Abstract
The invention discloses a rubber injection mold of an insulator. The rubber injection mold comprises a mold frame, a runner plate and inserts, wherein the inserts form umbrella pages; the runner plate and the inserts are installed on the mold frame; rubber filling channels are arranged on the runner plate; rubber filling holes are formed in the rubber filling channels; both sides of the rubber filling holes are arranged opposite to each other; the rubber filling holes correspond to fourteen one-level rubber filling channels; the inserts correspond to the rubber filling channels; air discharge slots are formed in the inserts; and double-side rubber filling is adopted. The rubber injection mold is high in rubber filling speed, good in air discharge effect, short in molding time, high in production efficiency, low in power consumption and the like. The injection time is only about 3 minutes, because the injection time is short, injection can be directly carried out at the vulcanization temperature of about 160 DEG C, the injection time and the cooling time can be saved, the energy consumption is about 50KW per injection, and the efficiency can be improved by more than 40%.
Description
Technical field
The present invention relates to a kind of mould of industrial production, particularly a kind of rubber injection mold of insulator.
Background technology
In the prior art, produce the structure of the rubber injection mold of high voltage power transmission and transforming hollow insulator as shown in Figure 1, it comprises framed 1, runner plate 2 and forms the mold insert 3 of umbrella page, runner plate 2 and mold insert 3 are arranged on framed 1, runner plate 2 there is gum intaking passage, gum intaking passage has glue-feeder 4, the mold insert 3 of the corresponding multiple formation umbrella page of each gum intaking passage, mold insert 3 there is air discharge duct 31, whole mould only has four or eight enter glue point.The quantity of rubber injection mold due to injection point of this structure and the restriction of position, can only inject at about 120 DEG C, inject time was at about 30 minutes, untired gas in mould can be ensured like this, and then the curing temperature that temperature is elevated to 160 DEG C is carried out sulfuration, temperature-rise period needs about 30 minutes, power consumption 50KW, production also will wait mold temperature to be reduced to about 120 DEG C again and inject next time again after completing a product, 1.5 hours consuming time again, not only inefficiency, and power consumption is very large.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming prior art, and a kind of rubber injection mold is provided, to solve inefficiency that existing rubber injection mold causes because of the quantity of injection point and the restriction of position and the large problem of power consumption.
Technical scheme of the present invention is: a kind of rubber injection mold of insulator, it comprises the mold insert of framed, runner plate and formation umbrella page, runner plate and mold insert be arranged on framed on, runner plate there is gum intaking passage, gum intaking passage there is glue-feeder, mold insert has air discharge duct, it is characterized in that described gum intaking passage is one-level gum intaking passage, each mold insert has a gum intaking passage to correspond.
The further technical scheme of the present invention is: the corresponding plural gum intaking passage of described glue-feeder.
The present invention further technical scheme is: the glue-feeder two sides on described runner plate is oppositely arranged.
The present invention further technical scheme is: adopt bilateral enter glue.
The present invention enters glue owing to adopting each umbrella page in both sides, sizing material enters fast from both sides, the structural design of another both sides exhaust, fast sizing material can be full of mould, each umbrella page enters glue, have and enough enter glue point, glue can be entered fast, and then can directly directly inject at curing temperature, compared with prior art, have into glue speed fast, good exhaust effect, molding time is short, production efficiency is high, the feature such as low in energy consumption, only have about 3 minutes inject time, because inject time is very short, just can directly directly inject under the curing temperature of about 160 DEG C, inject time and temperature fall time can be saved, about energy consumption 50KW is saved in per injection, raise the efficiency more than 40%.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing rubber injection mold;
Fig. 2 is the structural representation of rubber injection mold of the present invention.
Detailed description of the invention
Below in conjunction with figure and detailed description of the invention, detailed construction of the present invention is further described.
As shown in Figure 2, rubber injection mold of the present invention comprises framed 1, runner plate 2 and forms the mold insert 3 of umbrella page, runner plate 2 and mold insert 3 are arranged on framed 1, runner plate 2 there is gum intaking passage, gum intaking passage is provided with glue-feeder 4, and every two of glue-feeder 4 is oppositely arranged face-to-face, corresponding 14 the one-level gum intaking passages of each glue-feeder 4, the mold insert 3 of the corresponding formation umbrella page of each one-level gum intaking passage, mold insert 3 has air discharge duct 31.
Operation principle of the present invention and using method are: sizing material passes through the nozzle injection of rubber injection machine to mould both sides die joint, by runner plate 2, step by step sizing material is expelled on each umbrella page, sizing material directly can carry out fast injection from the both sides of mould at the curing temperature of 160 DEG C and enter, sizing material is filled rapidly from the both sides of each umbrella page in mould, and the gas in mold insert 3 is discharged from the air discharge duct 31 of each umbrella page fast.
More than show and describe general principle of the present invention and principal character; the technical staff of the industry should understand; above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
