Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade molds, in particular to a vacuum casting mold. Background Art

[0002] In the manufacture of large wind turbine blades, the blade root is a key component. It is related to the connection between the blade and the hub and must have sufficient strength and rigidity. The blade root is often prepared using a vacuum infusion process (VARTM), which uses vacuum pressure to drive the flow of the curing agent to impregnate the reinforcing material to form a prepreg, and the prepreg is heated and cured to form. In order to meet the requirements of material properties and Tg value, the prepreg is pre-cured before being heated and cured, that is, the prepreg is preliminarily cured at a certain temperature. Different materials have different process requirements for pre-curing treatment. For example, the prepreg can be pre-cured and heated using an oven or hydrothermal method. In order to meet different pre-curing conditions, the mold is required to meet both oven heating and water heating methods to achieve the production of different raw material products, while reducing mold investment and oven procurement costs and floor space.
