[0002] Casting of blades is a commonly used manufacturing method, which is suitable for materials such as metal blades and plastic blades. For plastic blades, the commonly used casting method is plastic injection molding, which is to inject molten plastic material into the mold and take out the molded blade after cooling and solidification:

[0003] The existing fan blade molds are of customized type. The installation and replacement of the molds are often driven by multiple hydraulic cylinders to move and dock, and then cast and mold. After natural drying, the upper and lower molds are separated to take out the molded products.

[0004] This type of method directly uses a hydraulic cylinder to drive the moving mold. When installing the moving mold, it is directly installed on the telescopic end. The installation method is relatively complicated and requires natural heat dissipation to cool the casting liquid and form it. The forming speed is slow. For this reason, we propose a fan blade casting mold. Utility Model Content
