Vertical plates 602 are fixedly installed at both ends of the top of the lifting plate 601, and a rotating rod 603 is rotatably connected between the two groups of vertical plates 602 through bearings.

[0032] Working principle: When in use, concrete slurry is injected into the mold 1, an external power supply is connected, and then the vibration motor 201 is started through the controller to drive the mold 1 to vibrate. When the mold 1 vibrates, it drives the sliding sleeve 203 to slide along the T-shaped fixing rod 202 and compresses or stretches the return spring 204, which can play a buffering role for the mold 1 when it shakes, not only effectively reducing the air mixed inside, but also increasing the density of the concrete precast parts.

At this time, the servo motor 4042 is started. When the servo motor 4042 is working, it drives the driving pulley 4044 to rotate through the driving shaft 4043. The driving pulley 4044 rotates and drives the driven pulley 4046 to rotate through the connecting belt 4047.
