[0040] ​Specifically, the heating assembly includes a plurality of heating rods 10, which are used to release heat uniformly when the production process is started and the temperature of the mold 11 needs to be raised to promote the melting and molding of the raw material, so as to heat the internal space of the heating cylinder 9, and the heat is transmitted to the mold 11 through the heating cylinder 9. The spring 14 is used to provide elastic support for the baffle 15 in the normal state, ensure that the plug-in block 16 is stably plugged into the T-shaped block 12, and realize the locking of the mold 11. The plug-in block 16 is plugged into the T-shaped block 12 on the outside and is slidingly connected to the inside of the fixed disc 13, which is used to cooperate with the baffle 15 to complete the locking and unlocking operations of the mold 11. When locked, the relative fixation of the mold 11 and the heating cylinder 9 is ensured, and when unlocked, it can be smoothly removed. The pull rope 17 is used to overcome the elastic force of the spring 14 when the rotating handle 19 drives the winding wheel 18 to rotate, so as to pull the baffle 15 and the plug-in block 16 out of the T-shaped block 12 slowly, thereby unlocking the mold 11. The handle 19 is used to facilitate the operator to hold and rotate, thereby driving the winding wheel 18 to rotate and achieving the unlocking of the mold 11. The circulating pipe 4 is used to make the water in the circulating water tank 5 flow rapidly along the circulating pipe 4 under the driving of the pump, and cooperate with the heat-absorbing plate 7 and the heat dissipation fin 8 to complete the cooling operation in the mold 11

[0041] Working principle: when in use, the two extruder discharge pipes 20 connected to the outside of the fixed disc 13 accurately convey the polypropylene raw material produced by the extruder into the mold 11. When the production process is started, according to the processing characteristics of the polypropylene raw material, if the temperature of the mold 11 needs to be raised to promote the melting and molding of the raw material, at this time, the plurality of heating rods 10 uniformly distributed in the heating cylinder 9 release heat, uniformly heat the internal space of the heating cylinder 9, and the heat is transmitted to the mold 11 through the heating cylinder 9, creating a suitable high-temperature environment for the mold 11. The polypropylene raw material entering the mold 11 from the extruder discharge pipe 20 begins to gradually change from a solid state to a liquid state, and then is molded according to the shape of the mold cavity of the mold 11, gradually transforming into the shape of a cable protection tube;

[0042] In the production process, when the pipe material is molded in the mold 11, it needs to be quickly cooled and shaped. At this time, the circulating pump 6 drives the water in the circulating water tank 5 to flow rapidly along the circulating pipe 4 under the strong power of the pump, absorbs the heat generated by the mold 11, and at the same time, the heat-absorbing plate 7 outside the circulating water tank 5 quickly absorbs the heat in the circulating water, and then the heat is dissipated to the surrounding environment through the heat dissipation fin 8, realizing the rapid and uniform cooling and shaping of the pipe material, rapidly dissipating heat, and maintaining the efficient operation of the production line;

[0043] When the mold 11 needs to be replaced, the operator holds the handle 19 inside the fixed disc 13 by sliding connection, rotates the handle 19, drives the winding wheel 18 connected therewith to rotate, since the plurality of pull ropes 17 are fixedly connected outside the winding wheel 18 at the end away from the baffle 15, with the rotation of the winding wheel 18, the pull ropes 17 are gradually wound, the baffle pulls the compression spring and the plug-in block to slowly move out of the T-shaped block, the locking on the mold 11 is released, at this time, the mold 11 is slidingly connected with the heating cylinder 9, can be easily pulled out from the heating cylinder 9, after the old mold 11 is disassembled, the new mold 11 is embedded with the heating cylinder 9 through the T-shaped block 12 according to the same steps, and is locked again by using the fixed assembly, so that a new round of production can be quickly started, the mold is conveniently and quickly replaced, the mold replacement time is greatly shortened, and the production efficiency is improved.

[0044] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
