[0002] 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] At present, the conventional extruder head uses an adjustment screw to push the mold sleeve to achieve the adjustment purpose. This structure produces a step difference in the flow channel, which is not conducive to the flow of rubber (there will be backflow and burnt materials); due to the locking of the mold, it will be difficult to adjust the deviation; there is a gap between the mold sleeve and the head, and there is a risk of leakage.

[0004] Therefore, we propose an optical cable sheathed plastic elastic integrated fine-tuning machine head. Utility Model Content

[0005] The main purpose of the utility model is to provide an optical cable sheathing plastic elastic integrated fine-tuning machine head, which has no step difference in the flow channel, is conducive to the flow of rubber (no backflow material, burnt material phenomenon) and does not have the risk of leakage; it is convenient to adjust the deviation and the quality of the extruded product is more stable, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cable plastic sheathed elastic integrated fine-tuning machine head comprises a main body and a movement, wherein one end of the outer periphery of the main body is connected with a deflection adjusting sleeve, the deflection adjusting sleeve and the main body are arranged at a right angle, an deflection adjusting screw is installed at the end of the deflection adjusting sleeve away from the main body, an outer mold is provided inside the main body, and a mold core is provided inside the outer mold; a movement is installed at the end of the main body away from the deflection adjusting sleeve, the movement is fixedly connected to one end of the main body by a second screw, the end of the movement away from the second screw is clamped with one end of the mold core, the end of the main body away from the movement is threadedly connected with an outer mold pressure cover, a main body heating ring is sleeved on the outer periphery of the main body, and a support adapter is connected to one side of the main body.

[0008] By adopting the above technical solution, the flow channel has no step difference, which is conducive to the flow of rubber (no backflow material, burnt material phenomenon) and there is no risk of leakage; it is convenient to adjust the deviation and the quality of the extruded product is more stable.

[0009] Specifically, the deviation adjusting screw is threadedly connected to the deviation adjusting tooth sleeve, and one end of the deviation adjusting screw passes through and contacts the deviation adjusting tooth sleeve and one side of the outer mold.

[0010] Specifically, the outer mold cover is embedded in one end of the main body and is sleeved on the outer mold.

[0011] Specifically, a through hole for installing the deflection adjusting sleeve is provided on the periphery of the main heating coil near one end of the deflection adjusting screw, and one end of the deflection adjusting sleeve passes through the through hole and is threadedly connected to the main body.

[0012] Specifically, one end of the core close to the outer mold is in close contact with the interior of the main body through a tapered surface, and one end of the mold core is inserted into the core.

[0013] Specifically, the top end of the main body is connected with a flange, the bottom end of the flange is threadedly connected to the main body, and the flange is located at the neck and is wrapped with a flange heating ring.
