Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric pole manufacturing, and particularly relates to an efficient electric pole manufacturing die. BACKGROUND

[0002] In modern power infrastructure construction, as a key component for supporting power transmission lines, the quality and production efficiency of electric poles are very important. At present, with the continuous growth of power demand, the demand for electric poles is also increasing. Electric poles are usually made of electric pole manufacturing dies.

[0003] In the production process of the existing electric pole manufacturing die, cement slurry is injected into the die, and after the cement slurry in the die solidifies, the electric pole is pushed out of the die by a push rod. However, due to the large friction between the electric pole and the die, the surface of the die will inevitably be worn and scratched after long-term use, resulting in a rough surface and an increased friction coefficient between the electric pole and the die. At the same time, the concrete will have a strong adhesion to the surface of the die during the solidification process. In these cases, it becomes extremely difficult to push the electric pole out of the die by relying solely on the push rod, and the demolding time is greatly extended, which seriously affects the production efficiency. Moreover, when the push force of the push rod is uneven due to the adhesion generated during the demolding process, the electric pole will locally bear excessive pressure, which can easily cause cracks, chunks, and other defects, thereby increasing the scrap rate. SUMMARY
