Abstract

An arrangement for consolidating thermoplastic semi-finished products includes a heating station for heating a semi-finished product, and a tempering station for tempering, in particular cooling, the semi-finished product. At least one mold can be arranged in the heating station and in the tempering station, and comprises a cavity for receiving the semi-finished product, the cavity substantially corresponding to a form of the semi-finished product. A mold transport device can transport the at least one mold from the heating station into the tempering station, and from the tempering station into the heating station.

First claim

The invention claimed is:

1. An arrangement for consolidating thermoplastic semi-finished products, comprising:
a heating station for heating a semi-finished product;
a tempering station for tempering the semi-finished product;
a mold to be arranged in the heating station and in the tempering station, the mold comprising a cavity for receiving the semi-finished product, the cavity substantially corresponding to a form of the semi-finished product;
a mold transport device configured to transport the mold is from the heating station into the tempering station and from the tempering station into the heating station; and
lifting devices provided at the heating station and/or the tempering station, the lifting devices being configured to lift the mold to be lifted, the lifting devices including a hydraulic cylinder for lifting.

2. The arrangement according to claim 1 , wherein the mold is a first mold of at least two molds.

3. The arrangement according to claim 1 , wherein the mold comprises at least two mold parts, the cavity being formed when the at least two mold parts abut each other, and wherein the mold is openable by moving the mold parts away from each other.

4. The arrangement according to claim 1 , wherein the heating station and/or the tempering station each comprise platens movable relative to each other for opening and closing the heating station and/or the tempering station.

5. The arrangement according to claim 3 , wherein the tempering station comprises at least one coupling element configured to couple at least one of the at least two mold parts to at least one of the platens, whereby the mold is configured to be opened by opening the tempering station.

6. The arrangement according to claim 1 , wherein the mold transport device comprises a belt drive.

7. The arrangement according to claim 6 , further comprising at least one latching device for latching the mold to the belt drive, and for unlatching the mold from the belt drive.

8. The arrangement according to claim 7 , wherein the latching device comprises movable pins.

9. The arrangement according to claim 1 , wherein the lifting devices include at least two hydraulic cylinders for lifting.

10. The arrangement according to claim 1 , wherein the mold transport device comprises a rotary table.

11. The arrangement according to claim 1 , wherein the mold transport device comprises a handling robot.

12. The arrangement according to claim 1 , further comprising a demold station separate from the heating station and from the tempering station, the demold station being configured to remove the semi-finished product from the mold, the mold transport device being configured to transport the mold from the tempering station to the demold station.

13. The arrangement according to claim 1 , further comprising a receiving station configured to bring the semi-finished product to the mold, the mold transport device being configured to transport the mold from the receiving station to the heating station.

14. The arrangement according to claim 1 , further comprising:
a molding machine for processing the consolidated thermoplastic semi-finished products, and
a handling device for transporting the semi-finished product to the molding device.

15. The arrangement according to claim 1 , wherein the heating station comprises heating plates for heating the mold and/or wherein the tempering station comprises tempering plates for tempering the mold.

16. The arrangement according to claim 15 , further comprising a suction device and a seal for substantially hermetically sealing a room between (i) the mold and (ii) the heating plates and/or the tempering plates, wherein the seal is flexible such that the mold contacts the heating plates and/or the tempering plates when the room is put under low pressure by the suction device.

17. The arrangement according to claim 4 , wherein the tempering station comprises a coupling element with which at least one of the at least two mold parts can to at least one of the platens, whereby the mold can be opened by opening the tempering station.

18. The arrangement according to claim 1 , wherein the tempering station is configured to cool the semi-finished product.

19. The arrangement according to claim 8 , wherein the latching device comprises pneumatically movable pins.
