[0025] The swing plate 604 is rotatably connected to the movable seat 5 via a connecting shaft, and the bottom end of the swing plate 604 is connected to one side of the top end of the movable box 7;

[0026] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, the rotating disk 603 rotates, and the guide rod 606 cooperates with the through hole 605 to realize the reciprocating swing of the swing plate 604, so that the grinding angle of the grinding head 11 changes, so that it can adapt to the mold cavity structure inside the tire mold body 8, so as to improve its grinding efficiency;

[0027] A guide groove 16 is provided on the outside of the turntable 603, and a guide plate 15 is installed on the top of the movable seat 5 below the turntable 603. The top of the guide plate 15 is a curved surface, and balls 14 are evenly installed on the top of the guide plate 15. The top of the ball 14 abuts against the top of the guide groove 16.
