Abstract

The device according to the invention serves to retain a blow mould segment in the region of a blow moulding station which is provided with a support element for the blow mould segment. The blow mould segment can be detachably fixed in the region of the support element by at least one locking element. The locking element is designed so as to provide both positively locking retention and non-positively locking retention of the blow mould segment.

Claims

1. A device for mounting a blow mold segment in a blowing station, which is provided with a support element for the blow mold segment and in which the blow mold segment can be detachably held in place in the vicinity of the support element by at least one locking element, wherein the locking element (43) is designed to hold the blow mold segment in place with both positive locking and frictional locking.

2. A device in accordance with claim 1, wherein the locking element (43) holds the blow mold segment (42) in place with at least two locking clips (63).

3. A device in accordance with claim 1, wherein the locking clips (63) are rigidly connected with each other by a common base element (45).

4. A device in accordance with claim 1, wherein the locking element (43) comprises the base element (45) together with a positioning element (44).

5. A device in accordance with claim 1, wherein the base element (45) and the guide element (46) are connected with each other with play by at least one connecting element (62).

6. A device in accordance with claim 1, wherein the connecting element (62) is designed as a projection that fits into a guide slot (68).

7. A device in accordance with claim 6, wherein the connecting element (62) is designed as a pin.

8. A device in accordance with claim 1, wherein the guide slot (68) has an essentially L-shaped configuration.

9. A device in accordance with claim 1, wherein the base element (45) and the positioning element (44) are supported on at least one common guide element (46).

10. A device in accordance with claim 1, wherein the positioning element (44) has a slot (65) by which it is supported on the guide element (46).

11. A device in accordance with claim 1, wherein the base element (45) has a diagonal slot (66) by which it is supported on the guide element (46) and that the longitudinal direction of the diagonal slot (66) is arranged obliquely to a longitudinal axis (67) of the positioning element (44).

12. A device in accordance with claim 1, wherein the locking element (63) can be positioned by a lever (50).

13. A device in accordance with claim 12, wherein the lever (50) is mounted as a rocker arm.

14. A device in accordance with claim 12, wherein the lever (50) is designed to be separable from the locking element (43).

15. A device in accordance with claim 1, wherein the lever (50) passes through an opening (55) in the positioning element (44) and has an end piece (56) by which it is supported in a recess (57) of the support element (41).

16. A device in accordance with claim 1, wherein the base element (45) and the positioning element (44) can be tensioned relative to each other by at least one spring (53).

17. A device in accordance with claim 1, wherein the locking element (43) can be fixed in place in its unlocked state by at least one catch.

18. A device in accordance with claim 1, wherein the positioning element (44) is mounted in a way that allows it to be tensioned relative to the base element (45) by at least one wedge-shaped surface (51).

19. A device in accordance with claim 1, wherein the blow mold segment (42) is designed as an inner shell of the mold and the support element (41) is designed as an outer shell of the mold.

20. A device in accordance with claim 1, wherein the blow mold segment (42) and the support element (41) are connected with each other in two regions on opposite sides of each other and that the first of the two connections is formed by the locking element (43) and the second of the two connections is formed by at least one rigidly mounted clamping clip (69).

21. A blowing station for blow molding containers made of a thermoplastic material, which blowing station has at least one blow mold segment, wherein the blow mold segment is mounted by a device in accordance with claim 1.

22. A blow-molding machine with at least one blowing station, which has at least one blow mold segment, wherein the blow mold segment is mounted by a device in accordance with claim 1.
