[0036] Specific working principle: before the recognition system works, the optical displacement sensor 11 is adjusted to a suitable position through the adjustment end 123. When the recognition system works, the mold 3 is placed on the rotating table 23.

When the optical displacement sensor 11 recognizes the recognition hole 31, the optical displacement sensor 11 transmits a signal to the controller. The controller controls the stepper motor 21 to stop rotating, and controls the stepper motor 21 to rotate according to the set program to rotate the mold 13 to a specific angle.
