[0002] The production process of optical cables involves the extrusion of raw materials. In the extrusion process, the quality of the die and the mold directly affects the quality, production capacity, and cost, and also affects the product quality of the optical cable.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: currently, conventional extruder heads only have internal heating systems or external heating systems. The temperature of the head body increases with the power of the heating system, but with the set temperature of the extruder and the heat transfer of the rubber, the temperature of the extruder head body will increase, and it is necessary to adjust the extrusion speed and the external air cooling method to adjust the temperature of the extruder head body. Therefore, the result is that it is difficult to control the body temperature and it is difficult to set the extrusion production parameters.

[0004] To this end, we proposed an automatic cooling and elastic fine-tuning die for optical cables to solve the problems existing in the functions of similar U14 extruder dies on the market: the temperature of the die and the mold itself is difficult to control, and the quality control of the extruded products is more complicated.

[0005] The main purpose of the utility model is to provide an optical cable automatic cooling elastic fine-tuning die head. In actual work, an air cooling channel is provided to cool the die body, so that the mold temperature of the extruder die can be better controlled to achieve a constant temperature effect, making the quality of the extruded product more stable, and effectively solving the problems in the background technology.

[0008] A conical glue feed diverter is connected to one side of the machine head body, an opening for installing the conical glue feed diverter is provided on the machine head body, and the opening of the machine head body on the side where the conical glue feed diverter is located is closed by a cooling cover plate, a mold core is provided inside the machine head body, and the mold core is tightly installed with the front section of the conical glue feed diverter through a conical surface, and a deviation adjustment sleeve is fixed to the bottom of the machine head body in a threaded manner;

[0009] The cooling cover is locked and fixed to the machine head body by screws to form an air passage. Air passage holes are evenly distributed in the machine head body to form an air circuit, which includes an air inlet and an air outlet.

[0010] As a preferred embodiment, the conical glue inlet diverter is installed tightly to the head body through the conical surface and fixed with No. 1 screws.

[0014] As a preferred embodiment, support rod sleeves are installed on the two extended air pipe joints.

[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] The optical cable automatically cools down and fine-tunes the head with elastic force.

[0017] Compared with the current conventional extruder heads, the advantages are as follows: an internal heating system and an external heating system are provided on the main body of the head. The internal heating system includes two extended air pipe joints, and the external heating system includes a main heating ring. Airway holes are evenly distributed in the main body of the head to form an air circuit. The air circuit includes an air inlet and an air outlet.
