The working procedures and principles related to the whole contents of the first to second embodiments are as follows:

when air flows, the movement conditions of molecules are different, so that the pressure of gas also changes, and when the gas flows, all air molecules have a larger impact effect in the flowing direction, the pressure is increased, and the pressure formed by the flowing of the gas flow is called dynamic pressure;

when a worker needs to injection mold soles, raw materials are injected into a mold groove formed in the lower mold 1, after injection is completed, an upward force is applied to the handle 22, so that the handle 22 rotates upwards by taking the mounting seat 21 as a circle center, a certain pressure is applied to a torsion spring 23 connected between the handle 22 and the mounting seat 21, when the handle 22 rotates to 90 degrees, the upper end of the rope 20 is synchronously pulled to move, at the moment, the rope 20 synchronously pulls a sliding block 25 connected with the lower end to slide upwards in a sliding groove 24, a clamping plate 26 fixedly connected with the sliding block 25 is driven to slide out from a clamping groove 28 formed in the fixing plate 27, and when the clamping plate 26 slides out completely from the clamping groove 28, the worker can apply a thrust in the direction of the lower mold 1 to the upper mold 2, so that the upper mold 2 rotates by taking the rotating shaft 4 as the circle center and is completely attached to the upper end face of the lower mold 1;

in the process that the upper die 2 rotates by taking the rotating shaft 4 as the center of a circle, the second connecting rod 14 fixedly connected with the outer surface of the rotating shaft 4 is synchronously driven to rotate, at the moment, one end of the second connecting rod 14 far away from the rotating shaft 4 rotates around the rotating shaft 4 and pulls the lower end of the first connecting rod 13 to move, in the process that the lower end of the first connecting rod 13 moves along with the upper end of the second connecting rod 14, the piston rod 12 is synchronously pulled to slide out of the air suction cylinder 9, at the moment, air remained in the air suction groove 15 can be sucked into the air suction cylinder 9 through the air suction pipe 10, negative pressure is formed in the air suction groove 15 along with the reduction of the air in the air suction groove 15, so that the movable frame 6 slides into the air suction groove 15, and the fixed shaft 16 connected between the movable frames 6 can drive the shovel blade 7 to slide from the rear side to the front side on the upper end surface of the lower die 1, so that the shovel blade 7 slides out from the upper end surface of the lower die 1;

when the fixed shaft 16 drives the shovel 7 to slide and approach the protection plate 18, the linkage plate 17 connected to the outer surface of the fixed shaft 16 can contact the roller 19 on the protection plate 18 in advance, so that the roller 19 slides upwards from below on the inclined surface of the linkage plate 17, the roller 19 is lifted, at the moment, the protection plate 18 can slide upwards on the protection shell 8, when the protection plate 18 rises to the highest position, the shovel 7 just slides to pass through the protection plate 18, when the fixed shaft 16 drives the shovel 7 to continuously approach the protection shell 8, the roller 19 can slide downwards along the inclined surface of the other side, at the moment, the protection plate 18 is influenced by gravity and automatically moves downwards on the protection shell 8, the shovel 7 is limited between the protection shell 8 and the protection plate 18, the shovel 7 is protected, the problem that the shovel 7 is exposed outwards and is influenced by external factors and the knife edge is worn is avoided, and the situation that operators are accidentally hurt by the shovel 7 in the process of other operations by manpower is prevented;

after the raw materials between the upper die 2 and the lower die 1 are processed into soles, a worker lifts the handle 22 upwards to drive the upper die 2 to rotate upwards by taking the rotating shaft 4 as the center of a circle and separate from the lower die 1, in the process of rotating the upper die 2, the second connecting rods 14 connected with the two sides of the outer surface of the rotating shaft 4 are synchronously driven to rotate by taking the rotating shaft 4 as the axis to change from a horizontal lying state to a vertical state, at the moment, the lower ends of the first connecting rods 13 are synchronously pushed by the second connecting rods 14 to move upwards, the piston rods 12 connected with the upper ends of the first connecting rods 13 are pushed into the air extraction cylinders 9, in the process of sliding the piston rods 12 into the air extraction cylinders 9, air in the air extraction cylinders 9 can be injected into the air extraction grooves 15, the air extraction grooves 15 push the movable frame 6 to slide out of the air extraction grooves 15 along with the injection of the air, and drive the shovels 7 to slide from the front and back through the fixed shafts 16, in the process of sliding the shovels 7 from the front and back, the outer surfaces of the fixed shafts 16 are contacted with the rollers 19 at first, the upper end faces of the protection plates 18 are pushed to slide upwards, then the upper end faces of the protection plates 8 are pushed by the protection plates 8 and then slide from the upper end faces of the protection plates 8 and the lower die 1 and the lower end faces of the protection plates 1 are simultaneously, and the bottoms of the soles can not slide out of the soles 1 and the protection plates are simultaneously slid from the front end faces of the upper die 1 and the upper end faces and the lower die 1;

when the worker manipulates the upper die 2 to rotate and approach to the vertical direction, the handle 22 is loosened, the handle 22 is automatically driven to be attached to the surface of the upper die 2 by the rebound force of the torsion spring 23, the upper end of the rope 20 connected to the handle 22 loses tension in the process of rotationally attaching the handle 22 to the surface of the upper die 2, at this time, the slide block 25 slides downwards from the upper part of the slide groove 24 due to the approach to the vertical direction as well as the upper die 2, and meanwhile, the clamping plate 26 is driven to move downwards, so that the lower end of the clamping plate 26 is clamped into the clamping groove 28 formed at the upper end of the fixing plate 27, the upper die 2 can be limited, the situation that the upper die 2 is automatically moved due to the external influence is avoided, and after the upper die 2 is fixed, the worker can take out the soles formed in the lower die 1.
