[0026] Specifically, the inner rotation transport structure 100 includes an inner vertical transport tube 1 and an inner transverse transport tube 2, the inner input channel includes an inner vertical input channel 11 and an inner transverse input channel 21 that are interconnected, the inner output channel includes an inner vertical output channel 12 and an inner transverse output channel 22 that are interconnected, the inner vertical input channel 11 and the inner vertical output channel 12 are not interconnected and are arranged in the inner vertical transport tube 1, and the inner transverse input channel 21 and the inner transverse output channel 22 are not interconnected and are arranged in the inner transverse transport tube 2.

[0027] Specifically, the outer transverse transport pipe 4 is sleeved on the outer periphery of the outer vertical transport pipe 3, and an outer upper bearing 43 and an outer lower bearing 44 are provided between the outer vertical transport pipe 3 and the outer transverse transport pipe 4. The outer transverse transport pipe 4 rotates on the outer peripheral surface of the outer vertical transport pipe 3 under the action of the outer upper bearing 43 and the outer lower bearing 44.

[0028] Specifically, the inner vertical transport pipe 1 is arranged through the outer vertical transport pipe 3, the inner transverse transport pipe 2 is sleeved on the outer periphery of the inner vertical transport pipe 1 and is located above the outer transverse transport pipe 4, and an inner upper bearing 23 and an inner lower bearing 24 are provided between the inner vertical transport pipe 1 and the inner transverse transport pipe 2. The inner transverse transport pipe 2 rotates on the inner circumferential surface of the inner vertical transport pipe 1 under the action of the inner upper bearing 23 and the inner lower bearing 24.

This arrangement can effectively prevent the inner vertical transport pipe 1 and the outer vertical transport pipe 3 from being interfered with by the heat transfer from the high temperature to the low temperature due to the passage of media of different temperatures, and effectively ensure that the media will not interfere with each other when passing through the outer vertical transport pipe 3 and the inner vertical transport pipe, so as to ensure that the required temperature for transportation to the first injection module 61 and the required temperature for the second injection module 62 meet the requirements.

[0030] Specifically, the outer transverse transport pipe 4 is provided with three outer sealing ring grooves 45 and three outer sealing members 46. The three outer sealing ring grooves 45 are respectively arranged between the outer transverse input channel 41 and the outer transverse output channel 42 and on both sides. The three outer sealing members 46 are stuck in the three outer sealing ring grooves 45 to achieve mutual isolation between the outer transverse input channel 41 and the outer transverse output channel 42, thereby ensuring that the medium in the outer transverse input channel 41 and the medium in the outer transverse output channel 42 will not flow between each other, thereby effectively improving the sealing effect.

[0031] Specifically, the inner transverse transport pipe 2 is provided with three inner sealing ring grooves 25 and three inner sealing members 26.

The three inner sealing members 26 are stuck in the three inner sealing ring grooves 25 to achieve mutual isolation between the inner transverse input channel 21 and the inner transverse output channel 22, thereby ensuring that the medium in the inner transverse input channel 21 and the medium in the inner transverse output channel 22 will not flow between each other, thereby effectively improving the sealing effect.

[0032] Specifically, an inner stop plate 16 is provided above the inner transverse transport tube 2, and the inner stop plate 16 limits the inner transverse transport tube 2 to the outer peripheral surface of the inner vertical transport tube 1.

[0033] Specifically, an outer stop plate 33 is provided between the outer transverse transport tube 4 and the inner transverse transport tube 2. The outer stop plate 33 limits the outer transverse transport tube 4 to the outer peripheral surface of the outer vertical transport tube 3. When the outer transverse transport tube 4 rotates relative to the outer periphery of the outer vertical transport tube 3, it will not separate from the outer vertical transport tube 3.

[0035] Specifically, the outer transverse transport tube 4 is arranged on the outer periphery of the outer vertical transport tube 3 and is located above the rotating table 52. The outer transverse transport tube 4 rotates on the outer peripheral surface of the outer vertical transport tube 3 through the action of the outer upper bearing 43 and the outer lower bearing 44, so that the outer transverse transport tube 4 and the first injection mold 61 on the rotating table 52 can rotate synchronously.

The outer transverse input channel 41 and the outer transverse output channel 42 are annular. When the rotating table 52 and the outer transverse transport pipe 4 rotate relative to the outer vertical transport pipe 3, it is ensured that the medium with the required temperature can be continuously input to the first injection module 61, the required temperature for the first injection module 61 is maintained stable, and the demoulding quality is improved.

[0036] Specifically, the inner upper bearing 23 and the inner lower bearing 24 enable the inner transverse transport tube 2 to rotate on the outer circumferential surface of the inner vertical transport tube 1, so as to realize the synchronous rotation of the inner transverse transport tube 2 and the second injection module 62 on the rotating table 52. The inner transverse input channel 21 is connected to the input end of the second injection module 62, and the inner transverse output channel 22 is connected to the output end of the second injection module 62. The medium enters from the inner vertical input channel 11 and passes through the inner transverse input channel 21, the input end of the second injection module 62, the output end of the second injection module 62, and the inner transverse output channel 22 in sequence, and then is discharged from the inner vertical output channel 12. The inner transverse input channel 21 and the inner transverse output channel 22 are annular. When the inner transverse transport tube 2 rotates relative to the inner vertical transport tube 1, it is ensured that the medium of the required temperature can be continuously input to the second injection module 62, so as to maintain the stability of the required temperature provided to the second injection module 62 and improve the demolding quality.

[0037] In summary, the utility model forms an inner passage by setting an inner input channel, a second injection module 62 and an inner output channel, and forms an outer passage by an outer input channel, a first injection module 61 and an outer output channel.
