[0035] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0036] like Figure 1-3 As shown, the utility model provides a large rotary die oil cooling and lubrication integrated circulation system, comprising:

[0037] Die base 100;

[0038] A rotary support sleeve 110, which is installed in the mold base 100 and has a support cavity 111;

[0039] The die rotary sleeve 120 is installed in the supporting cavity 111;

[0040] The upper skeleton oil seal 130 and the lower skeleton oil seal 140 are respectively arranged on the upper and lower sides of the support cavity 111. The rotary support sleeve 110 and the die rotary sleeve 120 are sealed and connected by the upper skeleton oil seal 130 and the lower skeleton oil seal 140. At this time, a closed bearing cavity 150 is formed between the inner wall of the rotary support sleeve 110 and the outer wall of the die rotary sleeve 120.

[0041] A plurality of bearings are provided and installed in the bearing cavity 150;

[0042] The oil cooler 200 , the mold base 100 , and the rotary support sleeve 110 are provided with a connected oil inlet channel 160 and an oil outlet channel 170 . The oil inlet channel 160 is connected to the oil outlet channel 170 through the bearing cavity 150 , and the oil inlet channel 160 and the oil outlet channel 170 are respectively connected to the oil cooler 200 .

[0043] That is to say, in this embodiment, the gap between the rotary support sleeve 110 and the die rotary sleeve 120 is sealed by the upper skeleton oil seal 130 and the lower skeleton oil seal 140 to ensure the sealing of the bearing cavity 150. The cooling oil provided by the oil cooler 200 first enters the bearing cavity 150 along the oil inlet channel 160, and then flows back to the oil cooler 200 through the oil outlet channel 170 for cooling, thereby circulating reciprocatingly, wherein,

[0044] When the cooling oil flows through the bearing cavity 150, it can not only cool down the die rotary sleeve 120, but also lubricate the bearings in the bearing cavity 150, thereby reducing the wear of the bearings and ensuring the accuracy and production efficiency of the mold.

[0045] Preferably, a pulley 180 is further included, and the bottom end of the die rotary sleeve 120 passes through the rotary support sleeve 110 and is connected to the pulley 180. An external power (such as a motor) drives the pulley 180 to rotate through a transmission belt, thereby driving the die rotary sleeve 120 to rotate.

[0046] Preferably, the die rotating sleeve 120 is arranged in a stepped manner, and includes a first rotating part 121, a second rotating part 122, and a third rotating part 123 from top to bottom. The diameter of the first rotating part 121 is larger than that of the second rotating part 122, and the diameter of the second rotating part 122 is larger than that of the third rotating part 123.

[0047] Among them, the first rotating part 121 is mounted on the upper skeleton oil seal 130, and the second rotating part 122 is sealed and connected to the rotating support sleeve 110 through the upper skeleton oil seal 130, the third rotating part 123 passes through the rotating support sleeve 110 and is connected to the pulley 180, and the third rotating part 123 is sealed and connected to the rotating support sleeve 110 through the lower skeleton oil seal 140, thereby ensuring the sealing performance between the die rotating sleeve 120 and the rotating support sleeve 110, ensuring that the cooling oil will not leak out when flowing through the bearing cavity 150, thereby ensuring good cooling and lubrication effects.

[0048] Furthermore, a first bearing 1221 is provided between the outer circumference of the second rotating portion 122 and the rotating support sleeve 110;

[0049] A second bearing 1222 is provided between the bottom surface of the second rotating portion 122 and the rotating support sleeve 110;

[0050] A third bearing 1231 is disposed between the outer circumference of the third rotating portion 123 and the rotating support sleeve 110 .

[0051] The arrangement of multiple bearings can better ensure the smooth rotation of the entire rotating structure, and good concentricity and stability can be guaranteed even at high-speed rotation.

[0052] Preferably, the cooling oil enters the bearing cavity 150 from the oil inlet channel 160, flows through the first bearing 1221, the second bearing 1222 and the third bearing 1231 in sequence, and then flows back to the oil cooler 200 along the oil outlet channel 170. This path design ensures that the cooling oil can evenly cover all bearings, which not only has a uniform cooling effect, but also can effectively lubricate each bearing, reduce friction and wear, and extend the service life of the bearings.

[0053] Preferably, a fourth bearing 181 is provided between the pulley 180 and the rotating support sleeve 110. The main function of the fourth bearing 181 is to support the rotation of the pulley 180. By reducing the friction resistance during the rotation of the pulley 180, the efficiency of power transmission can be improved, ensuring that the power is smoothly and efficiently transmitted to the die rotating sleeve 120.

[0054] The technical means disclosed in the scheme of the utility model are not limited to the technical means disclosed by the above technical means, but also include technical solutions composed of any combination of the above technical features. The above is a specific implementation method of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
