Insulators used in high-voltage or ultra-high-voltage power transmission lines were ceramic insulators at the earliest. Along with the emergence of composite insulator, compare porcelain insulator, composite insulator has following advantage: light weight, good explosion-proof performance and excellent electrical performance, and can especially reach very high pollution level. The inner supporting member of the composite insulator, i.e., the core of the composite insulator, is also receiving more and more attention in the industry. The composite insulator core is divided into a solid core and a hollow core, wherein the solid core is mainly used in a high-voltage overhead line and becomes a composite insulator for the line, and the hollow core is mainly used in an in-station insulator, such as a mutual inductor, a high-voltage switch, a circuit breaker and the like.

When the hollow insulator is formed, the composite insulator core has the problems that the bending strength, the impact strength and the thermal deformation temperature (Tg) fluctuate, and the composite insulator core is shortened after subsequent secondary heating and pressurization (such as an injection process) and the like, so that an iron rod needs to be placed in the insulator core during forming, and when the iron rod is used for an injection mold, the iron rod provides support for the composite insulator core, and the composite insulator core is prevented from being damaged due to stress spalling during forming. In the prior art, after the insulator is produced, the iron rod needs to be pulled out, and the iron rod and the insulator core generate certain adhesive force during injection molding, so that the iron rod is difficult to take down easily by hands.
