Mould angle pin ejection mechanism overall schematic.
The ejection mechanism for female die oblique pin of the present invention, applied in mould, the mould has caster 101, mother module core
103, male template 102, male die core 104, upper mounted plate 106, stripper plate 105, shutter A107, the ejection mechanism for female die oblique pin bag
Include：
Blind thimble board slot 301, is arranged at the front of caster 101,103 back side of mother module core；
Ejector retainner plate 302, is arranged in blind thimble board slot 301, is left in groove and exit back-off surplus；
Oblique pin base 202, is arranged on the ejector retainner plate 302 in blind thimble board slot 301；
Mother plate inclined pin 201, is arranged in the mother module core 103 of mould, and one end of the mother plate inclined pin 201 is movably arranged at oblique pin base
In 202；
Shutter B500, the shutter B500 include：
Gum cover 503, is arranged in male die core 104；
Adjusting screw 502, is arranged in mother module core 103；
Ejector retainner plate pull rod 501, is arranged in mother module core 103, and the ejector retainner plate 302 in blind thimble board slot 301 is fixed in one end
On, the other end is fastened with adjusting screw 502.
Wherein, have in the blind thimble board slot 301 and an only ejector retainner plate 302.
Wherein, blind 301 back side of thimble board slot is equipped with an auxiliary ejection element 303.
Wherein, the auxiliary ejection element 303 is a spring.
Refer to shown in Fig. 3 and Fig. 4, Fig. 3 depicts ejection mechanism for female die oblique pin molding state partial schematic diagram, and Fig. 4 is painted
Ejection mechanism for female die oblique pin die opening state partial schematic diagram is shown.
During mould die sinking, stripper plate 105 is separated with caster 101, after upper mounted plate is separated with stripper plate 105,
Male and female template molds.Caster 101, mother module core 103 and mother plate inclined pin 201 are molded upwards, the positioning tie bar in shutter A
And gum cover is pulled upwardly therewith, surplus that the ejector retainner plate 302 during die sinking in blind thimble board slot 301 is set by shutter B500
Do not cover, remained stationary as under the action of ejector retainner plate pull rod.Because of the taper pin on positioning plate 302 when mother plate inclined pin 201 molds upwards
Seat is motionless and is inwardly moved along the groove in oblique pin base 202.Caster 101, mother module core 103 and mother plate inclined pin 201 continue up into
Row die sinking, the surplus in blind thimble board slot 301 can be less and less, mother plate inclined pin 201 along 202 groove of oblique pin base stroke also increasingly
Small, auxiliary ejection element 303 can also be ejected because the surplus at 302 back side of ejector retainner plate is increasing, and auxiliary ejector retainner plate 302 is applied downwards
Add aux. pressure.When mother module core 103, caster 101 and mother plate inclined pin 201 are molded the surplus in blind thimble board slot 301 upwards
When covering, mother plate inclined pin 201 terminates in the stroke in 202 groove of oblique pin base, completes mother plate inclined pin 201 and exits 10 back-off face 11 of product
Action.Auxiliary ejection element 303 is also fully extended, and the surplus that shutter B500 is set also is covered, ejector retainner plate 302 at this time and mother
Mode 103 relies closely.Caster 101, mother module core 103 and mother plate inclined pin 201 continue to mold the setting of shutter B500 at this time
Surplus is covered, and is continued die sinking and is driven the ejector retainner plate 302 in blind thimble board slot 301 to mold upwards.Because of the ejector retainner plate of shutter B500
Pull rod 501 is fixed on ejector retainner plate 302, and die sinking upwards makes the gum cover 503 of shutter B500 depart from adjusting screw 502.So far
Ejection mechanism for female die oblique pin die sinking action is completed, when between the gum cover of the shutter A107 in caster 101 and adjusting screw points
From when, male template 102 and caster 101 are completed to separate, and male die core 104 is separated with the completion of mother module core 103.When separation to product 10
After ejecting preset value, product 10 will be ejected by die ejection system, complete whole mould die sinking, 10 ejection of product action.
When mold clamping, 10 ejection system elder generation return of product, the molding of male and female template.Caster 101 and mother module core 103 to
While lower return, the ejector retainner plate 302 in blind thimble board slot 301 does not do returning movement, corresponding mother plate inclined pin 201 and oblique pin base
202 also do not take exercises.During caster 101 and mother module core 103 continue return, the gum cover 503 of shutter B500 is with adjusting
Nut merges and covers setting value, and ejector retainner plate pull rod 501 at this time can push up ejector retainner plate 302 to the blind top of thimble board slot 301, and
By 303 return of auxiliary ejection element.And mother plate inclined pin 201 ejector retainner plate pull rod 501 eject ejector retainner plate 302 after in male die core 104
Amalgamation power under can be moved out along 202 groove of oblique pin base, be repositioned at 10 back-off face 11 of product.Mother plate inclined pin ejects this moment
Mechanism completes revert action.When the gum cover in shutter A107 and adjusting screw surplus are covered, when being completely integrated, caster 101
Close and close with male template 102, mother module core 103 is closed with male die core 104 and closed.Then stripper plate 105 merges with caster 101, upper fixation
Plate 106 merges with stripper plate 105, and mould molds completely.Mould completes mould assembling action, waits injection molding machine to be injected, under starting
One cycle operation.
In conclusion the ejection mechanism for female die oblique pin of the present invention, by processing a blind thimble board slot at 103 back side of mother module core
301, one piece of ejector retainner plate 302 is only done in groove.Oblique pin base 202 is fixed on and is determined on needle plate 302,201 one end of mother plate inclined pin is active in
In 202 groove of oblique pin base.A shutter B500 is assembled, drives ejector retainner plate 302 to move downward by shutter B500 and pull rod, blind
An auxiliary ejection element 303 auxiliary ejector retainner plate 302 is equipped with thimble board slot 301 to eject, when ejector retainner plate 302 encounters mother module core 103,
Stop motion.Continue to mold, mother plate inclined pin 201 exits product back-off face 11 along 202 groove of oblique pin base.This structure makes mother plate inclined pin
201 convenience, rapidly exit back-off, shorten perpendicular flow channel length, are conducive to runner pull-out, while reduce mold thickness, save mould
Have material cost, meet the needs of actual production.
