The second drive component 44 drives the third sub-mold 421 and the fourth sub-mold 422 to move toward each other to close the second mold 42, and define a second cavity between the third forming part 4211 and the fourth forming part 4221, and the annular film is located in the second cavity, thereby achieving the technical effect of the annular film extending into and being located in the second cavity.

[0054] The second driving assembly 44 includes a fifth driving member 441 and a sixth driving member 442. The fifth driving member 441 is connected and cooperated with the third sub-mold 421, and the fifth driving member 441 is used to drive the third sub-mold 421 to move closer to or away from the fourth sub-mold 422. The sixth driving member 442 is connected and cooperated with the fourth sub-mold 422, and the sixth driving member 442 is used to drive the fourth sub-mold 422 to move closer to or away from the third sub-mold 421.

[0055] When the second drive drives the third sub-mold 421 and the fourth sub-mold 422 to move in opposite directions to open the second mold 42 , the fifth drive member 441 drives the third sub-mold 421 to move away from the fourth sub-mold 422 , and the sixth drive member 442 drives the fourth sub-mold 422 to move away from the third sub-mold 421 .
