Patent ID: 8770966

Claim:
A mould assembly for manufacturing a wind turbine blade, comprising: two mould parts, a first mould part and a second mould part, for manufacturing a elongated closed profile member, including the wind turbine blade of fibre-reinforced polymer, said mould assembly further comprising a hinge mechanism, which is detachably connected to the two mould parts, the hinge mechanism further comprising at least a first hinge axis and a second hinge axis extending parallel to each other with a first mutual distance and parallel to the two mould parts in the longitudinal direction of the mould so that the mould parts are pivotable with respect to each other between a first, open position, where the two mould parts are located adjacent each other with a second mutual distance and with the openings of the two mould parts facing upwards, and a second position, where the first mould part is rotated around the first hinge axis by a first drive means so that the opening of said first mould part faces to the side and towards the second mould part, and a third position, where the first mould part is further rotated from the second position around the second hinge axis by a second drive means so that the opening of said first mould part faces downward towards the opening of the second mould part and is aligned therewith, thereby defining a mould cavity configured for the elongated closed profile member, wherein: the first mould part between the first and the second position describes a first circular arc, the first mould part between the second and the third position describes a second circular arc, the first mould part is rotated 180 degrees about the first and second hinge axes with respect to the second mould part, the first hinge axis is located along a side of the first mould part and the second hinge axis is located along a side of the second mould part, a workspace is created between the two mould parts in the first, open position of the mould assembly, and the first mould part and the second mould part in the first, open position rest on a floor or another surface, wherein the first hinge axis and the second hinge axis are connected by means of at least one connecting arm, wherein the at least one connecting arm includes a main plane that faces upward in the first and second positions, and faces towards the second mould part in the third position.
