[0030] Specifically, the electric push rod 6 is started, and the output end of the electric push rod 6 drives the linkage plate 15 to move, and then drives the fixed plate 12 to move, so as to adjust the height of the lower mold 7, and then rotate the lower mold 7 to make the rotor workpiece 14 and the lower mold base 2 face each other, and the rotor workpiece 14 is discharged from the fixed groove 17.

[0031] Example 2: Please refer to Figure 1-4 In this embodiment, on the basis of the first embodiment, a support assembly is provided on the lower die base 2, and the support assembly includes two positioning rods 10, and the two positioning rods 10 are fixedly connected to the top surface of the lower die base 2.
