[0002] In ultra-high voltage power systems, insulators play a crucial role. They not only support high-voltage power lines but also ensure sufficient insulation between power lines and between power lines and towers. Traditional insulators are typically made of insulating materials such as ceramics or glass. While these materials have good insulation properties, they have certain tolerances in shape and size. This can lead to poor compatibility with molds during manufacturing, thus affecting the quality and production efficiency of the insulators.
[0003] In ultra-high voltage environments, insulators need to withstand extremely high voltages and mechanical stresses, which requires them to possess extremely high mechanical strength and electrical insulation properties. Furthermore, the manufacturing process of insulators requires precise control to ensure consistency in their shape and dimensions, thereby meeting the requirements of high-voltage power systems.
[0004] However, existing insulator mold structures have some problems during production, such as inconsistent insulator heights leading to incompatibility with the mold and a tendency for insulators to crack or break. These problems not only affect the molding quality of the insulators but may also result in low production efficiency and material waste. Utility Model Content

[0040] Furthermore, the ultra-high voltage insulator mold structure also includes a height equalizing screw 4; one end of the height equalizing screw (4) passes through the middle positioning part 5, the buffer component 2, and the rear mold insert in sequence.
