Description
Technical field
The utility model is specifically related to a kind of high speed injection motding machine.
Background technology
The principle of the injection (mo(u)lding) machine of existing market is to the melting state with solid shape plastics (pellet or powder) heating plasticizing, add the vasopressing injection mode and the plastics of melting state are injected the mold cavity of closed and locking, behind the pressurize cooling forming, take out, become plastic member product with definite shape.
The injection of injection (mo(u)lding) machine partly reaches movably integral body by barrel (and twine on it heating collar), feeding (plasticizing) screw rod, the nozzle that shoots material, pressurize (injection) oil cylinder, spiro driving device and penetrates platform and form.Screw rod relies on drive unit to rotate in the barrel of heating, thereby make solid shape plastics (pellet or powder) melting in barrel plastify and be transported to the front end of barrel, screw rod relies on pressurize (injection) oil cylinder that the plastics of melting state are injected in the die cavity of mould, and pressurize.
Whole action of injection is decomposed into: injection-pressurize-take out glue-melten gel, move in circles and all working is finished by screw rod.
Thin-walled class plastic in the market, its injection moulding characteristics are: injection volume is few, issuing velocity wants fast (because of plastics very easily cooling in mold cavity of melting state, cause that it is mobile poor), ejaculation pressure is big, so the molding time of goods just becomes the important consideration index of thin-walled class plasthetics.
At the said goods characteristics, the method that conventional injection machine adopts on the market is:
1, measures such as expanded motor, increasing oil pump and the through-flow diameter of increasing hydraulic pressure are in the hope of reaching the issuing velocity of moment; This way makes all raising speed of whole action of injection moulding achieve the goal.In the middle of the reality test (the processing thin-walled plastic soup bowl of injection moulding), its injection moulding process-cycle is 4-5 second.
2, additional accumulator (adding the liquid nitrogen machine usually) promotes injection speed; Adopt the method can only promote injection speed, actions such as melten gel, the mould of unblanking equally need the large-power hydraulic system to satisfy the shaping of goods.In the middle of the reality test (the processing thin-walled plastic soup bowl of injection moulding), its injection moulding process-cycle is 3-4 second.
More than two kinds of ways be improvement on common injection machine because each action is in the high-speed motion for a long time, each mechanical part is difficult to bear.Cause the life-span short, maintenance rate is high, goods are unstable, injection machine board vibration big, equipment manufacturing cost unfavorable aspects the such as high 1.5-2 of common injection machine (are doubly).
3, adopt the electric hydaulic injection machine, to improve injection speed.In the middle of the reality test (the processing thin-walled plastic soup bowl of injection moulding), its injection moulding process-cycle is 4-5 second.This type of injection machine cost height, price normally common injection machine 2-3 doubly.
More than three kinds of forms improve the way of injection speeds, do not change the sequentially-operating of original injection moulding: injection-pressurize-take out glue-melten gel.Its molding time that reduces thin-gage goods is to be cost with huge energy consumption.
The utility model content
