The lower mold 4 is arranged on the top of the vibrating table 1, and one side of the top of the lower mold 4 is in fitting connection with the upper mold 5. A plurality of rectangular grooves 14 are opened at both ends of the top of the lower mold 4, and a rectangular block 15 is snap-fitted to the inner wall of each rectangular groove 14. One side of each rectangular block 15 is fixedly connected to one side of the upper mold 5. One side of the upper mold 5 is in fitting connection with one side of the lower mold 4 through a plurality of rectangular blocks 15. Positioning holes 7 are opened at both ends of the lower mold 4 and the upper mold 5. A steel bar frame 8 is snap-fitted inside the positioning hole 7. The steel bar frame 8 is arranged in the middle of the lower mold 4 and the upper mold 5 through the positioning hole 7. Handles 6 are fixedly connected to both ends of the top of the upper mold 5.

[0026] During operation, by placing the lower mold 4 on the top of the vibrating table 1, and then placing the steel bar frame 8 inside the positioning hole 7 opened at the top of the lower mold 4. Then, through the handle 6, the upper mold 5 is placed on the top of the upper mold 5, and a plurality of rectangular blocks 15 are inserted into the inside of a plurality of rectangular grooves 14, so that the lower mold 4 and the upper mold 5 are mutually fitted, and the positioning hole 7 opened at the bottom of the upper mold 5 is also snap-fitted on the outer side of the steel bar frame 8. The fitting of the lower mold 4 and the upper mold 5 can fix the steel bar frame 8, completing the installation work of the steel bar frame 8 and preventing it from being misaligned. Then the worker injects cement concrete into the mold, starts the vibrating motor at the bottom of the vibrating table 1, drives the vibrating table 1 to start vibrating, and then uses a plurality of vibrating springs 2 to improve the vibrating effect of the vibrating table 1 and can also prevent it from being misaligned. Then, by using the base 3 and the limiting sleeves 31, the stability of the device can be improved, and by using the limiting sleeves 31, the service life of the vibrating springs 2 can be improved. And with the vibration of the vibrating table 1, the mold and the slurry can be driven to vibrate, reducing the occurrence of air bubbles inside the produced precast slabs and improving the production quality of the precast slabs. By adopting the above method, the staff can quickly install the steel bar frame 8, and it is convenient for the worker to operate, which can reduce the time and energy consumed during operation, improve the use efficiency of the device, and improve the production efficiency of the cement concrete precast slabs.

[0027] Further, as Figure 3 shown, a slot 16 is opened in the middle of each rectangular block 15, and a plug rod 13 is snap-fitted inside each slot 16. One end of each plug rod 13 is fixedly connected to the slider 12, and one end of each plug rod 13 is snap-fitted to the inner wall of one side of the rectangular groove 14 through the plug rod 13. And each rectangular block 15 is snap-fitted to the inner wall of the rectangular groove 14 through the plug rod 13.

[0028] During operation, after inserting the rectangular block 15 into the interior of the rectangular groove 14, the fixed connection between one end of the insertion rod 13 and the slider 12 is utilized. When the threaded rod 10 drives the slider 12 to move in the sliding groove 11, the insertion rod 13 will be driven to insert into the interior of the insertion slot 16. And one end of the insertion rod 13 is engaged with the inner wall of one side of the rectangular groove 14, so that the rectangular block 15 is fixed inside the rectangular groove 14. Thus, the lower mold 4 and the upper mold 5 are tightly fitted together, preventing liquid leakage during the production of precast slabs, and thereby improving the service life of the mold.

[0029] Furthermore, as Figure 4 shown, threaded rods 10 are threadedly connected to the inner walls at both ends of the lower mold 4, and a knob 9 is fixedly connected to one end of each threaded rod 10. Each threaded rod 10 rotates inside the lower mold 4 via the knob 9. A plurality of sliding grooves 11 are provided on the outer side of each threaded rod 10. The plurality of sliding grooves 11 are opened on the inner walls at both ends of the lower mold 4, and one side of each sliding groove 11 communicates with one side of a rectangular groove 14. A slider 12 is sleeved inside each sliding groove 11, the inner wall of one end of each slider 12 is threadedly connected to the outer wall of the threaded rod 10, and each slider 12 slides inside the sliding groove 11 via the threaded rod 10.

[0030] During operation, by rotating the knob 9, the threaded rod 10 can be driven to rotate on the inner walls at both ends of the lower mold 4.

Then place the upper mold 5 on the top of the lower mold 5 through the handle 6, insert multiple rectangular blocks 15 into the multiple rectangular grooves 14. By rotating the knob 9, the threaded rod 10 can be driven to rotate on the inner walls at both ends of the lower mold 4, and the slider 12 can be driven to move stably inside the chute 11. When the slider 12 moves, the insertion rod 13 will be driven to insert into the insertion slot 16, and one end of the insertion rod 13 will be engaged with the inner wall of one side of the rectangular groove 14. Thus, the rectangular block 15 is fixed inside the rectangular groove 14, and the lower mold 4 and the upper mold 5 are tightly fitted together.
