Abstract

An assembly appliance for mould tool parts of an injection moulding tool is disclosed, the assembly appliance including an assembly plate configured for insertion into an injection moulding machine and including a tool carrier for receiving first mould tool parts to be assembled; and an assembly frame having a guide system for a translatory displacement of the assembly plate along a longitudinal extension of the assembly frame, and a support device for stationary support of a second mould tool part which corresponds to at least one of the first mould tool parts.

First claim

The invention claimed is:

1. An assembly appliance for mould tool parts of an injection moulding tool, the assembly appliance comprising:
an assembly plate;
an assembly frame with an upper side;
the assembly plate includes a tool carrier for receiving first mould tool parts to be assembled, the assembly plate being configured for insertion into an injection moulding machine;
a displacement plate, the assembly plate being rotatably mounted on the displacement plate; and
the assembly frame having a support device for stationary support of a second mould tool part which corresponds to at least one of the first mould tool parts,
wherein for a translatory displacement of the displacement plate along a longitudinal extension of the assembly frame for displacement of the assembly plate relative to the second mould tool part a guide system is arranged on the upper side of the assembly frame, the guide system includes two guide rails which run parallel to one another and onto which the displacement plate is mounted.

2. An assembly appliance according to claim 1 , wherein the assembly frame comprises:
a lower side facing away from the assembly plate; and
support elements configured to a machine bed of the injection moulding machine and being assembled on longitudinal sides of the assembly frame on its lower side.

3. An assembly appliance according to claim 1 , wherein the assembly frame on a longitudinal end comprises:
a face side configured for releasable connection to a fixed mould clamping plate of an injection moulding machine.

4. An assembly appliance according to claim 1 , wherein the guide system of the assembly frame comprises:
an adjustment appliance for the assembly plate.

5. An assembly appliance according to claim 1 , wherein the assembly plate is assembled on a rotation unit which passes through the displacement plate and is rotatable about a rotation axis which runs perpendicular to an upper side of the displacement plate.

6. An assembly appliance according to claim 5 , wherein the rotation unit is a multi-pole electric motor which comprises:
a stator and a rotor, the motor being a torque motor with an internal rotor construction manner, wherein the rotor is connected to the assembly plate in a rotationally fixed manner.

7. An assembly appliance according to claim 6 , comprising:
a first absolute sensor, configured as a rotation angle sensor for monitoring rotation movement of the electric motor.

8. An assembly appliance according to claim 4 , wherein the support device for the second mould tool part is a carrier slide which is supported on the guide rails, and the assembly plate and a connection device are arranged on the assembly frame, the assembly plate being translatorily displaceable with respect to a stationary mould clamping plate of an injection moulding machine.

9. An assembly appliance according to claim 1 , wherein the adjustment appliance for translatorily displaceable displacement of the assembly plate is a linear motor.

10. An assembly appliance according to claim 9 , comprising:
a second absolute sensor for monitoring translatory displacement of the displacement plate.

11. An assembly appliance according to claim 6 , wherein the torque motor is of an internal rotor construction manner and comprises:
a rotor configured as a hollow cylinder and which includes a centrally arranged feed-through for supply conduits/leads for media and electrical energy, as well as for control leads.

12. An assembly appliance according to claim 11 , comprising:
at least one pair of first supply conduits for feed and discharge of cooling water;
at least one pair of second supply conduits for feed and discharge of hydraulic oil;
at least one supply conduit for compressed air;
at least one supply lead for electrical energy; and
at least one control lead.

13. An assembly appliance according to claim 11 , wherein the feed-through is a rotation feed-through.

14. An injection moulding tool comprising:
a first mould tool part; and
at least one second mould tool part, wherein a closed state of the first and at least one second mould tool parts delimit at least one mould cavity, wherein the at least one second mould tool part is assembled on a stationary mould clamping plate of an injection moulding machine, wherein the first mould tool part is assembled on a tool carrier which is assembled on an assembly plate and the at least one second mould tool part is assembled on a support device of an assembly appliance according to claim 1 .

15. An injection moulding tool according to claim 14 , wherein the tool carrier is configured in a prismatic manner and is configured to be rotatable in a predefined manner about a rotation axis which runs perpendicular to a displacement plane.

16. An injection moulding tool according to claim 15 , wherein the tool carrier comprises:
at least 4 side surfaces which run parallel to the rotation axis; and
first mould tool parts assembled at least on two side surfaces which lie opposite one another.

17. An injection moulding tool according to claim 16 , wherein the tool carrier is configured to be translatorily and rotationally displaceable essentially simultaneously.

18. An injection moulding tool according to claim 15 , comprising:
at least one valve block for a feed, discharge and distribution of a hydraulic medium;
a cooling fluid and compressed air arranged to be last least one of within or on an upper side of the tool carrier which lies opposite the assembly plate.

19. An injection moulding tool with an assembly appliance for an injection moulding tool according to claim 1 , in combination with an injection moulding machine which comprises:
a translatorily displaceable mould clamping plate, wherein the assembly plate is configured for a translatory displacement which is essentially parallel to a translatory displacement direction of the mould clamping plate.

20. An injection moulding tool and machine according to claim 19 , wherein the translatorily displaceable mould clamping plate is configured to be displaced from a closed position into an open position, and vice versa, by a predefined first distance, and wherein the assembly plate is configured to be displaced from a closed position into an open position, and vice versa, by a second distance, wherein the first distance is essentially twice as large as the second distance.

21. An injection moulding tool and machine according to claim 20 , wherein the assembly plate is configured for a rotatory movement, such that the translatory displacement and the rotatory movement of the assembly plate will be effected essentially simultaneously.

22. An injection moulding machine in combination with an injection moulding tool according to claim 14 , wherein the injection moulding machine comprises:
a mould clamping plate which is translatorily displaceable along guide rail; and
a stationary mould clamping plate, wherein the injection moulding tool lies on the guide rails and is releasably connected to the stationary mould clamping plate.
