Abstract
The invention relates to an arrangement for a fluid-driven lock cylinder for the actuation of moving parts such as slides, cores and corresponding units on press tools and injection moulding tools for metal or plastic materials. A piston is accommodated in a displaceable fashion in a piston cylinder. A divided ring forms an end stop for the piston. The stop ring exhibits a maximum diameter which exceeds the diameter of the piston. An inclined external axial part of the stop ring forms a stop for making contact with a counter-pressure part of the piston cylinder. The counter-pressure part is inclined to a degree corresponding to the inclination of the end stop on the stop ring.

Arrangement (1) for a fluid-driven (2, 21) lock cylinder (3) for the actuation of moving parts (4) such as slides, cores and corresponding units on press tools and injection moulding tools (5) for metal or plastic materials, comprising:
- a piston (6) accommodated in a displaceable fashion in a piston cylinder (7), in conjunction with which a divided ring (8) forms an end stop for the piston (6), characterized in that the stop ring (8) exhibits a maximum diameter (D), which exceeds the diameter (d) of the piston (6), and in that an inclined external axial part (9) of the stop ring (8) forms a stop for making contact with a counter-pressure part (10) of the piston cylinder (7), in conjunction with which the counter-pressure part (10) is inclined to a degree corresponding to the inclination of the end stop (9) on the stop ring (8);
- the ring (8) is formed by at least two segment-forming ring parts (8A, 8B), which are held together at mutually touching end parts (8A-8n) and are guided in a direction towards (11) and away from (12) one another by means of a guide pin (13).
