[0030] Furthermore, the injection molding heating device 2 also includes: a heating tube 24, which is evenly distributed in a spiral around the outer wall of the injection molding heating shell 21. The heating tube 24 is evenly distributed in a spiral around the lower half of the outer wall of the injection molding heating shell 21, and is used to conduct heat energy and melt the injection molding material in the injection molding heating shell 21. In addition, the inner wall of the injection molding heating shell 21 is also provided with a temperature sensing probe, which is used to monitor the temperature in the injection molding heating cavity, and transmit the monitoring data to the central controller through a sensor.

The exhaust hole 55 is mainly used to discharge the gas generated during injection molding. Before injection molding, the quick curing agent is injected into the packaging cavity through the exhaust hole 55, so that the melted injection molding material is quickly solidified and coated on the periphery of the optical cable to be repaired. The tearable sealing rubber ring 57 is set at both ends of the first mold 51 and the second mold 52 after being enclosed to prevent the melted injection molding material from overflowing and play a sealing role. In addition, the first mold 51 and the second mold 52 are both made of transparent materials, which makes it easy to observe the state of the internal injection molding material during the production process and stop packaging at any time to take out the optical cable to be repaired.

[0037] In addition, the present embodiment further includes a power switch device 9, which includes a transformer, an input module, an output module and a control switch, wherein the transformer ensures the power demand of the input module and the output module and plays a role of safety isolation. The input voltage of the input module is 220V, and the output module consists of 1 AC 220V and 2 DC 24V. 1 AC 220V output module provides power for the heating tube 24, and 3 DC 24V output modules provide power for the display screen 8, the central controller, the first electric cylinder 6 and the second electric cylinder 7. The control switches include four, namely, a main switch, an injection heating switch, a docking switch and a packaging switch. The main switch controls the total circuit of all power supplies. When turned on, it supplies power to the display screen 8 and the central controller at the same time. The injection heating switch controls the heating of the heating tube 24 on the outer wall of the injection heating shell 21 and monitors the temperature of the injection heating cavity in the injection heating shell 21. The docking switch controls the docking of the first injection port 23 at the bottom of the injection heating shell 21 with the second injection port 56 of the packaging device 5.

At the same time, the outer sheath of the damaged cable to be repaired is polished and cleaned with alcohol. The treated cable to be repaired is placed in the packaging cavity formed by the first mold 51 and the second mold 52. The two ends of the first mold 51 and the second mold 52 are sealed with a tearable sealing rubber ring 57. The first mold 51 and the second mold 52 are sealed and locked with a quick fixing buckle 54 to prevent the melted liquid injection material from overflowing. After sealing, the packaging device 5 is placed together with the cable to be repaired on the fixed bracket 14 of the fixed base 11, and the recessed parts of the four corners of the bottom of the second mold 52 are stuck into the four corners of the fixed bracket 14, so that the second injection port 56 at the top of the first mold 51 corresponds to the first injection port 23 at the lower end of the injection heating shell 21. The second electric cylinder 7 pushes the whole injection molding heating device 2 downward, so that the second injection molding port 56 protruding outward from the packaging device 5 pushes into the first injection molding port 23 at the lower end of the injection molding heating shell 21. After the two are sealed and connected, the check valve 22 of the first injection molding port 23 at the lower end of the injection molding heating shell 21 is opened, so that the fluid injection molding material in the injection molding heating shell 21 can flow into the packaging cavity. Before injection molding, the fast curing agent is injected into the injection molding cavity through the exhaust hole 55 on the first mold 51, and then the first electric cylinder 6 drives the moving end of the piston 3 to push the melted injection molding material inside the injection molding heating shell 21, so that the melted injection molding material is completely filled into the packaging cavity and mixed with the fast curing agent, so that it is quickly cured, and the repair work of the damaged optical cable is completed.
