Abstract

The invention relates to a centrifugal cast-aluminum die of an electrical machine rotor, which is characterized by comprising an upper die part, a lower die part and a rotor core pressing part. The upper die core of the upper die part is connected on an upper die base through a socket head cap screw. The lower die core of the lower die part is connected on a lower die plate through a socket head cap screw. The top cap of the rotor core pressing part is fixed on a false shaft through an outer hexagonal bolt, a straight key is arranged in a false shaft groove, the lamination sheet of the rotor core is sheathed into the false shaft through the locating of the straight key, the top cap is fixed by an outer hexagonal bolt and compresses the lamination sheet of the rotor core, the rotor core is arranged in the locating holes of the upper die core and the lower die core. The die of the invention has simple, compact and rational structure. The upper die core and the lower die core of the die adopt the integrated structure, thereby reducing the working load of metalworking process, the assembling and inserting, greatly reducing the manufacturing cost of the die, shortening the manufacturing time of the die and ensuring the manufacturing accuracy of the die.

Description

technical field [0001] The invention relates to a centrifugal casting aluminum mold for a motor rotor, in particular to a mold for manufacturing a motor casting aluminum rotor, which belongs to the processing technology equipment of motor parts. Background technique [0002] In the prior art, the upper mold cavity and the lower mold cavity of the centrifugal cast aluminum mold used in the manufacture of cast aluminum rotors for electric motors are fastened to the upper and lower mold rings with multiple inserts and screws. The processing procedures are complicated and the manufacturing cost is high. The mold production cycle is long and the accuracy is not easy to guarantee, which not only wastes manpower and financial resources, but also greatly reduces work efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a motor rotor centrifugal casting aluminum mold that can improve work effic...
