Abstract

A tool is disclosed for the production of foamed insulation boards with two side faces lying opposite one another and all-round end faces such as facade insulation boards for insulating buildings. The tool has two mold halves, each having a mold frame and a mold base. The two mold halves together bound a mold cavity, which corresponds roughly to an insulation board to be produced, with the mold frames defining or bounding the end faces of the insulation board to be produced and the mold base defining or bounding the side faces. A setting device sets the position of the two mold halves in a plane parallel to the mold bases. The setting device is designed for stepless setting of the position of the two mold halves relative to one another.

Claims

1. A tool for production of foamed insulation boards, wherein the insulation boards have two side faces lying opposite one another and all-round end faces, the tool comprising:

two mold halves, each having a mold frame and a mold base, so that the two mold halves together bound a mold cavity, which corresponds roughly to an insulation board to be produced, wherein the mold frames define the end faces of an insulation board to be produced, and the mold bases define the side faces of an insulation board to be produced,

a setting device for setting the position of the two mold halves in a plane parallel to the mold bases.

2. The tool according to claim 1, wherein the setting device is designed for stepless setting of the position of the two mold halves relative to one another.

3. The tool according to claim 1, wherein the mold frames have the shape of a rectangle and the setting device is designed for setting the position of the two mold halves in a direction inclined through 45°

to the edge of the rectangle.

4. The tool according to claim 1, wherein each of the mold halves has a press frame which may be connected to a press, and arranged on one of the two press frames is an adjusting frame to which one of the mold frames and one of the mold bases are fixed, and the adjusting frame is mounted movably on the press frame, and an actuator is provided for stepless movement of the adjusting frame relative to the press frame.

5. The tool according to claim 4, wherein the actuator has an electrical, hydraulic or pneumatic drive unit.

6. The tool according to claim 4, wherein the press frame comprises claws for fixing the adjusting frame, the claws being operated hydraulically, pneumatically or electrically.

7. The tool according to claim 4, further comprising a slide bearing between the adjusting frame and the corresponding press frame.

8. The tool according to claim 7, wherein the slide bearing supports two contact faces of the adjusting frame and the press frame, which are arranged roughly parallel to the mold bases and have a slide plate and/or a ball bearing.

9. The tool according to claim 4, wherein the press frame comprises at least one load hearing which, with vertical arrangement, fits closely on a lower end face of the adjusting frame, wherein the adjusting frame has adjacent to the load bearing a trough-shaped recess open at the bottom, so that the load bearing in a zero position abuts an apex of the recess.

10. The tool according to claim 1, further comprising a depth setting device, by which the mold base of one of the mold halves are moved relative to the corresponding mold frame in a direction roughly perpendicular to the plane of the mold base.

11. The tool according to claim 1, wherein the mold bases have one or more steam feed inlets.

12. The tool according to claim 1, wherein at least one of the mold frames and/or at least one of the mold bases has a filler connection for the supply of foam particles.

13. The tool according to claim 1, further comprising at least one locating pin, which, by means of a linear actuator, is extended into the mold cavity and retracted from the mold cavity.

14. The tool according to claim 1, wherein the foamed insulation boards are facade insulation boards for the insulation of buildings.

15. An apparatus for production of foamed insulation boards, the apparatus comprising:

a tool comprising two mold halves and a setting device, each of the two mold halves having a mold frame and a mold base, so that the two mold halves together bound a mold cavity, which corresponds roughly to an insulation board to be produced, wherein the mold frames define the end faces of an insulation board to be produced, and the mold bases define the side faces of an insulation board to be produced, and wherein the setting device sets the position of the two mold halves in a plane parallel to the mold bases; and

a press, by which the two mold halves are pressed together.

16. The apparatus according to claim 15, further comprising a heating device for heating the mold cavity, wherein the heating device has a steam generator to produce steam and/or a generator for the generation of electromagnetic waves.

17. The apparatus according to claim 15, wherein the foamed insulation boards are facade insulation boards for the insulation of buildings.

18. A method for production of foamed insulation boards, wherein the insulation boards have two side faces lying opposite one another and all-round end faces, the method comprising:

providing a tool comprising two mold halves, each having a mold frame and a mold base, so that the two mold halves together bound a mold cavity, which corresponds roughly to an insulation board to be produced,

using the mold frames to define the end faces of an insulation board to be produced;

using the mold bases to define the side faces of an insulation board to be produced; and

setting the position of the two mold halves in a plane parallel to the mold bases by setting of the position of the two mold halves relative to one another.
