Description
Technical field
This utility model relates to injection mold technical field, particularly to a kind of light-conducting board mold improved structure.
Background technology
The electronic product such as mobile phone, computer all can use light guide plate.Light guide plate to accomplish enough flat smooth, not so can affect
Display effect.Light guide plate, when injection mo(u)lding, typically uses mould two chamber or the mode of multi-cavity.After molding completes, by craft
Regrinding-material is broken disconnected with light guide plate product, makes product separate.Existing light-conducting board mold die cavity typically processed by gong bed or
Use electrical discharge machining process, thus make the dimensional accuracy at mould glue-feeder be difficult to ensure that, the glue-feeder of different die cavities
Scale error is relatively big, and stands angle at glue-feeder and be difficult to ensure that, it is difficult to accomplish enough sharp-pointed, be unfavorable for product and regrinding-material point
From, it may occur that the bad problems such as wound are cut out at the mouth of a river.
Utility model content
Main purpose of the present utility model is to provide a kind of light-conducting board mold improved structure, it is intended to improve at mould glue-feeder
Dimensional accuracy, the vertical angle solving glue-feeder is sharp-pointed not and the technical problem of wound is cut out at that the cause mouth of a river.
For achieving the above object, the utility model proposes a kind of light-conducting board mold improved structure, including being arranged in template
Acupuncture point, the mouth of a river and at least one product die cavity, this acupuncture point, mouth of a river and each product die cavity connection are gate part, in this template
The bottom of corresponding each gate part arranges a mouth of a river mold insert, and this mouth of a river mold insert includes mold insert top and mold insert root, this mold insert root
Portion is fixed in template, and this mold insert top has the sloped top face gradually narrowed towards corresponding product die cavity side, this mold insert root
Portion also has the location division that side is protruded.
Preferably, this template arranging two product die cavities, these two product die cavities are symmetrically distributed in the two of acupuncture point, the mouth of a river
Side.
Preferably, the sloped top face of this mouth of a river mold insert uses grinding machine processing.
Technical solutions of the utility model are by using independent mouth of a river mold insert to cooperatively form the type that gate part gradually narrows
Cavity configuration, is processed because mouth of a river mold insert can individually be taken out, and the cavity structure of gate part can be made to obtain higher precision,
So that the vertical angle at mould glue-feeder is more sharp-pointed, in order to regrinding-material and product separation, and ensure that Different Acupoint
The light guide plate of molding structure at gate location is basically identical, solves the mouth of a river and cuts out the bad problems such as wound.

The realization of this utility model purpose, functional characteristics and advantage will in conjunction with the embodiments, are described further referring to the drawings.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into the scope of this utility model protection.
It is to be appreciated that directional instruction (such as up, down, left, right, before and after ...) in this utility model embodiment
It is only used for explanation relative position relation under a certain particular pose (as shown in drawings) between each parts, motion conditions etc., as
When really this particular pose changes, then directionality instruction changes the most therewith.
It addition, the description relating to " first ", " second " etc. in this utility model is only used for describing purpose, and it is not understood that
For indicating or imply its relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ",
The feature of " second " can express or implicitly include at least one this feature.It addition, the technical side between each embodiment
Case can be combined with each other, but must be based on those of ordinary skill in the art are capable of, when the combination of technical scheme
Occur conflicting people to think that the combination of this technical scheme does not exists when maybe cannot realize, do not want at this utility model
Within the protection domain asked.
This utility model provides a kind of light-conducting board mold.
Referring to figs. 1 through 3, the formwork structure schematic diagram of the light-conducting board mold that Fig. 1 provides for this utility model one embodiment；Figure
The partial sectional view that 2 is the template shown in Fig. 1；Fig. 3 is the structure for amplifying schematic diagram of mouth of a river mold insert.
This light-conducting board mold uses a mould two cave structure, i.e. arranges two product die cavities 2 and cave, a mouth of a river in template 1
Position 3, these two product die cavities 2 are symmetrically distributed in the both sides at acupuncture point, the mouth of a river 3.This acupuncture point, mouth of a river 3 with product die cavity 2 connection is
Gate part 31.In this template 1, the bottom of corresponding each gate part 31 arranges a mouth of a river mold insert 4.This mouth of a river mold insert 4 is generally cylindrical
Structure, including mold insert top 41 and mold insert root 42.This mold insert root 42 is fixed in template 1.This mold insert top 41 have to
The sloped top face 43 that corresponding product die cavity 2 side is gradually narrowed, in order to form gate part 31 and gradually receive towards product die cavity 2
Narrow pouring gate structure.This mold insert root 42 also has the location division 44 that side is protruded, for the location of this mouth of a river mold insert 4 and solid
Fixed.
Technical solutions of the utility model are by using independent mouth of a river mold insert 4 to cooperatively form what gate part 31 gradually narrowed
Cavity structure, is processed because mouth of a river mold insert 4 can individually be taken out, and the cavity structure of gate part 31 can be made to obtain higher
Precision, so that the vertical angle at mould glue-feeder is more sharp-pointed, in order to regrinding-material and product separation, and ensure that difference
The light guide plate of acupuncture point molding structure at gate location is basically identical, solves the mouth of a river and cuts out the bad problems such as wound.
Preferably, the sloped top face 43 of this mouth of a river mold insert 4 uses grinding machine to process.
Use grinding machine processing that this sloped top face 43 can be made to obtain higher precision, in order to be formed between cast gate and product
More sharp-pointed vertical angle, it is simple to separate with gate materials after formed product, and do not damage light guide plate product.
In other embodiments, this template can also arrange multiple product die cavity 2, entering of corresponding each product die cavity 2
Jiao Kou position is both provided with corresponding mouth of a river mold insert 4.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every under inventive concept of the present utility model, the equivalent structure utilizing this utility model description and accompanying drawing content to be made becomes
Change, or directly/be indirectly used in other relevant technical fields and be included in scope of patent protection of the present utility model.
