Further, the diameter of the rotating ring is larger than the diameter of the circumscribed circle of the die.
Furthermore, the outside of mould is equipped with the strengthening rib, the strengthening rib distributes along the lateral wall length direction and the circumferencial direction of mould.
Further, the height of the reinforcing rib is smaller than that of the rotating ring.
Further, still include and rotate the seat, it is equipped with the rotation wheel to rotate the seat, it contacts with the rotating ring to rotate the wheel.
Further, the cross section of the fixing anchor is of a T-shaped structure.
Further, one end of the rotating shaft is connected with the centrifuge.
The invention has the beneficial effects that: the upper die and the lower die which are hinged with each other are fixed through the locking device, so that the bolt tightening in the traditional die processing is reduced, the time is saved, and the production efficiency is improved; due to the octagonal structure, the bending and breaking strength of the telegraph pole is higher, and the wind resisting and guiding effects are good; the arrangement of the anchor on the inner core increases the contact between the inner core and the cement layer and increases the connection strength between the inner core and the cement rod; the arrangement of the buffer layer prolongs the service life of the die and is convenient for demoulding; in the centrifugal rotation process, the stability of the die in the rotation process is ensured by matching the rotating wheel with the rotating ring.
