Abstract
A mold table is linearly moved into a pouring position or a resting position in a vacuum casting unit and rotates around its vertical axis so that the ingot molds disposed on the mold table can be individually positioned in front of the pouring nose of a crucible. A flexible belt-type roller device, for example a roller chain 15 as used in the chain drive of a crawler, is guided around a rod-like carrier 13 disposed in direction F in the mold chamber, and a catch 16 is integrated into this flexible, belt-type device. A separate drive, preferably a rope drive, is provided for moving the apparatus 10, this drive being connected to the rotatable catch 16 generating the rotation of the mold table. All motors for linearly moving and rotating the mold table are disposed outside the vacuum chamber.
