Abstract

A tool for producing a fiber composite component includes at least two tool portions which have partial cavities and which are moved together in a production position in such a manner that they form a cavity, in which cavity the fiber composite component is produced. Associated with at least a first tool portion there is a retention element which retains the fiber composite component produced in the first tool portion when the tool portions are moved apart after the production of the fiber composite component.

First claim

What is claimed is:

1. A tool for producing a fiber composite component, the tool comprising:
at least two tool portions, each tool portion defining half of a first recess, the at least two tool portions being moved together in a production position in such a manner that they form a cavity, in which cavity the fiber composite component is produced; and
a retention element that is associated with at least a first tool portion, the retention element being configured to retain the fiber composite component produced in the first tool portion when the tool portions are moved apart after the production of the fiber composite component, wherein
the first recess encapsulates at least the retention element and a pivotable retention portion, and
the retention element is pivotable between: i) an initial position when the tool portions are moved together, and ii) a retention position, that is different from the initial position, just before the tool portions are moved apart,
along a first axis of the tool the first recess and the cavity are equal in size, and along a second axis of the tool the cavity is larger than the first recess,
the retention element is a pneumatically, hydraulically or electrically actuatable tensioner,
the tool portions each have surfaces with which the fiber composite component to be produced is in contact,
the surfaces are plasma-nitrided, mirror-polished or chromium-plated, and
the tool has a removal element which removes the fiber composite component produced from the tool.

2. The tool as claimed in claim 1 , wherein the retention portion has a first end that is connected to a drive and a second end that defines a mounting head.

3. The tool as claimed in claim 1 , wherein the removal element comprises at least one vacuum suction device via which the fiber composite component produced is removable.

4. The tool as claimed in claim 1 , wherein the removal element is a robot with a movable arm.

5. The tool as claimed in claim 4 , wherein at least one air ejector is provided in at least one of the tool portions.

6. The tool as claimed in claim 5 , wherein the retention element is provided in both tool portions.

7. The tool as claimed in claim 3 , wherein the removal element is a robot with a movable arm.
