Secondary ejecting mechanism
[technical field]
The present invention relates to a kind of mould structure, be specifically related to a kind of secondary ejecting mechanism.
[background technology]
When producing plastic cement products, especially for shell series products, its shaping major part is at master mold.At mould
During die sinking, general a master mold glue degree of lip-rounding formula of hiding is used to carry out into glue, so the disengaging of runner and product is exactly
The emphasis of this type of mould.Master mold mechanism is easy-to-draw when hiding glue bad to produce for once ejecting of using in prior art
Product, use secondary ejecting mechanism, but add two pieces of liftout plates, waste again material while that structure being remarkable.
In view of this, being necessary in fact to provide a kind of secondary ejecting mechanism, this secondary ejecting mechanism can solve to draw material
The problem of Shi Yila bad product has saved two pieces of liftout plates simultaneously.
[summary of the invention]
In order to achieve the above object, the present invention provides a kind of secondary ejecting mechanism, and it is applied in mould, should
Mould includes: caster, male template, mother module core, male die core, upper ejector plate, lower liftout plate and lower fixing
Plate, this secondary ejecting mechanism includes:
First thimble, its one end penetrates this male template, and the other end of this first thimble is located in this upper ejector plate；
Second thimble, its one end penetrates this male template, and when matched moulds, the other end of this second thimble penetrates on this
Liftout plate and this lower liftout plate contact with this bottom plate；
Spacing card, it is snapped on this second thimble.
It is also preferred that the left described spacing card and described second thimble interference fits.
During this mould matched moulds, one end of this first thimble is stretched in die cavity through this male template and this male die core and is used
In ejecting product, one end of this second thimble is used for ejecting runner through this male template and this male die core.
During this mould die sinking, separately, this upper ejector plate and this lower liftout plate drive for this caster and this male template
This first thimble moves to die sinking direction, and now this second thimble is failure to actuate, thus this first thimble is by this product
Product depart from this runner, and this mould continues die sinking, until this upper ejector plate contacts with this spacing card, due to
The restriction of this spacing card, this first thimble and this second thimble continue to move to die sinking direction, respectively simultaneously
This product and this runner are ejected, completes and whole eject action.
Compared to prior art, present configuration is simple, practical, saves material, ejects at twice and make
Runner will not draw bad product easily, substantially increases product yield.
[accompanying drawing explanation]
Fig. 1 is schematically shown as the structural representation of secondary ejecting mechanism matched moulds state.
Fig. 2 is schematically shown as secondary ejecting mechanism the first die opening state structural representation.
Fig. 3 is schematically shown as secondary ejecting mechanism the second die opening state structural representation.
[detailed description of the invention]
Below with accompanying drawing, the better embodiment of the present invention is described in further detail.
Refer to shown in Fig. 1, the present invention provides a kind of secondary ejecting mechanism, and it is applied in mould, this mould
Tool includes: caster 50, male template 60, mother module core 51, male die core 61, upper ejector plate 70, under eject
Plate 80 and bottom plate 90, this secondary ejecting mechanism includes:
First thimble 30, its one end penetrates this male template 60, and the other end of this first thimble 30 is located on this
In liftout plate 70；
Second thimble 40, its one end penetrates this male template 60, the other end of this second thimble 40 when matched moulds
Penetrate this upper ejector plate 70 and this lower liftout plate 80 contacts with this bottom plate 90；
Spacing card 41, it is snapped on this second thimble 40.
Wherein, described spacing card 41 and described second thimble 40 interference fits.
During this mould matched moulds, one end of this first thimble 30 is stretched into through this male template 60 and this male die core 61
For ejecting product 10 in die cavity, one end of this second thimble 40 passes this male template 60 and this male die core 61
For ejecting runner 20.
Refer to shown in Fig. 2, during this mould die sinking, this caster 50 and this male template 60 are separated, on this
Liftout plate 70 and this lower liftout plate 80 drive this first thimble 30 to die sinking direction move, this runner 20 because of
Overhead kick on this mould cannot action, now this second thimble 40 also will not action, thus this first thimble 30
This product 10 being ejected die cavity be separated with this runner 20, this mould continues die sinking, until this upper ejector plate
70 contact with this spacing card 41.
Refer to shown in Fig. 3, due to the restriction of this spacing card 41 so that this upper ejector plate 70 drives should
Second thimble 40 moves to die sinking direction, and this first thimble 30 and this second thimble 40 continue to die sinking simultaneously
Moving in direction, this product 10 and this runner 20 is ejected respectively, completes and whole ejects action.
Compared to prior art, present configuration is simple, practical, saves material, ejects at twice and make
Runner will not draw bad product easily, is greatly improved the yield of product.
It is noted that the invention is not restricted to above-mentioned embodiment, any those skilled in the art's base
Any simple modification, equivalent variations and the modification made above-described embodiment in technical solution of the present invention, all falls
Enter in protection scope of the present invention.
