[0023] On the basis of the first embodiment, Figure 1 As shown, a first spring 14 is sleeved on the guide rod 10 , and the first spring 14 is located between the mounting plate 11 and the push plate 9 .

[0024] In an embodiment of the present application, a first spring 14 is sleeved on the guide rod 10. Under the action of the first spring 14, the push plate 9 is prevented from extending into the corresponding through groove 4 without being acted upon by external force, thereby facilitating the addition of concrete into the through groove 4.

[0025] Embodiment 3

[0026] On the basis of the first embodiment, Figure 1 , Figure 2 As shown, the output end of the hydraulic rod 5 is connected to the lifting plate 6 through a buffer mechanism, and the buffer mechanism includes a first plate body 15 connected to the output end of the hydraulic rod 5, and a plurality of evenly distributed telescopic rods 16 are arranged on the top of the first plate body 15, and the telescopic rods 16 are all connected to a second plate body 17, and the second plate body 17 is connected to the lifting plate 6, and a second spring 18 is sleeved on the telescopic rod 16.

[0027] In the embodiment of the present application, the lifting plate 6 is connected to the output end of the hydraulic rod 5 through a buffer mechanism. The function of the buffer mechanism is that when the hydraulic rod 5 drives the lifting plate 6 to move to the first position, the second spring 18 changes from the extreme compression state to the at least partially released state, so that the bottom of the installation groove is always in contact and extruded with the mold body 3. At this time, force can be applied to move the lifting plate 6 downward in the vertical direction so that the air pressure inside and outside the through groove 4 is consistent, and then force is applied to push the push plate 9 to move downward in the vertical direction to drive the extrusion plate 13 to contact and extrude the concrete block in the through groove 4, so that the concrete block in the through groove 4 falls from the through groove 4 into the installation groove.
