A lens mold carrier (1; 2) comprises: a frame (10; 20) extending in a plane (x,y; u,v) and comprising a plurality of individual compartments (100; 200); at least one mold unit (11; 21) arranged in one of the individual compartments (100; 200) in a manner secured against falling out, the at least one mold unit (11; 21) including an adapter piece (110; 210) and a lens mold (112; 212) fixedly connected to the adapter piece (110; 210). The adapter piece (110; 210) is floatingly arranged within the compartment (100; 200) to allow for limited movement of the adapter piece (110; 210) within the compartment (100; 200) at least in a translation plane parallel to or coincident with the plane (x,y; u,v) in which the frame (10; 20) extends.

A seal member formed in a line shape having ends is inserted in a seal groove formed on at least one of adjacent side surfaces of segments. A lip portion is provided on a seal upper portion of the member so at least a tip end thereof projects to an outside of the seal groove when the member is inserted in the groove. The seal member is hollow or includes a concave portion on at least a seal bottom portion thereof. When assembling the segments as a single structure, the adjacent side surfaces of the segments are coupled to each other, and the seal member is crushed in a cross sectional direction by the side surface of the other segment to seal between the segments. With this, complication of manufacturing steps can be suppressed or avoided while realizing a satisfactory sealed state between the adjacent segments of a mold.

The present invention relates to a wind turbine blade mould comprising a first mould part and a second mould part, where said first mould surface is configured for moulding a pressure side shell of a wind turbine blade, where said second mould surface is configured for moulding a suction side shell of a wind turbine blade, and where the wind turbine blade mould and thus also a wind turbine blade moulded in said mould comprise a first end, a second end, a pressure side shell, a suction side shell, and further comprise a leading edge area and a trailing edge area. The present invention also relates to a wind turbine blade and a manufacturing method for producing a wind turbine blade using a wind turbine mould as mentioned above.

Provided is a mold adapted for producing at least a part of a wind turbine blade, including a support and shell fixed to the support for accommodating blade building elements to be embedded in a resin matrix, wherein the shell includes at least one main body shell element and several diverse tip shell elements, which are exchangeably fixable to the support.

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.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

A molding element having a molding surface forming a contact face and a groove forming rib portion forming the groove comprising two opposed rib side faces and a rib top face connecting two rib side faces. The groove forming rib portion provides at least one space opening to at least one of the rib side faces and/or to the rib top face. An insert is received in the space. The insert comprises a cavity for forming a closing device in the groove. The cavity has two opposed cavity faces and opens to at least two faces of the insert corresponding to the faces of the groove forming rib portion. The insert comprises at least one cutting means extending and/or projecting in a direction the groove forming rib portion extends for cutting a material filled in the cavity during demolding.

A mold unit (22) for molding ophthalmic lenses comprises: an adapter piece (220) comprising an opening (2200) extending around a longitudinal axis (2201); a sleeve (221) fixedly connected to the adapter piece (220) and extending through the opening (2200) of the adapter piece (220); a lens mold (222) rigidly mounted to the sleeve (221); an adjustment ring (224) firmly attached to the sleeve (221) to circumferentially surround a portion of the sleeve (221).

The adjustment ring (224) comprises a flat circular outer engagement surface (2244), and the adapter piece (220) comprises at least one clamping block (2211) having a flat inner clamping surface (2214). The flat inner clamping surface (2214) frictionally clamps the flat circular outer engagement surface (2244) to prevent inadvertent rotation of the sleeve (221) relative to the adapter piece (220) but to allow rotation of the sleeve (221) relative to the adapter piece (220) upon the application of a torque higher than a predetermined threshold torque.

A manufacturing tool for forming composite structures includes at least one interchangeable mold template having a plurality of incorporated part shapes, and a backbone that connects to and supports the at least one interchangeable mold template during a process of laying up prepreg composite material to form a plurality of three-dimensional structures corresponding to the plurality of incorporated part shapes. A method for simultaneous manufacture of a plurality of composite structures includes providing an interchangeable mold template having a plurality of three-dimensional part shapes, fastening the interchangeable mold template to a backbone structure, laying up prepreg material over the interchangeable mold template to form a material layer, repeating laying up prepreg material to form a plurality of material layers each having a predetermined fiber orientation, and curing the plurality of material layers on the interchangeable mold template to form a plurality of structures corresponding to the three-dimensional part shapes.
