Abstract

The invention discloses a flow channel structure of a die with one mold and a plurality of points, which comprises a slide block, a stop block and a plurality of sub-flow channels; wherein, the top part of the slide block is provided with a sprue bushing hole which goes through to the bottom part thereof and the bottom part of the sprue bushing hole is provided with upper half flow channels of a plurality of main flow channels by extending towards two sides; the stop block is arranged below the slide block and the top part of the stop block is provided with lower half flow channels of a plurality of main channels; the lower half flow channels of each main flow channel are respectively combined with the upper half flow channels of a main flow channel of the bottom part of the slide block to form a main flow channel; upper and lower parts of a plurality of sub-flow channels are respectively arranged on a core and a cavity and respectively extend from the main flow channel. Therefore, the previous design scheme that the die with one mold and a plurality of points can not be designed into a double-plate die is realized; the improvement of the flow channels shortens the total length of flow channels and effectively saves the raw materials; compared with three-plate dies, slabs are simple, which saves the order cost of slabs and shortens the production period.

Description

The flow passage structure of multi-point mould mould

[technical field]

The present invention is meant a kind of flow passage structure of multi-point mould mould especially about a kind of flow passage structure of mould.

[background technology]

For the mould of multi-point mould, when there was a plurality of inner slide its inside, because structure and space are limit, die was difficult to offer cold runner.Usually can adopt three template dies in such cases, shunt on stripper plate, the appropriate location is opened perpendicular runner and is drawn glue on the mother module core.

Please consult Fig. 1, Fig. 2 jointly, Fig. 1 is the flow passage structure schematic diagram of mould in an a kind of mould two caves of prior art, and Fig. 2 is the cut-away view of mould in an a kind of mould two caves of prior art.

As shown in the figure, this mould includes male model benevolence 10, mother module core 17, caster 18, stripper plate 19, also include slide block 15 and slide block bundle piece 14, product 13 is produced by this mould, wherein, on this caster 18, offer horizontal run 11, on this mother module core 17 and this caster 18, offer vertical runner 12, and on this male model benevolence 10, offer plastic emitting runner 16.

For three template dies that adopt following uneconomic place is arranged: the runner length overall of three template dies is longer, wastes too many raw material; Wire dot system advances the loss of glue laminated power greatly, influences moulding; Three plate mould structures are two template dies relatively, its have more a stripper plate and finding some, die holder also can strengthen, the cost height; Molding cycle is long.

In view of this, be necessary to develop a kind of flow passage structure of multi-point mould mould in fact, thereby for the design of mould of plastics provides a kind of new scheme, the design of two template dies of mould that before can't be designed to the multi-point mould of two template dies is achieved, because the improvement of runner, shorten the runner total length, effectively saved raw material; The mould base is simple than three template dies, has saved the Order Cost of mould base, and has shortened the production cycle.

[summary of the invention]

Therefore, the object of the present invention is to provide a kind of flow passage structure of multi-point mould mould, thereby for the design of mould of plastics provides a kind of new scheme, the design of two template dies of mould that before can't be designed to the multi-point mould of two template dies is achieved, because the improvement of runner, shorten the runner total length, effectively saved raw material; The mould base is simple than three template dies, has saved the Order Cost of mould base, and has shortened the production cycle.

For reaching above-mentioned purpose, the flow passage structure of multi-point mould mould of the present invention, this structure comprises:

One slide block bundle piece, its top offer a geat that is through to the bottom and claim trepanning, and this geat claims that extension is provided with first runner of some sprues to both sides in the trepanning bottom;

One block, it is located under the above-mentioned slide block bundle piece, and its top is provided with second runner of several sprues, and second runner of each sprue combines with first runner of slide block bundle piece bottom one sprue respectively and forms a sprue;

Some runners, two parts are located at respectively on the male and female die about it, and it is extended by a sprue respectively.

Compared to prior art, the flow passage structure of the multi-point mould mould of invention, for the design of mould of plastics provides a kind of new scheme, the design of two template dies of mould that before can't be designed to the multi-point mould of two template dies is achieved, because the improvement of runner, shorten the runner total length, effectively saved raw material; The mould base is simple than three template dies, has saved the Order Cost of mould base, and has shortened the production cycle.

For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[specific embodiment]

Please consult Fig. 3, Fig. 4, Fig. 5 jointly, Fig. 3 illustrates flow passage structure schematic diagram, Fig. 4 for the mould in an a kind of mould two caves of a preferred embodiment of the present invention and illustrates cut-away view, Fig. 5 for the mould in an a kind of mould two caves of a preferred embodiment of the present invention and illustrate local amplification decomposition figure into Fig. 3.

The flow passage structure of one mould, the two cave moulds of a preferred embodiment of the present invention, this structure comprises: a slide block bundle piece 25, it is located at 27 of slide blocks, these slide block bundle piece 25 tops offer a geat that is through to the bottom and claim trepanning 23, this geat claims trepanning 23 to claim cover to advance glue in order to geat to be installed, and this geat claims trepanning 23 bottoms to extend first runner 241 that is provided with two sprues 24; One block 29, it is located under the above-mentioned slide block bundle piece 25, these block 29 tops are provided with second runner 242 of two sprues 24, second runner 242 of each sprue 24 combines with first runner 241 of slide block bundle piece 25 bottoms one sprue 24 respectively and forms a sprue 24, and this sprue 24 claims geat the plastic cement direct fluid level of outflow in the trepanning 23; Article six, runner 28, two parts are located at respectively on mother module core 21 and the male model benevolence 20 about it, wherein per three runners 28 are extended by a sprue 24, and every runner 28 is respectively equipped with a plastic emitting runner 30, and each plastic emitting runner 30 is three parts in upper, middle and lower of corresponding product 26 respectively.

During design block 29, it is smooth and easy to have guaranteed that slide block 27 withdraws from, and enough strokes that withdraws from are arranged.The sprue 24 of on block 29 and slide block bundle piece 25, arranging.Perforate is to install adaptor on the slide block bundle piece 25.The same with other two template die, plastics flow into die cavity by plastic emitting runner 30 after flowing into die crossing current road by adaptor.Owing to can't avoid slide block and cause to design runner on the die time, all can create with reference to this.Be designed to two template dies after the employing, guarantee that plastics flow smoothly, to replace three higher template die designs of cost in the past.

Compared to prior art, the runner structure of the multi-point mould mould of invention is for the design of mould of plastics is carried Supply a kind of brand-new scheme, before can't be designed to the establishing of two template dies of mould of the multi-point mould of two template dies The meter scheme is achieved, because the runner total length has been shortened in the improvement of runner, has effectively saved raw material; The mould base is simple than three template dies, has saved the Order Cost of mould base, and has shortened the production cycle.
