Injection pressure charging system, is the important component for determining die casting machine die-cast product performance, and current tradition die casting machine is substantially
Using：1, three-level injection (injection, fast shot, supercharging), maximum injection speed ≤3m/s or so；2, single loop hydraulic system
(injection, supercharging shares same oil circuit, and in production, fault rate is high, and speed is slow).Particularly die casting needs the production of anodic oxidation
Product, due to its poor fluidity, are difficult die cast, percent defective is high.Simultaneously solid shot piston, solid supercharging are used in structure
Piston rod, machining accuracy and installation accuracy require high, due to being solid piston bar, easily produce at work injection Su Du≤
Pressure Shi Jian≤30m/s is built in 3m/s, supercharging, the low speed injection almost unfavorable factor such as not.
The content of the invention
It is to be solved by this invention be traditional die casting machine when die casting needs the product of anodic oxidation, solution easily there is tortoise
Split, the quality problems such as stomata, material are loose, fault rate during reduction production improves injection pumping rate.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of energy-saving and high-speed injection pressure charging system, including the first accumulator, the second accumulator, first accumulator,
Two accumulators are connected with pressurized cylinder, shot sleeve one end and provide power, the pressurized cylinder, injection for pressurized cylinder, shot sleeve respectively
Cylinder arranges that shot sleeve sets portal frame close to pressurized cylinder one end, and supercharging piston rod, shot piston are put respectively along same horizontal line
In in pressurized cylinder, shot sleeve, supercharging piston rod one end is connected with charged piston, the other end and the floating piston in shot sleeve
Connection, shot piston connects shot piston towards described floating piston one end, and the other end is towards injection rod one end, and injection rod is another
One end connection injection plunger is placed in injection chamber, and injection chamber is fixed in quiet template, and quiet template is connected by connecting rod with portal frame.
The supercharging piston rod, shot piston are hollow piston rod, solid shot piston and solid charged piston
Bar all makes hollow piston rod into, and it is slow thoroughly to solve injection speed, is pressurized unstable, builds that the pressure time is long, assembling decentraction etc. is no
Sharp factor.
The shot sleeve is connected close to injection rod one end by fast-discharge valve plate with oil return pipe one end, and the oil return pipe other end is with returning
Fuel tank is connected, and pressurized cylinder is connected by bend pipe with oil return pipe, and the oil body produced in pressurized cylinder, shot sleeve is entered back by oil return pipe
Oil body is sent into pressurized cylinder and enters shot sleeve by fuel tank, oil return box by motor.
First accumulator, the second accumulator are piston accumulator.
The shot piston is socketed injection cushion collar close to shot piston one end, by the injection cushion collar to injection
Piston enters row buffering.
The pressurized cylinder lower end is connected with lift cylinders, is easy to change mould.
Beneficial effects of the present invention are：Control quick injection and injection to be pressurized respectively with two accumulators, take open type
Oil return, fully phases out booster back pressure, and the regulation of boost pressure is realized by adjusting energy storage pressure, and this injection system is permitted
Perhaps portion adjusts die-casting technological parameter within a large range, for various different casting, can select preferably extrusion process pressure
Superior performance, maximum injection Su Du≤9m/s are penetrated, pressure Shi Jian≤14m/s, low speed injection speed 0.05-8m/s is built in supercharging, efficiently
45%-60% is saved, injection supercharging uses double loop hydraulic system, pressure x velocity and pressure point Multistage Control, and independent is quick
And supercharging accumulator, the two kinds of supercharging triggering modes in position and pressure, more complicated technological requirement is disclosure satisfy that, according to technique needs
Tunable performance curve, lifelong zero failure is simple to operate, easily assembling.
