Description

The mould of tool secondary ejecting mechanism

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of mould of tool secondary ejecting mechanism.

Background technology

In the shaping manufacture process of plastic product, if product has overhead kick, then conventional mould runs the product after taper pin or slide block all can't eject moulding, and the structure that needs to revise product this moment just can the demoulding, and this can influence the assembling effect and the outward appearance of product greatly.

Summary of the invention

In view of the above problems, the utility model provides a kind of mould of tool secondary ejecting mechanism, and is simple in structure, but its secondary eject, in conjunction with the easy elastically-deformable characteristic of plastic product, can make the smooth demoulding of plastic product of tool overhead kick.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of mould of tool secondary ejecting mechanism, can be used a push rod so that product stripping, it comprises the upper mounted plate that is fixedly connected sequentially, caster and mother module core, and the bottom plate that is fixedly connected sequentially, male model plate and male model benevolence, it is characterized in that, this mould also is movably set with fixedly connected first between this male model plate and this bottom plate, two top boards, the and the fixedly connected the 3rd, four top boards, wherein the 3rd top board is provided with a shutter, this shutter is connected in the 3rd top board and first, between two top boards, above-mentioned this push rod contacts on this second top board; In addition, this first and second roof movement is equipped with a limited post, and this limited post one end is fixed between this third and fourth top board, and the other end can contact on this male model plate; This male model benevolence and the activity of male model plate are equipped with a thimble, and this thimble is fixed between this first and second top board; Activity is equipped with a sleeve between this male model benevolence, male model plate, first top board and second top board, and this sleeve is fixed between this third and fourth top board; This bottom plate also is fixed with a fuse that can cooperate this sleeve, thimble, male model benevolence and mother module core shaped article, and this fuse is arranged in this sleeve.

So, during above-mentioned this mould matched moulds, this mother module core, male model benevolence, thimble, sleeve and fuse cooperate the plastic product of this tool overhead kick of moulding, during this mould die sinking, this mother module core is opened, this push rod rise with jack-up this first, two top boards, drive by this shutter, the 3rd, four top boards also will rise together, this moment, this thimble and this sleeve were with this product of jack-up, this product breaks away from this fuse, and when this limited post rises to when contacting on this lower bolster, this is first years old, two top boards continue to rise and break away from this shutter, the 3rd, four top boards stop to rise, this sleeve promptly stops to rise, and this product is under the thimble that continues to rise supports, and the overhead kick part of this product elastic deformation will take place to break away from this sleeve.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1, it is the mould matched moulds view of the utility model tool secondary ejecting mechanism, this mould can cooperate a push rod (not shown) so that product 500 demouldings, it comprises that a upper mounted plate 100, is fixed in caster 110, on this upper mounted plate 100 and is fixed in mother module core 120, a bottom plate 200, on this caster 110 and is fixed in male model plate 210, on this bottom plate 200 and is fixed in male model benevolence 220 on this male model plate 210, in present embodiment, this male model plate 210 connects this bottom plate 200 by cushion block 211.

This mould also is movably set with between this male model plate 210 and this bottom plate 200: one first top board 310, second top board 320 of one fixedly connected this first top board 310, one the 3rd top board 330, the 4th top board 340 of one fixedly connected the 3rd top board 330, and the 3rd top board 330 is provided with a shutter 400, this shutter 400 is connected in the 3rd top board 330 and first, two top boards 310, between 320, in present embodiment, this bottom plate 200 and the 3rd, four top boards 330,340 are provided with through hole 210,331,341, above-mentioned this push rod activity is arranged in this through hole 210,331, on 341 and contact on this second top board 320; In addition, these first and second top board 310,320 activities are equipped with a limited post 342, and these limited post 342 1 ends are fixed between this third and fourth top board 330,340, and the other end can contact on this male model plate 210; This

male model benevolence

220 and 210 activities of male model plate are equipped with a thimble 321, and this thimble 321 is fixed between this first and second top board 310,320; Activity is equipped with a sleeve 343 between this male model benevolence 220, male model plate 210, first top board 310 and second top board 320, and this sleeve 343 is fixed between this third and fourth top board 330,340; This bottom plate 200 also is fixed with a fuse 220, and this fuse 220 is arranged in this sleeve 343, and this fuse cooperates this sleeve 343, thimble 321, male model benevolence 220 and this product 500 of mother module core 120 moulding.

Please cooperate consult shown in Figure 2, when this mould die sinking, this mother module core 120 is opened, this first and second top board 310,320 of above-mentioned push rod rising jack-up, by the drive of this shutter 400, this third and fourth top board 330,340 also will rise together, and this moment, this thimble 321 and this sleeve 343 were with this product 500 of jack-up, please cooperate in addition and consult shown in Figure 3ly, this product 500 promptly breaks away from this fuse 220.

Please cooperate again consult shown in Figure 4, when this limited post 342 rises to when contacting on this lower bolster 210, this first and second top board 310,320 continues to rise and break away from this shutter 400, thereby this third and fourth top board 330,340 stops to rise, this sleeve 343 promptly stops to rise, this product 500 is under the thimble 321 that continues to rise supports, and the overhead kick part 501 of this product 500 will elastic deformation take place to break away from this sleeve 343 to these sleeve 343 centers.

In sum, the mould of the utility model, simple in structure, but secondary eject, in conjunction with the product 500 easy elastically-deformable characteristics of plastics, make the product 500 smooth demouldings of tool overhead kick part 501.
