[0026] Furthermore, the injection tubes 6 are interconnected through the delivery tube 7, which has an "I" shaped structure and can transport the injection molding material between the fixed mold 1 and the moving mold 5 to perform injection molding on the insulating plastic cover.

[0027] A spring 10 is connected to the side of the moving mold 5, a moving rod 11 is connected to the end of the spring 10, and a demolding ring 9 is connected to the end of the moving rod 11.

[0028] Furthermore, the demolding ring 9 is slidably connected to the moving mold 5. The demolding ring 9 has a circular structure, which can avoid affecting the closing of the moving mold 5 and the fixed mold 1 to make the insulating plastic cover. At the same time, the demolding ring 9 can be assembled and moved later to assist in demolding.

[0029] Furthermore, the moving rod 11 has a "+" shaped structure. The moving rod 11 forms an elastic structure with the moving mold 5 through the spring 10. The position of the moving rod 11 corresponds to the position of the baffle 15, so that the moving rod 11 can move flexibly, thereby driving the demolding ring 9 to move flexibly. When the moving mold 5 moves away from the fixed mold 1, the baffle 15 can press the moving rod 11, thereby controlling the demolding ring 9 to move and realize demolding.

[0030] The moving mold 5 is equipped with a heat-conducting pillar 12 and a cooling pipe 16. The upper end of the cooling pipe 16 is connected to a water inlet pipe 13, and the lower end of the cooling pipe 16 is connected to a water outlet pipe 14. A baffle 15 is installed on the side of the mounting plate 3.

[0031] Furthermore, the heat-conducting pillars 12 are evenly distributed inside the moving mold 5. The heat-conducting pillars 12 are in contact with the cooling pipes 16, and the heat can be conducted by the heat-conducting pillars 12, so that the heat can be exchanged with the cooling pipes 16 to cool down the insulating plastic cover.

[0032] Further, the cooling pipe 16 is in "S" shape structure, and a gap exists between the cooling pipe 16 and the moving rod 11, so that the flow time of the cold water in the cooling pipe 16 is prolonged, the injection mold is cooled, and the moving rod 11 is prevented from being blocked;

[0033] Specifically, when the injection mold is used, the hydraulic rod 4 is opened, the movable mold 5 is pushed to move towards the fixed mold 1, at this time, the baffle 15 and the moving rod 11 are away from each other, the compressed spring 10 controls the moving rod 11 to reset and move, so that the demolding ring 9 resets and moves, the demolding ring 9 is retracted into the movable mold 5, the movable mold 5 and the fixed mold 1 are closed, the injection material is injected through the connecting nozzle 8, enters the inner cavity of the fixed mold 1 along the conveying pipe 7 and the injection pipe 6, the movable mold 5 and the fixed mold 1 are used to realize the compression molding of the insulating plastic cover, the water inlet pipe 13 is connected with the cold water source outside, the cold water enters the cooling pipe 16 along the water inlet pipe 13, and finally is discharged from the water outlet pipe 14, so as to realize the circulation flow of the cold water in the cooling pipe 16, the heat conduction column 12 can concentrate and conduct heat, one end of the heat conduction column 12 is in contact with the cooling pipe 16, the cold water in the cooling pipe 16 can be used to cool the heat conduction column 12, so as to realize rapid heat exchange and rapid cooling of the insulating plastic cover, so that the insulating plastic cover can be quickly formed and solidified.

[0034] After the insulating plastic cover is injection molded, the hydraulic rod 4 drives the movable mold 5 to move away from the fixed mold 1, at this time, the molded insulating plastic cover is attached to the movable mold 5 and moves with the movable mold 5, after the movable mold 5 and the fixed mold 1 are away from each other, the moving rod 11 is in contact with the baffle 15, the moving rod 11 is blocked by the baffle 15, the moving rod 11 is compressed to compress the spring 10, and the demolding ring 9 is pushed to move, the demolding ring 9 pushes the molded insulating plastic cover to demold, and the contents not described in detail in the specification belong to the prior art known to those skilled in the art.
