Embodiment Construction

[0008] see figure 1 , the present invention comprises a bottom mold 4 and a side mold 3, a splitter cone 5 is housed in the middle of the bottom mold 4, an upper mold 1 cooperating with the bottom mold 4 is housed in the side mold 3, the upper mold 1, the side mold 3 and the bottom mold 4 A cavity 6 is formed between them; in particular: two high-frequency vibration devices 2 are arranged outside the side mold 3, and the vibrating heads of the high-frequency vibration devices 2 are arranged directly opposite the side mold 3, which constitutes the present invention.

[0009] The size, specification and material selection of upper mold 1, high-frequency vibration device 2, side mold 3, bottom mold 4, splitter cone 5 and cavity 6 of the present invention can be adjusted according to actual needs, and these adjustments are not substantial. Changes in principle all belong to the protection scope of the present invention.

Abstract

The invention discloses an aluminum alloy wheel hub gravity casting mould, which comprises a bottom die and a side die. A shunting cone is mounted in the middle of the bottom die, an upper die cooperating with the bottom die is mounted in the side die, and the upper die, the side die and the bottom die together form a cavity. The device is characterized in that: the side die is externally provided with several high-frequency vibration devices, the vibration heads of which are over against the side die. The mould provided by the invention can reduce or eliminate ventilation micropores in aluminum alloy wheel hubs, simultaneously strengthens the deslagging ability of liquid aluminum and improves the texture density and mechanical properties of casts, so that the produced aluminum alloy wheel hubs have improved quality. The aluminum alloy wheel hub gravity casting mould is mainly used as the casting mould for production of aluminum alloy wheel hubs.

Description

technical field [0001] The invention relates to a mold for manufacturing an aluminum alloy wheel hub, in particular to a gravity casting mold for an aluminum alloy wheel hub. Background technique [0002] The traditional aluminum alloy wheel hub gravity casting mold includes a bottom mold and a side mold. There is a splitter cone in the middle of the bottom mold, and an upper mold that cooperates with the bottom mold is installed in the side mold. A shaped mold is formed between the upper mold, the side mold and the bottom mold. cavity. Since the aluminum alloy has a serious tendency to oxidize and absorb gas, and it is directly in contact with the furnace gas or the outside atmosphere during the pouring process, it often causes the aluminum alloy to absorb gas to form ventilating micropores, which will cause the production of aluminum alloy wheel hub gravity casting molds. The density of the casting structure is reduced, the mechanical properties are reduced, the quality i...
