Problems solved by technology

However, due to the existing water-cooled aluminum alloy cast wheel molds, a cooling channel is opened inside the mold, and cooling water is injected into the cooling channel to cool the aluminum alloy cast wheel hub. Since water has a corrosive effect on the mold, the use of After a long time, the mold is in contact with the air, causing the mold to rust

Abstract

The invention discloses a hub manufacturing method. An upper air cylinder and a lower air cylinder act, a bottom die and a top die are controlled to get close to a casting hole, a both-way air cylinder acts, each set of oppositely-arranged side dies are controlled to synchronously get close to the casting hole, and the bottom die, the top die and the side dies are mutually pressed to form a hub casting cavity. A casting machine pours liquid molten aluminum into a cavity of a casting die for filling. The lower air cylinder acts, a lower support drives the bottom die to evacuate, a hub supporting rod enters a feeding rail from a walking rail and enters the position below the bottom die from the feeding rail, the top die moves upwards under the action of the upper air cylinder, each set of oppositely-arranged side dies are opened at the same time, and a hub falls onto the hub supporting rod. A water pump conveys cooling water into a circular pipe through a water pipe, the cooling water is sprayed to the outer side edge of the hub through a sprayer on the circular pipe, and the circular pipe reciprocates up and down along a guiding column. After cooling is finished, the hub moves to one end of a discharging rail through the feeding rail along with the hub supporting rod, and the hub is conveyed away through the discharging rail.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a wheel hub manufacturing method. Background technique [0002] The casting process of aluminum alloy wheels includes the following steps: the mold needs to be installed on the casting machine, the mold is clamped, and aluminum water is poured into the mold cavity; after the casting is completed, the wheel hub needs to be cooled; after the cooling is completed, the mold is opened, and the wheel hub take out. However, in the existing wheel hub casting process, the degree of automation is not high, and the degree of manual participation is high. In addition, during the casting process of the aluminum alloy wheel, after the pouring of the aluminum alloy wheel is completed, the aluminum alloy wheel needs to be cooled. The molds of the existing low-pressure casting molding technology generally have compressed air cooling and water cooling. For example, the Chinese utility model whose publi...
