Description
Technical field
The present invention relates to a kind of Mode-locking oil cylinders of injection molding machine.
Background technique
Pull rod also serves as locking piston bar in existing two-plate type injection machine Mode-locking oil cylinder, and piston is directly general with tie rod end
To be threadedly coupled, wherein having common M screw thread, trapezoidal thread or special thread.
There are following deficiencies for existing threaded connection:
1, helicitic texture has higher stress to concentrate: in injection molding machine course of normal operation, each mode locking process pull rod deforms masterpiece
With being all the peak value reached after locking from mold contact start, from small to large；Die sinking process is on the contrary.It is answered by alternation in pull rod section
Power, the thread root factor of stress concentration is high, is also easy to produce fatigue rupture, leads to pull rod early fracture.It is concentrated to eliminate stress, one
As need to increase root fillet etc., but limited, improved limited by thread size.
2, screw thread bears additional bending stress: as shown in Figure 1, when injection moulding machine mode-locking, solid plate deformation causes to be mounted on
Cylinder tube in template is rotated together with piston.Because having gap between cylinder tube 2 and pull rod 1, piston 4 and pull rod 1, this
Torque has been eventually transferred on the threaded engagement face 40 of piston and pull rod, and screw thread is made additionally to bear bending stress.Threaded portion
Very big pure extension stress itself is born, in addition this bending stress, combined stress keeps the maximum tension stress of thread root aobvious
Work becomes larger, and increases a possibility that recurring structure destroys at screw thread.
3, the assembly precision of screw thread requires high: the piston of big quality, without special tooling, it is likely that send out in assembling process
Population's surface damage.
4, the accuracy of manufacture of screw thread requires high: the such as difficulty of processing such as thread form angle, pitch tolerance, central diameter size are larger, and
Small manufacturing defect often results in premature crack initiation in production process, and quality control requirement is very high, is not easy to meet.
Summary of the invention
A kind of semi-ring band brake type is provided the technical problem to be solved by the present invention is to overcome the above-mentioned insufficient of the prior art
The Mode-locking oil cylinder of connection keeps its stress uniform and small, manufactures and easy for installation.
The present invention solves the above problems used technical solution are as follows: a kind of Mode-locking oil cylinder of semi-ring band brake type connection, packet
Include pull rod, Mode-locking oil cylinder cylinder, Mode-locking oil cylinder rear cover, piston, two semi-ring nuts, locking gland；The rear cover is fixed on mode locking
Cylinder tube rear portion forms the cylinder block of Mode-locking oil cylinder；The piston is placed in Mode-locking oil cylinder tube inner chamber, and pull rod penetrates mode locking oil
Piston is passed through after cylinder barrel；Annular groove is arranged in the pull rod tail portion, and correspondingly, annular is respectively set in two semi-ring nut inner surfaces
Tooth, annular tooth can be inserted into the annular groove of pull rod and be engaged；The semi-ring nut also sets up through hole, and locking gland, which is also provided with, to be passed through
It perforates, fixing threaded hole is set on piston, locking gland, semi-ring nut are connected to by piston by screw, through hole, fixing threaded hole
On.
Preferably, groove is arranged in above-mentioned locking gland front, and the tie rod end is placed in the groove, gland locking in this way
It being capable of preferably steady brace.
Preferably, the semi-ring nut inner hole annular tooth can also be used in lance tooth, stepped tooth, saw-shaped tooth.
More specifically, the semi-ring nut inner hole annular tooth can be a tooth can also be also multiple tooth, correspondingly annular groove
It can be one or more.
Preferably, the annular groove bottom uses Rouno Cormer Pregrinding Wheel transition, particularly preferred to be more than or equal to 1/2 groove width for slot bottom fillet R,
It is remarkably decreased stress concentration.
Compared with the prior art, the advantages of the present invention are as follows:
1, the annular tooth being arranged between semi-ring nut, pull rod connects and semi-ring nut is connected on piston with locking gland, can
It is oriented to by two semi-ring nut front and back ends, influences the flank of tooth of semi-ring nut and pull rod by template deformation, only by pure extension
Power, therefore uniform force.
2, compared to screw thread, the annular groove processing of semi-ring nut is relatively easy, and when assembly need to only live semi-ring nut buckle, pacifies
Fill very convenient, surface accuracy is not also influenced by assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing injection moulding machine mode-locking oil cylinder.
Fig. 2 is the overall structure diagram of the Mode-locking oil cylinder of semi-ring band brake type of embodiment of the present invention connection.
Specific embodiment
With reference to the accompanying drawing, the present invention will be further described for embodiment.
As shown in Fig. 2, a kind of Mode-locking oil cylinder of semi-ring band brake type connection, including pull rod 1, Mode-locking oil cylinder cylinder 2, Mode-locking oil cylinder
Rear cover 3, piston 4, two semi-ring nuts 5, locking glands 6.
Annular groove 11 is arranged in above-mentioned 1 tail portion of pull rod, and correspondingly, annular tooth 51, annular is arranged in two 5 inner surfaces of semi-ring nut
Tooth 51 is inserted into the annular groove 11 of pull rod 1 and is engaged.
Above-mentioned semi-ring nut 5 also sets up through hole 53, and locking gland 6 is also provided with through hole 63, fixed spiral shell is arranged on piston 4
Locking gland 6, semi-ring nut 5 are connected to piston 4 by screw 7, through hole 63, through hole 53, fixing threaded hole 43 by hole 43
On.
Above-mentioned rear cover 3 is fixed by screws in 2 rear portion of Mode-locking oil cylinder cylinder, forms the cylinder block of Mode-locking oil cylinder.
Above-mentioned piston 4 is placed in 2 inner cavity of cylinder tube, and pull rod 1 passes through 4 middle part of piston after penetrating cylinder tube 2, by two semi-rings
The annular tooth 51 of nut 5 buckles into the annular groove 11 of 1 tail portion of pull rod, then by screw 7, locking gland 6 by two semi-ring nuts 5
It is fixed on piston 4, so that pull rod 1 is fixed on piston 4.
Further, groove 61 is arranged in above-mentioned 6 front of locking gland, and above-mentioned 1 tail end 12 of pull rod is placed in the groove 61,
Gland 6 locking in this way being capable of preferably steady brace 1.
Annular tooth in the present embodiment has 6, or one or other quantity.
Above-mentioned 11 bottom of annular groove is more than or equal to the Rouno Cormer Pregrinding Wheel transition of 1/2 groove width using slot bottom fillet R, concentrates stress significant
Decline.
When above-mentioned Mode-locking oil cylinder works, the tooth that oil cylinder cavity pressure connect semi-ring nut 5 with pull rod 1 bears axial carry
Lotus, semi-ring nut front end, the inner hole of rear end and pull rod have guiding, by the torque that template deformation is influenced and is generated on piston, most
It is transmitted on pull rod by nut front and back ends guide section, rather than is transmitted on pull rod by the nut interior flank of tooth eventually, make the flank of tooth
Only by pure extension state, uniform force.
