When the thermoplastic fluid conveying pipeline is used, the mounting plate is provided with a material port which is used for molten plastic to pass through and is communicated with the first direct current channel, the spherical end of the pipeline main body can rotate in the spherical groove of the pipeline seat at a small angle through the structure, and meanwhile, the molten plastic extruded after rotation can still flow in the first direct current channel and the second direct current channel, so that the thermoplastic fluid conveying pipeline can still perform small amount of angular deflection or displacement after connection.

In the above thermoplastic fluid conveying pipe, a first rotating gap is formed between the spherical end head and the spherical groove, and a second rotating gap is formed between the pipe main body and the notch edge of the spherical groove. After the pipeline main body and the pipeline seat are installed through the first rotating gap and the second rotating gap, a rotating space is formed between the spherical end and the spherical groove, and therefore the spherical end of the pipeline main body can better rotate in the spherical groove of the pipeline seat in a small angle.

In one of the above thermoplastic fluid conveying pipes, the first rotational gap is equal to or greater than 0.08mm and equal to or less than 0.15mm. The first rotating gap is too small, so that the spherical end can not rotate in the spherical groove, and the first rotating gap is too large, so that the molten plastics in the first direct flow channel and the second direct flow channel overflow to the first rotating gap to cause leakage, and the first rotating gap between the first rotating gap and the second rotating gap can meet the rotation of the spherical end and can avoid the leakage phenomenon.

In the above thermoplastic fluid conveying pipe, the pipe seat includes a front pipe seat and a rear pipe seat, the front pipe seat and the rear pipe seat are detachably connected by a plurality of bolts, the spherical groove portion is located on the front pipe seat, and part of the spherical groove portion is located on the rear pipe seat. The structure is convenient for the disassembly and the assembly of the spherical end head of the pipeline main body and the pipeline seat.

In the above thermoplastic fluid conveying pipeline, the pipeline main body is detachably connected with an extension pipeline, and a third direct current channel communicated with the second direct current channel penetrates through the extension pipeline. Above-mentioned structure is convenient for extend pipeline and pipeline main part's dismouting, can improve pipeline main part's commonality through changing extend pipeline simultaneously for pipeline main part can match different moulds.

In the above thermoplastic fluid conveying pipe, the first straight flow channel, the second straight flow channel and the third straight flow channel have the same width. The structure ensures that the amount of the molten plastics in the first direct flow channel, the second direct flow channel and the third direct flow channel is consistent, so that the heater can better heat the molten plastics in the flow channels.

Compared with the prior art, the thermoplastic fluid conveying pipeline has the advantages that: this thermoplastic fluid pipeline's pipeline main part's spherical end can carry out the rotation of small angle in the spherical recess of pipeline seat, and simultaneously, the molten plastics of extruding after rotating still can flow in direct current way one, direct current way two and direct current way three to make this thermoplastic fluid pipeline still can carry out a small amount of angle deflection or displacement after connecting.
