[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1-4 A mold for manufacturing composite floor slabs includes a base 1, with legs 2 fixed to the upper end of the base 1, and support plates 12 connected to the upper ends of the four legs 2. A forming hole is provided in the middle of the support plate 12, a demolding component is provided at the forming hole, and a side mold structure is provided at the upper end of the forming hole.

[0024] The side mold structure includes a first side plate 9 disposed at opposite ends of the forming hole and located above the forming hole, a second side plate 14 disposed between the two ends of the two first side plates 9, and a latch 17 disposed at both ends of the first side plates 9, and the two ends of the second side plate 14 respectively latched into the two latches 17.

[0025] A snap-fit ​​structure and a positioning structure are provided between the support plate 12 and the two first side plates 9.

[0026] The demolding assembly includes a support plate 15 movably disposed at the molding hole, hydraulic push rods 3 installed between the four corners of the lower end face of the support plate 15 and the base 1, and an electromagnetic vibrator 13 installed in the middle of the lower end face of the support plate 15.

[0027] The snap-fit ​​structure includes a slot 16 located in the middle of one side of the top of the first side plate 9, a fixing block 4 fixed on the upper side of the support plate 12, an electric push rod 5 fixed on one side of the fixing block 4, a support block 7 located on the upper end of the support plate 12 and on one side of the fixing block 4, a movable rod 6 slidably inserted on the support block 7, one end of the electric push rod 5 connected to one end of the movable rod 6, and the other end of the movable rod 6 connected to a snap-fit ​​block 8, which forms a snap-fit ​​engagement with the slot 16.

[0028] The positioning structure includes positioning holes 10 symmetrically arranged on the first side plate 9, and a positioning pin 11 is provided on the upper end surface of the support plate 12. The positioning pin 11 and the positioning hole 10 form an insertion fit.

[0029] An L-shaped insert rod 20 is provided on one side of the second side plate 14, and a plug hole 19 is provided on the support plate 12. The vertical section of the L-shaped insert rod 20 and the plug hole 19 form a plug-in fit.

[0030] Place the second side plate 14 on the support plate 12, and insert the L-shaped rod 20 on the second side plate 14 into the insertion hole 19. Then place the first side plate 9 on the support plate 12, so that the positioning pin 11 on the support plate 12 is inserted into the positioning hole 10 on the first side plate 9. At the same time, the snap-fit ​​17 at the end of the first side plate 9 is snapped into the end of the second side plate 14, thus completing the splicing of the side mold. The electric push rod 5 pushes the movable rod 6 and the snap-fit ​​block 8 towards the first side plate 9, so that the snap-fit ​​block 8 is snapped into the snap-fit ​​groove 16 of the first side plate 9, thereby achieving the fixed positioning of the side mold.

[0031] After pouring concrete at the forming hole, the electromagnetic vibrator 13 is turned on to drive the support plate 15 to vibrate for a period of time, which helps to vibrate the concrete evenly and eliminate air bubbles. After the composite floor slab is formed and solidified, the electromagnetic vibrator 13 is turned on again to help to vibrate and dislodge the contact part between the composite floor slab and the side formwork. The hydraulic push rod 3 pushes the support plate 15 upward and away from the forming hole, thereby achieving demolding.

[0032] Example 2 is an optimization based on Example 1, specifically:

[0033] The upper surface of the support plate 15 is provided with positioning grooves 18 at equal intervals. By placing stones for casting concrete on the positioning grooves 18 and placing steel mesh on the stones, the steel mesh is ensured to be located inside the concrete after the concrete is poured by the support of the stones.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
