Through the sliding action of the fixed rod 203 and the ejection action of the demolding ejector rod 204, the fan blade is ejected from the inside of the fan blade injection molding cavity for demolding when the first mold 3 moves left to separate from the second mold 4. This avoids the situation that the thin part of the fan blade is too close to the inside of the fan blade injection molding cavity and cannot be demolded in time, helps to improve the demolding efficiency, and cooperates with the demolding agent to help reduce the damage of the weak part of the fan blade.
