[0002] With accelerated urbanization, infrastructure construction, and agricultural modernization, the demand for PE pipes has surged, prompting companies to expand production. Numerous enterprises have entered the PE pipe manufacturing industry, intensifying market competition. To stand out, companies must not only ensure product quality but also continuously optimize production processes and reduce costs. Precise control of pipe wall thickness is crucial for both product quality and cost control, making advanced wall thickness adjustment devices essential for enhancing competitiveness.

[0003] The existing PE pipe mold wall thickness adjustment device usually adjusts the wall thickness of the extruded PE pipe by turning the bolt to change the size of the adjustment ring.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4This utility model provides a technical solution: a pipe wall thickness adjustment device for a PE pipe mold, including a base 1, multiple supports 2 fixedly installed on the top of the base 1, a wall thickness adjustment device body 3 fixedly installed on the top of the multiple supports 2, a core mold 4 movably installed inside the wall thickness adjustment device body 3, two first fixing frames 5 provided on the top of the base 1, a first guide rod 6 provided between the two first fixing frames 5, a first servo motor 7 installed on one side of a single first fixing frame 5, the output end of the first servo motor 7 movably passing through the single first fixing frame 5 and connected to a first lead screw 8, the first... A sliding frame 9 is provided on the outside of a guide rod 6 and a first lead screw 8. The top of one side of the sliding frame 9 is fixedly connected to the core mold 4. By setting up the core mold 4, the first lead screw 8 and the sliding frame 9, the traditional adjustment method is changed. By adjusting the position of the core mold 4 in the wall thickness adjustment device body 3, the flow path of the PE material in the wall thickness adjustment device body 3 is changed, thereby realizing the adjustment of the wall thickness of the PE pipe. The overall adjustment method does not require machine shutdown, which effectively improves the overall work efficiency. At the same time, it is not easy to generate dead corners and cavities, effectively reducing the defective product output rate and meeting the actual use requirements.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the base 1 is provided with two second fixing frames 10, and a second guide rod 11 is provided between the two second fixing frames 10. A second servo motor 12 is installed on one side of each second fixing frame 10. The output end of the second servo motor 12 passes through the single second fixing frame 10 and is connected to a second lead screw 13. A sliding seat 14 is provided on the outside of the second guide rod 11 and the second lead screw 13. A laser cutter 15 is installed on the top of the sliding seat 14. With the arrangement of the second servo motor 12, the second lead screw 13 and the laser cutter 15, the extruded PE pipe can be quickly cut, thereby ensuring the continuity of work, eliminating the need for manual operation and providing higher safety.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a cooling ring 16 is installed at the discharge end of the wall thickness adjustment device body 3. A water inlet 17 is installed at the top of the cooling ring 16, and a solenoid valve 18 is installed at the bottom of the cooling ring 16. A drain outlet 19 is connected to the bottom of the solenoid valve 18. By setting up the cooling ring 16, the water inlet 17 and the drain outlet 19, the PE pipe can be cooled when it is extruded, which can speed up the molding speed of the PE pipe and save labor and time costs.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a scale 20 is installed on one side of a single bracket 2, and movable columns 21 are symmetrically arranged on the top and bottom of the wall thickness adjustment device body 3. A connecting frame 22 is connected to the outside of each movable column 21, and a pointer 23 is connected to one end of each connecting frame 22. The pointer 23 is attached to the surface of the scale 20. Through the setting of the scale 20, movable columns 21 and pointer 23, the position change of the core mold 4 can be accurately observed, avoiding the situation of uneven wall thickness of PE pipe.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the top and bottom of the wall thickness adjustment device body 3 are symmetrically provided with U-shaped frames 24. Each U-shaped frame 24 is equipped with an adjusting bolt 25 on its top. One end of each adjusting bolt 25 is movably inserted through a corresponding U-shaped frame 24 and attached to one end of a corresponding movable column 21. Through the arrangement of the U-shaped frame 24 and the adjusting bolt 25, the position of the core mold 4 can be finely adjusted, thereby improving the accuracy of wall thickness adjustment and ensuring the uniformity of the wall thickness of the PE pipe.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the wall thickness adjustment device body 3 is provided with an injection port 26, and fastening bolts 27 are installed at the four corners of the top of the base 1. Each fastening bolt 27 is fitted with a gasket 28 on its outer side. Through the setting of the injection port 26, PE fluid material for extrusion can be added into the wall thickness adjustment device body 3. Through the setting of the fastening bolts 27 and the gaskets 28, the device can be installed and fixed as a whole. At the same time, the gaskets 28 are used to increase the friction and prevent the fastening bolts 27 from loosening.

[0028] Working principle: In use, firstly, PE material fluid for extrusion is added into the wall thickness adjustment device body 3 through the injection port 26. Then, according to the wall thickness requirement of the PE pipe, the first servo motor 7 is started, driving the first lead screw 8 to rotate. This causes the sliding frame 9 to slide between the first guide rod 6 and the first lead screw 8, which in turn drives the mandrel 4 to slide within the wall thickness adjustment device body 3. This adjusts the flow path of the PE material fluid within the wall thickness adjustment device body 3. Simultaneously, the position changes of the two pointers 23 on the scale 20 are observed to confirm whether the position of the mandrel 4 has shifted. If a shift occurs, the corresponding adjusting bolt is tightened. 25. The adjusting bolt 25 presses the movable column 21 to restore the core mold 4 to its original position. Then, cold water is added to the cooling ring 16 through the water inlet 17 to cool the extruded PE pipe. After a period of use, the solenoid valve 18 is opened to discharge the water that has risen in temperature from the cooling ring 16 through the drain outlet 19. Finally, after the PE pipe has cooled and formed, the second servo motor 12 is started to drive the second lead screw 13 to rotate, causing the sliding seat 14 to slide on the second guide rod 11 and the second lead screw 13. The laser cutter 15 quickly cuts the formed PE pipe, and the finished product is quickly collected manually.

[0029] By following the steps outlined above, you can complete the use of the pipe wall thickness adjustment device for the PE pipe mold.
