[0043] The outer positioning plate 5 is detachably mounted on the second boss 13 in the groove of the bottom mold 1. A liquid injection groove 14 is formed between the first boss 11 and the second boss 13. Liquid is injected into the liquid injection groove 14.

[0044] The buoyancy box 4 is floated in the injection tank 14, and the ends of the steel bars of the composite plate are inserted into the side openings of the buoyancy box 4. The density of the liquid injected into the injection tank 14 should be greater than the overall density of the buoyancy box 4.

[0045] The composite slab production mold adjusts the position of the inner positioning plate 2 through the adjustment mechanism 12, thereby realizing the size adjustment of the forming template 3 so as to adapt to the concrete pouring and manufacturing of composite slabs of different sizes; cooperates with the outer positioning plate 5 to position the horizontal position of the floating box 4, and the floating box 4 floats in the liquid injection tank 14 to realize the automatic leveling of the composite slab steel bars, thereby ensuring the stable forming of the steel bars, precast slabs and concrete.

[0046] The adjustment mechanism 12 includes a rotating shaft rotatably connected to the bottom mold 1, a gear 121 on the rotating shaft, and a rack 21 meshing with the gear 121.

Finally, the top sealing plate 36 is covered on the third side form 35 and the second side form 32, and concrete pouring can be carried out. The precast panels are assembled and cast together to form a composite panel, and the concrete can be poured through the top opening before the top sealing plate 36 is covered, or an opening can be designed on the peak plate 36, so that the concrete can be poured and formed after the top sealing plate 36 is covered.

[0056] In summary, due to the adoption of the above technical solution, the concrete composite slab production mold of this embodiment has the following beneficial effects compared with the prior art:
