The cleaning shaft 610 and the first lower mold shell 310 can be rotatably assembled in a circular manner and cannot be axially moved. A second clutch sleeve 520 is installed on the end of the cleaning shaft 610 close to the first clutch sleeve 510. A second clutch protrusion 521 is provided on the second clutch sleeve 520. The second clutch protrusion 521 is engaged with the first clutch protrusion 511 so that the second clutch sleeve 520 and the first clutch sleeve 510 cannot rotate relative to each other in a circular manner. At this time, the rotating motor 230 can drive the cleaning shaft 610 to rotate.

[0045] The cleaning shaft 610 is provided with a rotating wheel sleeve 351, on which a rotating wheel 350 is mounted, and the outer wall of the rotating wheel 350 is pressed against the outer wall of the metal suction tube 900, so that when the cleaning shaft 610 rotates, the rotating wheel 350 can be driven to rotate, and the rotating wheel 350 drives the metal suction tube 900 to rotate around its own axis, so that the inner brush 440 and the lower mold outer brush 340 brush the inner and outer walls of the metal suction tube 900. Rotating the metal suction tube 900 at the flushing station and the drying station can also increase the drying effect and efficiency.

[0046] See also Fig. 9 , Figure 11-13 The locking assembly includes a locking housing 370 mounted on the lower mold frame 312, a locking wheel 530 sleeved outside the shaft sleeve 620, a locking block 550, and a cable 540. The outer wall of the locking wheel 530 is provided with a locking groove 531 corresponding to the pipe groove 332, and one of the locking grooves 531 is engaged with the locking block 550 so that the shaft sleeve 620 (the second lower mold shell 320) cannot rotate. The locking block 550 is assembled with one end of the locking block shaft 640, and the other end of the locking block shaft 640 is fitted with a spring 710 that passes through the partition 373 and is assembled with the wedge block 820. The locking block shaft 640 and the partition 373 can slide axially and cannot rotate relative to the circumference. The partition 373 is mounted on the locking housing 370, and the spring 710 applies an elastic force to the locking block 550 to press the locking groove 531 so that the locking block 550 and the locking groove 531 remain engaged.

[0047] The wedge block 820 is provided with a first inclined surface 821, which is in contact with and slidably assembled with the second inclined surface 811. The second inclined surface 811 is provided on the switch block 810. The switch block 810 is provided with a switch block groove 812 which is sleeved on the outside of the lock block shaft 640. The switch block 810 is also assembled with one end of the tension spring 720 and one end of the pull shaft 630. The other end of the tension spring 720 is assembled and fixed with the spring shaft 372. The spring shaft 372 is installed on the lock housing 370. The lock housing 370 is also provided with an axial hole 371. The other end of the pull shaft 630 is inserted into the axial hole 371 and engaged with it, and can be axially slidably assembled.

[0048] The pull shaft 630 is assembled with one end of the cable 540, and the other end of the cable 540 passes through the shaft hole 371 and is assembled with the stop block 541 and the pull ring 542 in sequence; the lower mold frame 312 is also provided with a stop groove 313, and the stop block 541 cannot pass through the stop groove 313. When the second lower mold frame 320 needs to be rotated, the cable 540 is pulled through the pull ring 542 to drive the pull shaft 630 and the switch block 810 to move toward the shaft hole 371 to overcome the elastic force of the tension spring 720 until it is pulled in place, and then the cable 540 is bent toward the stop groove 313, so that the stop block 541 is located below the stop groove 313, the cable 540 is inserted into the stop groove 313 and the stop block 541 is located below the stop groove 313, and the cable 540 is released, and the tension spring 720 applies tension to the cable through elastic force, but the cable cannot move due to the limit of the stop block 541. During this process, the switch block 810 cooperates with the first inclined surface 821 through the second inclined surface 811 to drive the wedge block 820 and the lock block shaft 640 to overcome the elastic force of the spring 710 and drive the lock block 550 to move toward the partition 371, until the lock block 550 completely exits the lock groove 531 and does not affect the rotation of the locking wheel 530. At this time, the second lower mold shell 320 can be rotated to clamp the metal suction tube 900 at the lower mold outer brush 340 at different positions. After the metal suction tube 900 is clamped, the cable is taken out from the stop groove 313, the tension spring 720 drives the switch block 810 to reset, and the spring drives the lock block to reset to lock the second lower mold shell 320 again. This design structure is relatively simple, and can maintain the locked and unlocked states, and is also relatively convenient to use.
