Problems solved by technology
[0002] When the traditional hollow composite insulator is injected with liquid glue, the uniformity of the injection is completely adjusted by the flow channel of the mold. Even if there are eight points of glue injection, it is difficult to ensure the balance of the amount of glue injected, which reduces the performance of the product and brings problems to production. Great inconvenience

Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the present invention will be further described:
[0014] Such as figure 1 As shown, the hollow composite insulator injection liquid glue flow distributor includes a flow equalizer and a hydraulic device. The flow equalizer is composed of a feed pipe 1, a flow equalization pipe 2 and a discharge nozzle 3, and the discharge nozzle 4 is 8. The feed pipe 1 and the discharge nozzle 3 are respectively welded with the flow equalization pipe 2. The diameter of the feed pipe 1 is 25-35mm, the diameter of the flow balance pipe 2 is 45-55mm, and the diameter of the discharge nozzle 3 is 8-12 mm, specifically, the diameter of the feed pipe 1 is 30 mm, the diameter of the flow equalization pipe 2 is 50 mm, and the diameter of the discharge nozzle 3 is 10 mm.
[0015] The method of using the liquid glue flow distributor for injection of hollow composite insulators. Before injection, the flow equalizer 2 is separated from the mold 4; d...

Abstract
The invention relates to a hollow composite insulator injection liquid glue flow allocator and a using method thereof. The invention is characterized in that the flow equalizer is composed of a feeding pipe, a flow equalizing pipe and discharging nozzles, the feeding pipe and the discharging nozzles are respectively welded and fit with the flow equalizing pipe; before injection, the flow equalizer and a mold are separated; during injection, a hydraulic device acts to push the flow equalizer to move towards the mold, and the discharging nozzles are closely propped against the arc-shaped grooveof the mold; the glue is injected into the flow equalizing pipe through the feeding pipe from the material pipe of a material pump, and ejected out of the discharging nozzles to be injected into the mold to be injected; after vulcanization for 15min, the hydraulic device acts partially to withdraw the flow equalizer. The flow equalizer leads the pressure of the glue to change from high to low based on the mutual cooperation of the feeding pipe, the flow equalizing pipe and the discharging nozzles with different diameters, and to be ejected out of the eight discharging nozzles after pressure equalizing in the flow equalizing pipe; the process of pressurizing and depressurizing of the glue is realized by the change of the diameters of the flow passage, thus achieving the aim of glue flow equalization.
Description
technical field [0001] The invention relates to a hollow composite insulator injection liquid glue flow distributor and a use method thereof. Background technique [0002] When the traditional hollow composite insulator is injected with liquid glue, the uniformity of the injection is completely adjusted by the flow channel of the mold. Even if there are eight points of glue injection, it is difficult to ensure the balance of the amount of glue injected, which reduces the performance of the product and brings problems to production. Very inconvenient. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical solution of a hollow composite insulator injecting liquid glue flow distributor and its usage method. [0004] The hollow composite insulator injection liquid glue flow distributor includes a flow equalizer and a hydraulic device, and is characterized in that the flow equalizer is ...
