Abstract
The utility model discloses a fast injection oil cylinder, which comprises a main oil cylinder tube, a piston, a front end cover, a back end cover and a piston rod, wherein an oil inlet is arranged on the back end cover, an exhaust opening is arranged on the front end cover, the piston rod is a double-end piston rod, a sub oil cylinder tube is fixedly arranged on the front end cover, the diameter of the sub oil cylinder tube is smaller than the diameter of the main oil cylinder tube, the outer end of the sub oil cylinder tube is provided with a sub end cover, an oil outlet is arranged on the sub end cover, and one end of the piston rod of the double-end piston rod extends into the sub oil cylinder tube. The utility model has the advantages that the diameter of the sub oil cylinder tube is smaller than the diameter of the main oil cylinder tube, so the hydraulic oil quantity required to be discharged by the sub oil cylinder tube is less than the hydraulic oil quantity of a left cavity of the main oil cylinder tube in the prior art, the arrangement of a fast oil discharge system is not needed, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of plastic injection equipment or metal die-casting machine, especially relates to the fast injection oil cylinder of a kind of plastic injection equipment or metal die-casting machine.
Background technique
Injection machine includes parts such as injection member, matched moulds parts, hydraulic system, and the fast injection oil cylinder is the pith in the injection member.Traditional injection cylinder structure comprises cylinder body, is arranged on piston and piston rod in the cylinder body, and the bonnet of cylinder body is provided with filler opening, and the protecgulum of cylinder body is provided with oil drain out.Its working principle: when machine is in inject state, the right chamber oil-feed of oil cylinder, piston and piston rod drive screw rod and advance the outside oil extraction in left chamber of oil cylinder in this process under the pressure oil effect.In order to make the injection cylinder quick oil feeding, oil cylinder has the two-way oil inlet passage, and one the tunnel is that fuel tank passes through oil pump directly by the filler opening oil-feed, and another route accumulator is to the filler opening oil-feed.Because the oil drain quantity in chamber, an oil cylinder left side is bigger, need add a fast oil draining system, to improve the speed of oil extraction.The complex structure of fast oil draining system, cost of production is higher.
Summary of the invention
Technical problem to be solved in the utility model provides the lower fast injection oil cylinder of a kind of energy consumption.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of fast injection oil cylinder, comprise the master cylinder tube, piston, front cover, rear end cover and piston rod, it is characterized in that rear end cover is provided with filler opening, described front cover is provided with relief opening, described piston rod is two piston rods of lifting one's head, be set with the auxiliary oil cylinder tube on the front cover, the diameter of described auxiliary oil cylinder tube is less than the diameter of master cylinder tube, the outer end of described auxiliary oil cylinder tube is provided with secondary end cap, described secondary end cap is provided with oil drain out, and described two piston rods of lifting one's head piston rod stretch in the described auxiliary oil cylinder tube.
Described auxiliary oil cylinder tube is fixed on the front cover by flange.
The diameter of described auxiliary oil cylinder tube is 1:(1.5～4 than the diameter of master cylinder tube).
Compared with prior art, the utility model has the advantages that when injector enters inject state, hydraulic oil enters into the right chamber of master cylinder tube by filler opening, piston is moved to the left by the two piston rods of lifting one's head of the effect drive of hydraulic oil oil pressure, at this moment, left chamber in the master cylinder tube is by the relief opening exhausting air, discharge hydraulic oil in the oil pocket of auxiliary oil cylinder tube, because the diameter of auxiliary oil cylinder tube is less than the diameter of master cylinder tube, therefore the hydraulic pressure oil mass that need discharge of auxiliary oil cylinder tube is less than the left chamber hydraulic pressure oil mass of master cylinder tube in the prior art, just need not fast oil draining system is set, reduced the cost of producing.
When traditional fast injection oil cylinder work, because the oil drain quantity of oil cylinder is big, the oily speed ratio of hydraulic oil is very fast, can produce bigger heat, has caused the loss of energy.
Adopt two piston rods of lifting one's head simultaneously, piston is more steady when mobile in the master cylinder tube, makes the better reliability of master cylinder.
Description of drawings
Fig. 1 is fast injection cylinder structure figure in the prior art;
Fig. 2 is the configuration state figure the during oil-feed of fast injection oil cylinder in the utility model;
Fig. 3 is the configuration state figure the during oil return of fast injection oil cylinder in the utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of fast injection oil cylinder, comprise master cylinder tube 1, piston 2, front cover 3, rear end cover 4 and piston rod 5, rear end cover 4 is provided with filler opening 6, front cover 3 is provided with relief opening 7, piston rod 5 is two piston rods of lifting one's head, be set with auxiliary oil cylinder tube 8 on the front cover 3, auxiliary oil cylinder tube 8 is fixed on the front cover 3 by flange 9.The diameter of auxiliary oil cylinder tube 8 is 1:1.5 than the diameter of master cylinder tube 1, the outer end of auxiliary oil cylinder tube 8 is provided with secondary end cap 10, secondary end cap 10 is provided with oil drain out 11, two piston rods 51 of lifting one's head piston rod stretch in the auxiliary oil cylinder tube 8, and two other end piston rods 52 that go out piston rod are connected with outside screw rod.
Embodiment two: other parts are identical with embodiment one, and the diameter that its difference is auxiliary oil cylinder tube 8 is 1:2.5 than the diameter of master cylinder tube 1.
Embodiment three: other parts are identical with embodiment one, and the diameter that its difference is auxiliary oil cylinder tube 8 is 1:4 than the diameter of master cylinder tube 1.
