Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail with specific embodiment：As shown in Figures 1 to 4, one
The injection mold with sliding block core-pulling mechanism, including upper bolster 2 and die shoe 1 are planted, the upper bolster 2 is provided with die 26, institute
State die shoe 1 and be provided with punch 3, sliding between the upper bolster 2 and die shoe 1 is provided with the first ejector half core 4, the upper bolster
2 are provided with the first support member 21 and the second support member 22, and the first ejector half core 4 is connected with screw rod 41, and the screw rod 41 is passed through
The support member 22 of first support member 21 and second, is arranged with gear 23 and the gear 23 is located at described first on the screw rod 41
Between the support member 22 of support member 21 and second, the side wall of the upper bolster 2 is provided with tooth bar bearing 11, and the tooth bar bearing 11 is arranged
There is tooth bar 12, the tooth bar 12 coordinates the gear 23 to be engaged work, and the punch 3 is interior to be provided with mandrel cavity 31, described
Two the second ejector half cores 5 are provided with mandrel cavity 31, connecting spring 32 and the spring 32 retraction general between the second ejector half core 5
Two the second ejector half cores 5 are adjacent to each other, and permanent magnet 52 is provided with the second ejector half core 5, set on the inwall of the mandrel cavity 31
Being equipped with after energization can attract the close electromagnet 33 of the permanent magnet 52.
The upper bolster 2 is provided with chute 25, and on the first ejector half core 4 lead column 42, the lead column 42 are provided with
The activity in the chute 25.So arrange so that the track that the first ejector half core 4 can be set according to chute 25 is moved, will not
The predetermined track of skew, so as to avoid damaging device.
Second support member 22 is provided with ball 221, first support member 21 towards on the side wall of the gear 23
On be also equipped with ball.The effect of ball is exactly to reduce frictional force, when rotate under drive of the gear 23 in tooth bar 12 when
Wait, it may contact with the second support member 22 or the first support member 21, if without ball 221, rubbing between them
It is exactly sliding friction to wipe power, and this will damage gear 23, the second support member 22 or the first support member 21.And it is provided with ball
221, it becomes possible to which sliding friction is changed into into rolling friction, frictional force so greatly reduces.Also, by design, can make
Obtain ball 221 to be first depleted, so as to protect gear 23, the second support member 22 and the first support member 21.
The upper wall of the mandrel cavity 31 and gathering sill 311 is provided with going to the bottom, the second ejector half core 5 is provided with guide head
53, the guide head 53 moves the movement to the second ejector half core 5 in the gathering sill 311 and is oriented to.So arrange so that
Second ejector half core 5 can will not offset predetermined track according to the track movement set, so as to avoid damaging device.And, will
Motion track is defined, and facilitates spring 32 and permanent magnet 52 to be operated.
This device first wants matched moulds, namely die shoe 1 to move up near upper bolster 2 before injection work is carried out.This just makes
The also upper shifting of tooth bar bearing 11 is obtained, so that tooth bar 12 is rotated with moving gear 23.Gear 23 is by the second support member 22 and first
Support member 21 limits movement, so when it rotates, because the relation of threaded connection, will cause screw rod 41 to occur
It is traversing, such that driving the first ejector half core 4 to move in the case where the track of chute 25 limits, move towards its operating position
It is dynamic.Meanwhile, electromagnet 33 is energized generation magnetic field force, attracts permanent magnet 52 close.This magnetic field force is better than the elastic force of spring 32,
Thus allow the second ejector half core 5 to be moved, reach its operating position.Now, this device completes preparation, can carry out
Inject.The cylinder protuberance 51 of the second ejector half core 5 can act on plastic melt 6 so that the medial surface of product forms surrounding
The side recess feature of closing.Together, the product for allowing for producing includes four with side for first ejector half core 4 and the second ejector half core 5
There is side recess feature simultaneously in week closing, both sides.
This device injects plastic melt 6 after assembling from injection port 24, carries out injection mo(u)lding work.
After completing to be molded work, upper bolster 2 and die shoe 1 are away from one another, and die shoe 1 is moved down, and this is just for this device
So that tooth bar bearing 11 is also moved down, so that tooth bar 12 is rotated with moving gear 23.Gear 23 is by the second support member 22 and first
Support member 21 limits movement, so when it rotates, because the relation of threaded connection, will cause screw rod 41
Life is traversing, such that driving the first ejector half core 4 to move in the case where the track of chute 25 limits.
After completing to be molded work, the second internal ejector half core 5 is also required to depart from operating position this device.Now, disconnect
The electricity of electromagnet 33 so as to magnetic force cannot be produced and attract permanent magnet 52.Therefore, the second ejector half core 5 is acted in the elastic force of spring 32
Under, bounce back to original position.After the first ejector half core 4 and the second ejector half core 5 depart from operating position, it becomes possible to by injection mo(u)lding
Product is taken out.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
It is defined, any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement each fall within the present invention's
Protection domain.
A kind of injection mold with sliding block core-pulling mechanism of the present invention, using simple dexterously pulled core structure, substitutes existing
The structure of some Angle Pin formulas, so as to reduce production difficulty, and can produce with side include all round closure, two
The product of the recessed feature of avris.
