By additionally arranging the synchronization unit, the synchronous movement of the support frame and the injection lower die can be realized, and the phenomenon of successive actions is effectively avoided.
The composite insulator drying and injecting system has other defects during processing: when silica gel is injected to the surface of the core rod to form the umbrella skirt, the silica gel is required to be heated and melted to form liquid, and then the liquid is injected into a mold cavity to form the umbrella skirt, so that in the process, the temperature of the formed umbrella skirt is higher, the silica gel has certain viscosity, the umbrella skirt can be bonded with the upper mold or the lower mold cavity under the condition, the demolding cannot be performed smoothly, the demolding is required to be matched by workers, the temperature of the umbrella skirt is higher, the workers cannot directly perform demolding by hands, other protection measures are required to be matched, and otherwise, the workers are easily scalded, and great troubles are caused.
