[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The spline shaft is designed as a pagoda structure. The first layer is a six-tooth spline, which is used to connect the mold connection plate and the anti-rotation ring on the radial tire mold. The second layer is a positioning hoisting plate step. The hoisting plate can rotate arbitrarily and move slightly axially along the spline shaft at this step. The third layer is a positioning step for the gasket and the bearing. The gasket and the bearing are designed to rotate arbitrarily along the spline shaft. The fourth layer is designed as an axial positioning step for the lock nut and the bearing. This step is also used for the axial positioning of the gasket, the bearing and the lock nut. The lifting ring on the top of the spline shaft is designed as a fixed lifting ear structure, which is used to rotate the spline shaft to change the angle for easy insertion into the mold connection plate, and can also be used to lift the body. It can avoid large shaking when lifting the radial tire mold, and it can be installed and operated conveniently to improve efficiency.

[0016] 2. When the radial tire mold rotates on the bearing, the bearing drives the second extrusion block to rotate. When the second extrusion block rotates inside the track, it is squeezed with the first extrusion block to displace the first extrusion block. The first extrusion block drives the moving ring to displace inside the mounting groove. The moving ring drives the first extrusion rod to move. The first extrusion rod drives the second extrusion rod to move inside the oil outlet pipe. The second extrusion rod drives the connecting piece to move to cancel the sealing connection between the connecting piece and the sealing disk. At this time, the lubricating oil inside the oil storage cylinder will flow out through the gap between the connecting piece and the sealing disk. The lubricating oil will slide along the second extrusion rod and drip on the surface of the bearing, which can automatically add lubricating oil to the bearing to avoid the bearing from rotating stiffly and causing accidents.

[0017] 3. When the second extrusion rod moves upward, the second extrusion rod drives the connecting piece to move, and the connecting piece drives the connecting tube to move along the threaded rod. At the same time, the connecting tube is rotated by the thread engraved on one end of the threaded rod. The rotation of the connecting tube can stir the lubricating oil to accelerate the flow of the lubricating oil and avoid the solidification of the lubricating oil. At the same time, it can avoid that the time for canceling the sealing connection between the connecting piece and the sealing disk is too short, resulting in too little lubricating oil flowing out.

[0033] like Figure 5 , Figure 6 As shown, a second extrusion block 105 is installed on the surface of the bearing 4, and a track 1011 is opened at the bottom of the lock nut 7. The track 1011 is connected with the installation groove 1012. The second extrusion block 105 slides inside the track 1011. By sliding the second extrusion block 105 inside the track 1011, the stability of the lock nut 7 when sliding can be maintained. At the same time, when the second extrusion block 105 passes through the installation groove 1012, it can contact the first extrusion block 104 and squeeze the first extrusion block 104 to cause displacement.

[0034] like Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a moving ring 103 is slidably connected to the surface of the oil outlet pipe 102, and the moving ring 103 slides inside the mounting groove 1012.

The telescopic spring 107 can make the moving ring 103 return to the starting position after displacement.

[0036] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a first extrusion rod 106 is fixedly installed on one side of the bottom of the movable ring 103, and the first extrusion rod 106 is L-shaped. A second extrusion rod 1010 is fixedly installed on one end of the first extrusion rod 106. The ends of the second extrusion rod 1010 and the first extrusion rod 106 that are interconnected are both conical. One end of the second extrusion rod 1010 slides inside the oil outlet pipe 102. A sealing disk 109 is installed inside the oil outlet pipe 102. The second extrusion rod 1010 and the sealing disk 109 are slidably connected. A stirring assembly 108 is arranged inside the oil outlet pipe 102. The ends of the second extrusion rod 1010 and the first extrusion rod 106 that are interconnected are both conical, so that the lubricating oil can slide along the second extrusion rod 1010, thereby preventing the lubricating oil from solidifying on the second extrusion rod 1010 and failing to flow onto the bearing 4.

[0037] like Figure 5 , Figure 6 As shown, the stirring assembly 108 includes a mounting block 1081, which is fixedly mounted inside the oil outlet pipe 102. A threaded rod 1082 is fixedly mounted on one end of the mounting block 1081. A threaded rod 1082 is engraved on one end surface of the threaded rod 1082. The connecting tube 1084 is driven to move through the connecting piece 1085. The connecting tube 1084 moves along the threaded rod 1082. Through the threaded design on the threaded rod 1082, the stirring paddle 1083 is driven to rotate at the same time when the connecting tube 1084 moves along the threaded rod 1082, thereby stirring the lubricating oil and preventing the lubricating oil from solidifying.

[0038] like Figure 5 , Figure 6 , Figure 7 As shown, a connecting piece 1085 is fixedly installed on the top of the second extrusion rod 1010, and the connecting piece 1085 is sealed and connected with the sealing disk 109 through it, and the diameter of the connecting piece 1085 is 1.5 to 2 times the diameter of the second extrusion rod 1010, and a connecting tube 1084 is rotatably arranged on the top of the connecting piece 1085, and the threaded rod 1082 is screwed to the connecting tube 1084, and the threaded rod 1082 rotates the connecting tube 1084 through the bottom thread, and a stirring paddle 1083 is fixedly installed on the surface of the connecting tube 1084, and the diameter of the connecting piece 1085 is 1.5 to 2 times the diameter of the second extrusion rod 1010, so that the second extrusion rod 1010 can drive the connecting piece 1085 to cancel the connection with the sealing disk 109, and the lubricating oil can flow out from the gap between the connecting piece 1085 and the sealing disk 109.

[0039] Working principle: When in use, first safely hoist the radial tire mold 9 and place it flat on the ground, so that the bottom of the spline shaft 1 touches the ground, and then the forklift fork enters the bottom of the hoisting plate 5 from any direction, the fork rises to lift the radial tire mold 9 and safely hoist it to a plane higher than the mold connecting plate 3. The forklift moves forward to basically align the axis center line of the spline shaft 1 with the axis center line of the mold connecting plate 3, and then the fork descends. At this time, the maintenance personnel assist in inserting the spline shaft 1 into the six-tooth gear sleeve inside the mold connecting plate 3 and then rotate the spline shaft 1 so that the two-tooth spline at the bottom of the anti-rotation ring 2 is inserted between the spline shaft 1 and the two teeth of the six-tooth spline sleeve inside the mold connecting plate 3 and locked, and the spline shaft 1 and the mold are locked. The radial tire mold 9 is fixed with the tool connecting plate 3, and finally the forklift fork rises to lift the radial tire mold 9 and safely hoist it to the vulcanizer. After matching the radial tire mold 9 with the central mechanism of the vulcanizer, the maintenance personnel can rotate it on the spline shaft 1 through the bearing 4. The maintenance personnel can easily rotate the radial tire mold 9 and adjust the position. In addition, when the radial tire mold 9 is rotated through the bearing 4, the bearing 4 drives the second extrusion block 105 to rotate. When the second extrusion block 105 rotates inside the track 1011, it squeezes with the first extrusion block 104, so that the first extrusion block 104 is displaced, and the first extrusion block 104 drives the moving ring 103 to move inside the mounting groove 1012. The first extrusion rod 106 moves, and the first extrusion rod 106 drives the second extrusion rod 1010 to move inside the oil outlet pipe 102. The second extrusion rod 1010 drives the connecting piece 1085 to move so that the sealing connection between the connecting piece 1085 and the sealing disk 109 is cancelled. At this time, the lubricating oil inside the oil storage cylinder 101 will flow out through the gap between the connecting piece 1085 and the sealing disk 109, and the lubricating oil will slide along the second extrusion rod 1010 and drip on the surface of the bearing 4, so that the lubricating oil can be automatically added to the bearing 4. When the second extrusion rod 1010 moves upward, the second extrusion rod 1010 drives the connecting piece 1085 to move. 85 moves, the connecting piece 1085 drives the connecting cylinder 1084 to move along the threaded rod 1082, and at the same time, the connecting cylinder 1084 is rotated by the thread engraved on one end of the threaded rod 1082. The rotation of the connecting cylinder 1084 can stir the lubricating oil, accelerate the flow of the lubricating oil, and avoid the lubricating oil solidification. At the same time, it is prevented that the time for the connecting piece 1085 and the sealing disk 109 to cancel the sealing connection is too short, and too little lubricating oil flows out. During the use of the device, the bearing will be affected by long-term work and frequent use, resulting in the consumption of the lubricating oil when the bearing is packaged, resulting in increased friction and rotation stiffness inside the bearing. It is preferred to use a tapered bearing.
