Technical field
The utility model relates to automobile injection mold field, particularly relates to a kind of secondary ejecting mechanism of automobile injection molding.
Background technology
When the demoulding of automobile injection mold, demoulding action sometimes needs Double-ejection to realize, and this is that plastic is still difficult to the complete demoulding or can not freely falls because injection mold is after once ejecting and having moved.Adopt in this case secondary ejecting mechanism, sometimes, for fear of once ejecting stressed excessive plastic distortion or damaging, improve the quality of products, injection mold also adopts secondary ejecting mechanism.
Traditional secondary ejecting mechanism, relies on spring to promote push piece plate and realizes Double-ejection, simple in structure, but spring force is not easy to control, and it is unreliable to move, and other uses splayed oscillating rod type in addition, drag hook type, jack catchs type, delayed type, lever secondary ejecting mechanism, but can make die size increase, also four of reliable mould thimbles are realized, can be the same with other structure, increase size and the complexity of mould.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of easy secondary ejection device, can reliable in action, do not increase again complexity.
A secondary ejecting mechanism for automobile injection molding, comprising: base plate, moving platen and push rod, push rod, gag lever post, front top plate, rear top board, push piece plate, angled-lift splits, guide rail, limit frame, spring and comprise will by product release core.
On described moving platen, mavable module core is installed, is connected with angled-lift splits on base plate, angled-lift splits is fixed constraints frame around, and the effect of limit frame is to make slide block along guide rail horizontal movement, and angled-lift splits is fixed on guide rail, can be along guide rail horizontal movement.
Angled-lift splits and rear top board level connection joint, rear top board and front top plate level connection joint, push rod runs through rear top board, front top plate, one end is connected with rear top board, the other end is fixed on push piece plate, coupling hook between push piece plate and push rod, and push rod one end is connected on front top plate, the other end is connected on core, between front top plate and moving platen, be connected with gag lever post, between gag lever post and front top plate, be provided with Compress Spring, described core arranged outside has anti-rotation block simultaneously.
When after plastic injection-moulded completing, while carrying out the demoulding, mobile angled-lift splits, thereby connecting rear top board, front top plate travels forward together, and push rod heads on core, thereby product is deviate from from core, and push rod is realized and being ejected for the first time, continues to move forward taper slide, push rod, under the promotion of rear top board, drives moving platen to realize the goods that eject for the second time in core, like this, realize and ejecting for the second time, the complete demoulding of product like this, then matched moulds, carries out next cycle injection moulding.
The length of gag lever post can be reconciled, and the effect of Compress Spring is also in order to reconcile the pressure between gag lever post and front top plate, and described core outside is also provided with anti-rotation block.
A kind of optimal technical scheme, what described demoulding transmission mechanism pressure used adopted is the hydraulic cylinder kind of drive.
A kind of optimal technical scheme, the secondary ejecting mechanism of described a kind of automobile injection molding, be provided with resetting-mechanism, in the time that mould is closed, each of ejection system ejects element and returns to the position of original setting, a kind of optimal technical scheme, at front top plate and push piece plate, between rear top board and push piece plate, be provided with back-moving spring.
The utility model is simple in structure, and reliable in action can ensure the demoulding quality of mould product.
