[0002] Aluminum profile extrusion utilizes the plasticity of aluminum. Under the action of an extruder, an aluminum ingot is placed into the extrusion cylinder of the extruder, and pressure is applied through the extrusion rod to cause the aluminum ingot to undergo plastic deformation and be extruded from the die hole of the extrusion die to form an aluminum profile with specific shape, size and properties.

[0027] Specifically, the spraying assembly 7 comprises a mounting ring 71, a water pump 73 and a liquid outlet pipe 77, the water pump 73 is installed in the bottom end of the inner cavity of the fixed seat 5, and the input end of the water pump 73 extends into the inner cavity of the liquid storage tank 1;

[0028] The mounting ring 71 is welded in the middle part of the inner cavity of the fixed seat 5, the top end of the mounting ring 71 is provided with a connecting table 72, the middle part of the top end of the connecting table 72 is provided with an extrusion groove 74, and one side of the connecting table 72 away from the middle part is provided with a liquid storage groove 742, and the inner cavity of the liquid storage groove 742 is communicated with the extrusion groove 74;

[0029] The bottom end of the connecting table 72 is provided with a gas guide cylinder 75, the upper end of the gas guide cylinder 75 is communicated with the inner cavity of the extrusion groove 74, the upper end of the gas guide cylinder 75 is fixedly provided with a stop ring 751, the inner cavity of the stop ring 751 is slidably provided with a sleeve 752, and the bottom end of the sleeve 752 is fixedly provided with a piston 753 which is slidably arranged on the inner cavity surface of the gas guide cylinder 75;
