A turning system for turning wind turbine blade shell part carriers between an open position and a closed position about a turning axis, comprising: a lower blade shell part carrier having a support surface for receiving and supporting a lower wind turbine blade part; an upper blade shell part carrier and having a support surface for receiving and supporting an upper wind turbine blade part; and at least one turning device each including: a lower hinge element, such as a beam, arranged under the support surface of the lower blade shell part carrier; and a turning hinge having a lower hinge part attached to the respective lower hinge element, an upper hinge part attached to the upper blade shell part carrier, and an actuator configured for turning the lower and upper hinge parts relative to each other about the turning axis.

A closing device for a mold group with two half-molds extends along a main axis and has a device body mountable to one of the two half-molds, and a closing group having a closing element rotatable about a rotation axis between a closing position, in which the two half-molds are lockable and an opening position, in which the two half-molds are releasable. A movement group housed in the device body and engaged with the closing group to rotationally move the closing element has a stem movable along the main axis and transmission members for transforming linear motion of the stem into rotatory motion of the closing element. A command group has a command plate engaged with one command end of the stem and a metal sealing bellows engaged with the command plate. A position of the metal sealing bellows corresponds to an axial position of the command plate and of the stem.
