The operation principle of super-large size plastic molding equipment with above structure is as follows：

Under original state, three-way diverter valve 408 connects changeover portion 417 and accumulator 404, disconnects changeover portion 417 and nozzle Section 401 and accumulator 404 and nozzle segment 401, nozzle segment 401 is separated with lower die 302, the rear side positioned at lower die 302. Plastic raw materials are sent by self-feeding subsidiary engine in barrel 402 in advance, and after the completion of preheated, servo-hydraulic electrical system 20 starts Hydraulic motor 410, and then feeding spiro rod 403 is driven to rotate, it is sent so that the plastics in barrel 402 enter through feed zone 416 Expect in screw rod 403, under the collective effect of 403 outside heating collar of feeding spiro rod and hydraulic motor 410, entered after plastic molten melt Section 417 is crossed, then is transferred in the accumulator 404 of automatic heat preserving through three-way diverter valve 408, so as to push the first of accumulator 404 the work Stopper rod moves backward, and then tailstock 407, the second piston bar of injection cylinder 405 and electron injection ruler 409 is driven to move back together It is dynamic.After setting position is moved on to after the electron injection ruler 409, that is, reach required shot, servo-hydraulic electrical system 20 controls oil Pressure motor 410 stops operating, and so as to stop feeding into accumulator 404, accumulator 404 enters keeping warm mode.Servo-fluid piezoelectricity Gas system 20 drives whole shifting oil cylinder 412 to act, and whole shifting oil cylinder 412 pushes oil cylinder seat 406 to move forward, and drives 404 He of accumulator Nozzle segment 401 moves forward together to close to the direction of mold 30, until nozzle segment 401 and 303 phase of die locating ring in mold 30 Dynamic sealing is realized in contact.Three-way diverter valve 408 commutates, and connects accumulator 404 and nozzle segment 401, disconnects 417 He of changeover portion Accumulator 404 and changeover portion 417 and nozzle segment 401, super-large size plastic molding equipment enter injection stage, servo-fluid piezoelectricity Gas system 20 drive injection cylinder 405 act, then injection cylinder 405 second piston move forward, so as to drive tailstock 407, The First piston bar and electron injection ruler 409 of accumulator 404 move forward together so that molten plastic is through nozzle in accumulator 404 Enter in die cavity after section 401, die locating ring 303 and lower die 302.Servo-hydraulic electrical system 20 controls lift cylinder 504 to act, Move down lift cylinder 504, then lift cylinder 504 is in idle stroke, and sliding block 501 glides by dead weight, and drives upper mold 301, molding electricity Sub- ruler 505 and master cylinder 503 move down together, and the epicoele of master cylinder 503 quickly sucks hydraulic oil by prefill valve, when molding electronics After ruler 505 moves down into designated position, servo-hydraulic electrical system 20 controls 504 stopping of lift cylinder action.When electron injection ruler 409 After being advanced to designated position, servo-hydraulic electrical system 20 controls 405 stopping of injection cylinder action, then is melted in accumulator 404 Plastic injection is completed, and three-way diverter valve 408 commutates, returns back to original state, and squeezing mechanism 40 enters subsequent cycle standby phase. Servo-hydraulic electrical system 20 controls 30 inner flow passage of mold to close and lift cylinder 504 is controlled to move down, while servo-hydraulic is electrically Main oil pump rapid refueling, increase into master cylinder 503 in 20 control of system, sliding block 501 drive 301 downlink of upper mold, are gradually compacted Molten plastic in die cavity, and constantly upper pressure, when the value of feedback of the pressure sensor in the control of servo-hydraulic electrical system 20 reaches After setting value, the control of servo-hydraulic electrical system 20 stops the action refueling in master cylinder 503, and clamping 50 enters automatic Cool down pressurize program.Preferably, it can be passed through cooling water automatically in mold 30, equably to cool down the product in mold 30.It treats cold But after pressurize reaches setting time, the control master cylinder 503 of servo-hydraulic electrical system 20 acts, makes the high pressure chest of master cylinder 503 Release, later, servo-hydraulic electrical system 20 controls lift cylinder 504 to act again, uplink, then lift cylinder 504 is with 501 He of movable slider The uplink together of upper mold 301 so that upper mold 301 is detached with lower die 302, and product stays in the upper mold 301 or mould of mold 30 as needed In the lower die 302 of tool 30.Auxiliary taking mechanical hand gos deep between the upper mold 301 of mold 30 and lower die 302, catches product or crawl Product backed off after random.So far, the injection molding cycle of a product is completed.

Further, as shown in Fig. 1 or Fig. 3, the squeezing mechanism 40 further includes the support for being fixed on 404 periphery of accumulator Item 413 and guide wheel assemblies 414, the fuselage 101 in fixed frame 10 is fixed in the lower end of the guide wheel assemblies 414, described The directive wheel of 414 upper end of guide wheel assemblies is in contact with support bar 413, moves forward or moves afterwards steady so as to improve accumulator 404 Property.In order to ensure the reliability of nozzle segment 401 and 303 dynamic sealing of die locating ring, the squeezing mechanism 40, which further includes, to be located at Fixed frame 10 and the whole hydraulic pressure adjustment component 415 moved between guide rail 411, hydraulic pressure adjustment component 415 include support cylinder, With the upper end of the piston rod of support cylinder it is mutually fixed adjustment stud and with adjust the matched adjusting nut of stud, it is described The upper end and whole shifting 411 thread fitting of guide rail, the adjusting nut for adjusting stud are abutted against with integrated guide rail.It is adjusted by hydraulic pressure 415 tunable integer of component moves the height of guide rail 411 and oil cylinder seat 406, and then adjusts the height of nozzle segment 401, so as to ensure to spray Mouth section 401 and the reliability of 303 dynamic sealing of die locating ring；At this point, the length of the guide wheel assemblies 414 in the up-down direction Degree is also adjustable.

As shown in figures 2 or 4, the shifting formwork guide rail 509 in the fixed frame 10 with front and rear extension and opposite shifting formwork The mobile work platform 508 that guide rail 509 can be moved forward and backward, the lower die 302 are mounted in mobile work platform 508, so that under Mould 302 can be removed from fixed frame 10, convenient for the replacement of mold 30.Meanwhile in mobile work platform 508 and fixed frame 10 Underbeam 103 or deckle board 105 between pass through promote automatic positioning；When positioning is more than setting accuracy, then it is used to lock mobile work Make 510 akinesia of locking cylinder of platform 508.In addition, it is equipped on upper beam 102 or deckle board 105 in the fixed frame 10 Safety pin 60, when lift cylinder 504 goes upward to upper limit position with movable slider 501, sliding block 501 is carried out certainly by safety pin 60 Lock, anti-limited slip block 501 drop.Furthermore spin safe column is installed on the column 104 or deckle board 105 in the fixed frame 10 70, after sliding block 501 goes upward to upper limit position, spin safe column 70 is released, spin safe column 70 is made to be located under sliding block 501 Side, therefore, when spin safe column 70 does not reset, sliding block 501 is unable to downlink.Control box is further fixed on the fixed frame 10 80 and maintenance ladder 90, control box 80 is for operating a whole set of super-large size plastic molding equipment, 90 personnel convenient to overhaul of maintenance ladder maintenance Super-large size plastic molding equipment.

In conclusion this application involves super-large size plastic molding equipment have the advantages that：
