Definitions

  • the invention relates to a casting process for producing a casting with a mold and a casting plant for carrying out the casting process.
  • the invention has for its object to provide a casting, can be realized with the short cycle times and has a high process reliability. Another object of the invention is to provide a casting plant for carrying out the method.
  • the mold is rotatably mounted in this method about a rotation axis about which the common rotational movement is performed. Characterized in that mold and container are rotated together for introducing the melt into the container, castings of high quality can be achieved.
  • the amount of melt which serves not for the production of the casting, but for Steiger and the like., Can be kept low, so that the amount of metal to be re-melt and feed the material cycle is low. The process can be carried out with high cycle times.
  • the melt is transported in the container to the mold.
  • a method is for example from the EP 1 155 763 A1 known .
  • the casting method according to the invention provides that the mold is moved after filling the melt to be cast in the container on the container. A movement of the container with the melt can be avoided.
  • the mold can be moved very quickly over the container despite its high weight of several tons, so that high cycle times are feasible.
  • the container is not moved during the movement of the mold over the container. It is envisaged that the mold will be moved in a combined translational and rotational movement over the container.
  • a combined translational and rotational movement can be realized in a simple manner with a single drive, so that the method can be carried out with a casting machine with only one drive for the mold.
  • the combined translational and rotational movement allows movement of the mold on the container with a component of motion perpendicular to the plane between the container and the mold.
  • the mold and the container are rotated together by at least 180 °.
  • a largely emptying of the container can be ensured in the mold.
  • an advantageous filling of the mold is achieved.
  • the mold and the container are rotated together about a horizontal axis of rotation.
  • the mold and the container simultaneously carry out a translatory movement during the common rotation.
  • container and mold perform only a common rotational movement and that after the common rotation container and mold are separated. Subsequently, the mold can perform a translational movement.
  • the container is expediently held movably on at least one arm in at least one direction of movement.
  • the container is decoupled from the at least one arm before the common rotation of container and mold and coupled to the at least one arm after the common rotation.
  • the container By independent of the mold movement of the container, the container can be pivoted away from the mold, so that there is a good accessibility of the mold. Characterized in that the arm is decoupled from the container before mold and container are rotated together, the common rotation can be performed unhindered. For the arm so no additional degrees of freedom are necessary.
  • the container is pivotally supported on the arm about an axis of rotation.
  • the container may also be held on several, in particular on two arms. However, it can also be provided that the container is held on one side to an arm and that the container is supported in the filled state on the opposite side. The support takes place in particular with respect to a frame of the casting plant.
  • a casting plant with which the casting process can be performed, has a mold, which is pivotally mounted about a first axis of rotation and a container which is pivotally mounted about a second axis of rotation.
  • the mold is mounted in addition to the pivotability about the first axis of rotation in a second direction of movement movable.
  • the movable mounting of the mold in a second direction of movement allows the mold to be moved over the container.
  • the second direction of movement may be a pivotability about a second axis of rotation or a translational movement.
  • the second direction of movement makes it possible to move the mold over the filled container while the container remains immobile. As a result, spilling over of the liquid melt in the container is avoided.
  • the second direction of movement of the mold also makes it possible to fill the container with melt during the insertion of at least one core into the mold.
  • the second direction of movement is advantageously a longitudinal direction.
  • the mold can perform in addition to the rotational movement a translational movement.
  • the longitudinal direction is inclined to the horizontal. Due to the inclination of the longitudinal direction, the mold can be placed from above onto the container.
  • the rotational movement of the mold is coupled to the movement in the longitudinal direction. This makes it possible to move the mold with only one drive in the longitudinal direction and about the axis of rotation, so that there is a simple structure of a casting plant for performing the casting process.
  • the second direction of movement is a pivoting movement about a second axis of rotation.
  • a pivoting movement can be structurally comparatively easy to implement.
  • the pivoting movement can be with a corresponding arrangement of the second axis of rotation, a placement of the mold on the container from above.
  • the mold is driven by a planetary gear, which forms in particular the last stage of a multi-stage transmission.
  • the drive of the mold via a planetary gear allows a very large translation, so that a sufficiently large drive torque for the movement of the mold can be generated. This is necessary because of the large weight of the mold of several tons.
  • a planetary gear with multiple planet gears it is possible to make the storage of the mold very safe. This can be achieved by designing each planetary gear so that it can move the weight of the mold alone. As a result, the safety factor is multiplied by the number of planetary gears.
  • a large ratio is achieved when the mold is firmly connected to the outer ring of the planetary gear.
  • a coupling of the translatory and the rotational movement can be achieved in that a firmly connected to the moving outer ring of the planetary gear wheel, in particular a gear, rolls on a running in the longitudinal direction, stationary rack.
  • a rotation of the outer ring of the planetary gear thus causes both a pivoting movement of the mold around the axis of rotation of the outer ring of the planetary gear as well as a rolling of the outer ring of the planetary gear on the rack and thus a movement of the mold in the longitudinal direction.
  • the movement of the mold in the longitudinal direction can be adapted to the rotational movement.
  • both the first axis of rotation of the mold and the second axis of rotation of the container are horizontal.
  • the mold and / or the container has means for tolerance compensation between the superimposed upon the common rotation sealing surfaces of the mold and container. As a result, it can be ensured that mold and container bear tightly against each other during the common rotation.
  • the mold has a holder with a closed frame on which the mold is fixed.
  • the frame is in particular formed in one piece.
  • the mold has a mold cavity.
  • the closed frame extends in a plane which is parallel to the first axis of rotation of the mold and which intersects the mold cavity.
  • the mold has an actual mold, which is formed of metal and has a large weight.
  • the center of gravity of the mold is therefore usually at the height of the mold cavity.
  • the frame is as close to the center of gravity, so that there are short distances and thus short lever arms. This allows the construction to be carried out with low weight and high stability.
  • the mold has a filling opening, on which the container can be fixed via at least one clamping element.
  • at least one actuation for a clamping element is arranged on the underside of the mold facing away from the filling opening.
  • the thermal load is very high, while set at the bottom of the mold lower temperatures.
  • the arrangement on the underside the operations can be arranged in a less thermally stressed area. This increases the durability of the operations.
  • the mold has at least one movably mounted cover element, wherein the movement of at least one tensioning element is coupled to the movement of at least one cover element.
  • a lid member may for example be a flap or a slider which fixes one or more cores in the mold, so that slipping or falling out of the cores is prevented when rotating the mold.
  • both the cover element at the filling opening is arranged by a coupled movement and the clamping element in the region of the filling opening pivoted, so that only a small adjusting movement is necessary for the final fixation of the container.
