The frame 1 is used as a carrier of the whole equipment, the frame 1 can be set as a cabinet, is provided with a frame door and a packaging plate, and belongs to the common structural form of the prior automatic equipment. The frame 1 is divided into an upper part and a lower part by taking a large panel as a distinction, the lower part is mainly used for assembling a circuit board and electric components of equipment, and the packaging board is used for shielding and protecting. The upper part of the frame 1 is semi-open, which is convenient for a user to observe the current processing condition.

The slide rail 11 and the slide block 21 are all arranged in a straight line, and the processing platform 2 is driven to move by a driving device, and the driving device can be a motor or an air cylinder.
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. During splicing, the clamping convex 312 of the first module A11 is connected with the clamping groove 313 of the second module B11, so that the assembly of the two modules is completed; the clamping groove 313 can be designed into a cylindrical groove, namely, the clamping groove 313 is a groove body with a small opening and a large cavity, and the opening of the groove body faces outwards; the clamping convex 312 is matched with the cylindrical groove, so that adjacent modules 311 cannot be buckled by transverse force, the clamping convex 312 must be moved downwards from the top of the clamping groove 313 (namely the end face of the module 311) to the corresponding clamping groove 313, and the adjacent modules 311 cannot be disassembled under the transverse acting force due to the design mode of the cylindrical groove.
After the modules 311 are assembled and connected in this order, a columnar circular ring-shaped mold body 31 is formed.
The outer wall of the wind wheel mould 3 is provided with an inserting slot 30, the inserting slot 30 is uniformly formed on the outer wall of the wind wheel mould 3, and the inserting slot 30 is used for inserting blades during processing.
The side walls of the insert slot 30 are arranged in an arc shape, and the two side walls are symmetrical.
The wind wheel die assembled in the mode is high in precision, and the module 311 is assembled in a clamping mode from top to bottom, so that the wind wheel die cannot be disassembled when the module 311 is subjected to centrifugal force during high-speed rotation of the wind wheel die, and normal use of the wind wheel die is effectively ensured.
More specifically, the module 311 is made of metal, and in order to enhance toughness, a concave portion 310 is formed on the inner wall of the module 311 at a middle position of a connection line between the clamping groove 313 and the clamping protrusion 312. 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.
