Description
Technical field
The present invention relates to injection mold, more particularly to injection mold worm and gear secondary core-pulling mechanism.
Background technology
At present, the tapped injection mold of tank product in industry, generally drives spiral shell using external power oil motor
Rasp bar rotates out the internal thread hole of product, but the reason for be due to unstability and the rotating speed bad control of oil motor, to mould
The long-term stable mass production of tool easily causes unexpected abnormality, while the extra oil circuit connection requirement of oil motor is, it is necessary to mould
After die sinking is stable, injection machine equipment could provide oil pressure action to oil motor, so result in the molding cycle of mould production
It can lengthen, reduce the production efficiency of mould.
The content of the invention
The invention aims to overcome the shortcoming that prior art is present, there is provided drive screw thread to take out while one kind die sinking
Core bar rotates out the internal thread hole of product, having stable behavior, reliable, and energy consumption is low, improves production efficiency, reduces the note of production cost
Mould worm and gear secondary core-pulling mechanism.
The technical scheme of injection mold worm and gear secondary core-pulling mechanism of the present invention is：Including die cavity and core, in die cavity
Core insert is set in middle setting cavity block, core, there is the working of plastics of injection molding between cavity block and core insert,
The side of working of plastics, which is formed with screwed pipe, screwed pipe, screwed hole, it is characterised in that：Gag lever post is set under described die cavity and oblique
Guide pillar, sets between inner slide and outer slide, inner and outer slider on core and sets fixed plate, fixed plate is through fastener and interior cunning
Block is mutually fixed, and spacing hole is provided with inner slide, and spacing hole is engaged with gag lever post, sets little gear, screw thread to take out in inner slide
Core bar, bearing and gear wheel, little gear are meshed with screw thread core pulling bar, gear wheel, the screwed hole of screw thread core pulling bar and working of plastics
It is engaged, worm gear is set in bearing and gear wheel, oblique guide hole and positioning hole are provided with outer slide, oblique guide hole matches with Angle Pin
Close, spacing blind rivet be set in positioning hole, one of spacing blind rivet mutually fixes through positioning hole with fixed plate, spacing blind rivet it is another
Head is engaged with positioning hole, and worm screw is set in outer slide, and one of worm screw passes through outer slide, fixed plate and inner slide and worm gear
It is engaged.
The invention discloses a kind of injection mold worm and gear secondary core-pulling mechanism, after working of plastics injection molding, core,
Core insert, inner slide, outer slide, fixed plate, little gear, screw thread core pulling bar, bearing, gear wheel, worm gear, spacing blind rivet, snail
Bar and working of plastics are moved rearwards by together, now with the Angle Pin of die cavity and the oblique guide hole of outer slide, and Angle Pin drives outer sliding
Block is gradually moved laterally, and outer slide drives worm screw to move laterally simultaneously, and worm and wheel is engaged, when worm screw is moved out
Worm gear rotation is driven when dynamic, worm gear drives gear wheel rotation, and rotation that the large gear turn the small gear, little gear drives screw thread core pulling bar
Rotation, makes screw thread core pulling bar gradually rotate out the screwed hole of working of plastics, realizes first time screw thread core pulling；And now due to die cavity
On gag lever post and inner slide spacing hole coordinate, inner slide is not outward driven by outer slide, when mould gradually mold to
When spacing blind rivet on gag lever post abjection spacing hole, and fixed plate is in contact with the positioning hole in outer slide, now Angle Pin is passed through
Oblique guide hole continues to drive outer slide to move outward, and outer slide pulls fixed plate to move outward together through spacing blind rivet, fixed plate band
Dynamic inner slide, little gear, screw thread core pulling bar, bearing, gear wheel, worm gear are moved outward together, make screw thread core pulling bar completely out
The screwed pipe of working of plastics, realizes second of vertical pulling core pulling, after screw thread core pulling bar deviates from screwed pipe, can eject working of plastics de-
Mould.Side action sliders are divided into outer slide and inner slide, opened in mould by this programme injection mold worm and gear secondary core-pulling mechanism
Mould is first displaced outwardly using outer slide simultaneously, the worm gear in worm screw and inner slide on outer slide, then by worm gear and canine tooth
Drive screw thread core pulling bar to complete first time screw thread core pulling after wheel, pinion fits speed change, recycle spacing blind rivet and positioning hole to match somebody with somebody
Close, drive inner slide and screw thread core pulling bar to be displaced outwardly, complete secondary vertical pulling core pulling, save existing oil motor structure, tie
Structure is simpler, reduces manufacturing cost, having stable behavior, reliable, and rotating speed is easily controlled, and energy consumption is low, improves production efficiency, reduction life
Produce cost.
It is provided with injection mold worm and gear secondary core-pulling mechanism of the present invention, described inner slide, outer slide and fixed plate
Spring is set in the spring eye communicated, spring eye, guide rod is set in the spring, one of spring is in contact with inner slide, spring
Other end be in contact with outer slide.When Angle Pin and oblique guide hole, which coordinate, drives outer slide to slide in and out, spring is in restoring force
Also outer slide is promoted to slide outward under effect, Angle Pin combination spring, making outer slide, sliding action is more stablized, reliably outward.
