Description

Technical Field

[0001] The present invention relates to a mold closing structure for a wind power blade mold. Background Art

[0002] A wind turbine is a power device that converts wind energy into mechanical work, the mechanical work drives the rotor to rotate, and finally outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a yaw device, a tower, a speed limit safety mechanism, and an energy storage device. In the production of wind turbine accessories such as wind turbine blades, injection molding and other technological processes need to be carried out using blade molds.
