Abstract
The invention provides a plastic mould secondary ejection mechanism. The mechanism comprises two upper ejection plates, two lower ejection plates and a foot pad, wherein the end edge of one upper ejection plate is provided with a square poking block groove in which a square poking block is arranged; the end edge of one lower ejection plate is provided with an allowance part; and a limiting groove is arranged on the inner side of the foot pad. By increasing one upper ejection plate, one lower ejection plate and one poking block, the secondary ejection of the mould ejection mechanism is realized; the mechanism has a simple structure and moves stably; one ejection stroke of the ejection mechanism is divided into two ejection strokes; the single ejection stroke is smaller; and the phenomenon that the finished product is clamped after a flat ejector pin is ejected, so the finished product cannot freely fall off and is even difficult to fetch with hand is avoided.
Description
Technical field
The present invention relates to the plastic mould ejecting mechanism, specifically a kind of plastic mould secondary ejecting mechanism.
Background technology
In the plastic mould manufacturing industry, ejecting mechanism is the indispensable part of plastic mould, during the design plastic mould, other liftout components such as dome pin, flat thimble, sleeve all need be set in ejecting mechanism help finished product disengaging mould.
When the rib of plastic cement finished product is a lot, when not having enough spatial arrangement dome pins in the die, the more flat thimble pushing-off product of just need arranging.After being provided with flat thimble in the ejecting mechanism, the body of more plastic rib one classes of its head because flat thimble is square, so be easy to take place flat thimble locking product, make the finished product hand that can not freely come off even get difficult phenomenon, cause the damage of mould and the interruption of production.How that avoids taking place similar phenomenon in the mould of flat thimble of having arranged, be the industry problem demanding prompt solution always.
Summary of the invention
Because above-mentioned problem, the finished product hand that can not freely come off even takes place the plastic mould of the flat thimble of having arranged easily gets difficult phenomenon, the objective of the invention is to overcome the deficiencies in the prior art and defective, and a kind of plastic mould secondary ejecting mechanism is provided.
The invention provides a kind of plastic mould secondary ejecting mechanism, comprise upper ejector plate, following liftout plate, foot pad.This upper ejector plate has two, and wherein a upper ejector plate end limit is provided with square slide block groove, is provided with square slide block in this groove; This time liftout plate has two, and wherein a following liftout plate end limit is provided with clearance position; This foot pad inboard is provided with stopper slot.
More excellent, described slide block is arranged in the slide block groove on upper ejector plate end limit by the connected mode of hinge.
Compared with prior art, the present invention realizes that with the mode that increases a upper ejector plate, a following liftout plate and a slide block secondary of mould ejecting mechanism ejects, it is simple in structure, mechanism kinematic is stable, ejecting mechanism ejection stroke once is divided into twice, and the finished product hand that can not freely come off is even got difficult phenomenon.
Description of drawings
Fig. 1 is the structural representation of a kind of plastic mould secondary ejecting mechanism of the present invention.
Fig. 2 ejects the action schematic diagram first time of a kind of plastic mould secondary ejecting mechanism of the present invention.
Fig. 3 ejects the action schematic diagram second time of a kind of plastic mould secondary ejecting mechanism of the present invention.
The specific embodiment
For describing technology contents of the present invention, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 1, be the structural representation of a kind of plastic mould secondary ejecting mechanism of the present invention.Upper ejector plate has two, be respectively 1 and 3, wherein offer square slide block groove 9 on the upper ejector plate 3 end limits, be provided with square slide block 5 in this slide block groove 9, slide block 5 is arranged in the slide block groove 9 by hinge 6, and hinge 6 is madial wall and all very smooth sleeve pipe of lateral wall, and coefficient of friction is very little, slide block 5 adopts the connected mode of hinge 6, can make the more smooth and easy of slide block 5 rotations.Following liftout plate has two, is respectively 2 and 4, wherein descends liftout plate 4 end limits to be provided with clearance position 10, when the rotation of slide block 5, for it provides enough spaces.Foot pad 7 inboards are provided with stopper slot 8.
Please continue to consult Fig. 2, for ejecting for the first time of a kind of plastic mould secondary ejecting mechanism of the present invention the action schematic diagram.When die sinking, ejecting mechanism up moves, and four liftout plates 1,2,3,4 drive flat thimble 11 and 12 and eject product 13, up to finishing ejection stroke for the first time.
Please continue to consult Fig. 3, for ejecting for the second time of a kind of plastic mould secondary ejecting mechanism of the present invention the action schematic diagram.After the first time, ejection stroke was finished, the slide block 5 that is arranged on the upper ejector plate 3 end limits moves to the top that is limited to groove 10, ejecting mechanism continues to move upward, stopper slot 8 tangles an end of slide block 5, it is rotated, an end that tangles is rotated down and the other end rotates up and contact under liftout plate 2, upper ejector plate 1 and following liftout plate 2 also move upward under the effect of this power that makes progress thereupon, drive flat thimble 12 and continue to eject product 13, eject fully up to product 13.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by the scope of claims of the present invention.
