The female thread inner screw sheath rotates while axially outwardly moving, and makes external screw thread fuse outwards deviate from the female thread of working of plastics
Hole, and lower compound plate drives dynamic model installing plate, mould foot, upper ejector retainner plate, lower ejector retainner plate, ejector sleeve fuse, ejector sleeve, dynamic model and working of plastics to continue
Continue and be moved rearwards by, when the oblique surface of tongue lower end, cover half side contacts with the public drag hook of twice-die-opening public affairs block, public drag hook warp
Oblique surface inwardly promotes tongue, makes in tongue retraction spring groove, thus causes tongue also to disengage with female drag hook, now mould
Gradually open at dynamic model and cover half, mould secondary die sinking, finally driven ejector sleeve to be ejected by working of plastics de-by upper and lower ejector retainner plate
Mould.Eight inner threaded core-pulling mechanisms of this programme injection mold screw thread tooth bar formula, utilize tooth bar and the cooperation of external screw thread fuse,
External screw thread fuse coordinates with inner screw sheath, in conjunction with twice-die-opening public affairs block, twice-die-opening mother tuber and the cooperation of tongue, makes mould
First open between tooth bar fixed plate and cover half, external screw thread fuse rotary core pulling, then make mould from die sinking between dynamic model and cover half,
By working of plastics automatic ejection demoulding, and without workman, working of plastics and inserts taking-up are put in fixture again and loose core, thus the side of operation
Just, alleviate the labor intensity of workman, improve production efficiency.
Eight inner threaded core-pulling mechanisms of this utility model injection mold screw thread tooth bar formula, described ejector sleeve fuse top
Outer wall has pass hopper, and the inwall of pass hopper is for tiltedly to close charge level, and an outer wall of screw thread fuse is shaped with corresponding inclined-plane outside,
One of external screw thread fuse matches through working of plastics with the pass hopper of ejector sleeve fuse.Owing to the motion of external screw thread fuse should be held
By rotary motion radially, moving before and after also bearing axially, its action is the most complicated, so necessarily requiring in injection
Period is the most firm, and of external screw thread fuse is coordinated with the charge level that tiltedly closes closing hopper by inclined-plane so that close material sealing position more
Accurately.The other end of described external screw thread fuse is round table surface, and round table surface matches with the inclined-plane of lock module inwall.Make matched moulds locked mode
During block reset, the inclined-plane of lock module contacts with the round table surface cooperation of external screw thread fuse, prevents collision.Described first reset dress
Putting and include that pushing block and fork, described pushing block are arranged on ejector retainner plate and the outside of lower ejector retainner plate, described fork is arranged on dynamic
The outside of mould, fork distribution is rotatably connected with dynamic model, arranges torsion spring outside pin, and torsion spring matches with fork.When by plastics
After part ejects, torsion spring is rotated down under restoring force effect, and torsion spring drives fork to be rotated down, and fork pushes down on pushing block, pushes away
Block drives upper and lower ejector retainner plate homing downwards.

Side outer wall arranges first resetting means, arranges twice-die-opening mother tuber 24 outside dynamic model, and twice-die-opening mother tuber is shaped with female drag hook 25,
Female drag hook contacts with the straight block face 12 of tongue 11.When, after working of plastics injection mo(u)lding, lower compound plate 2 drives ejector sleeve fuse fixed plate
17, mould foot 19, upper ejector retainner plate 20, lower ejector retainner plate 21, ejector sleeve fuse 18, ejector sleeve 22, dynamic model 23 are moved rearwards by together with working of plastics,
Dynamic model 23 drives twice-die-opening mother tuber 24 to be moved rearwards by, due to female drag hook 25 and the straight block face 12 of tongue 11 of twice-die-opening mother tuber
Matching, therefore twice-die-opening mother tuber 24 drives tongue 11 to be moved rearwards by, tongue band active and inactive mold 8, inner screw sheath 14 and external screw thread
The most backward movement of fuse 15, makes mould first from opening realization die sinking for the first time between tooth bar fixed plate 3 and cover half 8, and due to
Upper compound plate 1, tooth bar fixed plate 3, tooth bar 7 and lock module 4 remain stationary as, and therefore rack drives external screw thread fuse 15 rotates, outside making
Screw thread fuse rotates while axially outwardly moving along the female thread of inner screw sheath 14, makes external screw thread fuse outwards deviate to mould
The internal thread hole of materials and parts, and lower compound plate 2 drives ejector sleeve fuse fixed plate 17, mould foot 19, upper ejector retainner plate 20, lower ejector retainner plate 21, pushes away
Tube core 18, ejector sleeve 22, dynamic model 23 and working of plastics continue to be moved rearwards by, when tongue 11 lower end, cover half 8 side oblique surface 13 with
When the public drag hook 6 of twice-die-opening public affairs block 5 contacts, public drag hook inwardly promotes tongue 11 through oblique surface 13, makes tongue retraction spring
In groove 9, thus causing tongue also to disengage with female drag hook 25, now mould is gradually opened at dynamic model 23 and cover half 8, mould
Twice-die-opening, is finally driven ejector sleeve 22 by working of plastics ejection device by upper and lower ejector retainner plate 20,21.This programme injection mold screw thread
Eight inner threaded core-pulling mechanisms of tooth bar formula, utilize tooth bar 7 and the cooperation of external screw thread fuse 15, external screw thread fuse and female thread
The cooperation of set 14, in conjunction with twice-die-opening public affairs block 5, twice-die-opening mother tuber 24 and the cooperation of tongue 11, makes mould first solid from tooth bar
Determine to open between plate 3 and cover half 8, external screw thread fuse 15 rotary core pulling, then make mould from die sinking between dynamic model 23 and cover half 8, incite somebody to action
Working of plastics automatic ejection demoulding, and without workman, working of plastics and inserts taking-up are put in fixture again and loose core, thus easy to operate,
Alleviate the labor intensity of workman, improve production efficiency.Described ejector sleeve fuse 18 external wall of upper portion has pass hopper 26, closes material
The inwall of groove is tiltedly to close charge level 27, and an outer wall of screw thread fuse 15 is shaped with corresponding inclined-plane outside, external screw thread fuse 18
One is matched through working of plastics with the pass hopper 26 of ejector sleeve fuse.Owing to the motion of external screw thread fuse 18 should be born radially
Rotary motion, moves before and after also bearing axially, and its action is the most complicated, so necessarily requiring during being molded steady
Firm, of external screw thread fuse 18 is coordinated with the charge level 27 that tiltedly closes closing hopper 26 by inclined-plane so that close material sealing position more accurate
Really.The other end of described external screw thread fuse 18 is round table surface 28, and round table surface matches with the inclined-plane of lock module 4 inwall.Make matched moulds
When lock module 4 resets, the inclined-plane of lock module contacts with round table surface 28 cooperation of external screw thread fuse 18, prevents collision.Described
First resetting means include that pushing block 29 and fork 30, described pushing block 29 are arranged on outside ejector retainner plate 20 and lower ejector retainner plate 21
Side, described fork is arranged on the outside of dynamic model 23, and fork distribution 31 is rotatably connected with dynamic model, arranges torsion spring outside pin,
Torsion spring matches with fork.After being ejected by working of plastics, torsion spring is rotated down under restoring force effect, torsion spring drive fork 30 to
Lower rotation, fork pushes down on pushing block 29, and pushing block drives upper and lower ejector retainner plate 20,21 homing downwards.
