Fig. 3 is top view of the present utility model；
Fig. 4 is the state diagram of the utility model casting machine either on or off.
Embodiment
Technical solutions of the utility model are described in detail below by accompanying drawing.
Embodiment 1：Magnesium alloy low-pressure die-casting machine as shown in Figure 1 to Figure 3, including the casting on same ground 6
Machine 1, electric cabinet 4, hydraulic power unit 3, protection air pressure control cabinet 5 and the holding furnace 2 located at melt pit 7；Casting machine 1 includes workbench
Face, top plate, the movable plate located at work top top and both sides, the casting folding that movable plate is responsible for mould is used, in order to completely cut off
The purpose of air, installs the semitight outer cover with sealing joint strip around work top, and is 1.38 than air using argon gas
The characteristics of proportion, argon gas gas outlet 11 is installed in both sides, make argon gas under outer cover closed mode by lower from upper full full of whole
Inside outer cover so that the magnesium alloy subsequently in casting process is all in the encirclement of argon gas, and the magnesium alloy of fusing was being cast
In journey all the time can not and air contact, would not burn, can normally cast in a mold, until casting be molded take out.
Main control device in electric cabinet 4 is the electric-control system of all parts, includes the temperature control of holding furnace 2, hydraulic pump
Stand 3 supporting magnetic valve folding controls, the source of the gas folding control of the casting air pressure inside air pressure Confucius's case, using man-machine interface
Touch-screen coordinates the intelligent control of each component actuation of industrial programmable controller progress and casting process；
Each hydraulic cylinder in the connecting working table face of hydraulic power unit 3, is driven by magnetic valve come the folding to each hydraulic cylinder；
Crucible is provided with holding furnace 2, crucible is sealed by crucible cover, and argon gas can be passed through in crucible；Protect air pressure control
The major control holding furnace 2 of case 5 and casting machine 1 processed are in the control of the protective gas needed for casting process, and its air intake connects pressure
Contracting argon gas bucket, the solenoid valve control controlled by pressure-reducing valve and electric cabinet 4 is pressurizeed and casting machine 1 to holding furnace 2 respectively
Deflation protection.
The course of work is as follows：
1st, crucible is placed in holding furnace 2 and heated, reached after holding temperature, lead to upper argon gas, sealing melting furnace is melted
Magnesium alloy liquation filled by insulating tube in the crucible in holding furnace 2, then cover sealed crucible lid, for casting do standard
It is standby；
2nd, by the mould installion of required casting on the work top of casting machine 1, and the liter liquid mouthful of holding furnace 2 is connected to
The cast gate of mould, and mould is preheated, it is ready for casting；
3rd, as shown in figure 4, under the control of electric cabinet 4, the argon gas closed above the board cleaning door of casting machine 1, board goes out
