II push pedal 2 be each side provided with reed swing hook assembly 19, reed swing hook assembly 19 has the reed 19-2 of swing hook 19-1 and angle-square-shaped, swing hook 19-1 is hinged in II push pedal 2 by bearing pin 19-3, the bottom of reed 19-2 is fixed on the bottom surface of II push pedal 2, hold in the palm on swing hook lateral surface on its top, and the upper inner face of swing hook 19-1 is inclined-plane 19-1-1; The middle part of swing hook 19-1 is provided with step 19-1-2, the I push pedal base plate 3-1 of I push pedal 3 is wider than I push pedal mainboard 3-2 on the width of left and right, form step, reed swing hook assembly 19 is under off position, the step 19-1-2 of swing hook 19-1 is buckled on the step of I push pedal 3, and formation is dynamically connected. In the time moving in I push pedal 3, I push pedal 3 drives the upper shift-in of swing hook 19-1 to drive in II push pedal 2 by step and moves.
I push pedal 3 is provided with sleeve rotating assembly 18, described sleeve rotating assembly 18 has 3 to 4 support bar 18-1 and pushing block 18-2, thrust ball bearing with flat seat 18-3 and sleeve pipe 18-4, the present embodiment is 4 support bar 18-1, the afterbody of support bar 18-1 inserts by core fixing plate 5 and in the chamber of moving platen 6, is connected with pushing block 18-2 and stretches out pushing block 18-2, on tail end face, be provided with packing ring 18-5 and nut, fixed by screw, for the sleeve pipe 18-4 of inverted T-shaped is enclosed within on core 13, the bottom of sleeve pipe 18-4 is by the edge axial limiting of four packing ring 18-5. On core 13 and between sleeve pipe 18-4 and pushing block 18-2, be provided with above-mentioned thrust ball bearing with flat seat 18-3.
The bottom surface of core fixing plate 5 is provided with 2 to 4 guide pillars 17, and the present embodiment is provided with 2 guide pillars 17, and in I push pedal 3, corresponding each guide pillar 17 is provided with the pilot hole mating with guide pillar.
In helical gear die cavity piece fixed head 8, the fixed head 7 of inserting, dynamic model 6 and core fixing plate 5, be provided with pilot hole, in the pilot hole of helical gear die cavity piece fixed head 8, the fixed head 7 of inserting, be respectively equipped with upper guide bush 15 and lower guide pin bushing 16, the setting of this pilot hole and guide pin bushing is for coordinating with the guide pillar that is fixed on cover half part.
The present embodiment is for injecting molding die, and mould is arranged on horizontal injection machine, and after injection moulding finishes, injector clamping mechanism fails, and under the effect of injector die opening mechanism, dynamic model part retreats to institute's allocation downwards along the I-I of die joint shown in Fig. 2.
Injector push rod 21 promotes I push pedal 3, drives II push pedal 2, sleeve rotating assembly 18, connection push rod 10, release link 14 to move up together by the swing hook 19-1 in reed swing hook assembly 19. Helical gear die cavity piece fixed head 8 is connected the promotion of push rod 10, drives plastic helical gear 20 depart from core 13 and drive distance rod 9 to move up simultaneously. In the time that core fixing plate 5 is encountered on the inclined-plane of the swing hook 19-1 of reed swing hook assembly 19, swing hook 19-1 outwards swings and separates with I push pedal 3 gradually around bearing pin 19-3, meanwhile, the head of distance rod 9 contacts with the fixed head 7 of inserting, helical gear die cavity piece fixed head 8 no longer moves up, and completes the one-level demoulding (seeing accompanying drawing 3).
Injector push rod 21 continues upwards to promote I push pedal 3, and now II push pedal 2 and reed swing hook assembly 19 no longer move, and due to the position-limiting action of distance rod 9, sleeve rotating assembly 18 starts to release plastic helical gear 20. Under the release effect of injector push rod 21, promoting plastic helical gear 20 by support bar 18-1, pushing block 18-2, thrust ball bearing with flat seat 18-3 and the sleeve pipe 18-4 of I push pedal 3, sleeve rotating assembly 18 moves forward along the smooth and easy rotation of spiral characteristic line of helical gear die cavity piece inner side, complete the secondary demoulding (seeing accompanying drawing 4), finally realize the smooth demoulding of plastic helical gear.
Due to after the one-level demoulding, plastic helical gear separates with core, in secondary knockout course, the rotation of plastic helical gear only needs the impact of frictional resistance between consideration and helical gear die cavity piece inner side, for the rotation of sleeve pipe 18-4 is effectively passed to plastic helical gear, offer at least one technology groove 18-4-1 in the end of sleeve pipe 18-4, see accompanying drawing 5-6. The about 0.5-1mm of these technique groove depths, wide about 2mm, do not affect Forming Quality and the serviceability of plastic helical gear.
For distortion after avoiding plastic helical gear to produce, adopt the stripping means of releasing at a slow speed in push.
When matched moulds, the die joint of cover half part acts on release link 14, release link 14 promotes I push pedal 3, II push pedal 2 turns back to original position, in this process, the support bar 18-1 of sleeve rotating assembly 18 drives pushing block 18-2, thrust ball bearing with flat seat 18-3 to reset, and by the effect of packing ring 18-5, sleeve pipe 18-4 is resetted simultaneously.
Due to the elastic returning of the reed 19-2 of reed swing hook assembly 19, swing hook 19-1 leaves after core fixing plate 5, resets around bearing pin 19-3, continues I push pedal 3 together with II push pedal 2 padlocks.
For making sleeve pipe releasing smooth rotation when plastic helical gear, the lower surface of the upper surface of sleeve pipe 18-4 and packing ring 18-5 leaves the gap of 1mm left and right, does not contact with packing ring, thereby reduced the spin friction resistance of sleeve pipe while ensureing sleeve rotating release. The 1mm gap of sleeve pipe reset phase difference, utilizes motional inertia on the one hand, and the injection pressure while entering die cavity by molten plastic on the one hand in the time of moulding back into sleeve pipe the original position of moulding.
