9. A control method applied to the mold-releasing mechanism according to claim 8, characterized by comprising the steps of: s1: the height of the demoulding mechanism is adjusted according to the size of the mould, and a threaded rod (43) is moved along the axial direction by rotating an adjusting nut (44) and is adjusted to a proper position;
s2; the pressure on two sides of a magnetic coupling piston (323) in a cylinder barrel (321) is respectively P1 and P2, the side P1 close to the die is P2;
s3; after the trimming process of the semi-finished product of the straw is finished, a controller (36) is used for controlling a three-position five-way valve (35) to increase the pressure of P2, so that a magnetic coupling piston (323) moves towards the direction of a mould, a clamping mechanism (2) is arranged above the mould, and a cylinder clamping jaw (23) is controlled to clamp the waste;
s4: the controller (36) is used again to control the three-position five-way valve (35) to increase the pressure of P1, so that the magnetic coupling piston (323) moves away from the die, after the magnetic coupling slide block (324) stops moving, the cylinder clamping jaw (23) is controlled to be opened, and the waste falls into the waste frame freely;
s5; and (5) continuously taking the waste material off the die by circulating the steps to complete the demoulding of the waste material.
