Description
Technical field
Injection mold is the utility model is related to, more particularly to lifter demoulding mechanism in injection mold.
Background technology
After injection mold is to working of plastics injection molding, if being formed respectively with the inner and outer wall of four peripheral wall surfaces of working of plastics convex
Muscle and groove, prior art are typically first to drive the outer wall of side action sliders abjection working of plastics using oil cylinder when mould molds,
Coordinated again by oil cylinder angled-lift splits and inner core pulling sliding block, the inwall of inner core pulling sliding block abjection working of plastics is driven, finally by ejector retainner plate
By working of plastics ejection device, this is complicated, improves the development cost of mould.
The content of the invention
A kind of the shortcomings that the purpose of this utility model is to overcome prior art to exist, there is provided simple in construction, manufacturer
Just, the demoulding is smooth, reduces lifter demoulding mechanism in the injection mold of mould development cost.
The technical scheme of lifter demoulding mechanism is in the utility model injection mold：It is upper multiple including upper compound plate and lower compound plate
Die cavity is set under plate, support block is set on lower compound plate, upper ejector retainner plate, lower ejector retainner plate and thimble are set on the lower compound plate between support block,
Perforation is provided with lower compound plate, the push rod of injector is in contact with lower ejector retainner plate through perforation, core is set on support block, is set on core
Side action sliders are put, the working of plastics for having injection molding between die cavity, core and side action sliders, the inner and outer wall point of working of plastics
It is not formed with groove and convex tendon, it is characterised in that：Fixed block is set under described die cavity, and fixed block is mutually consolidated through fastener with die cavity
It is fixed, inclined guide is set in fixed block, oblique guide hole is provided with side action sliders, oblique guide hole is engaged with inclined guide, on core
Be formed with horizontal concrete chute and oblique chute, horizontal concrete chute is engaged with side action sliders bottom, on core set in slanted kicking block, interior oblique top
The side of block is engaged with the inwall of working of plastics, and the opposite side of interior slanted kicking block is engaged with oblique chute, is formed with interior slanted kicking block
Bottom chute, bottom chute are engaged with the upper end of thimble.
The utility model discloses lifter demoulding mechanism in a kind of injection mold, after working of plastics injection molding, lower compound plate
Support block, upper ejector retainner plate, lower ejector retainner plate, core, side action sliders, interior slanted kicking block and working of plastics is driven to be moved rearwards together, mould
Gradually die sinking, now inclined guide and the cooperation of the oblique guide hole of side action sliders, inclined guide drive side action sliders gradually outwards to break away
Dynamic, the bottom of side action sliders slides in and out along horizontal concrete chute, it is first deviate from the groove of working of plastics outer wall and convex tendon, instantly
When ejector retainner plate is in contact with the push rod of injector, injector push rod withstands lower ejector retainner plate and stops movement, and lower ejector retainner plate withstands top
Needle plate and thimble stop movement, and thimble withstands interior slanted kicking block and stops movement, and interior slanted kicking block withstands working of plastics and stops movement, and lower multiple
Plate, support block, core, side action sliders continue to be moved rearwards, and now the oblique chute of interior slanted kicking block and core coordinates, and core is backward
Slanted kicking block makes interior slanted kicking block gradually move inward in abjection working of plastics along the inside Slideslip of oblique chute in being driven while mobile
Groove and convex tendon on wall, while interior slanted kicking block is by working of plastics ejection device.Lifter demoulding mechanism in this programme injection mold, profit
Coordinated with inclined guide and the oblique guide hole of side action sliders, make the groove and convex tendon of side action sliders abjection working of plastics outer wall, then profit
Coordinated with the oblique chute of interior slanted kicking block and core, deviate from the groove and convex tendon of working of plastics inwall, simple in construction without oil cylinder, system
Making conveniently, reduces the development cost of mould.
