Definitions

  • the present invention relates to a device for casting metal bodies, in particular by a chill casting process.
  • Chill casting devices are well known.
  • a mold delimits a mold cavity. Liquid metal is introduced into the mold cavity and hardens in the mold cavity. When removing the mold, the cured piece of metal is removed from the mold.
  • a permanent mold with two mold halves is often used, which is arranged in a vertical press.
  • the two halves of the mold are pressed together with the press.
  • the liquid metal melt is introduced into the mold from below at low pressure.
  • a press with a sliding table can be used for simple demolding.
  • the sliding table has a horizontally displaceable frame on which a mold half of the mold is arranged. To remove the mold, the other half of the mold is lifted and the frame is moved out of the area of the press so that the cast part can be easily removed.
  • a low pressure chill casting machine comprising a melting furnace and a stratified loading container, with a support column rotatable about its vertical axis being arranged between these two.
  • a support frame is attached to the support column and has a guide in which a bearing head is vertically displaceable.
  • the support column In the bearing head is a relative to a horizontal one the support column is mounted on the radial axis, pivotable T-shaped support frame.
  • Two holders are mounted on a crossbeam of the support frame. On the one hand, the holders can be displaced in a longitudinal axis of the crossbeam and, on the other hand, they can be pivoted about this longitudinal axis.
  • a support arm is mounted, to each of which one half of a mold is attached.
  • the support arms are rotatable about their own longitudinal axis and also pivotable about axes perpendicular to their axis of rotation and to the longitudinal axis of the holder.
  • the mold halves into any position and, moreover, to cast them in a parting plane.
  • it should be possible to remove a casting since the molds can be rotated in such a way that a casting spigot is directed forwards, which enables easy gripping using conventional pliers. Because the mold and also a riser pipe can be held by means of the device, it is possible that the sprue pin does not have to be torn off even if a parting line runs vertically.
  • a quick-change frame for die casting machines.
  • Such a quick-change frame comprises guide rails which are designed to be tiltable by 90 degrees relative to the horizontal. Furthermore, the quick-change frame can be removed from a tilting mold casting machine, so that after casting, another quick-change frame, in which a mold already heated to operating temperature is clamped, can be inserted into the guide rails that are still lowered.
  • the quick-change frame it should be possible to reduce the space required by a chill casting machine, since it is no longer necessary for an entire casting device to be tilted upwards.
  • faster processing should be possible through the use of several quick-change frames with appropriately preheated molds.
  • This low-pressure chill casting system comprises a first furnace and a second furnace as well as two handling units which are alternately assigned to the furnaces.
  • a station for unloading the cast parts and performing graphitization of the casting mold is provided between the furnaces. This station should make it possible to use the furnaces with independent operating pressures and metal fill levels.
  • the handling units are provided with a removal unit for removing the cast part, the removal unit being provided for moving the cast part towards an operator and for rotating the cast part about a horizontal axis.
  • a filling device comprises a furnace which has an electromagnetic pump in order to introduce liquid metal from the furnace via inlets into a corresponding cavity of a casting mold. It is provided that the casting mold is arranged in a frame that can be tilted about a pivot axis. In addition, a feed device connected to the casting mold via two channels is arranged in the frame. The feed device comprises a feed channel which can be connected to an electromagnetic pump of the filling device. In this way it should be possible, when filling a mold at low pressure by means of the electromagnetic pump, to raise and lower the mold or to tilt it during the filling process.
  • This device and this method thus relate to the inclination of a casting mold when filling a casting mold by means of an electromagnetic pump according to the low-pressure casting process.
  • This device is preferably designed for casting under pressure, in particular as a counter-pressure chill casting system or a low-pressure chill casting system.
  • the casting device comprises a lower hermetically sealable chamber and an upper hermetically sealable chamber, which are separated from one another by a platen.
  • a furnace is provided in the lower chamber, which has a crucible with melt.
  • a two-part casting mold is arranged in the upper chamber, which has a lower casting mold half and an upper casting mold half.
  • the crucible is connected to the casting mold via a riser pipe.
  • the upper mold half can be pivoted out of the device about a horizontal pivot axis.
  • a casting mold half is intended to be pivoted into a position after the permanent casting mold has been opened so that an inner surface of the casting mold half can be treated, preferably cleaned, smoothed and / or corrected by a person in a work-saving and time-saving manner. This is especially intended as preparation for a new casting cycle.
