10. A control method of automatic production equipment for double or multiple colors of sole disc injection molding machine comprises the following steps:

step 1, stopping rotating the disc after the second sensor detects that the die reaches a set position; the middle mold clamping brackets (31) on two sides of the automatic mold opening device (3) are driven by the middle mold clamping cylinders (311) to move forwards, the upper U-shaped arms of the middle mold clamping brackets (31) are clamped on the compression mold rods (121) on two sides of the middle mold (13), and the lower U-shaped arms of the middle mold clamping brackets (31) are clamped on the U-shaped arm limiting frames (34) so that the middle mold (13) cannot move;

step 2, an upper die hook (411) of the first mechanical arm vertically moves under the action of a fourth driving device (417), a middle die hook (412) of the first mechanical arm vertically moves under the action of the fourth driving device, and the middle die hook (412) continuously vertically moves below the upper die hook (411) under the action of a third driving device (415); then the first mechanical arm moves forwards under the action of the first driving device, so that an upper die hook (411) of the first mechanical arm is positioned below a die opening rod (141) connected with the side surface of the upper die (14), and a middle die hook (412) is also positioned below a die pressing rod (131) of the middle die (13);

step 3, starting a top buckling cylinder (321), wherein a top buckling plate (33) moves upwards in the vertical direction under the action of the top buckling cylinder (321) and can jack a die locking buckle (142) between an upper die (14) and a lower die (11);

step 4, after the mold locking buckle (142) is pushed open, starting the top mold cylinder (331), and enabling the top mold plate (32) to move upwards under the action of the top mold cylinder (331) and to jack up the top mold rod (143) of the upper mold (14) to push up the upper mold (14);

step 5, after the top-opening upper die (13) is opened to a set position, an upper die hook of the first mechanical arm moves upwards and forwards to hook an opening rod (141) connected with the side surface of the upper die (14) and thoroughly open the upper die (14);

step 6, restarting the middle mold clamping cylinder (311) to enable the middle mold clamping bracket (31) to return to the original position, wherein the middle mold clamping bracket (31) does not press the compression mold rod (131) of the middle mold (13);

step 7, the middle die hook of the first mechanical arm moves upwards and forwards, the middle die hook of the first mechanical arm hooks the die rod (131) of the middle die (13), the middle die (13) is opened, and a product in the lower die (11) is exposed;

step 8, a protection block (413) on the first mechanical arm moves downwards to prevent the middle die (13) and the upper die (14) from being closed;

step 9, starting the top buckle air cylinder (321) and the top die air cylinder (331) again to enable the top buckle plate (33) and the top die plate (32) to return to the original positions;

step 10, a second mechanical arm moves forwards to the upper part of a lower die (11) under the drive of a second driving device, a product clamp on the second mechanical arm moves downwards under the action of a seventh driving device (423) and clamps a product in the lower die (13) when the eighth driving device moves left and right to a set position;

step 11, a product clamp of the second mechanical arm moves upwards under the action of a seventh driving device (423), the second mechanical arm moves backwards to a product storage place under the driving of the second driving device, the product clamp releases a product, and the second mechanical arm (42) returns to the original position;

step 12, separating the first mechanical arm from the upper die (14) and the middle die (13) and returning to the original position; the upper die (14) and the middle die (13) are kept in an open state;

step 13, continuously rotating the disc, and after the first sensor detects that the die (1) reaches a set position, moving the swing arm (26) and the sliding seat (22) forwards under the driving of the air cylinder (21);

step 14, sleeving a sleeve (27) on the swinging arm (26) on a connecting rod (121) of the side cover plate (12), and stopping the cylinder (21);

step 15, under the combined action of a servo motor (24) and a speed reducer (25), the sleeve (27) rotates and swings to a set die closing position, and the side cover plate (12) closes the lower die (11); when the swinging arm (26) is closed, the swinging arm (26) and the sliding seat (22) are driven by the air cylinder (21) to move backwards and retract to the original position;

and step 16, restarting rotating the disc, moving the other die to a preset position determined by the second sensor, and repeating the steps 1-15.
