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 groove of 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.

Embodiment
Below in conjunction with Figure of description the present invention is further specified:
As shown in Figure 1, hollow composite insulator injection liquid glue flow allocator comprises flow equalizer and hydraulic means; Flow equalizer is made up of feed pipe 1, flow equalization pipe 2 and discharging mouth 3, and wherein discharging mouth 4 is 8, and feed pipe 1 cooperates with 2 welding of flow equalization pipe respectively with discharging mouth 3; The caliber of feed pipe 1 is 25-35mm, and the caliber of flow equalization pipe 2 is 45-55mm, and the caliber of discharging mouth 3 is 8-12mm; Particularly; The caliber of feed pipe 1 is 30mm, and the caliber of flow equalization pipe 2 is 50mm, and the caliber of discharging mouth 3 is 10mm.
The method for using of hollow composite insulator injection liquid glue flow allocator, before the injection, flow equalizer 2 separates with mould 4; During injection, hydraulic means action promotes flow equalizer 2 and moves to mould, and discharging mouth 3 holds out against mould 4 circular grooves, is tightly connected; The caliber of supposing feed pipe 1 is 30mm, the long-pending S that uses of tube section
1Expression, the caliber of flow equalization pipe 2 is 50mm, the long-pending S that uses of tube section
2Expression, the caliber of discharging mouth 3 is 10mm, the long-pending S that uses of tube section
3Expression is when sizing material pressure is P
1During=200bar, by formula P
1S
1=P
2S
2Learn that sizing material pressure and cross section of fluid channel are long-pending to be inversely proportional to, when flow diameter became big, sizing material pressure diminished, and sizing material carries out step-down in flow equalization pipe 2 all presses, at this moment sizing material pressure
After sizing material is all pressed in flow equalization pipe 2, penetrated by 8 discharging mouths 3, this moment, flow diameter diminished again, and it is big that sizing material pressure becomes, this moment pressure
Inject mould 4 to be injected; After vulcanizing 15 minutes, flow equalizer 2 is return in the hydraulic part action.Through the variation of flow diameter, make sizing material realize the process of boosting after the first step-down, reach the purpose of sizing material flow equalization.
The application of hollow composite insulator injection liquid glue flow allocator in hollow combined insulator product injection technique: carry out surface treatment with to be injected, send into injection molding, Mould locking machine moves mold-locked, and clamp force is about 1500T; Material pump mixes A, the two component glue meterings of B, under 200bar pressure, liquid glue is injected mould through flow distributor, and the mould temperature is 90 ℃ during injecting glue, and liquid glue is full of mold cavity, about 120 ℃, is cured moulding.
Above-mentioned hollow composite insulator injection liquid glue flow allocator and method for using thereof; Flow distributor cooperatively interacts through feed pipe 1, flow equalization pipe 2 and the discharging mouth 3 of different tube diameters, and the pressure that makes material glue is from diminishing greatly, after in flow equalization pipe 2, all pressing; Penetrate from eight discharging mouths 3; Through the variation of flow diameter, make sizing material realize the process of boosting after the first step-down, reach the balanced purpose of material solation amount.
