Abstract
The invention discloses a light guide plate mould. The light guide plate mould comprises a lower mould, an upper mould arranged above the lower mould, an ejection rod hole formed in the bottom of the lower mould, a sealing strip arranged in the ejection rod hole, a mould cavity arranged in the lower mould, a material injection hole formed in the upper mould, an air exhausting hole which is formed in the upper mould and is communicated with the mould cavity, and a vacuum air pumping machine arranged at the top of the air exhausting hole, wherein the upper mould and the lower mould are matched to form a parting surface; the parting surface is provided with a sealing ring; a guide column is further arranged between the upper mould and the lower mould; the guide column is provided with a vibration absorption spring. With the adoption of the light guide plate mould, materials have no air resistance in the process of flowing in the mould cavity and the flowing is very smooth; no air exists in the mould cavity so that air bubbles in a product can be eliminated effectively; when the upper mould and the lower mould are closed, the vibration absorption spring can have a buffering effect and the mould is not damaged, so that the service life of the mould is prolonged.
Description
Technical field
The present invention relates to a kind of light-conducting board mold.
Background technology
In light-conducting board mold field, existing light-conducting board mold relatively simple for structure, is simple being comprised of upper die and lower die.During work, by after upper die and lower die matched moulds, directly with injection machine by the plastic-injection of melting in die cavity, form final product.There is following problem in this traditional mode:
1, in die cavity, lack sealing device, have air to exist, when plastic cement flows in die cavity like this, be subject to the impact of air drag, flow difficulties.
2, because there is the existence of air, in the final product forming, contain bubble, product quality declines.
3, during upper die and lower die matched moulds, Ccope closing machine speed is fast, easily causes die surface damage, breaks mould, so just greatly reduces the service life of light-conducting board mold.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly can effectively eliminate the residual air in die cavity when injection moulding, and during matched moulds, patrix and counterdie can perfect be fitted, and can prevent the light-conducting board mold that patrix and counterdie break.
For addressing the above problem, the present invention adopts following technical scheme: a kind of light-conducting board mold of the present invention, comprise bed die, and be arranged on the mold of bed die top, and be arranged on the jogger hole of bed die bottom, and be arranged on the sealing strip of jogger hole position, and be arranged on the die cavity in bed die, and be arranged on the material hole on mold, and be arranged on the steam vent being connected with die cavity in mold, and be arranged on the vacuum air pump on steam vent top, after coordinating with bed die, described mold forms die joint, described die joint is provided with sealing ring, between described mold and bed die, be also provided with a guide pillar, on described guide pillar, be provided with damping spring.
As preferred technical scheme, described guide pillar is divided into main part and guide part, and described damping spring is arranged on guide part outside, and described guide part end is taper seat.
As preferred technical scheme, described steam vent is provided with two, and is separately positioned on the both sides of material hole.
As preferred technical scheme, in described mold, be provided with the gathering sill matching with guide part.
The beneficial effect of light-conducting board mold of the present invention is: adopt this light-conducting board mold, material does not have the resistance of air while flowing in die cavity, flow very smooth and easy, and because there is no air in die cavity, can more effectively eliminate the bubble in product, when mold and bed die matched moulds, damping spring can play the effect of buffering, can not make mould break, improve the service life of mould.
Accompanying drawing explanation
For ease of explanation, the present invention is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of light-conducting board mold of the present invention.

The specific embodiment
Refer to shown in Fig. 1, a kind of light-conducting board mold of the present invention, comprise bed die 1, and be arranged on the mold 2 of bed die 1 top, and be arranged on the jogger hole 5 of bed die 1 bottom, and be arranged on the sealing strip 6 of jogger hole 5 positions, and be arranged on the die cavity 7 in bed die 1, and be arranged on the material hole 13 on mold 2, and be arranged on the steam vent 8 being connected with die cavity 7 in mold 2, and be arranged on the vacuum air pump 9 on steam vent 8 tops, after coordinating with bed die 1, described mold 2 forms die joint 3, described die joint 3 is provided with sealing ring 4, between described mold 2 and bed die 1, be also provided with a guide pillar, on described guide pillar, be provided with damping spring 12.
Wherein, described guide pillar is divided into main part 10 and guide part 11, and described damping spring 12 is arranged on guide part 11 outsides, and described guide part 11 ends are taper seat, damping spring 12 can play the effect of buffering, can not make mould break, and has improved the service life of mould; Described steam vent 8 is provided with two, and is separately positioned on the both sides of material hole 13, by steam vent 8, by the Bas Discharged in die cavity 7, in die cavity 7, there is no air, can more effectively eliminate the bubble in product; In described mold 2, be provided with the gathering sill 14 matching with guide part 11.
The beneficial effect of light-conducting board mold of the present invention is: adopt this light-conducting board mold, material does not have the resistance of air while flowing in die cavity, flow very smooth and easy, and because there is no air in die cavity, can more effectively eliminate the bubble in product, when mold and bed die matched moulds, damping spring can play the effect of buffering, can not make mould break, improve the service life of mould.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
