Description

The balanced runner structure of the injection mold of high reflection plastic-sealed body surface mount type LED support

Technical field

This utility model relates to LED support and makes art, refers in particular to a kind of high reflection plastic-sealed body adopting surface mounted LED and props up The balanced runner structure of the injection mold of frame.

Background technology

LED packaged light source device possesses high energy-conservation, profit environmental protection, life-span length, luminous efficiency high, uses widely In fields such as medical treatment, illuminations.And along with the development in market, the pursuit of light efficiency is improved constantly by client.In order to improve LED The luminous efficiency of light source and the heat dispersion of LED light source device, LED support is by continuous reformed AHP, thus thermoelectricity separates Product enter the popular visual field.High reflection plastic-sealed body surface mount type LED support is that a kind of LED that current performance is the most excellent props up Frame, this LED support needs to use to injection mold making, and owing to this injection mold is the more mould of die cavity number, passes The runner design of system is difficult to meet and balances into glue, cause same mould product some beaten full some also do not beat full, some long burr, have A little shrink, the problem such as some tired gas jaundice.

Utility model content

In view of this, this utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of high reflection The balanced runner structure of the injection mold of plastic-sealed body surface mount type LED support, it can effectively solve existing injection mold and enter glue not The problem of balance.

For achieving the above object, this utility model uses such as purgation technical scheme:

The balanced runner structure of the injection mold of a kind of high reflection plastic-sealed body surface mount type LED support, includes substrate, this base The surface of plate is arranged with one first sprue, at least two second sprues, at least two the 3rd sprue and multiple sub-runners；Two Second sprue two ends with the first sprue respectively connect, and the width of each second sprue is identical and less than the first sprue Width；Two the 3rd sprues end with two second sprues respectively connects, and the width of each 3rd sprue is identical and little Width in the second sprue；The plurality of sub-runner and the 3rd corresponding sprue connection, the plurality of sub-runner is along the 3rd main flow The spaced and parallel arrangement of bearing of trend in road, is provided with multiple sprue gate in each sub-runner, the plurality of sprue gate is along sub-runner The direction extended is intervally arranged, and the width near the sub-runner of the second sprue is less than the width of the sub-runner away from the second sprue Degree, the degree of depth near the sub-runner of the second sprue is less than the degree of depth of the sub-runner away from the second sprue.

As a kind of preferred version, the both sides of every one end of described first sprue are all communicated with aforementioned second main flow Road, each second sprue is all vertical with the first sprue；It is aforementioned that the both sides of the end of each second sprue are all communicated with one 3rd sprue, each 3rd sprue is all vertical with the second sprue.

As a kind of preferred version, the both sides of described each 3rd sprue are all communicated with multiple aforementioned sub-runner, each Sub-runner is all vertical with the 3rd sprue.

Less more than width and the degree of depth as the sprue gate in the sub-runner that a kind of preferred version, width and the degree of depth are bigger Sprue gate in sub-runner.

This utility model compared with prior art has clear advantage and beneficial effect, specifically, by above-mentioned technology Scheme understands:

By sub-runner is designed to different size by rule, a little bit smaller, away from second near the design of the second sprue The gradually increasing of sprue so that flow manifold is not of uniform size, to control the flow direction into glue and pressure, reaches the mesh into glue balance , make same mould product fill, it is to avoid long burr to occur, shrink and is stranded the problems such as gas jaundice simultaneously, it is simple to produce tune machine with The lifting of product quality.

For more clearly illustrating architectural feature of the present utility model and effect, it is right to come with specific embodiment below in conjunction with the accompanying drawings This utility model is described in detail.

Detailed description of the invention

Refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the preferred embodiment of this utility model, include Substrate 10, the surface of this substrate 10 is arranged with one first sprue 11, at least two second sprue 12, at least two the 3rd sprue 13 and multiple sub-runner 14.

Two second sprues 12 two ends with the first sprue 11 respectively connect, and the width of each second sprue 12 is identical And less than the width of the first sprue 11；Two the 3rd sprues 13 end with two second sprues 12 respectively connects, Mei Yi The width of three sprues 13 is identical and less than the width of the second sprue 12.In the present embodiment, described first sprue 11 it The both sides of every one end are all communicated with aforementioned second sprue 12, and each second sprue 12 all hangs down with the first sprue 11 Directly；The both sides of the end of each second sprue 12 are all communicated with aforementioned 3rd sprue 13, and each 3rd sprue 13 is equal Vertical with the second sprue 12.

The plurality of sub-runner 14 connects with the 3rd corresponding sprue 13, and the plurality of sub-runner 14 is along the 3rd sprue 13 The spaced and parallel arrangement of bearing of trend, is provided with multiple sprue gate 15 in each sub-runner 14, the plurality of sprue gate 15 is along shunting The direction that road 14 extends is intervally arranged, and, the width near the sub-runner 14 of the second sprue 12 is less than away from the second main flow The width of the sub-runner 14 in road 12, the degree of depth near the sub-runner 14 of the second sprue 12 is less than dividing away from the second sprue 12 The degree of depth of runner 14.In the present embodiment, the both sides of described each 3rd sprue 13 are all communicated with multiple aforementioned sub-runner 14, Each sub-runner 14 is all vertical with the 3rd sprue 13, and, the sprue gate 15 in width and the bigger sub-runner 14 of the degree of depth is big Sprue gate 15 in the sub-runner 14 that width and the degree of depth are less.

During use, melt plastic cement flows into the first sprue 11, each second sprue 12, each 3rd sprue 13 and each successively Sub-runner 14, the sprue gate 15 being then passed through correspondence flows in corresponding die cavity.

Design focal point of the present utility model is: by sub-runner is designed to different size by rule, main near second The design of runner is a little bit smaller, away from the gradually increasing of the second sprue so that flow manifold is not of uniform size, to control the stream into glue To with pressure, reach into glue balance purpose, make same mould product fill, it is to avoid long burr to occur, shrinks and be stranded gas simultaneously The problems such as jaundice, it is simple to produce the lifting of tune machine and product quality.

The above, be only preferred embodiment of the present utility model, not make technical scope of the present utility model Any restriction, thus every according to technical spirit of the present utility model, above example is made any trickle amendment, equivalent become Change and modify, all still falling within the range of technical solutions of the utility model.
