Background
Utility poles are poles for electrical wiring and are one of the important infrastructures. Early utility poles were started from wooden poles, and later, due to the development of steel and reinforced concrete, and technical requirements, these two materials gradually replaced most of the wooden poles.
The utility pole is set up, has both avoided the more cable fault problem that the earthquake brought, need not excavate the underground and carry out the troubleshooting, and the wire pole can resist wind and snow in addition, and when flood or mud-rock flow take place, it suffers destruction to hardly distinguish which part of the cable system of the ground bottom, has increased the required time of salvageing electric power and has salvageed the cost. The utility pole may also serve as a geographical identifier.
The existing pouring mould rotates at a certain speed through a centrifugal machine, so that cement is attached to the periphery of a mould cavity, the telegraph pole is of a hollow structure, and then the mould is placed in a steamer, so that cement solidification is accelerated, and the telegraph pole is formed. And the wire pole of cylindrical structure is at centrifugal process, and a suture appears easily in the gap department of the amalgamation of cope match-die and lower mould, just can use after needing to handle the suture, and the steel reinforcement cage bone of placing in the mould in addition, the cladding of cement is not enough under the centrifugal action, appears the pine easily and takes off.

a casting mold for producing a cement telegraph pole comprises a mold, wherein the mold is formed by splicing an upper mold and a lower mold, an inner cavity formed after the upper mold is in butt joint with the lower mold is matched with the shape of the telegraph pole, the cross section of the mold is of an octagonal structure, the upper mold is rotatably connected with the lower mold, one end of the upper mold is hinged with the lower mold, a locking device fixed with the lower mold is arranged at the other end of the upper mold, an inner core is arranged in the mold, a fixing groove of the inner core is formed in the mold, the inner core is of a net-shaped structure of a reinforcement cage, a fixing anchor is arranged on the inner core in the circumferential direction and is arranged on the outer side of the inner core, a buffer layer is arranged on the inner sides of the upper mold and the lower mold, a rotating shaft is arranged at one end of the mold, rotating rings are arranged, and a hoisting ring is arranged on the upper die.
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.
