[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a plastic pipe forming die head.

[0022] Embodiment 1:

[0023] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a plastic tube forming die head, including a die head body 100, a silicone sleeve 200, a cooling component 300 and an adjustment component 400.

[0024] Specifically, the die head body 100 includes a die base 101, a discharge pipe 103 arranged on the right side of the die base 101 and a cooling chamber 104 arranged inside the die base 101. A first mounting plate 102 is arranged on the right side of the die base 101. The first mounting plate 102 can increase the contact area between the die base 101 and the extruder for installation and disassembly. A die core 105 is arranged inside the die base 101. The discharge pipe 103 is connected to the cooling chamber 104. The cooling chamber 104 can transport cooling water to reduce the temperature and avoid the problem of damage to the silicone sleeve 200 due to long-term high temperature to prevent scalding.

[0025] Specifically, the silicone sleeve 200 is sleeved on the outside of the mold base 101, and the silicone sleeve 200 has an anti-scalding effect.

[0026] Specifically, the cooling component 300 includes a delivery pipe 301 arranged on the left side of the mold base 101, a water inlet pipe 303 arranged at the bottom of the delivery pipe 301 and a cooling groove 304 arranged on the water inlet pipe 303. Cooling water can be delivered to the cooling groove 304 through the water inlet pipe 303. The cooling water in the cooling groove 304 can reduce the temperature in the delivery pipe 301 to facilitate extrusion molding. A second mounting plate 302 is arranged on the right side of the delivery pipe 301. The second mounting plate 302 is fixedly connected to the mold base 101 by bolts. The second mounting plate 302 can increase the contact area between the delivery pipe 301 and the mold base 101 to facilitate installation and disassembly of the cooling component 300.

[0027] Specifically, the adjusting component 400 includes an adjusting tube 401 slidably connected to the conveying tube 301 and a connecting tube 403 arranged on the top of the adjusting tube 401. The right side of the connecting tube 403 is fixedly connected to the mold base 101, and the connecting tube 403 is connected to the cooling chamber 104. The cooling water in the cooling trough 304 can be transported to the cooling chamber 104 through the connecting tube 403 for cooling.

[0028] Furthermore, a tightening knob 402 is threadedly connected to the adjusting tube 401, and a first sealing ring 404 and a second sealing ring 405 are sequentially clamped on the inner wall of the adjusting tube 401. The tightening knob 402 can be loosened. After the tightening knob 402 is loosened, the adjusting tube 401 can be moved along the conveying pipe 301. After moving to a suitable position, the tightening knob 402 is tightened to adjust the cooling range according to actual needs. The use range is wide. At the same time, the first sealing ring 404 and the second sealing ring 405 can achieve a sealing effect to prevent cooling water leakage.

[0029] The working principle and use process of the utility model: when in use, since the silicone sleeve 200 wraps the outside of the mold base 101, the silicone sleeve 200 has an anti-scalding effect, and then the cooling water can be transported to the cooling groove 304 through the water inlet pipe 303, and the cooling water in the cooling groove 304 can be transported to the cooling cavity 104 through the connecting pipe 403, and finally discharged through the discharge pipe 103. In this process, the temperature of the outer surface of the mold base 101 can be reduced by cooling water, and the problem of damage to the silicone sleeve 200 caused by long-term excessive temperature can be avoided, so as to prevent scalding. When the cooling range needs to be adjusted, the fastening knob 402 of the adjustment component 400 can be loosened. After the fastening knob 402 is loosened, the adjustment tube 401 can be moved along the delivery pipe 301. After moving to a suitable position, the fastening knob 402 can be tightened to adjust the cooling range according to actual needs. The use range is large, and at the same time, the first sealing ring 404 and the second sealing ring 405 can achieve a sealing effect to prevent cooling water leakage.
