6. A processing method of a hollow aluminum profile processing die is characterized by comprising the following steps of: the hollow aluminum profile processing mold as claimed in claim 5, comprising the steps of:
s1): selecting a corresponding core mold (11) according to processing requirements, then assembling the core mold (11) and a mold base (12) through clamping connection of a positioning groove (19) and a fastener (15), and then closing a mold, wherein the mold base (12) seals the opening of the mold (2), the core mold (11) is positioned in the mold (2), after closing the mold, aluminum water is injected into a cavity formed between the core mold (11) and the mold (2) through a pouring pipe (16), and after the pouring is completed, cooling and molding are performed, wherein the cooling and molding process comprises the following steps: the refrigerator (101) conveys cooling water into the spiral cooling channel (103) through the guide pipe (102), and the cooling water transfers heat in the die (2) through the spiral cooling channel (103) so as to cool the die;
s3): after the forming is finished, the die opening operation is carried out, an output shaft of a servo motor (51) drives a screw rod (52) to rotate, the screw rod (52) is in threaded transmission with a transmission nut (53), the transmission nut (53) drives a sliding block (42) to slide along a sliding groove (41), the sliding block (42) drives a die holder (12) to move through a connecting frame (13), so that a core die (11) is withdrawn from a die (2), then a linear motor (62) moves back and forth on a guide rail (61), the linear motor (62) drives a mounting seat (14) to move, and the die holder (12) moves in the front-back direction, so that the opening position of the die (2) is completely exposed;
s3): after the die opening is completed, the die stripping operation is carried out, an oil pump (94) conveys the die stripping agent in the storage box (91) to an atomization nozzle (92) through an atomization pipe (95), the atomization nozzle (92) sprays the die stripping agent into the pressure chamber (18), then an air compressor (71) pressurizes the pressure chamber (18) through a pressurizing pipe (72), the die stripping agent enters the die (2) through an air vent (17) under the pressure effect, and a formed aluminum profile product exits from the die (2) under the pressure effect, so that the die stripping operation is completed;
s4): when the release agent is required to be added into the storage tank (91), the switch valve (82) is opened, the release agent is required to be added into the storage tank (91) through the addition pipe (81), and the one-way valve (93) is used for avoiding the release agent in the pressure chamber (18) from flowing back.
