[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0020] Please refer to Figure 1-4 , the technical solution adopted by the utility model is:

[0021] A demoulding device for concrete pipe piles comprises a base, side plates are symmetrically arranged at opposite ends of the top of the base, a lower mold is rotatably connected between the two side plates, an upper mold that cooperates with the lower mold is slidably connected between the two side plates, a lifting drive component is installed between the two side plates, the lifting drive component is connected to the upper mold, and the lifting drive component drives the upper mold to slide up and down along the side plates, L-shaped connecting rods are symmetrically fixedly connected at opposite ends of the upper mold, the free ends of the L-shaped connecting rods pass through the side plates and are fixedly connected to racks, and rotating rods symmetrically fixedly connected to the side plates for rotation at opposite ends of the lower mold, the free ends of the rotating rods pass through the side plates and are installed with rotating gears that mesh with the racks.

[0022] From the above description, it can be seen that the beneficial effects of the utility model are:

[0023] In the present solution, when pouring pipe piles, the lifting drive can be used to drive the upper mold to descend and cover the lower mold, and then the casting and molding are carried out. After the molding is completed, the lifting drive drives the upper mold to slide upward. When the upper mold and the lower mold slide to a certain distance, the rack meshes with the rotating gear, so that as the upper mold slides, the lower mold can be driven to flip over for demolding and discharging, thereby realizing automatic demolding of the pipe piles and improving work efficiency.

[0024] Furthermore, the lifting drive component includes a double-headed screw rotatably connected between two side plates, wherein a driving motor is installed on one of the side plates, the driving motor is fixedly connected to the double-headed screw, and the outer walls at opposite ends of the double-headed screw are symmetrically threaded with sliders, a first hinge seat is installed at the bottom of the slider, and a second hinge seat is fixedly connected to the middle position of the top of the upper mold, and an articulated rod is hinged between the two first articulated seats and the second articulated seats.

[0025] From the above description, it can be seen that the rotation of the driving motor can drive the two sliders to slide in opposite directions, and then drive the upper mold up and down through the hinged rod to realize the opening of the upper mold. Moreover, when the pipe pile is formed, the upper mold can keep its position fixed under the interlocking action between the double-headed screw and the slider to ensure the forming effect.

[0026] Furthermore, a first limit strip is provided on the outer extension of the opening of the lower mold, and the first limit strip is provided around the opening of the lower mold, a sealing groove is provided on the top of the first limit strip, a second limit strip is provided on the outer extension of the opening of the upper mold, and a sealing strip that cooperates with the limit strip is provided on the bottom of the second limit strip.

[0027] As can be seen from the above description, during pouring, the sealing strip can be inserted into the sealing groove, thereby ensuring the sealing between the upper mold and the lower mold and preventing the slurry from flowing out.

[0028] Furthermore, a plurality of pouring pipes are connected to the top of the upper mold at equal distances.

[0029] From the above description, it can be seen that by connecting a number of pouring pipes at equal distances on the top of the upper mold, pouring inside the mold can be facilitated, and providing multiple pouring pipes can make the pouring more uniform, thereby improving the pouring efficiency and pouring effect.

[0030] Furthermore, the side plate is provided with a sliding groove that cooperates with the L-shaped connecting rod.

[0031] Furthermore, counterweight blocks are symmetrically arranged at two opposite ends of the top of the upper mold.

[0032] It can be seen from the above description that by setting the counterweight block, it is possible to ensure that the upper mold and the lower mold are closely fitted, thereby avoiding slurry leakage.

[0033] Please refer to Figures 1 to 4 As shown, the first embodiment of the utility model is:

[0034] Please refer to Figure 1 and Figure 3 , a demoulding device for concrete pipe piles, comprising a base 1, side plates 2 are symmetrically arranged at opposite ends of the top of the base 1, a lower mold 3 is rotatably connected between the two side plates 2, an upper mold 4 that cooperates with the lower mold 3 is slidably connected between the two side plates 2, a lifting drive member 5 is installed between the two side plates 2, the lifting drive member 5 is connected to the upper mold 4, and the lifting drive member 5 drives the upper mold 4 to slide up and down along the side plates 2, L-shaped connecting rods 6 are symmetrically fixed at opposite ends of the upper mold 4, the side plates 2 are provided with a slide groove 15 that cooperates with the L-shaped connecting rod 6, the free end of the L-shaped connecting rod 6 passes through the side plate 2 and is fixed with a rack 7, the lower mold 3 is symmetrically fixed with a rotating rod 8 that is rotatably connected to the side plate 2 at opposite ends, the free end of the rotating rod 8 passes through the side plate 2 and is installed with a rotating gear 9 that is meshed with the rack 7, a plurality of pouring pipes 14 are equidistantly connected to the top of the upper mold 4, and counterweights 16 are symmetrically arranged at opposite ends of the top of the upper mold 4.

[0035] Please refer to Figure 2 The lifting drive member 5 includes a double-headed screw 51 rotatably connected between the two side plates 2, a driving motor 52 is installed on one of the side plates 2, the driving motor 52 is fixedly connected to the double-headed screw 51, and the outer walls of the opposite ends of the double-headed screw 51 are symmetrically threaded with sliders 53, a first hinge seat 54 is installed at the bottom of the slider 53, a second hinge seat 55 is fixedly connected to the middle position of the top of the upper mold 4, and a hinge rod 56 is hinged between the two first hinge seats 54 and the second hinge seats 55.

[0036] Please refer to Figure 1 and Figure 4 The opening of the lower mold 3 is extended with a first limiting strip 10, and the first limiting strip 10 is arranged around the opening of the lower mold 3. A sealing groove 11 is opened on the top of the first limiting strip 10. The opening of the upper mold 4 is extended with a second limiting strip 12 that abuts against the first limiting strip 10. The bottom of the second limiting strip 12 is provided with a sealing strip 13 that cooperates with the limiting groove.

[0037] The working process of the demoulding device for concrete pipe piles is as follows:

[0038] When pouring the pipe pile, the staff starts the driving motor 52 through the external switch, and the driving motor 52 drives the double-headed screw 51 to rotate, thereby driving the two sliders 53 to slide in the direction of approaching each other, and then pushes the upper mold 4 to descend through the hinge rod 56. During the descent of the upper mold 4, the rack 7 is meshed with the rotating gear 9, driving the rotating gear 9 and the lower mold 3 to rotate in the opposite direction, so that the opening of the lower mold 3 is set upward, and then the rack 7 is disengaged from the rotating gear 9, and the upper mold 4 continues to descend to cover the lower mold 3. When covering, the sealing strip 13 of the upper mold 4 is inserted into the sealing groove 11, which can not only ensure the sealing between the upper mold 4 and the lower mold 3, but also keep the angle of the lower mold 3 fixed through the mutual cooperation of the sealing groove 11 and the sealing strip 13;

[0039] Then, the raw material is poured into the mold through the pouring pipe 14. After the pouring is completed, the pouring is stopped. After molding, the driving motor 52 is rotated in the reverse direction. The driving motor 52 drives the upper mold 4 to rise. When the upper mold 4 rises to a certain height, the rack 7 is meshed with the rotating gear 9 to drive the lower mold 3 to rotate forward and flip, so that the molded pipe pile slides out of the lower mold 3. When the pipe pile adheres to the lower mold 3, the staff can knock on the mold to assist in unloading.

[0040] To sum up, the utility model provides a demoulding device for concrete pipe piles. When the pipe piles are poured, the upper mold can be driven down and cover the lower mold by the lifting drive member, and then the pouring and molding are carried out. After the molding is completed, the upper mold is driven upward by the lifting drive member to slide. When the upper mold and the lower mold slide to a certain distance, the rack and the rotating gear are engaged, so that as the upper mold slides, the lower mold can be driven to flip over for demoulding and discharging, thereby realizing automatic demoulding of the pipe piles and improving work efficiency.
