Abstract
Provided herein is a wind turbine blade mold system having built in precision pins to locate structural components (e.g. spar caps) during layup of composite segments. A plurality of pins can be inserted into apertures within the mold, with discs attached to the pins to maintain fixed relative distance to spar caps positioned relative to the pins to ensure precise positioning, thereby preventing/inhibiting movement of the spar cap relative to the mold. The pins can include a first extension that pierce through the layers of composite layups, and protrude above the B-surface of the blade skin. Additionally, the pins can include a marker tip releasably attached to the pin top to provide visual identification of the pin and underlying structural components. The pins can remain embedded within the final molded part.
