Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
In the specific implementation, a kind of new and effective extruder, including extrusion cabin 1, the extrusion cabin 1 are used to incite somebody to action the present invention
Molten aluminum is extruded, and strengthens the mechanical property of molten aluminum, and inlet 2, the inlet 2 are connected with the extrusion cabin 1
On be connected with molten aluminum pond 3, the extrusion cabin 1 is equipped with top board 4 and lower platen 5, is connected with the top board 4
Venthole 6, the venthole 6 are equipped with liquid level gauge 7, and the liquid level gauge 7 is used to detect aluminium liquid height in venthole 6, institute
Hydraulic cylinder, the top board 4 and lower platen 5 are connected with the top board 4 and lower platen 5 stated by hydraulic feed by molten aluminum
Extrusion, the inlet 2 is equipped with check valve, is connected with extrusion 8 in the extrusion cabin 1, on the extrusion 8
Temperature detector 9 is connected with, water cooling tube 10, the water cooling tube 10 connection cistern, the storage are additionally provided with extrusion 8
Entrance and exit is equipped with pond, the top of extrusion 8 is equipped with sprinkler head 11, connects and set on the sprinkler head 11
There are switch, switch connection temperature detector 9, the temperature detector 9 will be opened when temperature is excessive and switched.
The molten aluminum pond 3 is equipped with smelting furnace, and the molten aluminum of thawing is added molten aluminum pond 3 by the smelting furnace, keeps molten aluminum pond 3
