Abstract
The utility model relates to a double output shaft energy saving injection oil cylinder for an injection moulding machine, which is formed by that a piston rod and a piston are fixedly connected into a whole which is matched with a cylinder barrel with a sealing ring, one end of the cylinder barrel is fixedly connected with a cylinder front cover with a front press cover, and the piston rod is matched with the inner hole of a front copper sleeve. Both ends of the piston rod are respectively provided with an extending shaft. Furthermore, one end of the piston rod is provided with a large shaft, and the other end of the piston rod is provided with a small shaft. The other end of the cylinder barrel is also fixed with a cylinder rear cover with a rear press cover. The large shaft end of the piston rod is matched with the inner hole of a rear copper sleeve. Because the piston rod is provided with double output shafts, the two edges of the piston rod have the functions of supporting and guiding, which overcomes the contact deflection in moving and reduces the friction. With stable work and long service life, the utility model can adjust the injecting rate. In the process of injecting, the back pressure is small, and the pressure loss is decreased by 30%. The utility model can save energy and enhance the injecting rate.
Description
The utility model relates to a kind of key components and parts of injection machine, particularly a kind ofly can improve injection rate, shorten molding cycle, save the energy, improve the quality of products, can satisfy the high pressure fast injection, press the two energy-conservation injection cylinders of shaft of injection machine of rapid shaping needs in satisfying again.
The injection machine of existing all types of, specification, all adopt single-piston rod injection cylinder structure, its injection pressure loss is bigger, lost certain energy, thereby reduced injection rate, do not satisfy user's request, thereby directly restricted, influenced quality, production efficiency and the economic benefit of manufacturer's plastic products.
The purpose of this utility model is to provide a kind of injection machine two energy-conservation injection cylinders of shaft, can save the energy, improve the service life of injection rate and parts, and improve the performance and the quality of injection machine.
The utility model is achieved in that the two energy-conservation injection cylinders of shaft of injection machine, be fixedly connected into integral body by piston rod and piston, cooperate with the cylinder barrel of band sealing ring, cylinder barrel one end is fixedly connected with the cylinder front cover of gland before the band, and piston rod cooperate with preceding copper sheathing endoporus form, all there is projecting shaft at described piston rod two ends, and one end be macro-axis, one end is little axle, and the end in addition of cylinder barrel also is fixed with the cylinder bonnet of band rear pressing cover, and the big axle head of piston rod cooperates with back copper sheathing endoporus.
Accompanying drawing. structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Piston rod (6) all has the projecting shaft structure for two ends, and an end diameter is macro-axis D greatly
1, an end is little axle D
2
Have screw thread to be connected with piston rod (6) in the piston (5), and fix with locking pad volume, round nut, prevent that piston (5) is loosening, piston (5) is outer to have the sealing volume to be sealed and matched with cylinder barrel (7).
Cylinder front cover (8), one end of cylinder bonnet (4) is separately fixed on the two ends of cylinder barrel (7), end is equipped with the preceding copper sheathing (9) of band sealing ring and anti-dust devil in addition, back copper sheathing (3), and before making, back copper sheathing (9), (3) endoporus is little with piston rod (6) respectively, macro-axis movingly, before, rear pressing cover (10), (2) be screwed in cylinder front cover (8), on the end face of cylinder bonnet (4), before pushing down, back steel bushing (9), (3) can not go here and there, piston rod cover (1) is screwed on rear pressing cover (2), prevent that piston rod (6) is contaminated, the energy-conservation injection cylinder of two shafts is assembled into.
During use, the same with prior art single-piston rod injection cylinder, two injection cylinders are parallel, and symmetry is placed, and makes the little axle head D of piston rod (6)
2With penetrate platform after plate be connected, connecting the injection screw rod behind the platform in the middle of the plate and penetrate.During injection, two group oil cylinders simultaneously advance pressure oil, the oil return of B chamber in the A chamber, and piston rod (6) is moved to the left under the pressure oil effect like this, drive to penetrate the injection screw in the middle of the plate behind the platform, also are moved to the left simultaneously, owing to left end piston rod (6) diameter D
1Bigger, make B chamber volume reducing, so piston rod (6) when moving left, B chamber resistance very little (back pressure) has then improved injection power, has saved the energy, at this moment just can high injection pressure, the fastest injection speed is injected.
If pressure oil is advanced in A chamber, B chamber in two group oil cylinders simultaneously, because of piston rod (6) D
1Go out shaft diameter greater than D
2Go out shaft diameter, so A chamber piston (5) lifting surface area is greater than B chamber piston (5) lifting surface area, therefore A chamber piston (5) thrust is greater than B chamber piston thrust, its thrust equals 2 times of the products that the piston lifting surface area in A chamber deducts B chamber piston lifting surface area and input pressure, so piston rod (6) is toward moving left, oil oil sump tank not in B chamber when mobile, pass through solenoid control, B chamber and A chamber are connected, increased the flow of A chamber oil, it can faster speed be injected, thereby realized middlely to press fast injection, improve injection rate, shortened molding cycle.
The utility model compared with prior art, because there are two shafts at the piston rod two ends, both sides are with forward and backward The cylinder front/rear cover of copper sheathing is made supporting and guiding, has overcome the contact deflection between the motion, and stable working subtracts Lack frictional resistance, improved the service life of part, solved the piston rod oil leakage phenomenon that brings easy to wear, Thereby improved the Performance and quality of injection machine. Can want according to complexity and the moulding of plastic products shape again Ask decide in the employing press, high speed injection, or high pressure, middling speed injection, it is diligent to have increased making of injection machine Can, can carry out injection rate and regulate, because of two shaft injection cylinders, back pressure is little during injection, the pressure loss is little again (can reduce by 30%) improved injection rate, thereby saves the energy.
