horizontal guide hole 11, inclined guide pillar 4 are matched with oblique guide hole, and horizontal guide block 12, horizontal guide block and cross is arranged in the side of insert 7 after dynamic model Guide hole matches, and has the imitative of injection molding before dynamic model after insert, dynamic model between insert, left Loose core block, right Loose core block and solid plate 3 Rattan plastic chair, imitative rattan plastic chair are formed with backrest 14, seat board 15 and chair leg, the imitative rattan flower-pattern layer of protrusion are formed on backrest and seat board 16, it is characterised in that：Spring 17 is set between the lower compound plate 2 and moving template 5, slider guide 18 is set on lower compound plate 2, is led Sliding block is mutually fixed through fastener and lower compound plate, and the side of slider guide is formed with inclined guide runner 19, is provided in preceding moving die insert It perforates, lower Loose core block 20 is set in perforation, lower Loose core block is matched with the imitative rattan flower-pattern layer 16 on imitative rattan plastics chair seat board 15, under The other side of Loose core block connects sliding block 21, and sliding block is matched with the guide runner 19 of slider guide 18, the one of insert 7 after dynamic model Fixed plate 22 is arranged in side, and chair leg core pulling oil cylinder 23 and guide post 24 are arranged in fixed plate, and the piston rod of chair leg core pulling oil cylinder passes through solid Insert 7 is matched with chair leg after fixed board and dynamic model, 24 other end connection plate 25 of guide post, and bottom is pushed up in the front side setting side of mounting plate Foreboard 27 is pushed up in plate 26 and side, and side thimble 28 is arranged on side roof and floor and side top foreboard, and oil cylinder 29 is pushed up in the rear side setting side of mounting plate, Fixing seat 30 is arranged in the outer wall of insert 7 after dynamic model, and the outer wall setting of solid plate 3 is opened oil cylinder 31 three times, is opened oil cylinder three times Piston rod be connected with fixing seat.After imitative rattan plastic chair injection molding, the die sinking of injection molding machine driven mold is first existed by spring 17 It pushes lower compound plate 2 to move down under the action of restoring force, is opened mold for the first time between lower compound plate and moving template 5, at this time Lower compound plate drives slider guide 18 to move downwardly together, and the guide runner 19 and sliding block 21 of slider guide cooperate, to drive sliding block Facilitate along the inclination of guide runner to side and move, sliding block drives lower Loose core block 20 to the mobile extraction imitative rattan plastics seat in side The imitative rattan flower-pattern layer 16 of 15 surface of plate protrusion, after Loose core block 20 extracts imitative rattan flower-pattern layer 16 out to side instantly, the lower drive of compound plate 2 is led Insert 6 continues to move down before sliding block 18, sliding block 21, lower Loose core block 20, moving template 5, dynamic model, and is opened oil cylinder 31 three times Piston rod then holds fixing seat 30, and fixing seat holds insert 7, left Loose core block 8, right Loose core block 9, chair leg after fixed plate 22, dynamic model Core pulling oil cylinder 23, imitative rattan plastic chair are motionless, and mold is opened from insert 7 after insert 6 and dynamic model before dynamic model at this time, inlay before making dynamic model Block moves down abjection imitative rattan plastic chair, makes to reserve enough spaces on front side of imitative rattan plastic chair, then by chair leg core pulling oil cylinder The chair leg of 23 extraction imitative rattan plastic chairs, then die sinking oil cylinder 31 pushes insert 7, a left side after fixing seat 30, fixed plate 22, dynamic model three times Loose core block 8, right Loose core block 9, chair leg core pulling oil cylinder 23, imitative rattan plastic chair move downwardly together, the oblique guide hole 10 of left and right Loose core block The cooperation of inclined guide pillar 4 and horizontal guide hole 11 and horizontal guide block 12 with solid plate 3 cooperate, and move down left and right Loose core block 8,9 Chair leg outer wall gradually is extracted out to two sides simultaneously, and foreboard is finally pushed up by the piston rod push side roof and floor 26 and side of side top oil cylinder 29 27, the lateral ejection device of imitative rattan plastic chair that foreboard drives side thimble 28 that will complete core pulling is pushed up in side roof and floor and side.This programme is imitative Rattan plastic chair dynamic model side floating quadrangle core-pulling mechanism, is opened in three times, and die sinking for the first time makes lower Loose core block 20 first extract imitative rattan modeling out The imitative rattan flower-pattern layer 16 that material chair seat board 15 protrudes above, second of die sinking take off insert 6 before moving template 5 and dynamic model with imitative rattan plastic chair From contact, to enough ejection spaces are reserved on front side of imitative rattan plastic chair, third time die sinking makes fixing seat 30, fixed plate 22, dynamic model Insert 7, left Loose core block 8, right Loose core block 9, chair leg core pulling oil cylinder 23, imitative rattan plastic chair etc. are in suspended state afterwards, finally by side Oil cylinder 29 is pushed up by imitative rattan plastic chair ejection device, guarantees that product can be demoulded smoothly.
