[0029] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Referring to Figure 1 、 Figure 2 and Figure 4 , an embodiment provided by the present utility model: a PE pipe extrusion die with heat dissipation function, including a delivery pipe 1. A positioning ring 18 is slidably connected to the left inner part of the delivery pipe 1. An extrusion pipe 2 is fixedly connected to the left side of the positioning ring 18. Fixing parts 6 are fixedly connected to the front and rear sides of the outside of the delivery pipe 1. A pulling block 7 is arranged outside the fixing part 6. A connecting rod 13 is fixedly connected to the corresponding side of the pulling block 7. An insert block 16 is fixedly connected to the corresponding end of the connecting rod 13. A spring 14 is arranged outside the connecting rod 13. A middle column 3 is arranged inside the extrusion pipe 2. Water inlet and outlet assemblies are fixedly connected to the left and right sides of the front side inside the extrusion pipe 2 and the middle column 3. A slide groove 15 is opened inside the fixing part 6. The spring 14 is arranged inside the slide groove 15. The connecting rod 13 and the insert block 16 are slidably connected inside the slide groove 15. Insert holes 17 are opened on the front and rear sides inside the delivery pipe 1 and the positioning ring 18. The insert block 16 is slidably connected inside the insert hole 17;
[0031] The water inlet and outlet assembly includes a water inlet pipe 4 and a water outlet pipe 5. The water inlet pipe 4 is fixedly connected to the right side inside the extrusion pipe 2 and the middle column 3. The water outlet pipe 5 is fixedly connected to the left side inside the extrusion pipe 2 and the middle column 3.
[0032] By pulling the pulling block 7, the connecting rod 13 is driven to move, and at the same time, the inserting block 16 is driven to move away from the inserting hole 17, so that the inserting block 16 moves into the sliding groove 15 to squeeze the spring 14, and the extrusion pipe 2 is pulled, so that the positioning ring 18 moves and separates from the conveying pipe 1, which plays a role in disassembling and replacing the extrusion pipe 2, enabling it to produce PE pipes of different models; Cooling water is injected into the internal of the through groove 8 through the water inlet pipe 4 for cooling, and the cooling water flows out through the water outlet pipe 5 for cooling water circulation.
[0033] Refer to Figures 1 - 3 , a through groove 8 is provided inside the middle column 3, overflow holes 10 are evenly distributed on the front and rear sides of the through groove 8, a branch groove 9 is provided on one side of the overflow hole 10, and four blocking rings 11 are arranged inside the through groove 8; A fixed frame 12 is fixedly connected to the right side of the middle column 3, and one side of the fixed frame 12 is fixedly connected to the inner wall of the extrusion pipe 2.
[0034] The coolant injected into the through groove 8 is shunted through the overflow holes 10, so that it enters the internal of the branch groove 9, and the flow rate of the cooling water is slowed down by the blocking rings 11, reducing the heat dissipation and cooling time of the PE pipe; The middle column 3 is fixedly supported by the fixed frame 12.
[0035] Working principle: When the mold needs to be used, cooling water is injected into the through groove 8 through the water inlet pipe 4, the flow of the cooling water is blocked and slowed down by the blocking rings 11, the cooling time of the pipe is extended, and the cooling water flows to the internal of the branch groove 9 through the overflow holes 10, expanding the heat dissipation area of the pipe for cooling, realizing the expansion of the heat dissipation area of the PE pipe and the improvement of the cooling speed, improving the working efficiency; By pulling the pulling block 7, the inserting block 16 is driven to move through the connecting rod 13, separated from the inserting hole 17 and moved into the sliding groove 15 to squeeze the spring 14, the extrusion pipe 2 is pulled to drive the positioning ring 18 to move and separate from the conveying pipe 1, realizing the disassembly and replacement of the extrusion pipe 2, enabling it to produce PE pipes of different models, without replacing the whole mold, reducing the production cost.
