  • the device according to the invention can preferably be in a Use the foundry system so that at least two of the invention Devices a furnace with a scoop are assigned and in linear motion between a casting station at the melting furnace and at least one solidification station can be moved back and forth. This takes place in the casting station preferably also the mold build-up and demolding instead, so that all handling organs are brought together here.
  • the Mold build-up and demolding can also be a separate one Station should be provided.
  • the casting plant is here with two Devices as a tandem and with three devices as a tridem system to designate, the latter being the reasonable maximum represents.
  • a melting furnace with the associated measuring spoon with at least two devices according to the invention are combined so that these are built up in a linear arrangement and the measuring spoon back and forth between them and the furnace is mobile. This simplifies the transport or Handling equipment.
  • a melting furnace with an associated measuring spoon with a plurality of devices according to the invention in a circular formation be built up that the measuring spoon between the melting furnace and the devices can be pivoted back and forth. This is at a larger number of devices cheaper than the linear Arrangement.
  • a device 11 comprises a bogie 12, which has a base plate 13 and two cheek parts 14, 15. In the cheek part 14 there is a shorter one in a bearing 16 Pivot 17 mounted. In the cheek part 15 is in a bearing 18th a longer pivot 19 is mounted. On the pivot 19 becomes a rotary drive 20 a. The two pivots are coaxial on a horizontal axis of rotation 21.
