Abstract

The invention discloses a double-sprue plastic injection mold capable of automatically controlling flow. The double-sprue plastic injection mold comprises a mold body, wherein a left sprue and a right sprue are formed in the upper end face of the mold body; flow control valves are respectively mounted above the left sprue and the right sprue; a mold cavity is formed inside the mold body; a metal plate is arranged below the mold cavity; a weight sensing device is arranged below the metal plate; the weight sensing device is composed of weight sensors, a tray and a support rod; the tray is in contact with the metal plate; the support rod is fixedly mounted under the center of the tray; the weight sensors are fixedly mounted on the two sides of the tray, and are connected with the flow control valves through data connecting lines. Through the manner, the flow of pouring materials at the sprues can be automatically adjusted according to the fact whether the weight distribution inside the mold cavity is balanced or not.

Description

Can the double cast gate injection mold of automatic control flow
Technical field
The present invention relates to a kind of mould applications, particularly a kind of can the double cast gate injection mold of automatic control flow.
Background technology
Along with improving constantly of science and technology, die industry is also more and more flourishing, and mould is subject to vast manufacturer as a kind of manufacturer's standard part device used to be favored, and the injection moulding process of injection mold is that the material melted that is heated is injected die cavity by high pressure, after cooling curing, obtain formed products, present stage, in the injection moulding process of mould, after melted material enters die cavity, distribution is even not, often causes the products formed after cooled and solidified to occur defect, percent defective is high, cost of idleness.
Summary of the invention
The technical problem that the present invention mainly solves be to provide a kind of can the double cast gate injection mold of automatic control flow, can according to the whether balanced flow automatically regulating cast gate place mould material of die cavity weight inside distribution.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of can the double cast gate injection mold of automatic control flow, comprise: die body, the upper surface of described die body is provided with left and right two cast gates, described in left and right two, the top of cast gate is all provided with flow control valve, the inside of described die body is provided with die cavity, the below of described die cavity is provided with a metallic plate, the below of described metallic plate is provided with weight induction device, described weight induction device is by weight induction device, pallet and support bar are formed, described pallet contacts with described metallic plate, described support bar is fixedly mounted on immediately below tray center, described weight induction device is fixedly mounted on the both sides of described pallet, and be connected with described flow control valve by data connecting line.
In a preferred embodiment of the present invention, described metallic plate is corrosion resistant plate, improves hardness, intensity and resistance to elevated temperatures.
In a preferred embodiment of the present invention, described data connecting line is positioned at the outside of described die body, is that data connecting line is tried one's best away from melted material, prevents from being subject to high temperature and damaging.
The invention has the beneficial effects as follows: the present invention is by adopting the injection mold of double cast gate, and two cast gate places be all provided with die body bottom the flow control valve that is connected of the mass sensor that is provided with, emotion can be created by quality and the distribution situation of melted material in die cavity is fed back to flow control valve, thus the flow proportional at controlled quentity controlled variable cast gate place, thus realize the homogenising of melted material distribution in die cavity.
Accompanying drawing explanation
Fig. 1 is the present invention's structural scheme of mechanism in a preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, die body, and 2, die cavity, 3, cast gate, 4, flow control valve, 5, metallic plate, 6, pallet, 7, support bar, 8, quality inductor.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of can the double cast gate injection mold of automatic control flow, comprise: die body 1, the upper surface of described die body 1 is provided with left and right two cast gates 3, described in left and right two, the top of cast gate 3 is all provided with flow control valve 4, the inside of described die body 1 is provided with die cavity 2, the below of described die cavity 2 is provided with a metallic plate 5, the below of described metallic plate 5 is provided with weight induction device, described weight induction device is by weight induction device 8, pallet 6 and support bar 7 are formed, described pallet 6 contacts with described metallic plate 5, described support bar 7 is fixedly mounted on immediately below pallet 6 center, weight induction device 8 is fixedly mounted on the both sides of described pallet 6, and be connected with described flow control valve 4 by data connecting line,
Wherein, described metallic plate 5 is corrosion resistant plate, improves hardness, intensity and resistance to elevated temperatures;
Described data connecting line is positioned at the outside of described die body 1, is that data connecting line is tried one's best away from melted material, prevents from being subject to high temperature and damaging;
Be different from prior art, present invention is disclosed a kind of can the double cast gate injection mold of automatic control flow, its specific works flow process is: first the flow proportional of two flow control valves 4 is adjusted to 1:1, then in two sprue gates 3, melted material is poured into a mould, along with melted material flows in the die cavity 2 of die body 1 inside along sprue gate 3, along with melted material is shaping in die cavity 2 inner dispersion, weight induction device by metallic plate 5 by weight transmitting to the weight induction device 8 being positioned at pallet 6 both sides, weight induction device 8 induces the mass ratio of the inner both sides of die cavity 2 respectively by support bar 7, then flow control valve 4 is fed back to by data connecting line, the message flow automatic regulation ratio of flow control valve 4 by obtaining, make the melted material entering the left and right sides can will be positioned at the inner homogenize material pockety of die cavity 2, by the way, the present invention can according to the whether balanced flow automatically regulating cast gate place mould material of die cavity weight inside distribution, improve Forming Quality.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
