Technical problem to be solved in the utility model is to provide a kind of stub bar that can prevent when ejection device and hiding into glue flow passage structure of fracture occurs.
To achieve these goals, the utility model adopts following technical scheme to be achieved: one is hidden into glue flow passage structure, comprise sprue and runner, described sprue is communicated with runner square crossing, between adjacent sprue and runner, arrange the auxiliary elastic arm with radian, described auxiliary elastic arm is communicated with sprue and runner.
Improve as one of the present utility model, described auxiliary elastic arm is symmetrical arranged along sprue or runner.
Improve as one of the present utility model, described auxiliary elastic arm is curve shape.
Improve as one of the present utility model, described auxiliary elastic arm is circular shape.
Improve as one of the present utility model, described auxiliary elastic arm is elliptic arc shape.
Improve as one of the present utility model, described sprue is connected with melt plastic cement stove.
Improve as one of the present utility model, the end of described runner is communicated with one and hides into point, described in hide into point be funnel type structure, described in hide into an end and be provided with cast gate.
Improve as one of the present utility model, under the crosspoint of described sprue and runner, vertical connection one ejects pipe, described in eject in pipe and be provided with thimble.
Compared with prior art, of the present utility model hiding into glue flow passage structure arranges the auxiliary elastic arm with radian between adjacent sprue and runner, described auxiliary elastic arm is communicated with sprue and runner, in runner during the stub bar generation deformation demoulding, the stub bar being arranged in sprue, runner and auxiliary elastic arm is made to connect into an entirety, the deformation power be subject to is comparatively even, prevents stub bar from rupturing.Even if stub bar ruptures in runner, assist the stub bar in elastic arm and sprue to also form a stub bar entirety, ejection device under the effect of thimble, prevent stub bar from falling in mold cavity and weigh mould wounded.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figures 3 to 5, of the present utility modelly hide into glue flow passage structure, comprise sprue 11 and runner 12, described sprue 11 is communicated with runner 12 square crossing, between adjacent sprue 11 and runner 12, arrange the auxiliary elastic arm 13 with radian, described auxiliary elastic arm 13 is communicated with sprue 11 and runner 12.Adopt above-mentioned technology, of the present utility model hiding into glue flow passage structure arranges the auxiliary elastic arm 13 with radian between adjacent sprue 11 and runner 12, described auxiliary elastic arm 13 is communicated with sprue 11 and runner 12, in runner 12 during the stub bar generation deformation demoulding, the stub bar being arranged in sprue 11, runner 12 and auxiliary elastic arm 13 is made to connect into an entirety, the deformation power be subject to is comparatively even, prevents stub bar from rupturing.Even if stub bar ruptures in runner 12, assist the stub bar in elastic arm 13 and sprue 11 to also form a stub bar entirety, ejection device under the effect of thimble 15, prevent stub bar from falling in mold cavity 16 and weigh mould wounded.
Of the present utility modelly hide in glue flow passage structure, the end of described runner 12 is communicated with one and hides into point 14, describedly to hide into point 14 for funnel type structure, described hiding into point 14 ends is provided with cast gate, the accent of described mold cavity 16 is aimed at by cast gate, employing is hidden into glue mode and is poured into a mould, and in runner 12, stub bar deformation demoulding under the effect that ejects of thimble 15, realizes better stripping result.
Of the present utility modelly hide in glue flow passage structure, under the crosspoint of described sprue 11 and runner 12, vertical connection one ejects pipe 17, described in eject in pipe 17 and be provided with thimble 15.Eject effect by thimble 15, the stub bar entirety being arranged in sprue 11, runner 12 and auxiliary elastic arm 13 is ejected, simple and quick.
Of the present utility modelly hide in glue flow passage structure, described auxiliary elastic arm 13 is axial symmetry setting, and symmetry axis is sprue 11 and runner 12, has decomposed the deformation power of runner 12, make the stub bar in sprue 11, runner 12 and auxiliary elastic arm 13 form an entirety, and not easily rupture.
Preferably, of the present utility modelly hide in glue flow passage structure, auxiliary elastic arm 13 adopts curve, circular arc or elliptic arc shape, the linear of original runner 12 is improved as the geometrical curve shape of auxiliary elastic arm 13, make the holding capacity of stub bar more even, and not easily rupture.
With reference to shown in Fig. 3 to Fig. 5, the course of work of the present utility model will be described in detail below:
First, of the present utility modelly hide into glue flow passage structure between two accents of mold cavity 16, described in the cast gate of hiding into point 14 ends aim at the accent of described mold cavity 16, and described cast gate enters glue in the side of mold cavity 16 or the inside.
When plastic cement is poured into a mould, described sprue 11 is communicated with melt plastic cement stove, and melt plastic cement flows into sprue 11, is flowed in the runner of runner 12 and auxiliary elastic arm 13 by sprue 11, flows in mold cavity 16 finally by the cast gate of hiding into point 14 ends.Start to carry out plastic cement cast.
After plastic cement casting complete, the die at sprue 11 and runner 12 place is carried out parting, the stub bar being arranged in sprue 11, runner 12 and auxiliary elastic arm 13 connects into an entirety.Then, eject the thimble 15 upwards jack-up arranged in pipe 17 described in using, under the effect of thimble 15, make stub bar ejection device.In runner 12 during the stub bar generation deformation demoulding, the stub bar being arranged in sprue 11, runner 12 and auxiliary elastic arm 13 connects into an entirety, and the deformation power be subject to is comparatively even, prevents stub bar from rupturing.Even if stub bar ruptures in runner 12, assist the stub bar in elastic arm 13 and sprue 11 to also form a stub bar entirety, ejection device under the effect of thimble 15, prevent stub bar from falling in mold cavity 16 and weigh mould wounded.
Obviously, those skilled in the art can carry out various change and modification to invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
