The invention relates to a secondary ejecting mechanism applied in dies. The secondary ejecting mechanism comprises: a first ejector plate that is mounted on a lower fixed plate of a die and is provided with a first upper ejector plate and a first lower ejector plate; a second ejector plate that is disposed on a support bar of the die and provided with a second upper ejector plate and a second lower ejector plate; a limiting bar equipped with a damping part, with one end of the limiting bar positioned in the second ejector plate and the other end positioned in a female template of the die; a control bar, which has one end installed in the lower fixed plate of the die and the other end installed in the second ejector plate, as well as an outer rim sleeved with an elastic sleeve, one end of which is mounted in the first ejector plate and the other end of which is positioned in the limiting bar. The secondary ejecting mechanism of the invention has the advantages of simple structure, great ejection force, as well as good reliability and durability.
Description
[technical field]
The present invention relates to a kind of ejecting mechanism, be specifically related to a kind of secondary ejecting mechanism.
[background technology]
Mould is when producing plastic cement products at present, and the specialities structure needs secondary to eject or repeatedly ejects.
Existing secondary ejecting mechanism has: adopt the secondary ejecting mechanism of trip form, this mechanism's more complicated; Adopt the secondary ejecting mechanism of resin shutter, this mechanism is easy to wear, eject be prone to lose efficacy and ejecting force little; Adopt the secondary ejecting mechanism of form of springs, this mechanism generally is used for single-unit activity to be gone into son and does local secondary and eject, but spring is compressed the back owing to there is not starting power, can not eject synchronously with product, causes breaking of product to pull.
In view of this, in fact be necessary to develop a kind of novel secondary ejecting mechanism, this secondary ejecting mechanism is simple in structure, and ejecting force is big, and reliability and durability are good.
[summary of the invention]
Therefore, the purpose of this invention is to provide a kind of secondary ejecting mechanism, this secondary ejecting mechanism is simple in structure, and ejecting force is big, and reliability and durability are good.
In order to achieve the above object, secondary ejecting mechanism of the present invention, it is applied in the mould, and this mould comprises: bottom plate, male model plate, caster, support bar, this secondary ejecting mechanism comprises:
One first liftout plate, it is located on the bottom plate of above-mentioned mould, and this first liftout plate is provided with one first upper ejector plate and one first time liftout plate;
One second liftout plate, it is located on the support bar of above-mentioned mould, and this second liftout plate is provided with one second upper ejector plate and one second time liftout plate;
One gag lever post, one of which end are located in above-mentioned second liftout plate, and the other end is located in the caster of mould, and this gag lever post is provided with a retaining portion;
One control lever, one of which end are located in the bottom plate of mould, and the other end is located in above-mentioned second liftout plate, and the outer rim of this control lever is arranged with a resilient sleeve, and this resilient sleeve one end is located in above-mentioned first liftout plate, and the other end is located in the above-mentioned gag lever post.
Compared to prior art, secondary ejecting mechanism of the present invention is simple in structure, and ejecting force is big, and reliability and durability are good.
[description of drawings]
Fig. 1 illustrates the sketch map of secondary ejecting mechanism of the present invention.
Fig. 2 illustrates the sketch map that ejects for the first time of secondary ejecting mechanism of the present invention.
Fig. 3 illustrates the local enlarged diagram that ejects for the first time of secondary ejecting mechanism of the present invention.
Fig. 4 illustrates the sketch map that ejects for the second time of secondary ejecting mechanism of the present invention.
[specific embodiment]
See also shown in Figure 1ly, it illustrates the sketch map of secondary ejecting mechanism of the present invention.
Secondary ejecting mechanism of the present invention, it is applied in the mould, and this mould comprises: bottom plate 10, male model plate 20, caster (figure does not show), support bar 30, this secondary ejecting mechanism comprises:
One first liftout plate 100, it is located on the bottom plate 10 of above-mentioned mould, and this first liftout plate 100 is provided with one first upper ejector plate 110 and one first time liftout plate 120;
One second liftout plate 200, it is located on the support bar 30 of above-mentioned mould, and this second liftout plate 200 is provided with one second upper ejector plate 210 and one second time liftout plate;
One gag lever post 300, one of which end are located in above-mentioned second liftout plate 200, and the other end is located in the caster (figure does not show) of mould, and this gag lever post 300 is provided with a retaining portion 310;
One control lever 400; The one of which end is located at through screw in the bottom plate 10 of mould, and the other end is located in above-mentioned second liftout plate 200, and the outer rim of this control lever 400 is arranged with a resilient sleeve 500; These resilient sleeve 500 1 ends are located in above-mentioned first liftout plate 100; The other end is located in the above-mentioned gag lever post 300, and this resilient sleeve 500 provides the motion mode that ejects for the first time when not being compressed, and after it is compressed, realizes ejecting for the second time.
Please consult Fig. 2 and shown in Figure 3 simultaneously, after the mould die sinking, under the promotion of mould board push rod; First liftout plate 100 is done and is ejected motion; Second liftout plate 200 and first liftout plate 100 eject jointly under the effect of control lever 400 and resilient sleeve 500, and gag lever post 300 moves upward simultaneously, after gag lever post 300 moves to its retaining portion 310 and the male model plate 20 of mould contacts; Gag lever post 300 receives the drag effect of male model plate 20 and no longer moves, and ejects completion for the first time;
See also shown in Figure 4; After for the first time ejecting completion, under the promotion of mould board push rod, first liftout plate 100 continues upwards to eject motion; Second liftout plate 200 was static when first liftout plate 100 ejected; Resilient sleeve 500 break away from that control levers 400 are compressed and in gag lever post 300 in contract, when first liftout plate 100 moves to after second liftout plate 200 contacts, eject completion for the second time;
When the mould matched moulds; First liftout plate 100 resets under the effect of the back-moving spring of mould; Above-mentioned resilient sleeve 500 is stretched; Second liftout plate 200 resets under the effect of the tensile force of above-mentioned resilient sleeve 500 simultaneously, and this first liftout plate 100 and second liftout plate 200 reset under the effect of mold clamping force then.
Compared to prior art, secondary ejecting mechanism of the present invention is simple in structure, and ejecting force is big, and reliability and durability are good.
