[0012] The present invention will be further described below in conjunction with specific drawings.
[0013] The method for preventing product stripping during the mold closing process of the megawatt-level blade comprises the following steps:
[0014] (1) if figure 1 , figure 2 As shown, the blade product 1 is placed in the mold 2, the edge of the mold 2 is the flange side 3, one side of the flange side 3 is connected with the blade product 1, and a seal is set between the flange side 3 and the blade product 1 Bar 4, a sealing strip 4 is also provided between the other side of the flange side 3 and the mold 2, thereby forming a sealed environment between the mold 2 and the blade product 1, ensuring that the mold 2 and the blade product 1 themselves do not leak;
[0015] (2) Arrange the air extraction pipe 5 on the flange side 3, and the sealing strip 4 is also used to seal the air extraction pipe 5 and the flange side 3; vacuumize through the air extraction pipe 5 to make ...
