Abstract
The utility model provides a piston rod anti-loose device for an injection molding machine. The piston rod anti-loose device for the injection molding machine comprises a mold locking piston rod and a thrust base, and further comprises a mold locking nut and a stop screw, wherein the mold locking piston rod is sleeved with the thrust base. The rear end face of the mold locking nut is sealed, and a large threaded hole is formed in the front end face of the mold locking nut. The mold locking nut is in threaded connection at the end portion of the mold locking piston rod. The front end face of the mold locking nut abuts against the thrust base. A small threaded hole is formed in the rear end of the mold locking nut. The stop screw is installed inside the small threaded hole in a matched mode. The head of the stop screw extends into the large threaded hole and abuts against the end face of the mold locking piston rod. According to the piston rod anti-loose device for the injection molding machine, the rigid performance and strength of the mold locking piston rod are fully ensured, the service life is prolonged, the higher mechanism price ratio is achieved, and assembly, disassembly and adjustment are convenient and rapid.
Description
Technical field
The utility model relates to a kind of injection machine, particularly a kind of injection machine piston rod locking device.
Background technology
Mechanical reaming type injection machine, in die open/close movement process, has had requirement to bearing the intermediate connecting part locking piston bar anti-loose structure of enlarger.The limitation of existing piston rod locking gear has displayed.Traditional piston rod retention mechanism is adopt to adopt thrust bearing to add stop washer, hold-down nut, and this structure reality arranges locking with actual piston bar and thrust bearing of stop washer on piston rod binding, by hold-down nut, locates stop washer.Owing to need to adding groove at piston rod, the smallest base footpath that has dwindled locking piston bar may cause rod fracture in matched moulds.

The technical problems to be solved in the utility model is to provide that a kind of structural strength is high, good rigidly, and the piston rod locking device of injection machine efficiently easy to adjust is installed.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of injection machine piston rod locking device, comprise locking piston bar 1 and be set in the thrust bearing 2 on described locking piston bar 1, also comprise locked mode nut 3 and backing-up screw 5, rear end face sealing and the front end face of described locked mode nut 3 offer major thread hole, described locked mode nut 3 is threaded connection the end at described locking piston bar 1, and the front end face of described locked mode nut 3 props up described thrust bearing 2, the rear end of described locked mode nut 3 offers minor thread hole, described backing-up screw 5 cooperations are arranged in described minor thread hole, and the head of described backing-up screw 5 extends in described major thread hole and props up the end face of described locking piston bar 1.
Further, described backing-up screw 5 is provided with stop nut 4, the rear end face laminating of the front end face of described stop nut 4 and described locked mode nut 3.
Further, described minor thread hole is at least three and circumferentially uniform along axis.
(3) beneficial effect
The utility model injection machine piston rod locking device, the mode of employing screw fastening, makes trip bolt bear in the course of the work normal pressure, has fully guaranteed rigidity energy and the intensity of locking piston bar, has extended service life, has realized higher mechanism's valency ratio; And installation, dismounting and easy to adjust quick.
Accompanying drawing explanation
Fig. 1 is the structural representation of piston rod locking device for the utility model injection machine.
The specific embodiment
Consult Fig. 1, the utility model provides a kind of injection machine piston rod locking device, comprise locking piston bar 1 and be set in the thrust bearing 2 on this locking piston bar 1, also comprise locked mode nut 3 and backing-up screw 5, rear end face sealing and the front end face of locked mode nut 3 offer major thread hole, locked mode nut 3 is threaded connection the end at locking piston bar 1, and the front end face of locked mode nut 3 props up thrust bearing 2, in the rear end of locked mode nut 3, offer minor thread hole, backing-up screw 5 cooperations are arranged in this minor thread hole, the head of while backing-up screw 5 extends in major thread hole and props up the end face of locking piston bar 1, in order further to improve coupling mechanism force, on backing-up screw 5, be provided with stop nut 4, the rear end face laminating of the front end face of this stop nut 4 and locked mode nut 3, in the present embodiment, minor thread hole is at least three and circumferentially uniform along axis, preferably three.
The utility model injection machine piston rod locking device, the mode of employing screw fastening, makes trip bolt bear in the course of the work normal pressure, has fully guaranteed rigidity energy and the intensity of locking piston bar, has extended service life, has realized higher mechanism's valency ratio; And installation, dismounting and easy to adjust quick.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
