When supporting the tire blank, the first arc support plate is pushed first, and the second arc support plate is pushed later, and finally the first arc support plate and the second arc support plate are spliced ​​into a circle.

[0009] The first and second arc locking blocks are installed at one end of the third right-angled trapezoidal moving block away from the center column, and the second arc locking block is arranged on the side of the first arc locking block close to the center column. When supporting the tire blank, the first arc locking block is pushed first, and the second arc locking block is pushed later. Finally, the first arc locking block and the second arc locking block are spliced ​​into a circle.

[0017] No matter it is a tire with an aspect ratio of 35 series or even smaller, no matter it is a hard apex with a height of 15mm or a shorter and thicker hard apex, the head drum structure of the present invention can achieve normal molding, solving the problems of hollow bead and air bubbles that are common in the one-step production of high-end tires.

[0018] The key to solving the problem of poor turn-up is the addition of a pressurization step after the tire is locked. Traditional die-type die-type tyres cannot be pressurized after turn-up, and relying solely on the turn-up rod cannot solve the problem of bubbles between the layers of high-end tires, resulting in the inability to develop high-end tire specifications in one go.
