Abstract
The utility model provides a rubber injection mould which comprises a mould frame 1, a runner plate 2 and an inlaying piece 3 for forming an umbrella blade. The runner plate 2 and the inlaying piece 3 are arranged on the mould frame 1, rubber inlet channels are arranged on the runner plate 2, and rubber inlets 4 are arranged on the rubber inlet channels; each rubber inlet 4 is corresponding to two one-stage rubber inlet channels 5, each one-stage rubber inlet channel 5 is corresponding to two two-stage rubber inlet channels 6, each two-stage rubber inlet channel 6 is corresponding to two three-stage rubber inlet channels 7, each three-stage rubber inlet channel 7 is corresponding to two four-stage rubber inlet channels 8, and each four-stage rubber inlet channel 8 is corresponding to one inlaying piece 3 for forming the umbrella blade. A lower support 9 and a side support 10 are arranged on the mould frame 1, and an air exhaust groove 31 is arranged on the inlaying piece 3. The rubber injection mould has the characteristics of high rubber inlet speed, good air exhaust effect, short forming time, high production efficiency, low power consumption and the like. The injection only needs 3 minutes or so; as the injection time is short, the rubber injection mould can directly carry out injection under the vulcanization temperature of 160 DEG C or so, so as to save the injection time and the temperature drop time, save about 50KW of the energy consumption, and increase the efficiency by 50%.
Description
Technical field
The utility model relates to the mould that a kind of industrial production is used, particularly a kind of rubber injection mold that is used to produce the high voltage power transmission and transforming hollow insulator.
Background technology
In the prior art, the structure of the rubber injection mold of production 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 or leaf, runner plate 2 and mold insert 3 are installed on framed 1, on the runner plate 2 gum intaking passage is arranged, glue-feeder 4 is arranged on the gum intaking passage, the mold insert 3 of the corresponding a plurality of formation umbrella pages or leaves of each gum intaking passage, air discharge duct 31 is arranged on the mold insert 3, have only four or eight to advance the glue point on the entire die.The rubber injection mold of this structure is because the quantity of injection point and the restriction of position, can only about 120 ℃, inject, inject time is about 30 minutes, can guarantee not to be stranded in the mould gas like this, and then temperature is elevated to 160 ℃ curing temperature vulcanizes, temperature-rise period needs about 30 minutes, power consumption 50KW, production is finished and also will be waited mold temperature to be reduced to about 120 ℃ behind the product to inject next time again again, about 1.5 hours consuming time again, not only inefficiency, and power consumption is very big.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of rubber injection mold is provided, to solve inefficiency and the big problem of power consumption that existing rubber injection mold causes because of the restriction of the quantity of injection point and position.
The technical solution of the utility model is: a kind of rubber injection mold, it comprises the mold insert of framed, runner plate and formation umbrella page or leaf, runner plate and mold insert be installed in framed on, gum intaking passage is arranged on the runner plate, glue-feeder is arranged on the gum intaking passage, gum intaking passage is made up of two-stage at least, and each mold insert all has a gum intaking passage corresponding with it, and air discharge duct is arranged on the mold insert.
The further technical scheme of the utility model is: runner plate is the bulk flow guidance tape, and it is positioned at a side of mould.
The utility model more further technical scheme be: adopt the monolateral glue that advances, carry out exhaust from advancing each umbrella page or leaf of glue opposite.
The utility model further technical scheme is: carry out side and support entering the glue opposite, lower support is carried out in the bottom.
The utility model is owing to adopt monolateral each umbrella page or leaf to advance glue, sizing material enters fast from a side, and the structural design of opposite side exhaust can be full of mould to sizing material fast, each umbrella page or leaf advances glue, enough glue points that advances are arranged, can advance glue fast, and then can directly directly inject at curing temperature, compared with prior art, have that into glue speed is fast, good exhaust effect, molding time is short, the production efficiency height, characteristics such as low in energy consumption have only about 3 minutes inject time, because inject time is very short, just can directly under the curing temperature about 160 ℃, directly inject, can save inject time and temperature fall time, save about energy consumption 50KW, raise the efficiency 50%.
Description of drawings
Fig. 1 is the structural representation of existing rubber injection mold;
Fig. 2 is the structural representation of the utility model rubber injection mold.
Below in conjunction with figure and embodiment detailed structure of the present utility model is further described.
The specific embodiment
As shown in Figure 2, the utility model rubber injection mold comprises framed 1, the mold insert 3 of runner plate 2 and formation umbrella page or leaf, runner plate 2 and mold insert 3 are installed on framed 1, on the runner plate 2 gum intaking passage is arranged, glue-feeder 4 is arranged on the gum intaking passage, each glue-feeder 4 corresponding two one-level gum intaking passage 5, each one-level gum intaking passage 5 corresponding two secondary gum intaking passage 6, each secondary gum intaking passage 6 corresponding two three grades of gum intaking passage 7, each three grades of gum intaking passages, 7 corresponding two level Four gum intaking passage 8, each level Four gum intaking passage 8 corresponding mold inserts 3 that form the umbrella pages or leaves also are provided with lower support 9 on framed 1 and side supports 10, and air discharge duct 31 is arranged on the mold insert 3.
Operation principle of the present utility model and using method are: sizing material is expelled to mould one side die joint by the nozzle of rubber injection machine, runner plate 2 by an integral body, step by step sizing material is expelled on each umbrella page or leaf 9, sizing material can directly carry out fast injection from a side of mould at 160 ℃ curing temperature and enter, sizing material side direction opposite side from each umbrella page or leaf in mould is filled, the opposite side exhaust of each umbrella page or leaf, simultaneously support with side hollow insulator is supported entering the glue opposite, the bottom is supported with lower support, and is not eccentric to guarantee.
