Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3, A mold for conveniently demolding a reinforced concrete pipe in this embodiment includes a mounting base 1. A first cylinder 2 is connected to the inner side of the mounting base 1. An outer mold mechanism 3 is connected to one side of the first cylinder 2. The outer mold mechanism 3 includes an outer mold barrel plate 301. The outer mold barrel plate 301 is connected to one side of the first cylinder 2. A first electric heating plate 302 is connected to the outer side of the outer mold barrel plate 301. A second cylinder 4 is connected to the inner side of the mounting base 1. An inner mold mechanism 5 is connected above the second cylinder 4. The inner mold mechanism 5 includes a mounting plate 501. The mounting plate 501 is connected above the second cylinder 4. A material injection port 502 is formed inside the mounting plate 501. A motor 503 is connected above the mounting plate 501. An inner mold barrel 504 is connected to the output shaft of the motor 503. A second electric heating plate 505 is connected to the inner side of the inner mold barrel 504.

[0022] In the case implementation, the mounting base 1 is U-shaped. The number of the first cylinders 2 and the outer mold barrel plates 301 is two each. The directions of the two outer mold barrel plates 301 are opposite. The outer mold barrel plate 301 is semi-cylindrical. The lower surface of the outer mold barrel plate 301 is attached to the inner bottom wall of the mounting base 1. The two outer mold barrel plates 301 can be combined with each other or separated by the first cylinder 2. After the two outer mold barrel plates 301 are combined, they are in a cylindrical shape, which is convenient for the concrete pipe to fall off from the two outer mold barrel plates 301.

[0023] In the case implementation, the material injection port 502 is located outside the inner mold barrel 504. Concrete can be injected between the two outer mold barrel plates 301 and the inner mold barrel 504 through the material injection port 502. The inner mold barrel 504 is located below the mounting plate 501. The inner mold barrel 504 can be driven to rotate by the motor 503, so as to facilitate the concrete pipe to fall off from the inner mold barrel 504.

[0024] In the case implementation, the length of the inner mold barrel 504 is the same as that of the outer mold barrel plate 301. The inner mold barrel 504 is located between the two outer mold barrel plates 301. The lower surface of the inner mold barrel 504 is attached to the inner bottom wall of the mounting base 1. The inner mold barrel 504 and the two outer mold barrel plates 301 are concentrically distributed. The upper surface of the outer mold barrel plate 301 is attached to the lower surface of the mounting plate 501. The number of the second cylinders 4 is not less than two. The inner mold mechanism 5 can be longitudinally moved by the second cylinder 4, so that the concrete pipe can fall off from the inner mold barrel 504.

[0025] During implementation, the following steps are carried out for operation:

[0026] 1) First, the two outer mold barrel plates 301 are combined with each other by the first cylinder 2;

[0027] 2) Then, the inner mold mechanism 5 is moved downward by the second cylinder 4 until the upper surface of the outer mold barrel plate 301 is attached to the lower surface of the mounting plate 501 and the lower surface of the inner mold barrel 504 is attached to the inner bottom wall of the mounting base 1;

[0028] 3) Concrete can be injected between the two outer mold cylinder plates 301 and the inner mold cylinder 504 through the material injection port 502;

[0029] 4) The drying of the concrete is accelerated by the first electric heating plate 302 and the second electric heating plate 505;

[0030] 5) The two outer mold cylinder plates 301 are separated from each other by the first air cylinder 2;

[0031] 6) Finally, the inner mold cylinder 504 is driven to rotate by the motor 503, and the inner mold mechanism 5 is moved upward by the second air cylinder 4 until the inner mold cylinder 504 falls off from the concrete pipe.

[0032] In summary, for the mold for conveniently demolding a reinforced concrete pipe, the two outer mold cylinder plates 301 are combined with each other by the first air cylinder 2, and then the inner mold mechanism 5 is moved downward by the second air cylinder 4 until the upper surface of the outer mold cylinder plate 301 fits the lower surface of the mounting plate 501, and the lower surface of the inner mold cylinder 504 fits the inner bottom wall of the mounting seat 1. Concrete can be injected between the two outer mold cylinder plates 301 and the inner mold cylinder 504 through the material injection port 502, and the drying of the concrete is accelerated by the first electric heating plate 302 and the second electric heating plate 505.

[0033] Moreover, after the concrete pipe is dried, the two outer mold cylinder plates 301 are separated from each other by the first air cylinder 2. Finally, the inner mold cylinder 504 is driven to rotate by the motor 503, and the inner mold mechanism 5 is moved upward by the second air cylinder 4 until the inner mold cylinder 504 falls off from the concrete pipe, solving the problem of cumbersome demolding.
