Specific embodiment
How casting level is effectively improved.
In view of the above technical problems, by the analysis to reason, knotting furnace formula low pressure is cast in constantly research discovery to inventor
The machine of making is simplified into device shown in FIG. 1, and the upper surface of the device has workbench 5, has casting mold 6 (to can be sand mold, stone on workbench
Paste type, hot investment casting type, ceramic mould are also possible to complicated metal mold), there is stalk 15 in holding furnace 4, have check valve under it
14, there are solenoid valve 11 and air inlet 9, compression chamber 10, electrode 7 thereon.The control system when the solenoid valve 11 in compression chamber 10 is opened
Argon gas is sent into compression chamber 10 through air inlet 9 by system.Aluminium alloy is filled in casting mold under the driving of pressure, when type chamber is full of
High pressure gas is sent compression chamber that semisolid molten aluminum is forced to get into type by control system immediately according to the anomalous variation of pressure in sensor
The feeding to casting is completed in chamber.It allows air inlet 9 and atmosphere to connect when semi-solid-state metal solidification, simultaneously closes off solenoid valve 11.
Casting mold is taken out, casting is cleaned out, just completes first casting forming work of semisolid.Due to the reduction of compression chamber's molten aluminum, liquid
Check valve is opened than low in furnace, by this liquid level difference in position, the aluminum water in furnace is supplemented into compression chamber thus and can produce the 2nd,
3..........Due in furnace liquid level to reduce the indoor aluminum water of pressurizeing fewer and fewer therefore can only produce smallclothes.It is big in order to solve
The semi-solid-state shaping problem of part must make compression chamber fill aluminum water every time, thus in 10 upper ends electrode 7 of compression chamber, every life
After producing one, control system applies several seconds negative pressure in air inlet 9 and molten aluminum is sucked the stopping when liquid level encounters electrode 7 of compression chamber 10
Pumping switchs to produce next casting, this not only solves the production of big part and improves the utilization rate of aluminum water.
