[0002] There are two types of filter pipes, namely concrete well pipes and reinforced concrete well pipes. Holes for water filtration need to be made on the pipe body of the filter pipe. The method of making holes is mostly the in-mold placement method, and a small amount is the out-of-mold insertion method. The in-mold placement method for making concrete filter pipes is to use bolts inserted from outside the mold to fix the module strips and modules inside the well pipe mold. The out-of-mold insertion method is to open holes in the well pipe mold and insert iron pins into the well pipe mold from outside the well pipe mold. After centrifugal molding, the iron pins are withdrawn. These methods often require corresponding forming devices to complete during implementation. However, when the existing devices are applied, the work is cumbersome. Some holes for inserting bolts are made on the mold, which is prone to slurry leakage, the hole opening rate is low, the pin insertion is cumbersome, the filter pipe molds cannot be interchanged, affecting the appearance neatness and beauty of the filter pipes, and reducing the overall strength.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0024] Please refer to Figures 1-4, a forming device for concrete and reinforced concrete filter pipe molds, including an outer shell main body 1. Inside the outer shell main body 1, a precast well pipe mold 2 is fixed. At the top of the outer shell main body 1, a top cover 3 is fixed by screws. On one side of the outer shell main body 1, a mating closing lock rod 5 and an auxiliary multiple closing lock 6 are fixed. The auxiliary multiple closing lock 6 is rotatably connected to the outer shell main body 1, and one end of the auxiliary multiple closing lock 6 is clamped with the mating closing lock rod 5. At the bottom end of the mating closing lock rod 5, a closing locking block 4 is fixed, which is convenient for completing the processing seal of the device and avoiding slurry leakage after grouting;

[0025] At one end of the outer surface of the outer shell main body 1, an integrated control box 16 is fixed. On one side of the outer surface of the outer shell main body 1, a stepping motor 7 is also fixed. On the circumferential side of the outer shell main body 1, a plurality of filter hole cylinder opening structures 14 are fixed. Inside the integrated control box 16, there are control buttons and a PLC programming controller. The PLC programming controller is electrically connected to the control buttons, the stepping motor 7, and the derivation driving cylinder 10. The filter hole cylinder opening structure 14 includes a cylinder seat 8, a guiding and limiting rod 9, a derivation driving cylinder 10, a piston push rod 11, a hole mold 12, and a tapered opening end block 13. One end of the cylinder seat 8 is fixedly connected to the derivation driving cylinder 10 by bolts. The output end of the derivation driving cylinder 10 is fixedly connected to the piston push rod 11. One end of the piston push rod 11 is welded to the hole mold 12. The top and bottom ends of the hole mold 12 are welded to the guiding and limiting rod 9. The guiding and limiting rod 9 is slidably connected to the cylinder seat 8. One end of the hole mold 12 is welded to the tapered opening end block 13, which is convenient for completing convenient and uniform air pressure pushing for opening and pulling out through integrated overall control;

[0026] On the circumferential side of the precast well pipe mold 2, a plurality of hole seat positioning rings 15 are fixed. The axis of the hole seat positioning ring 15 is the same as that of the tapered opening end block 13. The tapered opening end block 13 is connected to the precast well pipe mold 2 through the hole seat positioning ring 15. The material of the hole seat positioning ring 15 is polytetrafluoroethylene. A limiting through hole is opened inside the hole seat positioning ring 15. The maximum diameter of the limiting through hole and the tapered opening end block 13 is in transition fit, which is convenient for using the good self-lubricity and sealing performance of the material of the hole seat positioning ring 15 to complete the guiding fit for the introduction of the tapered opening end block 13 and the airtight sealing after introduction, ensuring the opening direction and avoiding slurry leakage during the opening process;

[0027] Two guiding holes are opened inside the cylinder seat 8. The axis of the opened guiding holes is the same as that of the guiding and limiting rod 9. The guiding holes and the guiding and limiting rod 9 are in clearance fit, which is convenient for forming good driving guiding stability and avoiding the misalignment of the opening position of the tapered opening end block 13 caused by the force offset when the hole mold 12 receives the driving force transmitted by the piston push rod 11, and improving the opening rate;

[0028] One end of the cylinder seat 8 is attached to the outer surface of the outer housing body 1. The cylinder seat 8 and the outer housing body 1 are connected by welding, which is convenient for positioning and installing the driving cylinder 10;

[0029] The outer shape of the tapered opening end block 13 is a frustum of a cone. The material of the tapered opening end block 13 is Q235A, and the surface of the tapered opening end block 13 is plated with chromium metal, which is convenient for forming good introduction hardness by using the material and the metal coating on its outer surface, so as to facilitate better opening of holes;

[0030] The height of the prefabricated well pipe mold 2 is 2018.5 mm. In other embodiments, the height of the prefabricated well pipe mold 2 can also be other heights, and will not be listed one by one here;

[0031] A plurality of support brackets are fixed at the bottom end of the outer housing body 1. The top end of the support bracket is attached to the bottom end of the outer housing body 1. The support bracket and the outer housing body 1 are connected by welding, which is convenient for supporting the whole device and preventing the device from shifting during the processing.

[0032] Working principle: By opening the closing lock block 4 and the auxiliary multiple closing locks 6, the outer restraint of the outer housing body 1 of the device is cancelled, and the top cover 3 is opened, so that the prefabricated well pipe mold 2 is exposed, which is convenient for grouting into the prefabricated well pipe mold 2. After grouting, it is closed again to complete the closing of the device, which is beneficial to the processing of the pipe body. Driven by the integrated control of the integrated control box 16, the external shape foundation plasticity of the filter pipe is completed. When the pipe body is not completely hardened, after controlling the air supply, the driving cylinder 10 drives the piston push rod 11 to complete the output of the driving force, so that the hole mold 12 is stressed. Cooperating with the sliding displacement of the guiding and limiting rod 9 at the guiding hole opened at the cylinder seat 8, the stroke limit of the displacement of the hole mold 12 is completed to avoid force obstruction. Cooperating with the limiting fit of the hole seat positioning ring 15 for the tapered opening end block 13, the tapered opening end block 13 is convenient for guiding out of the inside of the prefabricated well pipe mold 2 to complete convenient hole opening on the surface of the pipe body. During the hole opening process, due to the sealing and lubricity of the hole seat positioning ring 15, it is ensured that good sealing is formed after the tapered opening end block 13 is introduced, and the outflow of the internal slurry is avoided. Since the tapered opening end block 13 is a pushing-in type hole opening method, the inner surface roughness of the hole opening is low and the appearance is cleaner. And due to the pushing linkage of the filter hole cylinder hole opening structure 14, the prefabricated well pipe mold 2 is still convenient to use after changing the model, and the waste of the hole opening structure is avoided. After the pipe body is manufactured, driven by the reset of the driving cylinder 10, the tapered opening end block 13 is directly pulled out of the prefabricated well pipe mold 2 and the inside of the pipe body to complete the demoulding of the hole opening position, which is more convenient to use.
