Moulding device and production process
A production process includes providing an envelope and a mould, introducing the material to be moulded in the mould, placing the mould in the envelope, creating a low pressure in the envelope, and deforming the mould.
1. A moulding device comprising:
an envelope;
a mould, the mould being in the envelope;
a vacuum port to create a low pressure in the envelope; and
a deforming member to deform the envelope and the mould.
2. The device according to claim 1 , further comprising a film in the envelope.
3. The device according to claim 1 , further comprising two films in the envelope, one film being above and one film being under the mould.
4. The device according to claim 1 , further comprising a film in the mould.
5. The device according to claim 1 , wherein the deforming member is below the mould.
6. The device according to claim 1 , wherein the deforming member acts on the envelope.
7. The device according to claim 1 , wherein the deforming member comprises a jack.
8. The device according to claim 1 , further comprising a table, the envelope being on the table and the deforming member extending through the table.
9. The device according to claim 1 , further comprising ball joints between the deforming member and the envelope.
10. The device according to claim 1 , the deforming member being a template.
11. The device according to claim 1 , wherein the mould is deformed by the deforming member against gravity.
12. The device according to claim 1 , wherein the envelope is made of a supple material.
13. A production process comprising:
providing an envelope and a mould;
introducing a material to be moulded in the mould;
disposing the mould in the envelope;
creating a low pressure in the envelope; and
deforming the envelope and the mould.
14. The process according to claim 13 , wherein one or more films are disposed in the envelope, between the envelope and the mould.
15. The process according to claim 13 , wherein after introduction of the material in the mould, a film is placed between the material to be moulded and the mould.
16. The process according to claim 13 , comprising the supply of a deforming member selected from the group consisting of a jack and a template.
17. The process according to claim 13 , the process being repeated so as to obtain several moulded parts, the process then comprising assembling the moulded parts.
18. The process according to claim 13 , the process being implemented by a moulding device comprising:
the envelope;
the mould, the mould being in the envelope;
a vacuum port to create a low pressure in the envelope; and
a deforming member for the mould.
19. The process according to claim 13 , wherein envelope is made of a supple material.
20. The device according to claim 1 , wherein the deforming member is configured to act on an outer surface of the envelope to deform the envelope and the mould.
