Embodiment Construction
[0035] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.
[0036] The propeller casting molding method of the present invention, the propeller casting gating system that adopts, as figure 1 As shown, including the propeller sand core 2, the propeller sand core 4 vertically passes through the center of the propeller sand core 2, and forms a cavity with the propeller sand core 2 for forming the propeller in the propeller sand core 2, and the upper end of the propeller sand core 2 is connected to the riser 3. The lower end is connected to the tile gate sand core 1 for drainage. In the present invention, the propeller sand core 2 is assembled from a plurality of independent blade sand cores.
[0037] When making the blade sand core, install the paddle steel mold on the shell molding machine, align the sand blasting port of the shell molding machine, contr...
