Detailed Description
As shown in fig. 1-4, an aluminum alloy hub casting mold capable of saving raw materials comprises a mold body, wherein the mold body comprises a side mold 1, an upper mold 2 and a lower mold 3, the side mold 1, the upper mold 2, the lower mold 3 and a mold closing form a hub casting cavity 5, and the side mold 1 and the side wall of the upper mold 2 are mold closed to correspond to a rim part 4 of a hub. The novel wheel hub blank is characterized by further comprising a weight reduction structure corresponding to the die body, wherein the weight reduction structure is used for improving the problems that the rim part 4 of the existing wheel hub blank is too thick, aluminum materials are wasted and the turning workload is increased by adjusting the side wall structure of the side die 1 and/or the side wall structure of the upper die 2.
First embodiment:
the weight reduction structure comprises a side die 1 and an upper die 2, the distance between the side die 1 and the side wall of the upper die 2 is shortened to form a smaller casting cavity 5, so that a hub blank with a thinner rim part 4 is obtained, and the purpose of reducing aluminum consumption is achieved. The distance between the side die 1 and the side wall of the upper die 2 is generally set to be about 4mm of the thickness of the hub finished rim portion 4, in this embodiment, the distance between the side die 1 and the side wall of the upper die 2 is set to be 2.5-3mm larger than the thickness of the hub finished rim portion 4, so that the reserved thickness of the hub blank rim portion 4 is 1-1.5mm thinner, aluminum consumption is reduced, the single weight of a hub blank is reduced, and the workload of machining procedures is reduced.
As a preferable embodiment, the distance between the side die 1 and the side wall of the upper die 2 is increased by 2.6mm based on the thickness of the hub finished rim part 4, so that the thickness of the rim part 4 of the hub blank is reduced to the greatest extent while the feeding effect of the aluminum liquid is ensured.
Second embodiment:
the weight-reducing structure comprises weight-reducing ribs 11 arranged on the side wall of the side die 1, wherein the weight-reducing ribs 11 protrude out of the side wall of the upper die 2 and are arranged at intervals corresponding to the side wall of the upper die 2. After the side die 1 and the upper die 2 are matched, the weight-reducing rib 11 invades the cavity 5 and occupies the space of the cavity 5, and the weight-reducing rib 11 forms a groove corresponding to the weight-reducing rib 11 at the rim part 4 of the hub blank in the casting process. In this embodiment, the weight-reducing rib 11 penetrates into the cavity 5, that is, the hub to reduce the aluminum consumption, thereby achieving the purpose of reducing the aluminum consumption. Compared with the first embodiment, the arrangement of the weight-reducing rib 11 keeps the aluminum liquid feeding channel to a larger extent under the condition of not changing the side wall spacing between the side die 1 and the upper die 2, and achieves the weight-reducing effect under the condition of less influence on the feeding channel.
