Description
Technical field
The utility model belongs to injection-moulding device field, and in particular to a kind of oil-leakage-prevention knot of two-plate injection molding machine high pressure cylinder
Structure.
Background technique
Currently, the two-plate injection molding machine of injection-moulding device manufacturer, the existing country, the high-voltage oil cylinder for high press-fitting mould are fixed on
On moving template, by the support and guiding of big thick stick.Self weight and stress due to big thick stick can be sagging, then unilateral in open mold to connect
Touching, therefore the sealing element of high pressure cylinder is easily worn, and damage, the oil leak of sealing element and big thick stick are caused after being further worn out, it can not be normal
Work.
Further more, the mechanical reaming type injection molding machine of domestic injection-moulding device manufacturer, driving mechanism are fixed on tailgate, the conjunction of driving mechanism
Mould oil cylinder pushes the toggle link in crank connecting rod mechanism, and the link motion that toggle mechanism is carried out pushes moving template along tie-bar axial direction
Movement.In molding motion process, moving template movement speed is raised to maximum value by zero quickly, slows down gradually again later, with song
Toggle link is gradually stretched to when terminating, and closure pressing speed zero, mechanism enters self-locking state (molding state), and mold clamping force is connected by toggle
What lever system formed the thrust amplification for molding hydraulic cylinder.In the past, since control precision does not reach requirement, this open mold
Kinetic characteristic meet very much machine requirement；But which limit the speed of open mold and extend circulation time.Therefore, it sends out
The injection molding machine high pressure cylinder folding modular system for opening up the development two-plate under existing technical conditions is trend of the times.
Utility model content
To overcome problems of the prior art, the utility model proposes a kind of leakproofs of two-plate injection molding machine high pressure cylinder
Oily structure solves the problems, such as to lead to the damage of sealing element and big thick stick, high pressure cylinder oil leak because of abrasion, and particular technique content is as follows:
A kind of leak-proof arrangement of two-plate injection molding machine high pressure cylinder, including solid plate component, moving template component, folding moulding oil
Cylinder component and the tie-bar for connecting three above component, the solid plate component is fixed on the rack, by open mold cylinder component
Push moving template component to solid plate component movement, the moving template component includes moving template, mounting plate and connects the moving template
With the connector of mounting plate, it is provided on the mounting plate for the embedding guide channel worn of the tie-bar, the folding mould oil cylinder
Component includes high pressure die cylinder component and quick die cylinder component, and the high pressure die cylinder component is installed in the installation
It is worn on plate and by the tie-bar and provides its piston, the high pressure die cylinder component is equipped with an opening-closing locking device, institute
It states and holds tie-bar when opening-closing locking is installed on molding tightly, when Yu Kaimo unclamps tie-bar；The quick die cylinder component is fixedly arranged on fixed
It is connect on template component and with described tie-bar one end.
In one or more embodiments of the utility model, the opening-closing locking device includes a locking nut, described
Locking nut is sheathed on the holding or release realized on the tie-bar to tie-bar.
In one or more embodiments of the utility model, there are four simultaneously symmetrical for the mounting plate tool of the moving template component
Live apart the quadrangle of connector, is respectively arranged with a high pressure die cylinder component and a corresponding tie-bar on each mounting plate.
Compared with prior art, the superiority of the utility model is embodied in: the high pressure die cylinder component and moving template
Component is integral, and the pull rod sliding is arranged in high pressure die cylinder component, and is assembled for clearance fit, is avoided and is being opened
Single edge contact in molding, therefore the sealing element of high-voltage oil cylinder component will not be worn leads to sealing element and big thick stick after will not wearing
Damage, high pressure cylinder oil leak guarantee that board works normally.Moreover, high pressure die cylinder component is separately mounted to moving template component
Quadrangle, the stress equalization of moving template, template deformation are small.The mold clamping force of die cylinder component is directly realized by by hydraulic, board
Clamp force is constant, the stress balance of four tie-bars, while the mold thickness variation similar to mold expanded by heating etc. is realized automatically
Compensation makes board and mold always be in good working state, extends the service life of board and mold；And open mold acts
It is to be completed by the direct driving template component of rapid mould opening-closing oil cylinder, avoids the multiple movement of traditional Curved Elbow Die Mechanism and turn
It changes, and causes the limitation of split closure pressing speed, shorten the open mold time, improve the efficiency of board.
