[0024] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Refer to Figures 1 to 4 , the present utility model discloses an exhaust plug assembly structure for an aluminum alloy wheel mold, including:

[0026] A mold 1, on which a plurality of exhaust block mounting positions are circumferentially and equally spaced. An exhaust block structure 2 is mounted on the exhaust block mounting positions. An installation hole 202 is formed on the exhaust block structure 2, and an exhaust plug structure 3 is in interference fit with the inner side of the installation hole 202.

[0027] In the present utility model, an installation hole 202 is drilled at the exhaust end of the exhaust block structure 2, and the exhaust plug structure 3 is directly installed in interference fit with the inner side of the installation hole 202, canceling the exhaust plug welding process, making the appearance of the mold neat, reducing the production cost of the mold, and significantly improving the replacement efficiency of the exhaust plug 301, the labor intensity, and the exhaust performance of the exhaust plug 301.

[0028] In a further optimized solution, the exhaust block structure 2 includes an exhaust block body 201 fixedly connected to the exhaust block mounting position. The exhaust block body 201 is successively provided with an air inlet 203 and an exhaust cavity 204 along the gas discharge direction. The air outlet end of the exhaust cavity 204 is communicated with the air inlet end of the exhaust plug structure 3 located inside the installation hole 202.

[0029] In a further optimized solution, the caliber of the air inlet end of the air inlet 203 is smaller than the caliber of the air outlet end of the air inlet 203, and the caliber of the air outlet end of the air inlet 203 is equal to the caliber of the air inlet end of the exhaust cavity 204.

[0030] In a further optimized solution, a necking treatment is performed between the air inlet end and the air outlet end of the air inlet 203.

[0031] When the gas flows through the necking part, the flow rate increases, which can improve the exhaust efficiency.

[0032] In a further optimized solution, a circular ring baffle 205 is fixedly connected to the inner side of the air outlet end of the exhaust cavity 204, and a cavity is formed between the circular ring baffle 205 and the installation hole 202.

[0033] For a further optimized solution, the exhaust plug structure 3 includes a gasket 303, a copper sleeve 302, and an exhaust plug 301 arranged in sequence along the gas discharge direction;

[0034] The gasket 303 is placed on the circular ring baffle 205 and is clamped into the cavity. The copper sleeve 302 is in contact with the gasket 303 and is press-fitted inside the mounting hole 202, and the exhaust plug 301 is press-fitted and nested inside the copper sleeve 302.

[0035] The cavity is used to hold the circular ring baffle 205.

[0036] For a further optimized solution, a plurality of exhaust channels 3011 are provided at the gas outlet end of the exhaust plug 301, and the plurality of exhaust channels 3011 are evenly and equally spaced. The setting of the exhaust channels 3011 can further improve the exhaust efficiency.

[0037] When the present utility model is in use, first install the gasket 303, then insert the copper sleeve 302 (the press-fit ensures reliable installation and eliminates welding), and finally insert the exhaust plug 301. When disassembling, use an iron rod from the back cavity to eject the exhaust plug structure 3. The replacement is simple, and rapid installation and disassembly can be achieved.
