Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe technology, specifically to an automatic demolding system for fiberglass pipes. Background Technology

[0002] Fiberglass reinforced plastic (FRP) pipes are lightweight, high-strength, and corrosion-resistant non-metallic pipes. They are made by winding glass fibers with a resin matrix layer by layer onto a rotating mandrel according to process requirements, with silica sand evenly distributed between the fibers as a reinforcing layer. Their pipe wall structure is rationally designed and advanced, fully utilizing the material's properties. While meeting strength requirements, it improves rigidity, ensuring product stability and reliability. FRP pipes with reinforcing sand are widely accepted by users due to their excellent chemical corrosion resistance, lightweight and high strength, non-scaling properties, strong seismic resistance, longer service life compared to ordinary steel pipes, lower overall cost, quick installation, and safety and reliability.

[0003] After the fiberglass pipe is formed, the pipe body needs to be separated from the mold. For example, Chinese utility model patent CN215039449U discloses an "automatic demolding device for fiberglass pipes," which includes a base plate, a vertical plate fixed to the upper end of the base plate, a horizontal plate fixed to the vertical plate, an installation groove at the lower end of the horizontal plate, a clamping assembly inside the installation groove, a moving assembly below the horizontal plate, a mold outside the moving assembly, and a pipe body outside the mold. The advantages of this utility model are: the use of limit blocks one and two allows for limiting from both sides of the mold; by driving the threaded cylinder to rotate, the screw can be moved, separating the mold from the pipe body; and the clamping assembly makes the separation process more stable. This solution automates the demolding process and reduces labor costs. However, there are also some drawbacks: as the mold gradually separates from the tube, the weight of the part of the mold that is separated from the tube becomes greater and greater, which can easily damage the lower right side of the tube, causing the tube to deform and produce defects. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic demolding system for fiberglass pipes, which can solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic demolding system for fiberglass pipes includes two parallel support platforms. A mold is provided on the top of the two support platforms, and a pipe body is provided on the outside of the mold. A power mechanism is provided on one side of the pipe body and is mounted on a workbench. A conveyor is provided on the other side of the pipe body, and a traction vehicle is provided on the side of the conveyor away from the pipe body. The traction vehicle is slidably mounted on a guide rail.

[0014] 2. This utility model has a detection switch installed on the front side of the tractor. When the detection switch detects that the mold has arrived on the tractor, the cylinder extends and drives the anti-slip plate to move up until it contacts the bottom surface of the mold, which helps to increase the stability of the mold during traction.

[0015] 3. This utility model uses a limiting mechanism at one end of the tube to fix the tube and prevent it from moving, which would affect the demolding effect. Attached Figure Description

Detailed Implementation

[0021] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0022] like Figures 1 to 2 As shown, this utility model discloses an automatic demolding system for fiberglass pipes, including two parallel support platforms 1. A mold 2 is mounted on the top of each support platform 1, and a pipe body 3 is mounted on the outer side of each mold 2. A power mechanism is located on one side of each pipe body 3 and is mounted on a worktable 4. The power mechanism includes a motor 8, with a threaded cylinder 9 connected to the output shaft of the motor 8. A lead screw 10 is threaded into the threaded cylinder 9, and a limiting rod 11 is located at the bottom of the outer end of the lead screw 10. The limiting rod 11 is slidably connected to a limiting groove 12 on the top surface of the worktable 4, and the length of the limiting groove 12 is greater than the stroke of the lead screw 10 within the threaded cylinder 9. In application, the motor 8 actuates, causing the threaded cylinder 9 to rotate, which moves the lead screw 10 to the right, thereby pushing the mold 2 to move and separating the mold 2 from the pipe body 3.

[0023] A conveyor 5 is provided on the other side of the tube 3, and a traction vehicle 6 is provided on the side of the conveyor 5 away from the tube 3. The traction vehicle 6 is slidably mounted on the guide rail 7. A detection switch 13 is provided at the front end of the traction vehicle 6, and a cylinder 14 is provided at the rear end. An anti-slip plate 15 is connected to the piston rod of the cylinder 14. When the mold 2 moves out of the end of the tube 3 under the push of the lead screw 10, it is first conveyed to the traction vehicle 6 via the conveyor 5. After the detection switch 13 senses the mold 2, the control system controls the cylinder 14 to extend, driving the anti-slip plate 15 to move upward until it is in contact with the bottom surface of the mold 2. Under the pull of the traction vehicle 6, the mold 2 gradually separates from the tube 3. The anti-slip plate 15 helps to enhance the stability of the mold 2 when it is pulled.

[0024] Furthermore, in this embodiment, the top surfaces of the support platform 1, the conveyor 5, and the tractor 6 are all provided with V-shaped grooves, and the bottom of the V-shaped groove of the conveyor 5 is provided with a conveyor wheel 16, which facilitates the conveying of the mold 2 to the tractor 6.

[0025] Furthermore, in this embodiment, a limiting mechanism is provided on the outer side of the tube body 3 near the conveyor 5. The limiting mechanism includes a limiting frame 17, on which four cylinders 18 are provided. Each of the piston rods of the four cylinders 18 is provided with a limiting head 19. By setting the cylinders 18 and the limiting heads 19, the tube body 3 is fixed, preventing the tube body 3 from moving and affecting the demolding effect.

[0026] Working principle: In use, firstly, cylinder 18 is activated, driving the limiting head 19 to move towards the end of the tube 3 to limit the movement of the tube 3; then, motor 8 is activated to drive the threaded cylinder 9 to rotate, realizing the movement of the lead screw 10. The lead screw 10 pushes the mold 2 to the right. After the mold 2 moves onto the conveyor 5, it continues to be conveyed onto the traction vehicle 6 under the action of the conveyor wheel 16. When the mold 2 reaches the traction vehicle 6, the detection switch 13 senses the signal. At this time, cylinder 14 is activated, driving the anti-slip plate 15 to move upward until it contacts the bottom surface of the mold 2. Under the traction of the traction vehicle 6, the mold 2 continues to be pulled until it is completely pulled out of the tube 3. During the pulling process, the conveyor 5 always supports and conveys the mold 2 to prevent the mold 2 from damaging the end of the tube 3.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
