Four guide plates 14 are fixed to the top surface of the second mounting plate 2. Guide grooves 15 are provided on the outer sides of the guide plates 14. Slide blocks 16 are slidably connected to the inner sides of the guide grooves 15. Both ends of the slide blocks 16 are fixedly connected with connecting rods 17. The upper ends of the connecting rods 17 pass through the interior of the movable groove 4 and the interior of the through groove 7 in sequence and are fixedly connected to the bottom surface of the connecting plate 8. The four splints 6 are arranged in a rectangular shape, and the positions of the four splints 6 correspond to the positions of the four movable grooves 4. The four movable grooves 4 are arranged in a cross shape. The position of one of the two-way screw rods 12 is higher than the position of the other two-way screw rods 12. The two two-way screw rods 12 are arranged in a cross shape. The connecting block 13 is located inside the movable groove 4, and the guide groove 15 includes a horizontal section and an inclined section.

[0023] By turning the handle 5, the bidirectional screw rod 12 is driven to rotate, and the bidirectional screw rod 12 drives the two clamps 6 toward the middle through the two connecting blocks 13, so that the two clamps 6 clamp the mold. In this process, the connecting rod 17 is driven synchronously, and the connecting rod 17 drives the slider 16 to move along the guide groove 15. When the slider 16 moves from the horizontal section in the guide groove 15 to the inclined section, the slider 16 moves downward while moving toward the middle, and the slider 16 drives the connecting rod 17 to move downward along the through groove 7 on the clamp 6. The connecting rod 17 drives the connecting plate 8 to move downward, and the connecting plate 8 is driven by the spring 11 drives the top plate 10 to move downward and contact the top surface of the mold. As the splint 6 gradually approaches the mold, the connecting plate 8 continues to squeeze the spring 11. The pressure of the spring 11 pushing the top plate 10 on the mold continues to increase. When the splint 6 completely clamps the mold, the squeezing of the spring 11 by the connecting plate 8 reaches the maximum, so that the pressure of the top plate 10 on the mold reaches the maximum. Through the above process, the mold can be clamped from the horizontal and vertical planes at the same time, thereby solving the problem of poor stability due to the use of splints for clamping, because the force of the splints is on the same plane and there is a lack of vertical force.

[0024] Specific usage and function of this embodiment: The utility model drives the bidirectional screw rod 12 to rotate by rotating the handle 5, and the bidirectional screw rod 12 drives the two clamping plates 6 to move closer to the middle through the two connecting blocks 13, so that the two clamping plates 6 clamp the mold. In this process, the connecting rod 17 is driven synchronously, and the connecting rod 17 drives the slider 16 to move along the guide groove 15. When the slider 16 moves from the horizontal section in the guide groove 15 to the inclined section, the slider 16 moves downward while moving toward the middle, and the slider 16 drives the connecting rod 17 to move downward along the through groove 7 on the clamping plate 6. The connecting rod 17 drives the connecting plate 8 to move downward. The connecting plate 8 drives the top plate 10 to move downward through the spring 11 and contacts the top surface of the mold. As the clamping plate 6 gradually approaches the mold, the connecting plate 8 continues to squeeze the spring 11, and the pressure of the spring 11 pushing the top plate 10 to the mold continues to increase. When the clamping plate 6 completely clamps the mold, the squeezing of the spring 11 by the connecting plate 8 reaches the maximum, so that the pressure of the top plate 10 on the mold reaches the maximum. Through the above process, the mold can be clamped from both the horizontal and vertical surfaces at the same time.
