By the injection mold, the yield of one-time die assembly is greatly improved, the gating system is simplified, the runners and the sprue gates in the mold are reasonably arranged, and the cost and mold materials are effectively saved.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of injection mold, belong to the injection mold technical field.
Background technology
The injection moulding processing of existing plastic products is day by day ripe, and for some smaller mouldings, such as some diameters have only several millimeters sleeve.When processing this type workpiece, because be hollow in the middle of its, its die cavity is just by inserting and core is put together.Because the machining accuracy of this type moulding is than higher, the cost of mould is also bigger, and the space that its die cavity occupies on template is very little, has so not only wasted a large amount of costs and material, nor can satisfy the needs of industrial mass manufacture.So, in order to strengthen the product quantity of a matched moulds moulding, improve the output of injection moulding processing, meet the demands of production and living, the people in the industry has made a lot of effort, generally is a plurality of die cavities are set on template.But maximum matched moulds outputs also has only tens at present, and this is because this type sleeve workpiece is smaller; Corresponding die cavity shared space on template is also smaller; If the die cavity that adds is too many, the setting of running gate system has just become a very big problem; Also must supporting running gate system be set on the sprue gate of each die cavity, increase the injection moulding cost of processing greatly.
Summary of the invention
Technical problem to above-mentioned existence; The objective of the invention is: proposed a kind of injection mold of processing small sleeve; It can simplify running gate system, rationally arrange mould ingate and sprue gate when improving matched moulds output greatly; Effectively save cost and mold materials, produce moulding in batches.
Technical solution of the present invention is achieved in that a kind of injection mold of processing small sleeve, comprises cover half, dynamic model, core, inserts, between running gate system, nozzle, running channel, dynamic model shaping area, between the cover half shaping area and plug hole; On the said fixed half and moving half, through core with insert, form the moulding die cavity of moulding; Said cover half is provided with the nozzle that links to each other with running gate system; Said nozzle communicates with running channel; Be a plurality of between said dynamic model shaping area, and all distribution is fixed on the dynamic model; Be equipped with on the said cover half with the dynamic model shaping area between between the cover half shaping area that matches; All be provided with a plug hole between said every pair of shaping area; Said plug hole is positioned on the cover half, and plug hole all is positioned at the center between shaping area; Be equipped with a plurality of die cavities between said every pair of shaping area, and die cavity is arranged around plug hole annular display all; All be connected with a plurality of running channels on said each plug hole; The tail end of said running channel communicates with the sprue gate of die cavity; Material in the said running gate system injects in the die cavity between each shaping area via plug hole and running channel through nozzle.
Preferably, be eight between said cover half shaping area and between the dynamic model shaping area; Be equipped with eight die cavities between said every pair of shaping area.
Preferably, the running channel between said each shaping area is formed by first running channel and second running channel; First running channel between said each shaping area is four, and arranges around the plug hole annular with displaying; Said each first running channel all communicates with plug hole, and on the tail end of first running channel, all is connected with two second running channels; All connected first running channel of said each second running channel communicates, and the tail end of second running channel all communicates with the sprue gate of die cavity.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The injection mold of processing small sleeve of the present invention; Be provided with on dynamic model and the cover half between a plurality of shaping areas; Go up annular array a plurality of die cavities of arranging between each shaping area, only a plug hole need be set between each shaping area, each die cavity is poured into a mould through the running channel of annular array; So not only increase the output of a matched moulds greatly, increased substantially the output of injection moulding processing; Also simplify simultaneously the setting of running gate system greatly, efficiently solved the problem of rationally arranging at running gate system, running channel and sprue gate; In addition, the injection mold of processing small sleeve of the present invention, compacter more than the structure of injection mold in the prior art, practiced thrift mold materials greatly, bring very big economic benefit to production firm.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing l is the structural representation of cover half in the injection mold of the present invention;
Accompanying drawing 2 is the structural representation of dynamic model in the injection mold of the present invention;
Wherein: 1, cover half; 2, dynamic model; 3, die cavity; 4, between the dynamic model shaping area; 5, between the cover half shaping area; 6, plug hole; 7, first running channel; 8, second running channel.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of injection mold of processing small sleeve of the present invention like accompanying drawing 1,2, comprise cover half 1, dynamic model 2, core, insert, between running gate system, nozzle, first running channel 7, second running channel 8, dynamic model shaping area 4, between the cover half shaping area 5 and plug hole 6; On said cover half 1 and the dynamic model 2, through core with insert, form the moulding die cavity 3 of moulding; Said cover half 1 is provided with the nozzle that links to each other with running gate system; Said nozzle communicates with plug hole 6; 4 is eight between said dynamic model shaping area, and all distribution is fixed on the dynamic model 2; Be equipped with on the said cover half 1 with the dynamic model shaping area between between the 4 cover half shaping areas that match 5; All be provided with a plug hole 6 between said every pair of shaping area; Said plug hole 6 is positioned on the cover half 1, and plug hole 6 all is positioned at the center between shaping area; Be equipped with eight die cavities 3 between said every pair of shaping area, and die cavity 3 is arranged around plug hole 6 annular displays all; All be connected with four first running channels 7 on said each plug hole 6, and it arranges around plug hole 6 annulars with displaying; On the tail end of said each first running channel 7, all be connected with two second running channels 8; Said each second running channel 8 all with, first running channel 7 that connects on it communicates, and the tail end of second running channel 8 all communicates with the sprue gate of die cavity 3.
