Nail, worm screw and working of plastics are moved rearwards together, and now with the Angle Pin of die cavity and the oblique guide hole of outer slide, Angle Pin drives
Outer slide gradually moves laterally, and simultaneously outer slide drive worm screw move laterally, worm and wheel is engaged, when worm screw to
Worm gear rotation is driven when outer mobile, worm gear drives gear wheel rotation, and rotation that the large gear turn the small gear, little gear drives screw thread to take out
Core bar rotates, and screw thread core pulling bar is gradually rotated out the screwed hole of working of plastics, realizes first time screw thread core pulling；And now due to
The spacing hole of gag lever post and inner slide on die cavity coordinates, and inner slide is not driven outward by outer slide, when mould is gradually opened
Mould to gag lever post deviates from spacing hole, and when the spacing blind rivet in fixed plate is in contact with the positioning hole in outer slide, now tiltedly leads
Post continues to drive outer slide to move outward through oblique guide hole, and outer slide pulls fixed plate to move outward together through spacing blind rivet, fixed
Strip is moved inner slide, little gear, screw thread core pulling bar, bearing, gear wheel, worm gear and moved outward together, makes screw thread core pulling bar complete
Deviate from the screwed pipe of working of plastics, realize second of vertical pulling core pulling, after screw thread core pulling bar deviates from screwed pipe, working of plastics can be ejected
The demoulding.Side action sliders are divided into outer slide and inner slide, in mould by this programme injection mold worm and gear secondary core-pulling mechanism
Die sinking 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 greatly
Drive screw thread core pulling bar to complete first time screw thread core pulling after gear, pinion fits speed change, recycle spacing blind rivet and positioning hole
Coordinate, drive inner slide and screw thread core pulling bar to be displaced outwardly, complete secondary vertical pulling core pulling, save existing oil motor structure,
Structure is simpler, reduces manufacturing cost, having stable behavior, reliable, and rotating speed is easily controlled, and energy consumption is low, improves production efficiency, is reduced
Production cost.
The utility model injection mold worm and gear secondary core-pulling mechanism, in described inner slide, outer slide and fixed plate
The spring eye communicated is provided with, spring is set in spring eye, guide rod is set in the spring, one of spring is in contact with inner slide,
The other end of spring is in contact with outer slide.When Angle Pin and oblique guide hole, which coordinate, drives outer slide to slide in and out, spring is returning
Also promote outer slide to slide outward under multiple power effect, Angle Pin combination spring, make outer slide outward sliding action more stablize, can
Lean on.
