A kind of injection mold that Fig. 2 ~ Fig. 5 provides for the utility model embodiment, comprise the front mould 1 and rear mold 2 that are oppositely arranged, multiple side form 3 is provided with between front mould 1 and rear mold 2, front mould 1, rear mold 2 and the closed die cavity 4 surrounding described injection mold of multiple side form 3, die cavity 4 plastic go out product 5, rear mold 2 comprises core 21, core 21 is relative with front mould 1, die cavity 4 around core 21 around, through hole 22 is provided with in rear mold 2, one end of side form 3 is between through hole 22 and die cavity 4, through hole 22 is not communicated with die cavity 4, on the bearing of trend being positioned at through hole 22 at least partially of die cavity 4, impeller 6 is provided with in through hole 22, when front mould 1, when rear mold 2 and side form 3 are separated, impeller 6 can move to the direction near product 5 and promote product 5 along through hole 22, thus product 5 is separated with core 21.
A kind of injection mold that the utility model embodiment provides, due to front mould 1, rear mold 2 and the closed die cavity 4 surrounding injection mold of multiple side form 3, and one end of side form 3 is between through hole 22 and die cavity 4, through hole 22 is not communicated with die cavity 4, namely the impeller 6 in through hole 22 is not as a part for die cavity 4, therefore, in the forming process of product 5, impeller 6 does not directly contact with the plastics of melting, thus avoid impeller 6 leave trace on the product 5 molded, in addition, because through hole 22 is not communicated with die cavity 4, fit clearance between through hole 22 and impeller 6 increases on the product 5 that also can not cause molding in die cavity 4 and produces burr, thus drastically reduce the area the workload of post-processed, the production cost of product 5 is significantly reduced.
In order to ensure that product 5 can be ejected, through hole 22 in the present embodiment and impeller 6 are multiple, multiple through hole 22 is arranged around core 21, multiple impeller 6 one_to_one corresponding is arranged in multiple through hole 22, thus, multiple impellers 6 can promote the different parts of product 5, make each position of product 5 all can be subject to thrust, thus ensure that product 5 can be ejected.
On the basis of above-described embodiment, multiple through hole 22 is evenly arranged, thus, make the stressed of each position of product 5 evenly, thus product 5 can be ejected fast, enhance productivity.
In order to save labour turnover, injection mold in the present embodiment also comprises the first drive unit (not shown), impeller 6 is connected with described first drive unit away from one end of side form 3, described first drive unit can drive impeller 6 to move along through hole 22, thus is ejected by product 5.Drive impeller 6 to move by the first drive unit, significantly can shorten the time of manpower management and control in batch production, thus cost of labor is reduced.
With reference to Fig. 4, in order to mold the higher product of precision, front mould 1 is relative with the end face of rear mold 2, the side of front mould 1 and/or rear mold 2 is provided with detent 7, side form 3 is provided with positioning convex 8, and positioning convex 8 is equipped with in detent 7, is accurately located side form 3 by the cooperation of positioning convex 8 and detent 7, thus the precision of the die cavity 4 making side form 3 surround with front mould 1 and rear mold 2 is higher, therefore, it is possible to mold the higher product of precision.
In order to save labour turnover, improve the precision of product, side form 3 is connected with the second drive unit (not shown) simultaneously, described second drive unit can drive side form 3 near or away from the direction translation of core 21.Drive side form 3 to move by the second drive unit, significantly can shorten the time of manpower management and control on the one hand, save labour turnover, the precision of side form 3 movement can be ensured on the other hand, reduce error, thus make the precision of die cavity 4 higher, the precision of the product molded is higher.
With reference to Fig. 4, in order to reduce use cost while saving labour turnover, side form 3 in the present embodiment comprises protuberance 31, protuberance 31 is relative with the side of front mould 1 and/or rear mold 2, elastic component (not shown) is provided with between the side of protuberance 31 and front mould 1 or rear mold 2, when described injection mould closing, protuberance 31 is connected with the 3rd drive unit (not shown), described 3rd drive unit can drive protuberance 31 to move to the direction near core 21, described elastic component is made to be compressive state, when described injection mold die sinking, protuberance 31 and described 3rd drive unit disconnect, now, elastic component drives side form 3 to the direction translation away from core 21 by elastic force.Drive side form 3 to the direction translation near core 21 by the 3rd drive unit, can save labour turnover, reduce error, drive side form 3 to the direction translation away from core 21 by the elastic force of elastic component, the access times of the 3rd drive unit can be reduced, thus reduce use cost.
Because elastic component is arranged between the side of protuberance 31 and front mould 1 or rear mold 2, therefore, the length of elastic component is longer, the space that injection mold takies is larger, in order to the impact that the length reducing elastic component takes up room on injection mold, with reference to Fig. 6, the surface that the side of the protuberance 31 in the present embodiment and front mould 1 or rear mold 2 is relative is provided with installing hole 32, one end of described elastic component is connected with the inwall of installing hole 32, and the other end is squeezed on the side of front mould 1 or rear mold 2.Thus, when described injection mould closing, 3rd drive unit drives side form 3 to the direction translation near core 21, and part or all of elastic component can be pressed in installing hole 32 by the side of front mould 1 or rear mold 2, thus the impact that the length reducing elastic component takes up room on injection mold.
Concrete, injection mold in the utility model embodiment can be used for the shaping of glue frame in backlight module, backlight module is one of critical component of display panels, because liquid crystal itself is not luminous, the function of backlight module, mainly for liquid crystal panel provides sufficient brightness and the light source be evenly distributed, normally can show image.Backlight module is formed by assembling components such as backlight, blooming piece and glue frames, and glue frame, can fixed optics diaphragm as structural member important in backlight module, can cover again the light of marginal ray and lamp position.The material of glue frame can be Merlon, by polycarbonate pellets by being expelled in die cavity 04 after the gun barrel intensification plasticizing of injection machine, can obtain glue frame after cooling.
Without push rod print and burr on the glue frame that the injection molded provided by the utility model is gone out, therefore, the assembling of miscellaneous part can not be had influence on, the instructions for use of backlight module can be met, considerably reduce the workload of post-processed, the manufacturing cycle of frame glue and cost are significantly reduced.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
