Description
Technical field
The present invention relates to injection mold technologies, relate in particular to a kind of secondary ejection mold.
Background technology
In the design of injection mold, the product equipped with more button bits can be frequently encountered, it is common practice to oblique top or pendulum
Bar allows certain elastic deformation space come forced stripper mechanism using the characteristic combination product structure of material, but for some products
These schemes are simultaneously not suitable for, such as a product is not very big, but oblique top is arranged in multiple button bits of arranging, not enough positions,
And be not suitable for forced stripper mechanism, i.e., existing technology can not be used to realize demoulding, prior art demoulding in addition is lacked there is also following
Point：
1, existing ramp-roof structure, because the sliding seat of oblique top is easy to wear, in addition reasons in structure, when injection molding, cannot protect
Extraordinary vertical support is demonstrate,proved, it is easy to appear relatively low or higher phenomenons, relatively low more glue to influence for oblique top when causing to produce
Assembling product, when higher dropout, may shovel injured labour product,
What 2, existing ramp-roof structure cannot be done is too small, otherwise easy to produce elastic deformation cause product quality unqualified and
The case where being broken, if by ramp-roof structure design it is big a bit, influence whether the design of inner mould core fortune water.
3, existing ramp-roof structure demoulding meeting product is not easy to fall.It needs artificial or manipulator to grab, that is, can not achieve
Automatic demoulding.
4, existing ramp-roof structure needs processing inclined and irregular part, processing cost higher.
Invention content,
To solve above-mentioned technical problem of the existing technology, the present invention provides a kind of secondary ejection mold, by secondary
Ejecting structure is realized will not damage product surface while product smoothly demoulds, and in addition also not need and increase outside the design of oblique top
Size transports the design of water to influence inner mould core, furthermore automatic demoulding may be implemented.
The technical solution adopted by the present invention is：A kind of secondary ejection mold is provided, secondary ejecting mechanism is equipped with, it is described secondary
Ejecting mechanism includes bottom plate, the support column on bottom plate, the dynamic model block being fixed on support column, and the support column sliding is equipped with
First top plate, the second top plate and third top plate, the dynamic model block are equipped with limit pull rod.
The third top plate is fixed with ejection fixed block.
First top plate and the second top plate are fixedly connected, and disengaging machine is equipped between first top plate and the second top plate
Structure.
The releasing mechanism includes the locating piece being set between the first top plate and the second top plate and slides company with locating piece
The position limiting slide block connect.
First top plate is equipped with fourth lane, and the locating piece lower part is equipped with third channel, and the locating piece top is set
There are second channel, second top plate to be equipped with first passage, the first passage, second channel, third channel and fourth lane
Coaxially.
The right side of the limit sliding shoe is equipped with the first spring, and the first inclined-plane is equipped on the left of the limit sliding shoe, described
It ejects fixed block and is equipped with screens slot, the screens slot is equipped with the second inclined-plane with the cooperation sliding of the first inclined-plane.
The limit pull rod is equipped with third inclined-plane, and Five-channel, the limit sliding are equipped in the middle part of the limit sliding shoe
The 4th inclined-plane with the cooperation sliding of third inclined-plane is equipped in the middle part of block.
Operation principle：The first top plate, the second top plate and third top plate move together when beginning, are inserted when moving to limit pull rod
By the effect on third inclined-plane and the 4th inclined-plane when entering to limit sliding shoe, limit sliding shoe is made to move right to realize that substep is de-
From.
Using the above structure, it is same to realize that product smoothly demoulds by secondary ejection structure compared with prior art by the present invention
Shi Buhui damages product surface, does not in addition also need and increases the design size of oblique top outside and transport setting for water to influence inner mould core
Meter, furthermore automatic demoulding may be implemented.
