Abstract

A tooling device for making a plastic film component. The tooling device includes a molding tool having a molding part, a receptacle, an opening and closing device, and at least one covering device having a covering surface and guide arrangement. The molding part and the receptacle are movable relative to each other between a closed and an open position. Relative movement between the molding part and the receptacle to the closed position is transmitted to the covering device to move it from an exposed position, in which the covering surface is spaced from an inner surface of the molding part, to a covered position, in which the covering surface covers a covered section of molding part's inner surface.

First claim

The invention claimed is:

1. Tooling device for making a plastic film component, the tooling device comprising:
a molding tool, comprising a molding part with a molding part inner surface, a receptacle and an opening and closing device,
at least one covering device with a covering surface,
an abutment device,
a guide arrangement with a first and a second guide device, wherein the first guide device couples the covering device to one of the components (a) the receptacle or (b) the molding part as a first molding tool component for movement purposes, wherein the second guide device couples the covering device and the abutment device for movement purposes, and
an activation device that couples the abutment device and the other of the components (a) and (b) as a second molding tool component for movement purposes,
wherein, when the first and second molding tool components move relative to each other to move the molding tool from an open to a closed position, the abutment device with the second molding tool component are brought to bear on each other in a molding tool bearing position, whereby the abutment device moves in dependence of the movement of the second molding tool component and, by guidance of the first and second guide device, the covering device is moved from an exposed position, in which the covering surface thereof is at a distance from the molding part inner surface of the second molding tool component to a covering position in which the covering surface covers a section of the molding part inner surface.

2. Tooling device according to claim 1 , wherein the activation device couples the abutment device to the receptacle, wherein, when the molding tool is in the closed position, the abutment device is in the covered position on the molding part inner surface, wherein the abutment device is fixed on a first guide component, which is coupled for movement purposes with a second guide component fixed to the covering device.

3. Tooling device according to claim 1 , wherein the first guide device comprises a first guide component extending flat in a lengthwise direction and the second guide device comprises a second guide component extending flat in a lengthwise direction, which bear on each other during a movement by molding part and receptacle to the closed position thereof, and are guided alongside each other in the respective lengthwise directions thereof, thereby deflecting the movement of molding part and receptacle relative to each other to the closed position into a movement of the covering device into the covered position.

4. Tooling device according to claim 1 , wherein the second guide device is constructed according to one of the two following alternatives:
the second guide device includes: a guide track, which is fixed on the covering device and a second coupling element guided movably thereon, which is fixed on the abutment device,
the second guide device includes: a guide track, which is fixed on the abutment device, and a second coupling element which is guided movably thereon, which is fixed on the covering device.

5. Tooling device according to claim 4 , wherein the connecting device is connected to a third coupling element and wherein the third coupling element is coupled to a third guide track, which is fastened to the receptacle or a support section thereof.

6. Tooling device according to claim 1 , wherein second guide device includes:
a telescoping assembly, which is mounted rotatably on the first molding tool component,
a first telescoping coupling, with which the telescoping assembly is coupled for movement purposes with the abutment device,
a second telescoping coupling, with which the telescoping assembly is coupled for movement purposes with the covering device.

7. Tooling device according to claim 1 , wherein the tooling device comprises a biasing device, which biases the abutment device into a position, viewed from the receptacle in a direction towards the molding part.

8. Tooling device according to claim 1 , wherein the covering device comprises a base body and a covering body movable therein.

9. Tooling device according to claim 1 , wherein the molding tool comprises a biasing device, with which the covering device is biased against the base body into the exposed position.

10. Tooling device for making a plastic film component, the tooling device comprising:
a molding tool, comprising a molding part with a molding part inner surface, a receptacle, and an opening and closing device, with which the molding part and the receptacle are movable relative to each other between a closed and an open position,
at least one covering device with a covering surface, and
a guide arrangement having a first guide device, via which the covering device is coupled for movement purposes to one of the components (a) the receptacle or (b) the molding part, and with a second guide device which couples the covering device to the other of the components (a) and (b), wherein due to the guide arrangement the covering device is movable between a covered position, in which the covering surface covers a section to be covered of the molding part inner surface, and an exposed position, in which the covering surface is at a distance from the molding part inner surface, wherein the movement between the covered position and the exposed position is mechanically coupled to the movement of the molding part relative to the receptacle relative to each other into the closed position.

11. Tooling device according to claim 10 , wherein the first guide device is designed as a first guide component extending flat in the lengthwise direction and arranged on the covering device and the second guide device is designed as a second guide component extending flat in a lengthwise direction and arranged on the other of the components (a) and (b), wherein with molding part and receptacle in an intermediate bearing position the first guide component and the second guide component are brought to bear on each other and at the approach of molding part and receptacle move towards each other in their lengthwise directions, thereby bringing the covering device from the exposed position into the covered position.

12. Tooling device according to claim 10 , wherein the second guide device is constructed according to one of the following alternatives:
the second guide device includes: a second guide track, which is fixed to the covering device as a second guide component, and a second coupling element guided movably thereon, which is fixed to molding part,
the second guide device includes: a second guide track, which is fixed to the molding part as a second guide component, and a second coupling element guided movably thereon, which is fixed to the covering device.

13. Tooling device according to claim 10 , wherein the second guide device includes: a first guide component and a second guide component, which bear on each other when molding part and receptacle move to their closed position, and are guided along their respective lengthwise directions, and thereby deflect the movement of the molding part and the receptacle relative to each other to the closed position into a movement of the covering device into the covered position.

14. Tooling device according to claim 13 , wherein the first guide component comprises a first outer guide surface and the second guide component comprises a second guide surface, which is conformed on a bracket arranged on the molding part and positioned in an interior space, and the first outer guide surface and the second guide surface slide along each other between the intermediate bearing position and the covered position.
