The wind wheel mold 3 is provided with a mold body 31, the mold body 31 is a columnar ring, the mold body 31 is made of metal materials, and the mold body has the characteristics of high hardness and the like, and can be made of aluminum metal. The die body 31 uses its centre of a circle as the central N equally divides N modules 311, and the module 311 is the arc setting, and the shape and the radian of N modules 311 are the same, and the center department of the die body 31 is used as the centre of a circle to N modules 311, then when N modules 311 are circular arrangement connection, can constitute the die body 31. After N modules are manufactured in an independent manufacturing mode, the wind wheel die is assembled, so that the manufactured wind wheel die is higher in precision, and the manufacturing difficulty is reduced.
The structure of each module 311 is the same, so that the connection between the adjacent modules 311 can be achieved by the simplest and convenient fastening manner, that is, the side surfaces of the adjacent modules 311 are respectively provided with a clamping protrusion 312 or a clamping groove 313, so that the adjacent modules 311 are matched with each other through the clamping protrusion 312 and the clamping groove 313.
Because each module 311 is assembled in a circumferential arrangement, if the adjacent modules 311 are easily separated by a simple left-right buckling manner, the wind wheel mold is separated when rotating at a high speed, and therefore, the connection between the adjacent modules 311 adopts a plug-in type structure as follows:
a locking protrusion 312 is disposed on one side of the module 311, and a locking groove 313 is disposed on the other opposite side, wherein the locking groove 313 penetrates through the upper and lower bottom surfaces of the module 311.

Such that the cross section of the module 311 is approximately concave in shape as seen in cross section, this design allows the connection to be reinforced since both sides of the module 311 are intended to be connected to adjacent modules. When the wind wheel mold is assembled in an automatic assembling machine for use, the wind wheel mold runs at a high speed, the centrifugal force is decomposed by a plurality of modules under the action of the centrifugal force, and the force interaction among the modules is contradicted, so that the decomposition of the force is effectively carried out, and the wind wheel mold 3 is not easy to deform.
