[0002] At present, in the production process of profile processing of existing aluminum profile extrusion machines, the extruders can produce various profiles, and various profiles are extruded and produced through different dies. Since the extrusion force on the die is large, in order to firmly fix the die, most extruders have more die fixing parts. When production needs to change to another profile, the die fixing parts on the mounting base are manually disassembled, the original die is taken out, and a new die is replaced. The die replacement is relatively complicated and the operation time is long, which affects normal production. In view of the above reasons, a quick die changing device and a use method of an aluminum profile extrusion molding machine are proposed. Summary of the Invention

A driven gear is provided at the upper end of the gripper rotating clamp, a clamp rotating motor is provided on one side of the lower end of the lever, and a driving gear is provided at the lower end of the clamp rotating motor. The driving gear and the driven gear are correspondingly engaged to form a pair of gears.

[0008] On the other hand, the present invention provides a method for using a quick mold changing device of an aluminum profile extrusion molding machine: during production, the barrel is manually filled with blanks. After the blanks are filled, when the produced profile needs to install the first spare mold, the slider moves to the top of the first spare mold that needs to be used and stops. Two pairs of levers are controlled by two pairs of cylinders to drive the gripper to rotate the chuck and move downward synchronously to grab the first spare mold.
