The locked mode opening device of the plastic injection molding machine has the advantages of compact structure, large mold locking force and quick mold opening speed.
Description
Technical field
The utility model relates to a kind of two plates, three plate injection (mo(u)lding) machine high-voltage lock moulds, quick die-sinking device, this device is mainly used in movable pull bar locking, play the locked mode effect, be applicable to the high-voltage lock mould occasion behind two plates, the three plate injection (mo(u)lding) machine matched moulds, clamp force is big, when causing product molding, can make product approval accurate, opening speed is fast simultaneously, the efficient height.
Background technology
Generally all be to use the connecting rod locked mode in the common plastics injection (mo(u)lding) machine, and the clamping of two plate injection (mo(u)lding) machines or special injection (mo(u)lding) machine does not have the locked mode connecting rod, conventional connecting rod locked mode typing inaccuracy, and the slow efficient of opening speed is not high.
The utility model content
Technical problem to be solved in the utility model be overcome deficiency of the prior art and provide a kind of compact conformation, easily manufactured, clamp force is big, opening speed is fast, the plastic-injection moulding machine locked mode die-sinking device of no connecting rod locked mode.
The technical scheme in the invention for solving the above technical problem is: this plastic-injection moulding machine locked mode die-sinking device, be arranged on the solid plate and be connected with pull bar, it is characterized in that: comprise the locking cylinder body, latching ram, alignment pin, the large tank lid, eject oil cylinder cover, eject piston rod, eject cylinder body, eject piston, eject oil cylinder cover, stud and inductive switch, the locking cylinder body is fixed on the solid plate, latching ram is arranged in the locking cylinder body, pull bar passes through solid plate, locking cylinder body and latching ram are with being threaded, latching ram respectively is equipped with an alignment pin up and down, the large tank lid is fixed on the locking cylinder body, large tank covers and is provided with inductive switch, described inductive switch is positioned near the alignment pin, ejecting the oil cylinder protecgulum is contained in large tank and covers, eject cylinder body with eject the oil cylinder bonnet with stud with eject the oil cylinder protecgulum and be connected, eject to be provided with in the cylinder body and eject piston, eject piston rod one end and eject piston and be connected, the other end passes and ejects oil cylinder protecgulum and large tank lid.
Described in the utility model eject piston rod and eject between the oil cylinder protecgulum be provided with oilless bearing.
Latching ram cross-sectional area described in the utility model is greater than ejecting the piston cross-sectional area.
The utility model compared with prior art has the following advantages: for solving the locked mode problem of no connecting rod locked mode, specially designed high-voltage lock mould, quick die-sinking device.Because the clamp force (need bear frictional force, injection force and the matched moulds tension force etc. of corresponding parts) during locked mode is big, and only need mould is opened (frictional force of bearing corresponding parts) during die sinking, mould opening force is less relatively and speed is corresponding fast.Therefore when design, require the coupling mechanism force of locking cylinder big, and it is relatively little to eject the ejecting force of oil cylinder; And system oil pressure operating pressure unanimity, according to F=PA(F operating pressure, P oil pressure operating pressure, A piston effective area), relatively the oil cylinder area also has different requirements, and the locking cylinder piston area is big, and it is little to eject the oil cylinder piston area.When mould assembling action is finished, hydraulic oil enters locking cylinder from locking cylinder body oil inlet and outlet, promotes latching ram and moves along the alignment pin direction, and make the sensed inductive switching of alignment pin, and latching ram quits work.Latching ram work simultaneously drives pull bar and moves, because pull bar and moving die plate are fixed with nut, also is that mould closes tightly so pull bar moves simultaneously, has played the effect of high-voltage lock mould.When the need die sinking, hydraulic oil is from ejecting the oil-feed of oil cylinder bonnet, promotion ejects piston and moves, promptly promote to eject piston rod, make to eject piston rod and withstand latching ram (hydraulic oil in the locking cylinder is fuel-displaced from the locking cylinder body) and move together, promptly pushing drawing rod and template are opened mould fast, make the sensed inductive switching of alignment pin throw off the die sinking release.Whole apparatus structure compactness, easily manufactured, clamp force is big, opening speed is fast.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, the utility model comprises locking cylinder body 1, latching ram 2, alignment pin 3, large tank lid 4, oilless bearing 5, ejects oil cylinder protecgulum 6, ejects piston rod 7, ejects cylinder body 8, ejects piston 9, ejects oil cylinder bonnet 10, stud 11, inductive switch 12, moving die plate 13, mould 14, pull bar 15, solid plate 16.
When mould assembling action is finished, hydraulic oil enters locking cylinder from locking cylinder body 1 oil inlet and outlet A, promotes latching ram 2 and moves along alignment pin 3 directions, and make alignment pin 3 sensed switches 12 inductions, and latching ram 2 quits work.Latching ram 2 work simultaneously drive pull bar 15 and move, because pull bar 15 and moving die plate 13 usefulness nuts are fixed, also are that mould closes tightly so pull bar 15 moves simultaneously, have played the effect of high-voltage lock mould.When the need die sinking, hydraulic oil is from ejecting the B oil-feed on the oil cylinder bonnet 10, promotion ejects piston 9 and moves, promptly promote to eject piston rod 7, make that to eject the hydraulic oil that piston rod 7 withstands in the latching ram 2(locking cylinder fuel-displaced from A) move together, promptly pushing drawing rod 15 and moving die plate 13 are opened mould fast, make alignment pin 3 sensed switch 12 inductions throw off the die sinking release.
Above content described in this specification only is to the explanation of the utility model structure example; the person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
