[0027] Example 1

[0028] Please see Figure 1-8 A cooling device for heat treatment of tire molds includes a base 1 and a fixed seat 2 fixedly installed on the top of the base 1 near the left side. A robot arm body 3 is installed in the middle of the top of the fixed seat 2, and a cooling box 4 is fixedly installed on the top of the base 1 near the right side. A drain pipe is fixedly installed through the right side of the cooling box 4 near the bottom, and a valve is provided on the outside of the drain pipe. A mesh frame 5 is provided above the inner cavity of the cooling box 4, and a movable plate 6 is provided above the top of the mesh frame 5. Lifting components 7 are installed in the middle of the front and rear sides of the movable plate 6, and stirring components 8 are installed in the front and rear sides of the cooling box 4 near the top. The lifting components 7 can drive the mesh frame 5 to move back and forth up and down, and the stirring components 8 can stir the coolant in the cooling box 4.

[0029] The lifting assembly 7 includes connecting rods 71 ​​fixedly installed at the middle of the front and rear sides of the movable plate 6, and threaded sleeves 72 fixedly installed at the outer ends of the connecting rods 71. Threaded rods 73 are threaded through the middle of the upper part of the threaded sleeves 72, and the lower ends of the threaded rods 73 are movably installed on the base 1. The output ends of the threaded rods 73 are fixedly sleeved with synchronous pulleys A, and synchronous belts A74 are sleeved on the outer sides of the synchronous pulleys A. A servo motor 75 is provided at the upper end of the front threaded rod 73, and the output end of the servo motor 75 is fixedly connected to the upper end of the front threaded rod 73. A fixing frame 76 is fixedly installed on the top of the servo motor 75, and the lower end of the fixing frame 76 is fixedly installed on the base 1, which can drive the mesh frame 5 to move up and down, which is beneficial for cooling and picking up the mold.

[0030] The threaded rod 73 involved in the patent meets the requirement of synchronous rotation under the transmission of the synchronous belt A74. Moreover, the synchronous belt A74 and the threaded rod 73 are mature existing technologies and there are no problems such as separation or inability to rotate synchronously.

[0031] Sliding plates 721 are fixedly installed on the outer side of the threaded sleeve 72, and T-shaped sliding rods 722 are slidably installed on the sliding plates 721. The lower ends of the T-shaped sliding rods 722 are fixedly installed on the base 1, which serves to guide and limit the movement of the threaded sleeve 72.

[0032] Fixed rods 61 are fixedly installed at the bottom of the movable plate 6 near the four corners, and the lower ends of the fixed rods 61 are fixedly installed on the mesh frame 5, which can drive the mesh frame 5 to move up and down synchronously with the movable plate 6 through the fixed rods 61.

[0033] In this embodiment: During use, the heat-treated mold can be removed by the robotic arm body 3 and placed in the inner cavity of the mesh frame 5. After placement, the servo motor 75 can be started. When the servo motor 75 is running, it will drive the front threaded rod 73 to rotate. Under the transmission of the synchronous belt A74, the front and rear threaded rods 73 will rotate synchronously. When the threaded rod 73 rotates, it will drive the adjacent threaded sleeve 72 to move downward synchronously. When the threaded sleeve 72 moves downward, it will drive the movable plate 6 to move downward through the adjacent connecting rod 71. When the movable plate 6 moves downward, it will drive the mesh frame 5 to move downward through the fixed rod 61. This allows the mold in the mesh frame 5 to be immersed in the coolant in the cooling box 4, which cools the mold. Conversely, it will drive the mesh frame 5 to move upward to restore its original position, making it easier for the operator to pick up.

Figure 1 and Figure 3-7 The stirring assembly 8 includes reciprocating screws 81 respectively located on the front and rear sides of the cooling tank 4 near the top, and rotating rods respectively fixedly installed through the middle of the reciprocating screws 81. Side plates 82 are respectively provided at the left and right ends of the reciprocating screws 81. The inner sides of the side plates 82 are fixedly installed on the cooling tank 4. The left end of the rotating rod is movably installed on the adjacent side plate 82, and the right end of the rotating rod extends movably through to the outer side of the adjacent side plate 82. The output end of the rotating rod is fixedly sleeved with a synchronous pulley B. The outer side of the synchronous pulley B is jointly sleeved with a synchronous belt B83. A drive motor 84 is provided on the right side of the right rear side plate 82. The output end of the drive motor 84 is fixedly connected to the right end of the rear rotating rod. A support plate is fixedly installed at the bottom of the drive motor 84. The left side of the support plate is fixedly installed on the right rear side plate 82. This assembly can stir the coolant in the cooling tank 4, which can make the coolant flow and thus improve the cooling effect.

[0036] A screw nut 85 is movably installed on the outer side of the reciprocating screw 81 near the right end. An L-shaped plate 86 is fixedly installed at the middle of the top of the screw nut 85. An agitator shaft 87 is movably installed on the bottom of the inner side of the L-shaped plate 86. A transmission gear 88 is fixedly sleeved on the outer side of the agitator shaft 87 near the upper end. Several agitator rods 89 are fixedly sleeved on the outer side of the agitator shaft 87 at equal intervals. The coolant in the cooling tank 4 can be agitated by rotating the agitator rods 89.

[0037] The transmission gear 88 has a transmission rack plate 881 meshing on opposite sides, and the bottom of the transmission rack plate 881 is fixedly installed on the cooling box 4, which facilitates the rotation of the transmission gear 88.

[0038] Guide plates 851 are fixedly installed at the bottom of the lead screw nut 85, and guide rods 852 are slidably installed through the guide plates 851. The left and right ends of the guide rods 852 are fixedly installed on the adjacent side plates 82, which serve to guide and limit the movement of the lead screw nut 85.

[0039] In this embodiment: When the mold is cooling, the drive motor 84 can be run. When the drive motor 84 runs, it will drive the rear rotating rod to rotate. Under the transmission of the synchronous belt B83, the front and rear rotating rods will rotate synchronously. When the rotating rods rotate, they will drive the adjacent reciprocating lead screw 81 to rotate. When the reciprocating lead screw 81 rotates, it will drive the adjacent lead screw nut 85 to move left and right synchronously. When the lead screw nut 85 moves left and right, it will drive the stirring shaft 87 to move left and right through the L-shaped plate 86. When the stirring shaft 87 moves left and right, it will drive the transmission gear 88 to move. When the transmission gear 88 moves, it will mesh with the transmission rack plate 881, which will cause the transmission gear 88 to rotate. When the transmission gear 88 rotates, it will drive the stirring shaft 87 to rotate. When the stirring shaft 87 rotates, it will drive several stirring rods 89 to rotate, thereby agitating the coolant and making the coolant flow, improving the full contact between the coolant and the mold and the cooling effect.

[0040] Working Principle: During use, the heat-treated mold can be removed by the robotic arm body 3 and placed into the inner cavity of the mesh frame 5. After placement, the servo motor 75 is activated. The servo motor 75 drives the front threaded rod 73 to rotate, and under the transmission of the synchronous belt A74, the front and rear threaded rods 73 rotate synchronously. When the threaded rod 73 rotates, it drives the adjacent threaded sleeve 72 to move downward synchronously. When the threaded sleeve 72 moves downward, it drives the movable plate 6 downward through the adjacent connecting rod 71. When the movable plate 6 moves downward, it drives the mesh frame 5 downward through the fixed rod 61. This allows the mold in the mesh frame 5 to be immersed in the coolant in the cooling box 4, thus cooling the mold. Conversely, it drives the mesh frame 5 to move upward to return to its original position, making it easier for the operator to pick up. During mold cooling, the drive can... When the drive motor 84 runs, it drives the rear rotating rod to rotate. Under the transmission of the synchronous belt B83, the front and rear rotating rods rotate synchronously. When the rotating rods rotate, they drive the adjacent reciprocating lead screw 81 to rotate. When the reciprocating lead screw 81 rotates, it drives the adjacent lead screw nut 85 to move left and right synchronously. When the lead screw nut 85 moves left and right, it drives the stirring shaft 87 to move left and right through the L-shaped plate 86. When the stirring shaft 87 moves left and right, it drives the transmission gear 88 to move. When the transmission gear 88 moves, it meshes with the transmission rack plate 881, which makes the transmission gear 88 rotate. When the transmission gear 88 rotates, it drives the stirring shaft 87 to rotate. When the stirring shaft 87 rotates, it drives several stirring rods 89 to rotate, thereby agitating the coolant, making the coolant flow, improving the full contact between the coolant and the mold, and enhancing the cooling effect.
