Abstract

Provided is a mold adapted for producing a wind turbine blade, including a first carrier and a shell for accommodating blade building elements to be embedded in a resin matrix for building a blade body part, which shell is placed on the first carrier, and a second carrier changeable in its length and elongating the first carrier adapted to accommodate a prefabricated blade tip to be connected to the blade body part when the blade body part is built.

First claim

The invention claimed is:

1. A mold adapted for producing a wind turbine blade, comprising: a first carrier and a shell for accommodating blade building elements to be embedded in a resin matrix for building a blade body part, which shell is placed on the first carrier, and a second carrier changeable in its length and elongating the first carrier adapted to accommodate a prefabricated blade tip to be connected to the blade body part when the blade body part is built, herein the second carrier comprises a plurality of carrier elements telescopically linked in a row and movable with at least one actuator, wherein each carrier element of the plurality of carrier elements comprises at least one frame element, wherein the at least one frame element of a respective carrier element engages with the at least one frame element of an adjacent carrier element such that the plurality of carrier elements are telescopically linked, wherein ach carrier element of the plurality of carrier elements comprises at least one saddle-like support element or carrying the prefabricated blade tip, and wherein the at least one saddle-like support element is connected to a lifter for changing a position of the at least one saddle-like support element.

2. The mold according to claim 1 , wherein the lifter comprises at least one telescope cylinder.

3. The mold according to claim 2 , wherein each support element is connected with both ends to a separate cylinder, with each cylinder being separately controllable.

4. The mold according to claim 1 , wherein at least one carrier element comprises a standardised connection interface for connecting it to a connection interface of the first carrier.

5. The mold according to claim 4 , wherein connections realised by the respective connection interfaces are flange connections or are plug-in connections using snap-on, latching, or tube-like connection elements.

6. The mold according to claim 1 , wherein each carrier element comprises a standardised connection interface for connecting it to an adjacent carrier element or to a connection interface of the first carrier.

7. The mold according to claim 6 , wherein connections realised by the respective connection interfaces are flange connections or are plug-in connections using snap-on, latching, or tube-like connection elements.

8. The mold according to claim 1 , wherein the carrier elements are arranged such that the carrier elements are moved sequentially when the second carrier is extended from a retracted to an extended position and vice versa, or that the carrier elements are all synchronously moved.

9. The mold according to claim 1 , wherein the actuator is a cylinder.

10. The mold according to claim 1 , wherein the first carrier comprises several first carrier elements arranged and connected in a row.
