts 13, 14.
  • ejectors 23, 24 can be seen, which are used for demolding can be actuated by means of an actuating cylinder 25.
  • the base plate 12 and thus the entire mold 11 is horizontal Axis 27 lying perpendicular to the plane of the drawing. This applies in the same way 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 swivel arm 28 can be moved.
  • FIG. 2 the mold 11 with the column 27 and the casting container 29 shown rotated by 180 ° around the axis 26.
  • the casting tank 29 is still in the same position relative to the mold 11 as in Figure 1, but is now open at the top and is by means of a dosing spoon 31 just with melt 32 for one Pouring process filled.
  • the swivel arm 28 After filling the casting container 29, the swivel arm 28 is around 90 ° pivoted relative to the column 27 so that the casting container 29th comes to rest under the mold 11 in front of the column 27. Then is the casting tank 29 by means of the cylinder 30 against the Casting mold 11 lifted until the casting container 29 seals against the Cover core 16 abuts. In the position reached with it, the Casting mold 11 with docked casting container 29 in turn around the Axis 26 turned through 180 °. The one measured on the mold cavity Melt 32 flows through the gate 33 into the mold cavity, whereby gas from the gas outlet 34 into the casting container 29 can escape.
  • the casting container 29 with the Actuating cylinder 30 lifted from the mold 11 and by means of Swivel arm 28 rotated back into the position shown in Figure 1.
  • the demolding can be done by pulling back the side parts 13, 14 and actuation of the ejectors 23, 24 respectively.
  • the side parts 13, 14 could also consist of molding material, where instead of the latch 21, 22 then connected to the base plate Hold down.
