6. The clamping method based on the die casting machine die plate rapid clamping device is characterized by comprising the following steps of: the method comprises the following steps:
step one, when the movable die (2) is installed, the whole rubber clamping wheel (16) is required to be butted through a groove in the fixed die plate (1), pressure is generated in the butting process, the rubber clamping wheel is contracted towards the inside of the auxiliary guide groove (13), after the movable column (33) is propped against the positioning block (34), the upper end face of the rubber clamping wheel (16) is kept at the same horizontal plane with the groove in the fixed die plate (1), and is simultaneously contacted with the movable die (2), at the moment, the driving device (17) is started, the rubber clamping wheel (16) is driven to rotate through the transmission shaft (36), and at the moment, the rubber clamping wheel (16) and the movable die (2) enable the movable die (2) to move towards the inside of the fixed die plate (1) under the action of friction force;
step two, adjusting a locking connecting rod (8) provided with a limiting rod (9) according to the position of a limiting groove (37) of a movable die (2), and enabling a locking mechanism (6) on an adjusting block (5) to realize independent adjustment in the vertical direction under the friction fit of a threaded transmission rod (4) and the adjusting block (5) by starting a first servo motor (18) when the limiting groove (37) on the movable die (2) is asymmetric so as to adapt to different types of movable dies (2);
step three, if the upper limit grooves (37) of the movable die (2) are symmetrically distributed, opening the electric push rod (22) in the lower end linkage cavity (10), driving the spline rod (23) at one end to move towards the second connecting column (12) until the spline rod extends into the spline groove (25), forming limit positions of the first connecting column (11) and the second connecting column (12), then independently opening the lower end first servo motor (18), and symmetrically sliding the moving direction of the regulating block (5) by the horizontal center line of the fixed die plate (1);
step four, after the regulating block (5) drives the locking mechanism (6) to move to a proper position, the hydraulic driving device (7) is started, the locking connecting rod (8) drives the limiting rod (9) to move towards the direction of the limiting groove (37), the inclined surface of the wedge block (26) is contacted with the inclined surface of the limiting groove (37), the wedge block (26) and the limiting groove (37) are pressed more tightly along with the continuous inward movement of the limiting rod (9), meanwhile, the guide channel (28) on the limiting rod (9) keeps upward in the moving process, the guide channel (28) can extend along the auxiliary fixing block (30), after reaching the clamping position, the second servo motor (32) inside the locking connecting rod (8) is started, and the output shaft drives the limiting rod (9) to rotate, so that the auxiliary fixing groove (27) is clamped in the auxiliary fixing block (30) to realize reinforcement.
