Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of sleeve cap injection mold, comprises base plate 1, eject backing plate 2, liftout plate 3, moving platen 4, solid plate 5, cover half backing plate 6, fixed die insert 7, cast gate centring ring 8, sprue bush 9, sprue puller 10, push rod 11, Angle Pin 12, slide block 13, guide pillar 14, push back pin 15, circular arc slide block 16, bearing fixed part, latch segment 19, oil cylinder connector 21, cylinder rod 22, oil cylinder seat 23, oil cylinder 24, screw 25, cover half ladder insert 26, dynamic model ladder insert 27, moving die insert 28, first arc guide rail pressing plate 29 and the second arc guide rail pressing plate 30, base plate 1 connection ejects backing plate 2, eject backing plate 2 and connect liftout plate 3, moving platen 4 connects solid plate 5, solid plate 5 connects cover half backing plate 6, cast gate centring ring 8 connects sprue bush 9, sprue bush 9 connects sprue puller 10, sprue puller 10 connection ejects backing plate 2, push rod 11 connection ejects backing plate 2, Angle Pin 12 connects cover half backing plate 6, guide pillar 14 connects cover half backing plate 6, push back pin 15 connection ejects backing plate 2, circular arc slide block 16 connection bearing fixed part, latch segment 19 connection ejects backing plate 2, oil cylinder connector 21 connects cylinder rod 22, cylinder rod 22 connects oil cylinder seat 23, oil cylinder seat 23 connects oil cylinder 24, screw 25 hammers into dynamic model ladder insert 27, cover half ladder insert 26 connects dynamic model ladder insert 27, moving die insert 28 connects the first arc guide rail pressing plate 29, second arc guide rail pressing plate 30 connects moving platen 4.
Wherein, Angle Pin angle 20 °, active length >96mm, latch segment angle is 22 °, and bearing fixed part comprises bearing 17, hold-down screw group 18 and connecting rod 20, and bearing 17 is connected and fixed set screws 18, and connecting rod 20 is connected and fixed set screws 18.
The course of work: after working of plastics injection moulding cooling, move after starting dynamic model, somatotype between moving platen and solid plate, slide block completes under the effect of Angle Pin looses core, and on slide block, core all departs from working of plastics; Latch segment departs from circular arc slide block, and start oil cylinder switch, oil cylinder outwards works, oil cylinder connector is driven outwards to move by cylinder rod, connecting rod on oil cylinder connector pulls circular arc slide block to move along arc orbit, completes loosing core of arc section, and arc section core departs from working of plastics; Dynamic model part is moved after continuing, and lathe ejects part shake-up and ejects backing plate and liftout plate, drive push rod and sprue puller to travel forward, working of plastics and cast gate are all ejected outside mould, take out working of plastics.During matched moulds, start oil cylinder and inwardly move, matched moulds after circular arc slide block is first resetted, push back pin promotes to eject backing plate and liftout plate, and complete push rod and sprue puller reset, slide block resets by Angle Pin, latch segment, by circular arc slider locking, completes whole matched moulds, carries out next mould injection moulding.Wherein oil cylinder connector and circular arc slide block all install bearing, make connecting rod smooth movement in pulling.
