Coupling:
The pre-centered bolt is pushed into the coupling housing. A spring operated slide presses radially, moving the three-dimensional locking segments into the annular groove of the coupling bolt and creating a positive lock.

Release:
Pressure is introduced into the ring surface of the slide. This is then forced against the spring, allowing the segments to disengage from the annular groove. This ensures safe release of the lock, even under load.

Injection mould machines Reliable releasing, closing and locking of the locking bars guarantees a trouble free and safe porduction process shown as an example on a injection mould machine for plastic palletts. In this particular application an additional power stroke enables a safe locking even under high counterforces.
