The nozzle body is connected to the flow channel inside the nozzle base, which improves working efficiency.

[0003] Existing technologies, such as CN213260863U, include a multi-head hot runner nozzle where the molten fluid of the hot runner is introduced into the columnar chamber of the distributor, and then distributed to each sector chamber through the distribution port on the inner cylinder, and finally ejected through the nozzle at the bottom of each sector chamber, making the product more widely applicable.

[0004] However, this nozzle still has some shortcomings in its use:

[0005] 1. The nozzle is not easy to adjust in angle during use, which to some extent limits its application flexibility in complex molds and cannot meet the injection molding requirements of different molds. Adjusting the nozzle angle is crucial.

[0006] 2. The liquid leading to the nozzle cannot be heated, which affects the temperature uniformity of the molten fluid, resulting in unstable quality of the injection molded products. It cannot ensure that the molten fluid maintains a constant temperature during the flow process, thus reducing the quality of the injection molded products. Utility Model Content

[0028] The design of the movable groove 11 and the spherical connection 12 allows the nozzle 6 to be finely adjusted within a certain range to adapt to different molds and injection molding requirements.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the connecting base 5 extends into the mounting slot 18 and engages with it. A nozzle 6 is fixedly connected to the bottom of the connecting base 5, and the nozzle 6 communicates with the guide tube 14. A sealing plate 19 is fixedly connected to the top edge of the connecting base 5, and the sealing plate 19 abuts against the mounting plate 1. A connecting line 7 is provided on the side of the mounting plate 1, which passes through the mounting plate 1 and is fixedly connected to the heating wire 17. A protective cap 8 is engaged on the side of the connecting line 7. A fixing rod 10 is provided on the side of the fixing plate 3, which passes through the fixing plate 3 and abuts against the ball connection 12.
