[0021] When this utility model is in operation, the operator can use the air blowing mechanism 8 to blow water droplets on the surface of the cable into the air blowing frame 7. Under the action of the filter plate 9, the water can be filtered, improving the practicality of the device. In addition, the water can be recycled through the water return mechanism 10, which can also achieve the purpose of heat dissipation from the water, avoiding the accumulation of heat in the water and affecting the cooling effect on the cable.
[0022] The air blowing mechanism 8 includes an air pump 81 fixed to one side of the surface of the air blowing frame 7. The working end of the air pump 81 is connected to a connecting air pipe 82, which passes through the air blowing frame 7. The other end of the connecting air pipe 82 is connected to an annular pipe 83, and a plurality of air blowing heads 84 are connected to the surface of the annular pipe 83. In this embodiment, through the arrangement of the air pump 81, the connecting air pipe 82, the annular pipe 83 and the air blowing heads 84, air flows in the connecting air pipe 82 under the action of the air pump 81, and then air flows out from the air blowing heads 84 under the action of the annular pipe 83.
[0023] A plurality of air blowing heads 84 are arranged in a ring on the surface of the annular tube 83, and all the air blowing heads 84 are facing the center line of the annular tube 83. In this embodiment, this arrangement improves the uniformity of air flow when the air blowing heads 84 are working, thereby improving the uniformity of air blowing on the cable.
[0024] The water return mechanism 10 includes a water storage tank 101 fixed to the surface of the support leg 6. The surface of the water storage tank 101 is connected to a plurality of heat dissipation pipes 102. The other end of the heat dissipation pipes 102 is connected to the inner cavity of the lower frame 4. A water pump 103 is connected to one side of the surface of the water storage tank 101. The other end of the working end of the water pump 103 is connected to a return water pipe 104. The other end of the return water pipe 104 is connected to the inner cavity of the upper frame 5. In this embodiment, through the arrangement of the water storage tank 101, heat dissipation pipes 102, water pump 103 and return water pipe 104, the water in the upper frame 5 flows into the lower frame 4 through the two side channels. Under the action of the heat dissipation pipes 102, the water enters the water storage tank 101. Then, under the action of the water pump 103, the water returns to the upper frame 5 through the return water pipe 104.
[0025] There are several heat dissipation pipes 102, which are arranged at equal intervals on the surface of the water storage tank 101.

[0027] Working principle: During use, the raw material supply body 1 provides molding raw material to the extrusion mechanism body 2. The cable is extruded and sheathed sequentially through the extrusion mechanism body 2 and the extrusion head 3. After the cable sheath is formed, it passes through the upper frame 5. Under the action of water in the upper frame 5, the cable sheath undergoes heat exchange treatment, improving the molding effect. After the cable sheath passes through the upper frame 5, the water on the surface of the cable is blown away by the air blowing mechanism 8, causing the water to fall into the air blowing frame 7. The water in the air blowing frame 7 can then flow into the lower frame 4. At this time, the water in the upper frame 5... Water can also flow into the lower frame 4. The water is filtered by the filter plate 9 and can enter the water storage tank 101 through the heat dissipation pipe 102. When the water passes through the heat dissipation pipe 102, since there are multiple heat dissipation pipes 102, the water can be cooled by the heat dissipation pipe 102, so as to avoid the water heat not being dissipated and returning to the upper frame 5, which would reduce the heat exchange effect. At this time, the staff can use the water pump 103 to make the water in the water storage tank 101 return to the upper frame 5 through the return water pipe 104 to complete the water circulation.
