Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Below in conjunction with accompanying drawing, the technical solution of the utility model is clearly and completely described, it is clear that described embodiment is a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.In description of the present utility model, it should be noted that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "left", "right", " vertically ", " level ", " interior ", " outward " be based on orientation shown in the drawings or position relationship; be for only for ease of description this utility model and simplifying and describe; rather than instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Refer to Fig. 1 and Fig. 2, a kind of mechanical type time-delay mechanism, being installed on drawing and moulding mould, described drawing and moulding mould includes mould (not shown) and the counterdie (not shown) matched with upper mould, and described counterdie is provided with blank holder movable up and down.Described mechanical type time-delay mechanism includes crossbeam 1, is installed in the support bar 2 at crossbeam 1 two ends, fixed block 3, contiguous block 4, rotating seat 5, push rod 6 and elastic component 7.Described crossbeam 1 is movably arranged on mould on the eccentric swage 8 of setting.Described fixed block 3 is fixed on described counterdie, and described rotating seat 5 is fixed in described blank holder (not shown).The upper end of described contiguous block 4 is resisted against the lower end of support bar 2, and the lower end of contiguous block 4 is installed on described rotating seat 5, and described push rod 6 is fixed on described contiguous block 4.Described elastic component 7 one end is fixed on push rod 6, and the other end is resisted against on described blank holder.
In the present embodiment, described crossbeam 1 is movably arranged on described eccentric swage 8, and crossbeam 1 and the stroke distances being told a mould eccentric swage 8 apart.
Specifically, described fixed block 3 is fixed on described counterdie, and is positioned at the both sides of described blank holder.
It is provided with two projections 31 inside described fixed block 3 upper end, stopper slot is formed between two projections 31, on described contiguous block 4, correspondence is convexly equipped with limited block 41, described limited block 41 is installed in the stopper slot of fixed block 3, when described drawing and moulding mould is in matched moulds state, the design of above-mentioned position limiting structure can effectively control the position of described contiguous block 4.
In the present embodiment, described elastic component 7 is spring.
This utility model mechanical type time-delay mechanism operation principle: when described drawing and moulding mould die sinking, described upper mould moves upward under external force, described blank holder upwardly described crossbeam 1, support bar 2, contiguous block 4, rotating seat 5 and eccentric swage 8 move upward, and the limited block 41 of described contiguous block 4 is away from the stopper slot of described fixed block 3.When moving to the stroke distances of described blank holder, described elastic component 7 pushes out to described contiguous block 4 by discharging elastic potential energy and rotates for the point of rotation with described rotating seat 5.Now, described contiguous block 4 and described support bar 2 depart from, described crossbeam 1, support bar 2 and eccentric swage 8 move downward, described upper mould continues up, move upward with described upper mould after the stroke distances of crossbeam 1, strut 2 and eccentric swage 8 motion certain distance, and then achieve the mechanical type time delay in die sinking process by this utility model mechanical type time-delay mechanism.When described drawing and moulding mould matched moulds, the dynamic described crossbeam 1 of upper modular belt, strut 2 and eccentric swage 8 move downward, owing to described crossbeam 1 is movably arranged on described eccentric swage 8, and crossbeam 1 and the stroke distances being told a mould eccentric swage 8 apart, therefore described eccentric swage 8 first contacts with the product installed on described counterdie 2, ensure that product local when molding pushes down forming surface effectively, solve the problem that product is wrinkling.Then described upper mould promotes described crossbeam 1, support bar 2, eccentric swage 8 and blank holder to continue to move downward, when described blank holder moves to the stopper slot place of described fixed block 3, described limited block 41 is installed in the stopper slot of fixed block 3, now, the lower end of described support bar 2 and contiguous block 4 upper-end contact, it is achieved thereby that the mechanical type time delay in drawing and moulding mould matched moulds process.
In sum, this utility model mechanical type time-delay mechanism is installed on drawing and moulding mould, by structural design of the present utility model, in die sinking and matched moulds process, achieve the mechanical type time delay of drawing and moulding mould, solve the problem that in matched moulds process, product is wrinkling simultaneously, improve the stability of product, reduce production cost.
