Abstract
A die ejector comprises a chamber which can be subjected to vacuum and comprises a cover plate having a hole, a plurality of plates which are arranged in the interior of the chamber, protrude into the first hole and are jointly and also individually displaceable in a direction extending perpendicularly or in an oblique way in relation to the surface of the cover plate, and drive means in order to displace the plates. The drive means comprise a drive mechanism which comprises a motor and a pin which can be moved along a predetermined path and which is movable by the motor between two positions back and forth.

The path-like opening is different from plate to plate in such a way that the plates are displaced in a predetermined sequence in the mentioned direction when the pin is moved along the path.
