And the auxiliary groove 212 is rotatably connected to the guiding ring 223. The driving motor 221 can drive the rotating plate 222 to rotate, so that during demolding, complete demolding around the mold can be achieved. The guiding ring 223 in the auxiliary groove 212 makes the rotating plate 222 more stable when rotating. The rotating plate 222 can fix the connecting block 3.

[0029] Further, the clamping member 23 includes a right-angle plate 231, a hydraulic push rod 232 and a clamping block 233.

[0030] Embodiment 2

[0031] Please refer to Figure 1 、 Figure 2 and Figure 5 As shown, compared with Embodiment 1, as another implementation manner of the present utility model, a connecting block 3 is fixedly installed at the center of the surface of the rotating plate 222. A through groove 31 is opened on one side of the connecting block 3. Sliding grooves 32 are opened on both sides at the top of the connecting block 3. The connecting block 3 provides connection. The opening of the through groove 31 enables the storage of the rack 41 and the gear 42.

[0034] Working principle: First, move an injection mold driving demolding mechanism to the working position. In the first step, when demolding in other directions is required, control the drive motor 221 to start working. At this time, the drive motor 221 drives the rotating plate 222 to start rotating. At this time, the guiding ring 223 rotates inside the auxiliary groove 212. The drive motor 221 can drive the rotating plate 222 to rotate, so that during demolding, complete demolding around the mold can be achieved. The guiding ring 223 in the auxiliary groove 212 makes the rotating plate 222 more stable during rotation, and the auxiliary groove 212 improves the path. In the second step, after demolding is completed, control the hydraulic push rod 232 to drive the clamping block 233 to retract and leave the mold. The hydraulic push rod 232 can change the position of the clamping block 233 and drive the clamping block 233 away from the working area. The clamping block 233 can clamp the mold. In the third step, when the mold needs to be pushed away from the working area, control the stepping motor 43 to start working. The stepping motor 43 drives the gear 42 to engage and rotate on one side of the rack 41. The convex block 51 slides inside the sliding groove 32. At this time, the sliding plate 5 moves along with the gear 42 and takes the mold away from the working area. The stepping motor 43 can accurately control the rotation of the gear 42. The gear 42 engages and rotates with the rack 41, having high stability. The rack 41 provides a moving path for the gear 42. The sliding plate 5 can support the mold, and the convex block 51 assists the movement of the gear 42. The setting of the sliding groove 32 enables the convex block 51 to move along the path provided by the sliding groove 32. In this way, the use process of an injection mold driving demolding mechanism is completed.
