Abstract

The invention provides a novel secondary ejection mechanism which is applied to a mold. The mold comprises a female mold board, a male mold board, a cavity insert, a core insert, an upper ejector board, a lower ejector board and a lower fixing plate; the novel secondary ejection mechanism comprises a first thimble, a second thimble and a limit clamping piece, wherein one end of the first thimble penetrates through the male mold board, the other end of the first thimble is arranged in the upper ejector board, one end of the second thimble penetrates through the male mold board, the other end of the second thimble penetrates through the upper ejector plate and the lower ejector plate to be contacted with the lower fixing plate during mold closing, and the limit clamping piece is buckled on the second thimble. Compared with the prior art, the novel secondary ejection mechanism has a simple structure and strong practicability and can perform ejection for two times, so that a product is difficult to damage due to pulling in a runner and the product yield is greatly improved.

Description

Novel 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 moulding major part is at master mold.When mould die sinking, generally adopt a master mold glue degree of lip-rounding formula of hiding to enter glue, so the disengaging of runner and product is exactly the emphasis of this type of mould.Available technology adopting once eject master mold mechanism easy-to-draw bad product when hiding glue, adopt secondary ejecting mechanism, but increased by two liftout plates, the remarkable while of structure is wasted again material.
In view of this, be necessary to provide a kind of novel secondary ejecting mechanism, this novel secondary ejecting mechanism to solve in fact draws the problem of easy-to-draw bad product while expecting to save two liftout plates simultaneously.
[summary of the invention]
In order to achieve the above object, the invention provides a kind of novel secondary ejecting mechanism, it is applied in mould, and this mould comprises: caster, male model plate, mother module core, male die core, upper ejector plate, lower liftout plate and bottom plate, and this novel secondary ejecting mechanism comprises:
The first thimble, its one end penetrates this male model plate, and the other end of this first thimble is located in this upper ejector plate;
The second thimble, its one end penetrates this male model plate, and when matched moulds, the other end of this second thimble penetrates this upper ejector plate and this lower liftout plate contacts with this bottom plate;
Spacing card, it is snapped on this second thimble.
Preferably, described spacing card and described the second thimble interference fits.
During this mould matched moulds, one end of this first thimble is stretched in die cavity for ejecting product through this male model plate and this male die core, and one end of this second thimble is used for ejecting runner through this male model plate and this male die core.
During this mould die sinking, this caster and this male model plate are separately, this upper ejector plate and this lower liftout plate drive this first thimble to move to die sinking direction, now this second thimble is failure to actuate, thereby this first thimble departs from this product and this runner, this mould continues die sinking, until this upper ejector plate contacts with this spacing card, restriction due to this spacing card, this first thimble and this second thimble continue to move to die sinking direction simultaneously, respectively this product and this runner are ejected, completed the whole action that ejects.
Compared to prior art, the present invention is simple in structure, practical, saves material, ejects at twice and makes runner can not draw easily bad product, has greatly improved product yield.
[accompanying drawing explanation]
Fig. 1 illustrates the structural representation into novel secondary ejecting mechanism matched moulds state.
Fig. 2 illustrates as novel secondary ejecting mechanism the first die opening state structural representation.
Fig. 3 illustrates as novel secondary ejecting mechanism the second die opening state structural representation.
[specific embodiment]
Below with accompanying drawing, better embodiment of the present invention is described in further detail.
Please refer to shown in Fig. 1, the invention provides a kind of novel secondary ejecting mechanism, it is applied in mould, and this mould comprises: caster 50, male model plate 60, mother module core 51, male die core 61, upper ejector plate 70, lower liftout plate 80 and bottom plate 90, and this novel secondary ejecting mechanism comprises:
The first thimble 30, its one end penetrates this male model plate 60, and the other end of this first thimble 30 is located in this upper ejector plate 70;
The second thimble 40, its one end penetrates this male model plate 60, and when matched moulds, the other end of this second thimble 40 penetrates 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 the second thimble 40 interference fits.
During this mould matched moulds, one end of this first thimble 30 is stretched in die cavity for ejecting product 10 through this male model plate 60 and this male die core 61, one end of this second thimble 40 through this male model plate 60 and this male die core 61 for ejecting runner 20.
Please refer to shown in Fig. 2, during this mould die sinking, this caster 50 and this male model plate 60 are separately, this upper ejector plate 70 and this lower liftout plate 80 drive this first thimble 30 to move to die sinking direction, this runner 20 cannot move because of the overhead kick on this mould, and now this second thimble 40 can not move yet, thereby this product 10 is ejected to die cavity with this first thimble 30 and this runner 20 is separated, this mould continues die sinking, until this upper ejector plate 70 contacts with this spacing card 41.
Please refer to shown in Fig. 3, restriction due to this spacing card 41, make this upper ejector plate 70 drive this second thimble 40 to move to die sinking direction, this first thimble 30 and this second thimble 40 continue to move to die sinking direction simultaneously, respectively this product 10 and this runner 20 are ejected, completed the whole action that ejects.
Compared to prior art, the present invention is simple in structure, practical, saves material, ejects at twice and makes runner can not draw easily bad product, greatly improves the yield of product.
Be pointed out that, the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, all fall within the scope of protection of the present invention.
