[0005] In the above technical solution, the connecting frame includes a first connecting plate and a second connecting plate connected by a connecting rod, and the first connecting plate is mounted on the output shaft of the first cylinder.

[0006] In the above technical solution, the output shaft of the second cylinder passes through the second connecting plate and is connected to the inner mold shaft.

[0007] In the above technical solution, the output shaft of the first cylinder is fixedly connected to the first connecting plate of the connecting frame, and the second connecting plate of the connecting frame is fixedly connected to the outer mold shaft.

[0008] In the above technical solution, the inner mold shaft of the inner mold is arranged inside the outer mold shaft of the outer mold.

[0009] In the above technical solution, a connecting frame seat is provided on the bracket, and the connecting rod of the connecting frame is installed on the connecting frame seat and can move relative to the connecting frame seat.

[0010] In the above technical solution, the bracket is provided with an outer mold base, and the outer mold is arranged in the center hole of the outer mold base.

[0011] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the present invention arranges a first cylinder and a first cylinder on the bracket, and the first cylinder drives the outer mold to move through the connecting frame, and the second cylinder directly drives the inner mold to move. The first cylinder and the first cylinder operate independently, so that the forward and backward movement of the inner mold and the outer mold can be controlled separately to achieve the work position required for folding. The structure is simple and compact, and it is easy to use on the folding machine. BRIEF DESCRIPTION OF THE DRAWINGS
