[0023] In a specific embodiment of the present invention, the vibration table body 1 is made of high-strength steel, the cover plate 5 is matched with the upper end of the vibration table body 1, and covers the upper side of the vibration table body 1, effectively reducing the noise generated during the vibration process, and the second hollow groove 12 is rectangular for placing the tray 6, and the tray 6 is used to place the mold and the clamping mechanism. The clamping mechanism, the locking assembly and the reciprocating mechanism in this device are each provided with two groups, the first bolt 601 is used for adjustment, and the first nut 602 is used to adjust the clamping force. The other side of the A spring 603 contacts the bottom of the connecting block 604, which is used to increase the height of the fixing frame 605, and can also provide the elastic force of the fixing frame 605. The connecting block 604 and the fixing frame 605 form a rotating connection for easy fixation. The fixing frame 605 is toggled to open the fixing frame 605 and place the mold carrying the cement mortar to the lower side of the fixing frame 605. The fixing frame 605 is pressed downward to fix the mold carrying the cement mortar. The return block 606 contacts the locking assembly, which is convenient for the subsequent locking assembly to limit the fixing frame 605. When the fixing frame 605 is closed, the top of the support rod 607 contacts the fixing frame 605 to support the fixing frame 605 and prevent the fixing frame 605 from tilting downward.

The support rod 607 and the limit plate 608 work together The stability and position accuracy of the mold during vibration are ensured. When the fixing frame 605 is pressed down and closed, the convex block 801 is pushed to the outside of the concave block 8 by the action of the B spring 802.
