[0024] Embodiment 1

[0025] like Figure 1 It is shown that the servo motor 1 is used to drive the movable template 3 to directly flip, and it can rotate 360° without dead angle. The angle and speed of the movable template 3 can be adjusted arbitrarily, which enhances the processability, makes the flipping of the movable template 3 without dead point, and is convenient for adjusting the parallelism of the template;

[0026] Embodiment 2

[0027] like Figure 2-4 As shown in the figure, when the servo motor 1 drives the moving plate 3 to rotate 90° from the horizontal state to the vertical state, the clamping rod 15 slides out from the frame 4 in the horizontal state, and the clamping rod 15 moves upward for a certain distance. The upper end of the clamping rod 15 pushes the cross plate compression spring 13 and drives the guide rod 11 to move upward. The lower end of the guide rod 11 drives the piston 9 to move upward for a certain distance to open the sealing groove. At this time, the lubricating oil in the oil storage tank 16 flows along the sealing groove through the liquid outlet pipe 10 to the bearing 5, lubricating the gap between the inner ring and the outer ring of the bearing 5, and also lubricating the rotating shaft of the inner ring, thereby reducing the loss of the bearing and the rotating shaft and extending the service life of both; until After the movable template 3 rotates from a horizontal state to a vertical state, the clamping rod 15 just moves to the next frame 4. At this time, the clamping rod 15 is pushed into the frame 4 again under the action of the elastic force of the spring 13. Since the lower ends of the frame 4 and the clamping rod 15 are both arranged in a trapezoidal shape, the frame 4 can only rotate in one direction and cannot rotate. When the clamping rod 15 is clamped into the next frame 4, the servo motor 1 stops rotating. At this time, the position and angle of the limit disk 12 are relatively stable, so that the rotating shaft no longer rotates, so that the movable template 3 always remains vertical, thereby improving the stability of the movable template 3, and thus improving the accuracy of the processed products between the movable template 3 and the fixed mold.
