Description
Technical field
The present invention relates to a kind of injection moulding machine mode-locking oil cylinder, in particular to a kind of two-plate type injection machine Mode-locking oil cylinder.
Background technique
General pull rod also serves as locking piston bar in two-plate type injection machine Mode-locking oil cylinder, and piston is directly connected with tie rod end
It connects.The piston of injection moulding machine mode-locking oil cylinder generally has following three kinds of forms: 1. piston rod one-piece pistons as shown in Figure 1；2. such as
Nut one-piece piston shown in Fig. 2；3. piston, nut Split piston, i.e., free-standing piston.These three pistons are in difference
Injection molding machine has application.
Though piston rod one-piece piston is easy to process, assembly is simple, and structure is safe and reliable, its cost can be very high.
Nut one-piece piston advantage is similar to piston rod one-piece piston, but since nut couples with piston rod thread, by
Power is uneven, and nut stress can be amplified under specific circumstances, and the helicitic texture for causing piston rod and nut to cooperate is broken
It is bad.
Piston, nut Split piston, though without limitation on the material of piston rod and nut, moderate cost, due to nut
Same as piston rod is to be threadedly coupled, and therefore, the shortcomings that threaded connection still has.
Summary of the invention
A kind of injection moulding machine mode-locking is provided the technical problem to be solved by the present invention is to overcome the above-mentioned insufficient of the prior art
The piston of oil cylinder and pull rod bindiny mechanism, make its at low cost, piston rod and nut uniform force.
The present invention correspondingly provides a kind of injection moulding machine mode-locking oil cylinder, makes its at low cost, piston rod and nut uniform force.
The present invention solves the above problems used technical solution are as follows: a kind of piston of injection moulding machine mode-locking oil cylinder and pull rod connect
Connection mechanism, including locking piston bar, locking piston, mode locking nut, built-up piston compacting ring；The locking piston penetrates mode locking
It is limited in piston rod, on the left of locking piston by locking piston bar, right side is fixed by the nut for fixing on the piston rod, locking piston
Centre setting groove, forms the cavity for accommodating built-up piston compacting ring between groove and piston rod；The built-up piston pressure
Collar is placed in cavity and by locking piston and lock piston rod lock.
Preferably, the built-up piston compacting ring includes left piston compacting ring, right piston compacting ring, outer piston compression
Circle, four part of inner piston compacting ring, left piston compacting ring left side are adjacent on the right side of locking piston, and lock is close on the outside of outer piston compacting ring
On the inside of mould piston, locking piston bar, left piston compacting ring, right piston compacting ring, outer piston pressure are close on the inside of inner piston compacting ring
It is close together on the inside of collar, inner piston compacting ring, is easier to offset torque inside locking piston in this way.
Preferably, above-mentioned left piston compacting ring, right piston compacting ring, outer piston compacting ring, inner piston compacting ring two-by-two it
Between combined by inclined-plane cooperation, be easy to install in this way, and be easier to clamping piston bar.
Preferably, it is fixed between above-mentioned left piston compacting ring and right piston compacting ring by screw, it in this way can be preferably
It is fixed.
Also provide a kind of injection moulding machine mode-locking oil cylinder comprising above-mentioned piston and pull rod bindiny mechanism, piston are placed in mode locking oil
In cylinder barrel.
Compared with the prior art, the advantages of the present invention are as follows: made between pull rod and piston by built-up piston compacting ring
Fixation it is more convenient, it is relatively low compared to one-piece piston bar cost；Compared to nut one-piece piston structure and former piston, spiral shell
Female split type structure is more safe and reliable, greatly reduces the piston generated by solid plate deformation and piston rod thread structure is broken
Bad a possibility that.

Specific embodiment
With reference to the accompanying drawing, the present invention will be further described for embodiment.
As shown in Fig. 4, Fig. 5, Fig. 6, a kind of injection moulding machine mode-locking oil cylinder comprising piston and pull rod bindiny mechanism, mode locking oil
Cylinder barrel 2, piston and pull rod bindiny mechanism include locking piston bar 1, locking piston 7, mode locking nut 8, built-up piston compacting ring.
Above-mentioned locking piston 7 is placed in the inner cavity of Mode-locking oil cylinder cylinder 2, and locking piston bar 1 penetrates in Mode-locking oil cylinder cylinder 2, lock
Mould piston 7 penetrates in locking piston bar 1, and left side leans against in the piston shoulder 12 on locking piston bar 1 and by its limit, and right side is set
It sets groove 72 and forms cavity between piston rod 1, built-up piston compacting ring is placed in the cavity and locks piston rod 1.
Said combination formula piston compacting ring includes: left piston compacting ring 3, right piston compacting ring 6, outer piston compacting ring 4, interior
Piston compacting ring 5, left piston compacting ring 3, right piston compacting ring 6, outer piston compacting ring 4, inner piston compacting ring 5 are superimposed on one
It rises, is placed in the cavity between locking piston 7 and locking piston pull rod 1.
Above-mentioned left piston compacting ring 3 is packed into locking piston, against the compacting ring mounting surface of locking piston, inner piston compacting ring
5 are packed into piston, cooperate with left piston compacting ring 3；Outer piston compacting ring 4 is packed into piston, cooperates with left piston compacting ring 3；Right work
It fills in compacting ring 6 and is packed into piston, cooperate with inner piston compacting ring 5 and outer piston compacting ring 4, the right side of right compacting ring 6 and piston
Right side flushes.
In the present embodiment, screw hole 31 is set, and ramp 32, lower inclined plane is respectively set in two sides on above-mentioned left piston compacting ring 3
33, ramp 62, lower inclined plane 63 is respectively set in right piston compacting ring 6, and through hole 61 corresponding with screw hole 31 is arranged；Outer piston
Left tilted surface 42, right tilted surface 43 is arranged in compacting ring 4, and left tilted surface 52, right tilted surface 53 is arranged in inner piston compacting ring 5.
Above-mentioned left piston compacting ring 3, right piston compacting ring 6, outer piston compacting ring 4, inner piston compacting ring 5 divide between any two
Not Tong Guo the cooperation of above-mentioned inclined-plane combine, cooperation in this way is more preferable, piston and piston rod with lock more preferably.
Above-mentioned screw 10 passes through the through hole 61 of right piston compacting ring 6, screws in 3 screw hole 31 of left piston compacting ring, makes a left side
Piston compacting ring 3 and right piston compacting ring 6 connect, and apply certain screw-down torque, to make outer piston compacting ring 4 and inner piston
Compacting ring 5 respectively with piston and piston rod swelling.
Screw thread 11 is arranged in above-mentioned 1 tail portion of locking piston bar, correspondingly, setting in the intermediate through hole 24 of above-mentioned mode locking nut 8
The screw thread 81 being adapted with screw thread 11, mode locking nut 8 are securely screwed together with 1 tail portion of pull rod, 8 left side of mode locking nut
It is tightly attached on 7 right side of locking piston.
In use, since the inclination of minute angle can occur for fixed die plate of injection molding machine deformation cylinder tube, cylinder tube inner wall at this time
With piston contact, apply a pair of of couple Fa on piston.Since piston and piston rod are fitted close, gap is not present, can be considered
One, this couple can be converted into moment of resistance M1 and M2 between piston and piston rod, not influence the cooperation of nut and piston rod, spiral shell
Female screw thread at piston rod cooperation only by responsive to axial force, is in pure extension state, keeps structure at screw thread more safe and reliable,
See Fig. 4.
