Description
Technical field
The utility model relates to injection-moulding device technical field, specially a kind of vertical injection molding machine.
Background technique
Vertical injection molding machine is a mechanical equipment.Usually by injecting systems, Clamping System, hydraulic transmission system, electrical
The composition such as control system, lubricating system, heating and cooling system, safety monitoring system.
Injecting systems are one of most important component parts of injection molding machine, generally there is plunger type, screw, screw rod preformed plunger
3 kinds of principal modes of injecting type.Most widely used at present is screw.Its effect is, in a circulation of injection molding material machine, energy
Before the deadline by after the plasticizing of a certain number of plastic heatings, under certain pressure and speed, will be melted by screw rod
Plastics inject in mold cavity.
The nozzle of injection molding machine is the union piece between machine barrel and mold, when injection molding, under the action of screw rod thrust, and melting
Plastics the type chamber of mold is injected by nozzle with very high flow velocity.The nozzle of injection molding machine mainly has open-type nozzle, locked
The nozzle of nozzle and special construction.Open type (through type) nozzle, which refers to that the channel of nozzle always is, to be open, not to
The valve body closed or opened, when machine barrel front end and nozzle temperature are excessively high, or machine barrel front end storing is excessive in a high voltage state, just holds
It is also easy to produce " salivation " phenomenon, so that plastics is not being started injection under the open present situation of mold, unexpectedly robs and be introduced into sprue and enter
Mouth is simultaneously hardened under the cooling effect of template, and melt is interfered swimmingly to enter type chamber.
For example, application No. is 201320590857.4 Chinese utility model patents to disclose a kind of injection molding machine nozzle, it should
Utility model carries out locking and unlatching to the runner in nozzle using plunger radial, and plunger closes and blocks nozzle stream before being molded
Road, effectively prevents " salivating " phenomenon, and when injection molding, plunger is opened, the fluid of melting be able to enter nozzle to plastic mould into
Row injection molding, since using radial manner control nozzle opening and closing, when plunger is opened, plunger is retracted in nozzle wall, and nozzle flow channel is complete
It opens, resistance will not be generated to the fluid of melting, the pressure loss is small, and feeding effect is good；
But the existing injection molding machine nozzle has the following deficiencies: due to being vertical relation between plunger and injecting cavity, works as plunger
When injecting cavity is blocked, the melting charge in injecting cavity can apply motive force to plunger, since the motive force is vertical with plunger, and
The active force exists always, therefore the motive force can generate biggish destruction to plunger, influences integrally-built to use the longevity
Life.
