Fig. 4 is that the utility model injection mold liftout attachment is finished the view after ejecting for the second time.
The specific embodiment
Please referring to Fig. 2, this injection mold liftout attachment has first liftout plate, 2, the first liftout plates, 2 tops and is provided with second liftout plate 7 in parallel.Be provided with pull bar 13 between first liftout plate 2 and second liftout plate 7.Pull bar 13 1 ends are provided with boss 132.This first liftout plate 2 is slidingly connected with pull bar 13 and can be butted on the boss 132 of pull bar 13.This second liftout plate 7 is fixed in pull bar 13 other ends.Second liftout plate, 7 belows are equiped with the compression spring 4 that ejects second liftout plate 7 and play the support column 3 of position-limiting action during to second liftout plate, 7 returns.First liftout plate 2 is provided with internal thread, make its with injection machine push-off pin 1 by being threaded.Be equiped with the push rod 5 that is used to promote runner and cast gate 9 middle parts on first liftout plate 2, be used to promote the push rod 10 of runner and cast gate 9 sidepieces, be used to promote the goods push rod 12 that goods 8 are positioned at the die joint upper portion.Second liftout plate, 7 tops are equiped with and are used to promote the core bar 11 that goods 8 stretch into the die joint lower portion.In addition, for guaranteeing first liftout plate 2 and second liftout plate, 7 energy easy motions, this liftout attachment also is provided with the guide pillar 14 that passes first liftout plate 2 and second liftout plate 7.
After the mould die sinking, cover half leaves goods 8 and goods when not ejecting state, and first liftout plate 2 is butted on the boss 132 of pull bar 13, the spacing maximum of first liftout plate 2 and second liftout plate 7.Though the power that has compression spring 4 to provide can make 7 motions of second liftout plate, drive 2 motions of first liftout plate by the pull bar on second liftout plate 7 13 again, be processed with internal thread on first liftout plate 2, it is threaded with the push-off pin 1 of injection machine.Therefore, the push-off pin 1 of injection machine has limited the motion of first liftout plate 2, and the thrust that first liftout plate 2 overcomes spring 4 by pull bar 13 limits the motion of second liftout plate 7.So each liftout plate transfixion after the die sinking.
Please be simultaneously referring to Fig. 3, when ejecting for the first time, first liftout plate 2 and second liftout plate 7 will drive goods push rod 5,10,12 simultaneously and core bar 11 ejects together, and the side direction male and fomale(M﹠F) of goods 8 just can not produced in the die cavity the inside and take off by force like this.When being positioned at promptly to finish after the die joint upper portion breaks away from die cavity, goods 8 eject for the first time.Its process of ejecting is: the cover half template breaks away from goods 8 after the die sinking, and goods 8 and cast gate are separated, and goods 8 and runner and cast gate 9 are in the dynamic model side.Injection machine push-off pin 1 promotes 2 motions of first liftout plate then, and first liftout plate 2 drives goods push rod 12, runner and 5,10 motions of cast gate push rod.In 2 motions of first liftout plate, second liftout plate 7 moves with first liftout plate 2 under the effect of compression spring 4, and second liftout plate 7 drives core bars 11 with goods 8 releases.Pull bar 13 plays the effect of guaranteeing that second liftout plate 7 and first liftout plate 2 are synchronized with the movement at this moment.After goods 8 broke away from the dynamic model die cavity, runner and cast gate 9 came off automatically, and goods 8 are still stayed on the core bar 11.Second liftout plate 7 contacted with dynamic model and stopped to eject motion this moment, finished ejecting for the first time.Because second liftout plate 7 and first liftout plate 2 eject in the process in the whole first time and all be synchronized with the movement, first liftout plate 2 and second liftout plate 7 spacing at this moment still remain maximum.
Please referring again to Fig. 4, finish eject for the first time after, second liftout plate 7 contact stop motion with dynamic model, goods 8 have broken away from the dynamic model die cavity at this moment to be stayed on the core bar 11, for forced stripper mechanism is got ready.Injection machine push-off pin 1 continuation promotion first liftout plate 2, the first liftout plates 2 slide on pull bar 13 and drive goods push rod 12 release goods 8.In the process that first liftout plate 2 is promoted once more, the pull bar 13 bottom boss 132 and first liftout plate 2 are thrown off, be located at core bar 11 transfixions on second liftout plate 7, therefore, when goods 8 die joint upper portions are pushed out, goods 8 stretch into the pulling force that the die joint lower portion is subjected to goods 8 other parts, strain disengaging core bar 11 outwards takes place drop automatically then, finish ejecting and forced stripper mechanism for the second time.
After goods come off, injection machine push-off pin 1 is return, because injection machine push-off pin 1 and first liftout plate 2 are by being threaded, so can drive first liftout plate 2 rollback together when injection machine push-off pin 1 is return, first liftout plate, 2 drive push rods 5,10,12 are rollback together.When first liftout plate 2 had just begun rollback, the pull bar 13 bottom boss 132 and first liftout plate 2 were thrown off, and second liftout plate 7 is subjected to the elastic force effect of spring 4, so second liftout plate 7 and core bar 11 still remain static.When first liftout plate 2 return back to after pull bar 13 bottom boss 132 contact, pull bar 13 drives second liftout plate, 7 returns, and second liftout plate 7 drives core bar 11 again with liftout plate 2 rollbacks.After rollback put in place, support column 3 contacted restriction second liftout plate 7 with second liftout plate 7 and core bar 11 continues to retreat.This moment, injection machine dynamic model and cover half matched moulds began injection moulding next time.
