Abstract

The utility model discloses an injection mold flow passage flow control switch which comprises a first insert and a second insert; the end surface of the first insert is provided with a first flow passage cavity which is rotatably provided with one side of the parting surface of the mold; the second insert is rotatably matched with the first insert to realize the adjustment of the injection flow; the end surface of the second insert is provided with a second flow passage cavity which is rotatably provided with the other side of the parting surface of the mold; the first insert and the second insert are at least arranged under an opposite position state; the first flow passage cavity and the second flow passage cavity are closed for injection liquids to pass through. Compared with the prior art, the utility model has the advantages of convenient and quick operation, simple operation, easy mounting, and low manufacture cost.

Description

Injection mold runner flow control switch

Technical field

The utility model relates to a kind of injection mold runner flow control switch, and this gauge tap reaches the easily control and regulation of flow size.

Background technology

During the existing mold injection moulding, the a plurality of cast gates of common large-scale plastic parts exist uneven when die trial, and the weld mark position is undesirable etc., and problem is very outstanding, conventional way is on the phase of mold flow analysis plinth each gate size suitably to be reduced earlier, when die trial, progressively strengthen then, this way is time-consuming, effort, and the cast gate after strengthening sometimes such as undesirable rethinks and reduced just to become difficulty.

But also there is not special cast gate flow control switch to solve this problem at present.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of control injection mold runner flow control switch easily and fast at the above-mentioned state of the art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of injection mold runner flow control switch is characterized in that this switch comprises

First inserts, and end face has a first flow chamber, is provided with die joint one side of mould rotationally;

Second inserts, and above-mentioned first inserts and is rotatably assorted realizing the injection moulding Flow-rate adjustment, and this second end face of inserting has one second flow passage chamber, is provided with the die joint opposite side of mould rotationally,

Described first inserts and second inserts and be at least under the relative position state, and the first flow chamber and second flow passage chamber close, and pass through for the injection moulding fluid.

As improvement, described second flow passage chamber is provided with a choked flow post, and this choked flow post liftably is arranged at described second up and down and inserts upward to regulate the injection moulding fluid flow size by second flow passage chamber.The fine setting that can realize flow by the choked flow post like this.

As preferably, described first inserts and second inserts and be located at rotationally on the die joint of mould by screw separately respectively.Described choked flow post by helicitic texture liftably be arranged at second insert on.

Further, be convenient to moulding, the cross section of the described first flow chamber and second flow passage chamber is C shape or U-shaped.

Compared with prior art, advantage of the present utility model is: insert and the Fluid Volume that can pass through is regulated in second the rotation between inserting between the two by first, and convenient and swift, simple to operate, and, first insert and second installation of inserting on mould also very convenient, cheap for manufacturing cost.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment: with reference to figure 1, Fig. 2 and shown in Figure 3, flow control switch comprises that first 1 and second 2, the first 1 end faces of inserting of inserting of inserting have a first flow chamber 11 that is the C type, is located at die joint 7 die cavities one side of mould rotationally by screw 3,

Accordingly, second 2 end faces of inserting have second flow passage chamber 21 that is the C type, also be provided with die joint 7 cores one side of mould rotationally by screw 4, second flow passage chamber 21 from bottom to top is equipped with a choked flow post 22, and this choked flow post 22 liftably is arranged at second up and down by helicitic texture and inserts on 2 to regulate the injection moulding fluid flow size by second flow passage chamber 21.

With reference to figure 3 and shown in Figure 4, first flow chamber 11 is corresponding with second flow passage chamber 21 closes and when being positioned on the runner 6 simultaneously, flow maximum at this moment, and, can realize the fine setting of fluid flow by regulating choked flow post 22,

With reference to shown in Figure 5, second inserts behind 2 Rotate 180s °, and the first flow chamber 11 and second flow passage chamber 21 stagger, and have only first flow chamber 11 to be positioned on the runner, and at this moment flow is half state.

With reference to figure 6 and shown in Figure 7, first inserts 1 and second inserts behind the 2 equal Rotate 180s °, and not on runner 6, at this moment flow is zero, is in closed condition for the first flow chamber 11 and second flow passage chamber 21.

With reference to shown in Figure 8, mould 100 is provided with injection moulding runner 6, and runner 6 is provided with flow control switch 10, is used to regulate the flow size, facts have proved, this flow control switch is very effective, has dissemination widely in medium-and-large-sized mould.
