The worker pulls the rotating block 213 to rotate counterclockwise to ninety degrees again, the fixed shaft 212 is synchronously driven to move in the chute 2201 towards the direction away from the rotating block 213 in the process, the second tangent plane column 211 is synchronously driven to slide on the tangent plane under the first tangent plane column 210, the first tangent plane column 210 slides upwards in the notch sliding ring 2101, the vertical height of the first tangent plane column 210 is gradually increased, the arc-shaped column 26 fixedly connected with the top surface of the first tangent plane column 210 is also synchronously increased, the vertical height of the fixed seat 24 is also increased, the vertical height of the first rotating shaft 28 which is rotationally connected with the fixed seat 24 is also increased, the arc-shaped column 26 also moves upwards along with the second tangent plane column 211 sliding on the tangent plane under the first tangent plane column 210, and the buffer spring 25 is fixedly connected between the fixed seat 24 and the arc-shaped column 26, so that when the arc-shaped column 26 moves upwards, the buffer spring 25 is compressed under the pressure action of the arc-shaped column 26, the rising height of the arc-shaped column 26 is larger than the rising height of the fixed seat 24, the first connecting rod 27 is also increased to the first connecting rod 26029 is clamped in the first connecting rod 2601, and the first connecting rod 26029 is also horizontally clamped between the two connecting rods 26029 and is rotated in the first connecting rod 26029, and the first connecting rod is firmly connected with the first connecting rod 26029 and the first connecting rod is rotated in the horizontal position;

The lower die 23 is fixed on the moving plate 22 through the structure in the moving plate 22, the rotating bottom plate 2303 and the upper die 2304 can be fixed in the same way, so that die installation is realized, the upper die 23 and the lower die 23 can be conveniently and rapidly disassembled and replaced, and the conversion speed and the overall production efficiency of a production line are improved;

the positioning and forming machine for processing the rubber ring controls the first cylinder 13, the high-temperature vulcanizing machine 15, the second cylinder 16, the sliding plate 12 and the moving plate 22 through the electric connection of an external controller;

the prepared blank is uniformly placed on the lower die 23 by a worker, the limiting plate 2305 slides downwards along the sliding rod 11 under the control of the external controller until the limiting plate 2305 slides to be in contact with the sliding plate 12, and the upper die 2304 synchronously rotates on the transverse shaft 2302 with the rotating bottom plate 2303 and then moves downwards through the limiting plate 2305 as the limiting plate 2305 slides to be in contact with the sliding plate 12, and a positioning column 36 fixedly connected with the center of the upper die 2304 coincides with a positioning hole 35 formed in the center of the surface of the lower die 23, so that the die assembly is successful;

After the upper die 2304 and the lower die 23 are successfully clamped by an external controller, driving the upper die 2304 and the lower die 2303 by the driving controlled by the external controller again, so that the driving drives the movable plate 22 to slide above the second air cylinder 16 along the sliding rail 21, when the movable plate 22 slides to one end of the sliding rail 21 close to the second air cylinder 16, the movable plate 22 is positioned right above the second air cylinder 16, at the moment, the movable plate 22 stops sliding, at the moment, the external controller controls the second air cylinder 16 to lift, the second air cylinder 16 moves the movable plate 22, the lower die 23, the upper die 2304 and the rotating bottom plate 2303 upwards, when the rotating bottom plate 2303 is overlapped with the pressurizing machine 14, the pressurizing machine 14 carries out high-pressure shaping on the lower die 23 and the upper die 2304, a worker starts the procedure by the external controller to enable the first air cylinder 13 to move downwards, and enable the high-temperature vulcanizing machine 15 to be overlapped with the rotating bottom plate 2303, at the moment, the high-temperature vulcanizing machine 15 starts working the high-temperature vulcanizing the embryo between the lower die 23 and the upper die 2304 by the external controller, and the air vent hole 3103 is formed between the lower die 23 and the upper die 4 by the vertical air vent hole 35 and the first air vent hole 31;

The two sides of the first air vent 31 and the second air vent 3101 are symmetrically and fixedly connected with a second rotating shaft 32, the second rotating shaft 32 is rotationally connected with a Z-shaped rotating block 33, one side of the Z-shaped rotating block 33 far away from a positioning hole 35 is fixedly connected with a return spring 34, one end of the return spring 34 far away from the Z-shaped rotating block 33 is fixedly connected to the bottom surface of the first air vent 31 or the second air vent 3101, and when the return spring 34 is not stressed in a free state, the Z-shaped rotating block 33 fills the longitudinal section of the first air vent 31 or the second air vent 3101, so that external air cannot enter the die through the first air vent 31 and the second air vent 3101 in the die clamping process;

Because the positioning hole 35 and the positioning column 36 are positioned at the center of communication in the process of closing the lower die 23 and the upper die 2304, when gas is generated between the lower die 23 and the upper die 2304 in the process of closing the dies, the gas flows into the first air hole 31 and the second air hole 3101 through the positioning hole 35, the pressure generated by the gas makes the two sides of the Z-shaped rotating block 33 close to the positioning hole 35 and far away from the positioning hole 35 generate air pressure difference, the Z-shaped rotating block 33 rotates outwards in the first air hole 31 and the second air hole 3101 through the second rotating shaft 32 under the action of the air pressure, the reset spring 34 is stressed and compressed, the Z-shaped rotating block 33 rotates to enable the first air hole 31 and the second air hole 3101 to be communicated with the outside, redundant gas is discharged outside the device, after the gas between the lower die 23 and the upper die 2304 is discharged, the pressure born by the two sides of the Z-shaped rotating block 33 is the same, the reset spring 34 is restored to the original state, and then the Z-shaped rotating block 33 is driven to rotate on the second rotating shaft 32, so that the Z-shaped rotating block 33 is filled with the first air hole 31 or the second air hole 3101;

When no gas is generated during the die assembly between the lower die 23 and the upper die 2304, that is, when the stress of the Z-shaped rotating block 33 is balanced, the first air vent 31 and the second air vent 3101 are blocked by the actions of the Z-shaped rotating block 33 and the return spring 34, and because the fluororubber material easily generates bubbles and air holes during the processing process, the quality and the performance of a product are affected, the gas in the die cavity can be effectively removed by increasing the gas exhaust channel, the generation of the bubbles and the air holes is reduced, and the quality of a formed product is improved.

Finally, after the rubber ring of the fluororubber is processed, the worker operates the external controller to reset the first cylinder 13 downwards, then moves the second cylinder 16 downwards to enable the movable plate 22, the lower die 23, the upper die 2304 and the rotating bottom plate 2303 to move downwards until the movable plate 22 is placed on the sliding rail 21, then slides the movable plate 22 on the sliding rail 21 to the original position through a program of the controller, one end of the sliding rail 21 far away from the sliding rod 11 is fixedly connected to the fixed column 17, the inner sides of the two square columns 2301 are rotationally connected with the transverse shaft 2302, the program of the external controller enables the limiting plate 2305 to lift upwards, the rotating bottom plate 2303 above the limiting plate 2305 is synchronously driven, after the rotating bottom plate 2303 is lifted to the height of the transverse shaft 2302, the limiting plate 2305 continues to slide upwards along the sliding rod 11 for a certain distance, at this time, the rotating bottom plate 2303 is rotated with the transverse shaft 2302 as a center, at this time, the lower die 23 is separated from the upper die 2304, the worker can take off the processed semi-finished rubber ring, and then place a new embryo, and the worker can reciprocate to process.
