Description of the automatic dispenser for cold chamber masohines

The invention for which a patent is pending is a device which is used to feed die casting machines, so-called cold chamber machines are used. By using this system, the die caster becomes the manual Activity decreased.

Systems of this type can be assumed to be known. The movement of the captured liquid Afetalles j from the furnace to die casting machine, however, is always divided in the already known devices sawn% in lifting and lowering movement and linear movements. The performance or the speeds of these systems are not very high due to the stopping in len points ler movement reversal and cannot keep pace with the rhythm of smaller casting machines.

The purpose of the invention is to create a device which is more efficient due to a favorable sequence of movements and can therefore also work in the cycle of smaller, high-speed die casting machines.

Up to 1 the device is in the rest position (dashed lines) drawn) and in the immersion position (fully marked). Figure 2 shows the position of the device on the machine to see (emptying).

By overlapping the movements, in addition to lifting and lowering movements, a linear movement is carried out at the same time , resulting in the high performance of the device. At the same time, the path from the furnace to the machine and back is smooth. An eccentrically mounted hollow body 2), which is rotatably attached to the lower part of the immersion trunk 3), is used to receive the metal from the furnace crucible 1).

The "immersion movement of the RUeaela 3), which Jurch one The impulse taken from the machine sequence of the die casting machine was triggered, an electrode control 4) braked it before the Badapiegela xirreiohen and brought to a standstill.

With the relatively high travel speed, no parts of the system are immersed in the metal bath.

One of the control electrodes 4) is used to dose the filling quantity. adjustable attached.

After the swiveling in of the receiving eccentric 2) liquid material has been picked up, the swiveling and driving movement is initiated. ■

The movement can, as shown in the drawing, about a hydraulic slewing drive Θ), a Hydraulic cylinder or electric motor are carried out.
