A wind turbine blade mold system has been granted a patent (Publication Number: US11884027B2) with a set of claims outlining the components and method involved. The system includes a first mold surface with at least one aperture, studs, pins, discs, layup segments of fiber material, and pin extensions. The system is designed to facilitate the formation of wind turbine blades by engaging structural components such as spar caps. The method involves providing the mold surface, studs, pins, and discs, depositing fiber material, inserting the structural component, and attaching the discs to engage the component.

The system and method described in the patent claims aim to streamline the process of forming wind turbine blades by providing a structured approach to mold design and blade assembly. By incorporating elements such as pins, discs, and layup segments in a specific configuration, the system ensures efficient and accurate placement of components during the blade formation process. The method also includes steps for replacing pin extensions with different profiles to accommodate various stages of the assembly process, such as piercing layup segments and securing a vacuum bag. Overall, the patented system and method offer a comprehensive solution for manufacturing wind turbine blades with precision and reliability.
