The novel secondary ejecting mechanism
[technical field]
The utility model relates to a kind of mould structure, is specifically related to a kind of secondary ejecting mechanism.
[background technology]
When producing plastic cement products, especially for the shell series products, its moulding major part is at master mold.When the mould die sinking, generally adopt a master mold glue degree of lip-rounding formula of hiding to advance 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, being 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 when expecting to save simultaneously two liftout plates.
[utility model content]
In order to achieve the above object, the utility model provides a kind of novel secondary ejecting mechanism, it is applied in the 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, one end penetrate this male model plate, and the other end of this first thimble is located in this upper ejector plate;
The second thimble, one end penetrate this male model plate, and the other end of this second thimble penetrates this upper ejector plate and this time liftout plate contacts with this bottom plate when matched moulds;
Spacing card, it is snapped on this second thimble.
Better, described spacing card and described the second thimble interference fits.
During this mould matched moulds, an end of this first thimble passes this male model plate and this male die core and stretches into and be used for ejecting product in the die cavity, and an end of this second thimble passes this male model plate and this male die core is used for ejecting runner.
During this mould die sinking, this caster and this male model plate are separately, this upper ejector plate and this time liftout plate drive this first thimble and move to the die sinking direction, this moment, this second thimble was failure to actuate, thereby this first thimble breaks away from this product and this runner, this mould continues die sinking, until this upper ejector plate contacts with this spacing card, because the restriction of this spacing card, this first thimble and this second thimble continue to move to the die sinking direction simultaneously, respectively this product and this runner are ejected, finished the whole action that ejects.
Compared to prior art, the utility model is simple in structure, and is practical, and economical with materials ejects at twice and makes runner can not draw easily bad product, has greatly improved product yield.

[specific embodiment]
The below is described in further detail preferred embodiments of the present utility model by reference to the accompanying drawings.
Please refer to shown in Figure 1, the utility model provides a kind of novel secondary ejecting mechanism, it is applied in the 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, one end penetrate 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, one end penetrate this male model plate 60, and the other end of this second thimble 40 penetrates this upper ejector plate 70 and this time liftout plate 80 contacts with this bottom plate 90 when matched moulds;
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, an end of this first thimble 30 passes this male model plate 60 and this male die core 61 and stretches into and be used for ejecting product 10 in the die cavity, and an end of this second thimble 40 passes this male model plate 60 and this male die core 61 is used for ejecting runner 20.
Please refer to shown in Figure 2, during this mould die sinking, this caster 50 and this male model plate 60 are separately, this upper ejector plate 70 and this time liftout plate 80 drive this first thimble 30 and move to the die sinking direction, this runner 20 can't move because of the overhead kick on this mould, and this moment, this second thimble 40 can not move yet, thereby this product 10 is ejected 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 Figure 3, because the restriction of this spacing card 41, so that driving this second thimble 40, this upper ejector plate 70 moves to the die sinking direction, this first thimble 30 and this second thimble 40 continue to move to the die sinking direction simultaneously, respectively this product 10 and this runner 20 are ejected, finished the whole action that ejects.
Compared to prior art, the utility model is simple in structure, and is practical, and economical with materials ejects at twice and makes runner can not draw easily bad product, greatly improves the yield of product.
Be pointed out that; the utility model is not limited 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 solutions of the utility model all fall in the protection domain of the present utility model.
