[0017] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0018] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a centrifugal casting floating oil seal ring composite mold provided by the utility model; Figure 2 for Figure 1 The overall external structural diagram of the centrifugal casting floating oil seal ring composite mold shown; Figure 3 for Figure 1A partial enlarged view of the area at center A. The centrifugally cast composite mold for a floating oil seal ring comprises a horizontally arranged circular mold base 1, with a mold cavity 14 defined transversely at the front end of the mold base 1. Multiple heat transfer holes 4 are defined transversely along the outer edge of the rear end surface of the mold base 1. A coaxial, hollow rotating ring 2 is rotatably connected to the outer surface of the mold base 1. The inner surface of the rotating ring 2 is defined by multiple liquid outlet holes 3 connected to its inner cavity. Each of the multiple heat transfer holes 4 has a liquid inlet hole 5 extending through the outer surface of the mold base 1 and corresponding to the multiple liquid outlet holes 3.

[0019] When the device is in operation, it is driven by the motor to rotate. Since the rotating ring 2 is installed on the outer surface of the mold base 1 through a rotating connection, the rotating ring 2 can remain stationary. After the molten metal is completely injected into the mold, the coolant is injected into the rotating ring 2, and then it enters the multiple liquid inlet holes 5 through the multiple liquid outlet holes 3 and flows into the temperature guide hole 4, so as to cool the casting in the mold, improve the cooling efficiency of the casting, and thus improve the overall processing efficiency.

[0020] The liquid inlet hole 5 and the outlet hole 3 only need to maintain relative positions to be able to communicate with each other for infusion, and the coolant will eventually flow out through the rear end of the temperature conducting hole 4.

[0021] A front cover 7 is detachably mounted on the front end of the mold base 1 , and a feed port 10 is formed in the middle of the front end surface of the front cover 7 and is formed transversely therethrough.

[0022] During processing, molten metal is injected into the feed port 10 , and as the device continuously rotates, an annular structure is formed under the action of centrifugal force.

[0023] The outer edge of the front end surface of the mold base 1 is laterally provided with multiple screw holes 6, and the front end surface of the front cover 7 is laterally provided with multiple connecting holes 8 corresponding to the multiple screw holes 6 respectively. The front cover 7 is detachably mounted on the front end surface of the mold base 1 by screws.

[0024] The front cover 7 is installed on the front end surface of the mold base 1 by screwing through multiple connection holes 9 and then tightening it inside the screw holes 6. In this way, the sealing of the connection between the front cover 7 and the mold base 1 can be ensured.

[0025] The outer surface of the rotating ring 2 is connected to a liquid inlet pipe 13 which is connected to the inner cavity thereof.

[0026] The coolant is fed into the interior of the rotating ring 2 through the liquid inlet pipe 13 .

[0027] Front ends of the plurality of connection holes 8 are expanded outward to form sinks 9 .

[0028] The recessed groove 9 has a fixing effect on the screws to prevent the screws from slipping after being tightened.

[0029] A connecting shaft 11 is transversely fixedly connected to the middle portion of the rear end surface of the mold base 1 , and a pulley 12 is fixedly connected to the outer surface of the connecting shaft 11 .

[0030] The device is mounted on other supporting structures via a connecting shaft 11 , and then driven to rotate by a motor and a driving pulley mounted thereon.

[0031] The working principle of the centrifugal casting floating oil seal ring composite mold provided by the utility model is as follows:

[0032] When the device is in operation, it is driven by the motor to rotate. Since the rotating ring 2 is installed on the outer surface of the mold base 1 through a rotating connection, the rotating ring 2 can remain stationary. After the molten metal is completely injected into the mold, the coolant is injected into the rotating ring 2, and then it enters the multiple liquid inlet holes 5 through the multiple liquid outlet holes 3 and flows into the temperature guide hole 4, so as to cool the casting in the mold, improve the cooling efficiency of the casting, and thus improve the overall processing efficiency.

[0033] Compared with the related art, the centrifugal casting floating oil seal ring composite mold provided by the utility model has the following beneficial effects:

[0034] The utility model provides a centrifugal casting floating oil seal ring composite mold, by providing a rotating ring 2, the device is driven to rotate by a motor when in operation, because the rotating ring 2 is prevented from being installed on the outer surface of the mold base 1 by a rotating connection, the rotating ring 2 can remain in a stationary state, after the molten metal is completely injected into the mold, the coolant is injected into the rotating ring 2, and then the coolant enters the multiple liquid inlet holes 5 through the multiple liquid outlet holes 3 and flows into the temperature guide hole 4, so as to cool the casting in the mold, improve the cooling efficiency of the casting, and thus improve the overall processing efficiency.
