Description
Technical Field
The utility model relates to a casting technical field, especially a compound cooling structure of aluminum alloy wheel hub mould.
Background
Aluminum alloy hubs which are widely used are mostly prepared by a fusion casting method. The aluminum alloy hub die comprises an upper die, a lower die, a side die and an upper die core which are matched with each other, wherein the side die comprises a side die body and a water-cooling insert, and the lower die, the side die, the upper die and the upper die core are matched to form a die cavity for casting a rim part of a hub blank. In the casting process, the cooling of the mold is very important, which not only affects the internal quality of the casting, but also affects the production efficiency and the processing and manufacturing cost. However, the cooling device in the prior art is generally single air cooling, water mist cooling or water cooling, and in terms of cooling capacity, the water cooling is the best, the water mist cooling is the second, and the air cooling is the worst, but the single cooling mode is adopted, so that the solidification sequence of the casting cannot be controlled in a targeted manner according to the shape characteristics of the hub, and if the material cannot be supplemented at the post-solidification position, the problems of shrinkage, looseness and the like occur, and the product is scrapped.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a composite cooling structure of an aluminum alloy wheel hub die.
The utility model provides a technical scheme that its technical problem adopted is:
a composite cooling structure of an aluminum alloy hub die comprises an upper die, a lower die and side dies, wherein a die cavity is formed among the upper die, the lower die and the side dies, and comprises a rim die cavity, a spoke die cavity and a flange die cavity;
a water mist cooling pipeline is arranged at the position, corresponding to the flange plate die cavity, of the upper die, and water mist spray heads are distributed on the water mist cooling pipeline and face the flange plate die cavity;
a lower die water cooling pipeline is arranged at the position, corresponding to the die cavity of the flange plate, in the lower die;
a side die water-cooling insert is arranged in the side die at a position corresponding to the rim die cavity, and a side die water-cooling pipeline is arranged in the side die water-cooling insert;
and an upper die air cooling pipeline is arranged at the position of the upper die corresponding to the spoke die cavity and the rim die cavity, and a lower die air cooling pipeline is arranged at the position of the lower die corresponding to the spoke die cavity.
The utility model has the advantages that: the advantages of different cooling strengths can be integrated, three-dimensional composite water cooling is realized, the mold manufacturability is optimized, and cooling modes with different requirements are provided for different positions.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1, the composite cooling structure of the aluminum alloy hub mold comprises an upper mold 10, a lower mold 20 and a side mold 30, wherein a mold cavity is formed among the upper mold 10, the lower mold 20 and the side mold 30, and comprises a rim mold cavity 41, a spoke mold cavity 42 and a flange mold cavity 43, namely after the upper mold 10, the lower mold 20 and the side mold 30 are closed, the mold cavity is formed and is used as a casting mold cavity of a hub to be cast.
The flange of wheel hub belongs to half strong region, and the cooling intensity that is half strong region should not too strong also should not too weak, consequently, goes up mould 10 and corresponds flange die cavity 43 position department and is provided with water smoke cooling pipeline 50, and water smoke shower nozzle distributes on the water smoke cooling pipeline 50 towards flange die cavity 43 for half strong region such as aluminium alloy wheel hub back flange.
A lower die water cooling pipeline 60 is arranged in the lower die 20 at the position corresponding to the flange plate die cavity 43. The position of the lower die 20 corresponding to the flange plate die cavity 43 is close to the die gate, the position is a hot final solidification area of casting, and the cooling strength needs to be increased, so the lower die is cooled by adopting a water cooling mode of a lower die water cooling pipeline 60. The side die 30 is provided with a side die water cooling insert 70 at a position corresponding to the rim die cavity 41, and a side die water cooling pipeline is arranged in the side die water cooling insert 70. The position of the side mold 30 corresponding to the rim mold cavity 41 is the position of the mold side mold hot junction, and the cooling strength needs to be increased, so that a water-cooling insert is selected for cooling. The concrete shapes of the side die 30 and the side die water cooling insert 70 are determined according to the shape and the model of the hub, and refer to the die-casting die of the same hub.
An upper die air cooling pipeline 80 is arranged at the position, corresponding to the spoke die cavity 42 and the rim die cavity 41, of the upper die 10, and a lower die air cooling pipeline 90 is arranged at the position, corresponding to the spoke die cavity 42, of the lower die 20, namely, the positions are cooled in an air cooling mode.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
