Cement pipes are also known as cement pressure pipes and reinforced concrete pipes. They can be used as underground water pipes in urban construction foundations, for sewage drainage, flood control drainage, as well as water supply pipes used in some special factories and mines and farm machine wells. The production process of drainage pipes is relatively... The demoulding stage of drainage pipes is particularly important. With the continuous increase in the demand for drainage pipes, various equipment for producing drainage pipes have emerged, such as an auxiliary demoulding device for the production of reinforced concrete drainage pipes.

[0003] At present, the auxiliary demoulding devices for reinforced concrete drainage pipes on the market mainly focus on improving the stable separation of the mold from the drainage pipe. The existing auxiliary demoulding devices for drainage pipes generally consist of an electric hydraulic sliding table, an inner mold part, an outer mold part, and a lifting mechanism. After the drainage pipe is formed, the outer mold part is pulled open by the electric hydraulic sliding table to expose the drainage pipe, and then the drainage pipe is lifted out from the inner mold part. Although the drainage pipe can be successfully demoulded after being formed, during the process of lifting out the drainage pipe, since the inner mold part fits tightly with the inner wall of the drainage pipe and is difficult to pull, the drainage pipe is easily damaged. Therefore, an auxiliary demoulding device for the production of reinforced concrete drainage pipes is proposed, which can shrink the mold during demoulding, reduce the contact surface between the mold and the drainage pipe, and avoid the difficulty of the mold to be demoulded.

[0005] To achieve the above-mentioned purpose of being able to shrink the mold during demoulding, reduce the contact surface between the mold and the drainage pipe, and avoid the difficulty of the mold to be demoulded during demoulding, the utility model provides the following technical solution: an auxiliary demoulding device for the production of reinforced concrete drainage pipes, including an electric hydraulic sliding table, and a demoulding mechanism is arranged on the top of the electric hydraulic sliding table;

[0006] The demolding mechanism includes an outer forming plate, a fixed forming plate, a movable forming plate, a fixed column, a movable rod, a driving motor, a movable column, a fixed plate and a controller. There are two outer forming plates arranged on the top of the electric hydraulic sliding table. Four fixed forming plates are fixedly installed on the top of the electric hydraulic sliding table.

Then, the driving motor rotates counterclockwise to drive the movable column and the fixed plate to rotate. The movable forming plates are pulled inward along the guide rails through the fixed plate and the movable rod. The four movable forming plates respectively rotate around the fixed columns and then leave the inner wall surface of the drain pipe, so that the contact surface with the drain pipe is greatly reduced, making it easier to demold the drain pipe. Finally, a crane is used to lift the drain pipe out along the fixed forming plate. This demolding mechanism can contract the mold during demolding, which is beneficial to reducing the contact surface between the mold and the drain pipe and facilitating demolding.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1-5 , an auxiliary demolding device for the production of reinforced concrete drain pipes in this embodiment, including an electric hydraulic sliding table 1, and a demolding mechanism 2 is arranged on the top of the electric hydraulic sliding table 1;

[0022] The demolding mechanism 2 includes an outer forming plate 201, a fixed forming plate 202, a movable forming plate 203, a fixed column 204, a movable rod 205, a driving motor 206, a movable column 207, a fixed plate 208 and a controller 209. Two outer forming plates 201 are arranged on the top of the electric hydraulic sliding table 1, four fixed forming plates 202 are fixedly installed on the top of the electric hydraulic sliding table 1, four movable forming plates 203 are arranged on the top of the electric hydraulic sliding table 1, four fixed columns 204 are fixedly installed on the top of the electric hydraulic sliding table 1, movable rods 205 are arranged outside the four movable forming plates 203, a driving motor 206 is fixedly installed on the top of the electric hydraulic sliding table 1, a movable column 207 is arranged at the output end of the driving motor 206, four fixed plates 208 are fixedly installed on the outside of the movable column 207, and a controller 209 is fixedly installed on the top of the electric hydraulic sliding table 1.

[0023] In the case implementation, inclined surface 1 - 5 is provided on the outside of the four fixed forming plates 202, and inclined surface 2 - 501 adapted to the four inclined surface 1 - 5 is respectively provided on the outside of the four movable forming plates 203. By setting the four inclined surface 1 - 5 and the four inclined surface 2 - 501, when it is necessary to form a drain pipe, the four inclined surface 1 - 5 are respectively attached to the four inclined surface 2 - 501, which is beneficial to reducing the flow marks after the drain pipe is formed.

[0024] In the case implementation, four guide rails 6 are provided on the top of the electro - hydraulic slide 1, and sliders adapted to the four guide rails 6 are respectively fixedly installed on the outside of the four movable forming plates 203. By setting the four guide rails 6 and the four sliders, when the four movable forming plates 203 move, they can move along the four guide rails 6 respectively, avoiding collision.

[0025] In the case implementation, two cover plates are hinged to the top of the two outer forming plates 201 respectively. By setting the two cover plates, when the drain pipe is formed, the top of the drain pipe can be covered to prevent sundries from falling into the drain pipe, resulting in problems with the quality of the formed drain pipe.

[0026] In the case implementation, the controller 209 is electrically connected to all the electronic components in this patent through wires, so as to control all the electronic components in this patent by operating the controller 209.

[0027] During implementation, the operations are carried out according to the following steps:

[0028] 1) When it is necessary to demold, first start the electro - hydraulic slide 1 through the controller 209, and pull the two outer forming plates 201 to the left and right sides;

[0029] 2) Then drive the motor 206 to rotate counter - clockwise to drive the movable column 207 and the fixed plate 208 to rotate;

[0030] 3) Then pull the movable forming plate 203 to slide inwards along the guide rail 6 through the fixed plate 208 and the movable rod 205;

[0031] 4) Finally, after the four movable forming plates 203 contract, the contact surface with the drain pipe is greatly reduced, making it easier to take out the drain pipe. Finally, use a crane to lift the drain pipe out along the fixed forming plates 202.

[0032] In summary, for the auxiliary demoulding device for the production of reinforced concrete drain pipes, by setting the demoulding mechanism 2, when demoulding is required, the electric hydraulic sliding table 1 is started through the controller 209, and the two outer forming plates 201 are pulled out to the left and right sides. Then, the driving motor 206 rotates counterclockwise to drive the movable column 207 and the fixed plate 208 to rotate. The movable forming plate 203 is pulled by the fixed plate 208 and the movable rod 205 to slide inward along the guide rail 6. The four movable forming plates 203 respectively rotate around the fixed column 204 and then leave the inner wall surface of the drain pipe, so that the contact surface with the drain pipe is greatly reduced, making it easier to demould the drain pipe. Finally, a crane is used to lift the drain pipe out along the fixed forming plate 202. This demoulding mechanism 2 can contract the mould during demoulding, which is beneficial to reducing the contact surface between the mould and the drain pipe and facilitating demoulding.
