Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aircraft tires, and in particular to a demolding device for a rubber vulcanizing machine. Background Technology
[0002] Vulcanization and shaping refers to placing the wound tire blank into a vulcanizing machine and using methods such as heating, pressurizing, and inflation to make the tire blank fit tightly with the mold, thereby forming the shape and structure of the tire.
[0003] Existing vulcanizing machine demolding devices, such as the flat vulcanizing machine demolding device disclosed in utility model patent application number 202322749309.8, mainly include a support plate. Support legs are fixedly connected to the four corners of the lower end face of the support plate. A demolding mechanism is provided below the support plate, and a molding mechanism and a pushing mechanism are provided on the upper end face of the support plate. The pushing mechanism includes two support blocks, which are respectively fixedly connected to both sides of the upper end face of the support plate. In use, a synchronous motor is started, which drives the threaded rod that is connected to it to rotate. The rotation of the threaded rod drives the pushing plate to move back and forth along the slide. The movement of the pushing plate pushes the workpiece located on the molding mechanism to the inclined plate. The workpiece pushed to the inclined plate slides out of the molding mechanism along the inclined surface of the inclined plate.
[0004] However, most existing demolding devices require the clamps to be inserted into the mold to hold the tire, which can easily damage the mold and the tire. Moreover, the temperature of the tire after demolding is usually above 150°C, which can easily burn the surrounding workers and requires a long time to cool naturally, which is very troublesome. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a rubber vulcanizing machine demolding device that can not only fix the tire with a heat-resistant silicone suction cup to prevent the device from scratching the mold and the tire and extend the service life of the device, but also accelerate the cooling of the tire, so as to make the upper and lower sides of the tire dissipate heat evenly and improve the working efficiency.
[0006] This utility model discloses a demolding device for a rubber vulcanizing machine, including a vulcanizing mechanism; it also includes a driving mechanism, a clamping mechanism, a spraying mechanism, a supporting mechanism, and a blowing mechanism. The driving mechanism is installed on the vulcanizing mechanism and drives the clamping mechanism to move. The clamping mechanism is installed on the driving mechanism and clamps the tire. The spraying mechanism is installed on the vulcanizing mechanism and sprays the tire to cool it down. The supporting mechanism is installed on the spraying mechanism and supports the tire. The blowing mechanism is installed on the vulcanizing mechanism and blows away any residual water stains on the tire. The vulcanizing mechanism vulcanizes and shapes the tire. After shaping, the driving mechanism drives the clamping mechanism to move above the tire, and the clamping mechanism clamps the tire. The driving mechanism moves the clamping mechanism and the tire to the supporting mechanism. At the same time, the other end of the clamping mechanism pushes the tire already on the supporting mechanism forward. The supporting mechanism cools the bottom of the tire. The spraying mechanism atomizes the cooling water and sprays it out to fix the tire. The blowing mechanism blows away the water stains on the tire in front of it.
[0007] Preferably, the vulcanizing mechanism includes a protective box, four sets of guide columns, a lower mold, two sets of hydraulic cylinders, an upper mold, and four sets of positioning rings. The bottom of the protective box is connected to the ground. All four sets of guide columns are mounted on the protective box. The lower mold is mounted on the protective box. All two sets of hydraulic cylinders are mounted on the protective box, and each set of hydraulic cylinders has a synchronization valve on its oil circuit. The top of the upper mold is connected to the bottom of the two sets of hydraulic cylinders. All four sets of positioning rings are mounted on the upper mold and are slidably mounted on the four sets of guide columns. The operator places the tire blank on the lower mold, and the two sets of hydraulic cylinders synchronously push the upper mold down. The four sets of positioning rings and four sets of guide columns work together to limit the upper mold, ensuring that the upper mold and the lower mold close together to vulcanize and shape the tire blank. After shaping, the two sets of hydraulic cylinders synchronously drive the upper mold to lift.
[0008] Preferably, the drive mechanism includes two sets of lead screw boxes, a dual-head motor, two sets of reducers, two sets of right-angle steering gears, and two sets of reciprocating lead screws. Both sets of lead screw boxes are mounted on a protective housing. The dual-head motor is mounted on the protective housing.

The output end of the two sets of reducers is connected to the input end of the two sets of right-angle steering gears, and the input end of the two sets of right-angle steering gears is connected to the input end of the two sets of reciprocating lead screws. When the dual-head motor is started, it drives the two sets of reciprocating lead screws to rotate through the two sets of reducers and the two sets of right-angle steering gears. The two sets of reciprocating lead screws drive the clamping mechanism to slide back and forth on the two sets of lead screw boxes.
[0009] Preferably, the clamping mechanism includes a slider, three sets of cylinders, and three sets of heat-resistant silicone suction cups. The slider is slidably mounted on two sets of lead screw boxes and connected to two sets of reciprocating lead screws via threaded transmission. All three sets of cylinders are mounted on the slider, and the tops of the three sets of heat-resistant silicone suction cups are respectively connected to the bottoms of the three sets of cylinders. When the slider moves above the tire, the three sets of cylinders push the three sets of heat-resistant silicone suction cups down to adsorb the tire. Then, the three sets of cylinders retract to lift the tire and remove it from the lower mold. Then, the two sets of reciprocating lead screws drive the slider and the tire to move above the support mechanism, place the tire on the support mechanism, and simultaneously push the previous tire forward.
[0010] Preferably, the spraying mechanism includes a first water supply pipe, a first valve, a spray plate, and multiple sets of atomizing nozzles. The first water supply pipe is installed on the protective box and connected to the water supply pump. The first valve is installed on the first water supply pipe. The spray plate is installed on the protective box and connected to the inside of the first water supply pipe. Multiple sets of atomizing nozzles are all installed on the spray plate. When the operator opens the first valve, the water supply pump delivers cooling water to the spray plate through the first valve. The cooling water is then atomized and sprayed out through the multiple sets of atomizing nozzles to facilitate cooling of the top of the tire.
[0011] Preferably, the support mechanism includes a second water supply pipe, a second valve, a water distributor, multiple sets of water-cooled rollers, and a drainage bucket. The second water supply pipe is internally connected to the first water supply pipe. The second valve is installed on the second water supply pipe.

The multiple sets of water-cooled rollers are rotatably installed on the protective box and are internally connected to the water distributor. The drainage bucket is installed on the protective box. The tire is placed on the multiple sets of water-cooled rollers. When the second valve is opened, the cooling water in the first water supply pipe is transported to the water distributor through the second water supply pipe. The water distributor transports the cooling water to the multiple sets of water-cooled rollers. The multiple sets of water-cooled rollers cool the bottom of the tire. The cooling water sprayed by the spraying mechanism gathers in the drainage bucket and is discharged.
[0012] Preferably, the purging mechanism includes an air pump, a filter box, an air supply pipe, three sets of air distribution pipes, and multiple sets of nozzles.
