The outer surface fits with the inner wall of the corresponding groove 22. The two moving blocks 26 located on the outer surface of the bidirectional screw 23 are respectively threadedly sleeved on the different thread directions of the outer surface of the bidirectional screw 23. A connecting rod 27 is fixed between the two corresponding moving blocks 26, and a movable groove 210 for cooperating with the connecting rod 27 is opened between the two grooves 22.

Since the two moving blocks 26 located on the outer surface of the bidirectional screw rod 23 are respectively threadedly sleeved on the different thread directions of the outer surface of the bidirectional screw rod 23, when the bidirectional screw rod 23 rotates, the two moving blocks 26 will move towards or away from each other on the screw rod.

The moving blocks 26 corresponding to the two positions are connected by the connecting rod 27 in the movable groove 210, so that their movements are more synchronized. As the moving block 26 moves, the clamping plate 28 at its upper end also moves. The movement of the clamping plates 28 on both sides in a mirror-image distribution moves closer to or farther away from each other, thereby achieving the clamping or loosening operation of the mold frame.

The reinforcement blocks 45 on both sides of the lower end of the movable plate 2 are slidably connected with the guide rails 44. The guide rails 44 provide additional support and guidance for the movement of the movable plate 2, and work together with the slide rails 4 and the electric sliders 41 to ensure the stability and straightness of the movable plate 2 during movement.

Since the two moving blocks 26 located on the outer surface of the bidirectional screw rod 23 are respectively threadedly sleeved on the outer surface of the bidirectional screw rod 23 at different thread directions, when the bidirectional screw rod 23 rotates, the two moving blocks 26 will move towards or away from each other on the screw rod. At the same time, the moving block 26 is also sleeved on the driven rod 24. The driven rod 24 plays a role in stabilizing the movement direction of the moving block 26, ensuring that the moving block 26 moves along a straight line.

[0023] The electric slider 41 can slide on the slide rail 4 after receiving the control signal. The upper ends of the four electric sliders 41 are fixedly connected to the movable plate 2. When the electric slider 41 moves, it can drive the movable plate 2 to slide on the bottom plate 1 as a whole. The limit blocks 43 at both ends of the slide rail 4 can limit the movement range of the electric slider 41 to prevent it from sliding out of the slide rail 4. The reinforcement blocks 45 on both sides of the lower end of the movable plate 2 are slidably connected to the guide rail 44. The guide rail 44 provides additional support and guidance for the movement of the movable plate 2, and works together with the slide rail 4 and the electric slider 41 to ensure the stability and straightness of the movable plate 2 during movement.

[0024] The clamping plate 28 is easy to install and disassemble on the moving block 26.
