Description
Technical field
The utility model relates to the opening and closing mould and the clamping mechanism of plastic draw-blow machine, belongs to the plastics machinery field, is mainly used in to produce mineral water bottle, oil bottle and bottle for cosmetics etc.
Background technology
Adopt to annotate stretch blow and produce hollow plastic container,, at first raw material is made the bottle pipe, by heater the bottle pipe is heated again by injection machine as mineral water bottle, oil bottle and bottle for cosmetics etc., then by plastic draw-blow machine to bottle pipe stretch blow moulding.The basic structure of plastic draw-blow machine is frame, template, and opening and closing mould and clamping mechanism and Stretch and Blow Mechanism etc. are formed.Though the opening and closing mould and the clamping mechanism kind of existing plastic draw-blow machine are more, it is little that ubiquity mold clamping force, particularly when blowing; clamp force is little; therefore and the mould that occurs rising, be molded as bottle (workpiece) and scrap, will seriously influence product quality and production cost in case rise.Another shortcoming is to have one to be fixed form in its three templates of prior art, and the stroke of die sinking or matched moulds is long, needs the time many, inefficiency.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of clamp force big, overcome the mould that rises, and it is reliable to operate steadily, and the opening and closing mould is the opening and closing mould and the clamping mechanism of plastic draw-blow machine rapidly.
Opening of the utility model plastic draw-blow machine; the technical scheme of matched moulds and clamping mechanism is: be mounted in the front template on the frame; middle template and rear pattern plate; each template is linked to each other by pull bar; between front template and middle template, blow mold is installed; on middle template and rear pattern plate, install and open; clamping; it is characterized in that described opening; clamping is at the frame upper mounting rail; front template; the guide rail slide block is equipped with in middle template and rear pattern plate bottom; the guide rail slide block matches with guide rail; in the rear pattern plate outside matched moulds cylinder is installed; the matched moulds cylinder piston rod is in matched moulds cylinder connecting plate is fixed on the template; on matched moulds cylinder connecting plate; the locked mode cylinder is installed respectively down; on; be shaped on groove on the following locked mode cylinder piston rod; last locked mode cylinder piston rod and matched moulds cylinder piston rod pass the long slot bore on the flashboard; flashboard by about two block pressur plates be fixed on the rear pattern plate; the fixing flashboard cylinder at the rear pattern plate top, the flashboard cylinder drives flashboard, at middle template and rear pattern plate bottom installation lazy-tongs.
Opening of the utility model plastic draw-blow machine; matched moulds and clamping mechanism; when matched moulds; the matched moulds cylinder piston rod stretches out; template moves toward front template in the promotion; (the locked mode cylinder piston rod is motionless with respect to the locked mode cylinder to the locked mode cylinder piston rod along with middle template is moved together simultaneously; promptly not flexible); behind the matched moulds; the action of flashboard cylinder; stretch out the flashboard cylinder piston rod, the long slot bore on the flashboard is matched with the groove of last locked mode cylinder piston rod, the flashboard bottom surface moves down into down the groove interior (just having limited the distance between middle template and the rear pattern plate like this) of locked mode cylinder piston rod; but the side of flashboard and groove also can be gapped; so the locked mode cylinder intake passes to power on the flashboard by piston rod; eliminate the gap, reach the locked mode purpose.Because the mould of rising power is arranged when bottle blowing; and the pressure that the matched moulds cylinder is provided is not enough; offset the mould power that rises so increase the clamping mechanism supplementary pressure, the prior art clamping often adopts mechanical locked mode, and pressure is little; bumpy motion; and this clamping makes locked mode pressure bigger owing to be furnished with guillotine mechanism and two locked mode cylinders specially, makes locked mode more steady reliable; guarantee the mould that do not rise, improve product percent of pass.When die sinking, the venting of locked mode cylinder, the piston rod withdrawal of flashboard cylinder, make on the flashboard and move, be separated with the groove of locked mode cylinder piston rod (at this moment locked mode cylinder piston rod just can move left and right), the piston rod of matched moulds cylinder withdrawal then, make preceding, middle template separately, i.e. die sinking.
The opening and closing mould and the clamping mechanism of the utility model plastic draw-blow machine; its described lazy-tongs are that the synchromesh gear seat is installed on frame; two gears are arranged in the synchromesh gear seat, each gear both sides respectively be fixed in synchronous tooth bar on template and the rear pattern plate be meshed.Lazy-tongs are along with opening; clamping moves together; when matched moulds; template moved toward front template during the matched moulds cylinder piston rod promoted; the tooth bar on the template moves forward in being fixed on thereby drive; this rack and pinion is meshed and makes gear rotation and drive the tooth bar that is fixed on the rear pattern plate and move backward; thereby driving rear pattern plate moves backward (owing to the effect of pull bar; front template is moved backward) with rear pattern plate; make front template consistent with the movement velocity of middle template; open; matched moulds centering; steadily; realize that three templates move, shorten stroke, enhance productivity.
