A first chute 5 is formed on the left side of the second sliding column 6. The design of the first chute 5 is to limit the movement track of the fixed block 4. The outside of the fixed block 4 is slidably connected to the inside of the first chute 5. A top block 7 is fixedly connected to the top of the second sliding column 6. The design of the top block 7 is to fix the device.

[0027] Refer to Figure 3 , 4 As shown in the figure, a limiting groove 8 is formed on the right side of the lower manifold plate 1. The design of the limiting groove 8 is to protect the internal structure. The outside of the first sliding column 2 is slidably connected to the inside of the limiting groove 8. The right side of the first sliding column 2 is slidably connected to the left side of the second sliding column 6. A spring 9 is arranged inside the limiting groove 8. The design of the spring 9 is to reset the first sliding column 2. One side of the spring 9 is fixedly connected to the inside of the limiting groove 8, and the other side of the spring 9 is fixedly connected to the rear side of the first sliding column 2. A limiting component is arranged on the front side of the lower manifold plate 1. The limiting component includes a second chute 10. The outside of the second chute 10 is formed on the front side of the lower manifold plate 1. A limiting block 11 is slidably connected to the inside of the second chute 10. The design of the second chute 10 is to fix the limiting block 11. The design of the limiting block 11 is to limit the first sliding column 2 to prevent the first sliding column 2 from popping out automatically. A first fixing groove 12 is formed on the left side of the first sliding column 2. The design of the first fixing groove 12 is to fix the limiting block 11.

[0028] Refer to Figure 3 , 6As shown in the figure, a connecting plate 14 is fixedly connected to the left side of the top of the lower flow dividing plate 1. The top of the connecting plate 14 is slidably connected to an upper flow dividing plate 15. The connecting plate 14 is designed to limit the upper flow dividing plate 15. A second fixing groove 13 is provided at the bottom right of the upper flow dividing plate 15. The second fixing groove 13 cooperates with the top block 7 to install and disassemble the upper flow dividing plate 15. An injection pipe 16 is fixedly connected to the top of the upper flow dividing plate 15. Flow dividing pipes 17 are fixedly connected to both the left and right sides of the injection pipe 16. A flow dividing pipe 18 is fixedly connected to the bottom of the flow dividing pipe 17. The flow dividing pipe 17 cooperates with the flow dividing pipe 18 to enable the internal injection material to flow out smoothly. An electric heating wire 19 is provided outside the flow dividing pipe 18. The electric heating wire 19 is designed to heat the injection material to prevent the flow dividing pipe 18 from being blocked. A first heat insulation layer 20 is fixedly connected to the outside of the flow dividing pipe 18. The material of the first heat insulation layer 20 is ceramic fiber material.

[0029] Compared with some existing technologies, the above content can enable the device to disassemble and repair the flow dividing plate during use while insulating the internal injection material to prevent blockage of the nozzle due to excessive cooling.

[0030] Working principle: When the staff uses the device, the upper flow dividing plate 15 is engaged with the connecting plate 14 inside the lower flow dividing plate 1 for preliminary limiting. At this time, the sliding column 1 is pulled, so that the fixing block 4 on the sliding column 1 slides inside the sliding column 2. Due to the shape design of the fixing block 4, the sliding column 2 moves upward inside the lower flow dividing plate 1, thereby driving the top block 7 to engage with the second fixing groove 13 inside the upper flow dividing plate 15, so as to fix the upper flow dividing plate 15. The upper flow dividing plate 15 is further fixed by screwing the bolt 23. The limiting block 11 inside the second sliding groove 10 is pulled out and snapped into the first fixing groove 12 inside the sliding column 1 to prevent the sliding column 1 from popping out automatically. After installing the upper flow dividing plate 15, the staff injects the injection material into the injection pipe 16. The injection material flows into the flow dividing pipe 18 through the flow dividing pipe 17. The electric heating wire 19 heats the injection material. The second heat insulation layer 21 and the nozzle 22 are used in cooperation to prevent the internal material from cooling too quickly, thereby preventing the injection material from blocking the nozzle 22.
