Description
Technical field
The invention belongs to Die-casting Machines apparatus field, particularly a kind of die casting machine boost-up circuit hydraulic system.
Background technique
In die castings production process, after fast shot terminates, before molten metal solidifies, high pressure compression is carried out to die castings, object Shi Shi die castings dense structure, reduce subsurface defect.This high pressure compression action provides boost pressure to carry out compacting die castings by pressurizing cylinder.There is provided boost pressure must set up supercharging campaign before metal freezing, otherwise greatly will affect pressurized effect, this just needs minimizing to build the pressure time, builds the speed of response of pressure time representation boost pressure.Build the important indicator that the pressure time is reflection die casting machine performance, the pressure time of building of die casting machine is more short better theoretically.Chinese patent literature CN201735759U disclosed a kind of integrated injection device of cold chamber die-casting machine for 02 month 09 day in 2011, this device is provided with an injection oil circuit body, injection oil duct and supercharging oil duct is respectively equipped with the top of the main oil gallery of injection oil circuit body, injection oil duct communicates with injection oil circuit body main oil gallery, and supercharging oil duct communicates with pressurizing cylinder interior edge face; Press-shoot energy accumulator is also contained in the jointing of injection oil circuit body upper part injection oil duct and supercharging oil duct respectively with supercharging accumulator; Injection oil circuit body front end is installed and is fixed an injection oil cylinder, in injection oil cylinder, shot piston is housed, pressurizing cylinder built with charged piston, in the cylinder holes that charged piston two ends are contained in injection oil cylinder respectively and injection oil circuit body main oil gallery.Comprise injection device, dnockout arrangements for speed regulation, tup clamping and supercharging device.There is the problem of building pressure time length in this structure, therefore, is necessary to make further improvements.
Summary of the invention
Object of the present invention aim to provide a kind of simple and reasonable, accelerate boost pressure speed of response, shorten the die casting machine boost-up circuit hydraulic system of building the pressure time, to overcome deficiency of the prior art.
By a kind of die casting machine boost-up circuit hydraulic system that this object designs, comprise pressurizing cylinder, characterized by further comprising proportional flow control valve, A mouth and the B mouth of described proportional flow control valve are connected back cavity and the accumulator of pressurizing cylinder respectively, and the ante-chamber of pressurizing cylinder is connected with pressure gauge, electromagnetic direction valve, two-way plug-in valve, one-way valve and stop valve; Wherein, the A mouth of electromagnetic direction valve connects the control chamber of two-way plug-in valve.
Described electromagnetic direction valve is the electromagnetic direction valve of belt spool monitoring, and for monitoring electromagnetic direction valve valve element position, die casting machine control system monitors electromagnetic direction valve spool and is not in right position, does not perform injection action and pressurizing action, plays safety protection effect.
Described stop valve is hand stop valve, for manually bleeding off the pressure oil of the ante-chamber of pressurizing cylinder.
Advantage of the present invention and beneficial effect are: after die casting machine pressurizing action starts, two-way plug-in valve spool is pressurized oil cylinder ante-chamber and suppresses the pressure oil being in system pressure and back down fast, the fluid of pressurizing cylinder ante-chamber is drained fast, charged piston is able to quick forward motion, reduce and build the pressure time, the boost performance of die casting machine is promoted.It has simple and reasonable, accelerate boost pressure speed of response, shorten the feature of building the pressure time.
Accompanying drawing explanation
Fig. 1 is the oil circuit figure of one embodiment of the invention boost-up circuit hydraulic system.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
See Fig. 1, this die casting machine boost-up circuit hydraulic system, comprise pressurizing cylinder and proportional flow control valve 1, A mouth and the B mouth of proportional flow control valve 1 are connected back cavity 4 and the accumulator 2 of pressurizing cylinder respectively, in addition, the ante-chamber 3 of pressurizing cylinder is connected with pressure gauge 5, electromagnetic direction valve 6, two-way plug-in valve 7, one-way valve 8 and stop valve 9, and wherein the A mouth of electromagnetic direction valve 6 connects the control chamber of two-way plug-in valve 7.
Specifically, the electromagnetic direction valve that electromagnetic direction valve 6 is monitored for belt spool, for monitoring electromagnetic direction valve 6 valve element position; when electromagnetic direction valve 6 spool is not in right position; proportional flow control valve 1 does not allow to open, and does not perform injection action and pressurizing action, plays safety protection effect.
Stop valve 9 is hand stop valve, for manually bleeding off the pressure oil of the ante-chamber 3 of pressurizing cylinder.
Its working principle is: before injection action starts, whether die casting machine control system monitoring electromagnetic direction valve 6 valve element position is in right position, as electromagnetic direction valve 6 valve element position is not in right position, die casting machine control system sends alarm signal, and die casting machine stops action below; When monitoring electromagnetic direction valve 6 valve element position and being in right position, die casting machine control system performs back hammer action, pressure oil enters the ante-chamber 3 of pressurizing cylinder by one-way valve 9, the ante-chamber 3 of pressurizing cylinder suppresses the pressure oil being in system pressure, after returning hammer release, die casting machine control system control ratio Flow valve 1 is opened, and the pressure oil passing ratio Flow valve 1 of accumulator 2 enters pressurizing cylinder back cavity 4, before whole injection release, proportional flow control valve 1 remains on opening state always.After die casting machine fast shot completes, die casting machine control system performs pressurizing action, electromagnetic direction valve 6 obtains electric, two-way plug-in valve 7 control chamber leads to fuel tank, the spool of two-way plug-in valve 7 is opened fast under the effect of the pressure oil of pressurizing cylinder ante-chamber 3, the fluid of pressurizing cylinder ante-chamber 3 flows to fuel tank by two-way plug-in valve 7, and charged piston moves forward, completes pressurizing action.When pressurizing cylinder ante-chamber 3 has suppressed pressure oil, but two-way plug-in valve 7 can not be opened, when causing the pressure oil of pressurizing cylinder ante-chamber 3 to discharge, by manual unlocking stop valve 9 because of fault, the pressure oil of pressurizing cylinder ante-chamber 3 is released, is beneficial to follow-up maintenance work.
Above-mentioned is preferred version of the present invention, and those of ordinary skill in the art, to its simple modification or transformation, all drop within protection scope of the present invention.
