Mouthful, demarcation strip is equipped with the second hydraulic fluid port and third hydraulic fluid port for being respectively communicated with the first oil cylinder cavity and the second oil cylinder cavity, the second oil
Mouth passes through the diameter along demarcation strip by radial the first oil cylinder of oil communication then axially extended along demarcation strip, third hydraulic fluid port
To the second oil cylinder of oil communication then axially extended, the second hydraulic fluid port and third hydraulic fluid port are located at same circumferential plane.
Further, the first hydraulic fluid port is located on the protecgulum of the second oil cylinder, and the 4th hydraulic fluid port covers after being located at the first oil cylinder.
The utility model has the beneficial effects that：This programme realizes the extruding to liquid aluminium, the first oil by double cylinder structures
Cylinder and the second oil cylinder cooperation secondary extrusion make the stomata of metal inside of extrusion forming, shrinkage cavity and it is loose the defects of it is less and
Dense structure.Pair the 4th hydraulic fluid port refuels when initial, and First piston bar pushes second piston bar advance to squeeze liquid aluminium for the first time
Pressure waits for liquid aluminium cooling to a certain extent, refuels to third hydraulic fluid port, the second oil cylinder moves on squeezes liquid aluminium again
Pressure twice refuels to the first hydraulic fluid port and the second hydraulic fluid port after the completion of pressing steps, and First piston bar and second piston bar are return back to just
Beginning position.
