Problems solved by technology

However, the existing casting process has the following defects: first, the local material is too thick during casting, which is prone to castability problems such as shrinkage cavities and looseness; second, the amount of turning chips is large during processing, and there is a lot of material waste

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] refer to Figure 1 to Figure 3 , a core-pulling casting mold for an aluminum alloy wheel hub, comprising a lower mold 5, a side mold 4 and an upper mold 1 that are combined to form a wheel hub casting cavity, and any adjacent two rib window elevation slopes 6 of the lower mold 5 are provided An insert 3 is arranged, and the insert 3 is in an arc-shaped structure, which just matches the inner surface of the formed C-ring of the hub.

[0016] A core-pulling casting process for an aluminum alloy wheel hub. The casting process includes: in the early stage of casting, placing a set of preheated inserts 3 on the corresponding position of the lower mold 5, and then closing the mold to start casting; the demoulding stage: when the mold is opened, The insert 3 is taken up by the upper mold 1 together with the wheel hub, and after demolding, the insert 3 is rem...

Abstract

The invention relates to the technical field of hub manufacturing, in particular to an aluminum alloy hub core pulling casting mold and a process thereof. The mold comprises a lower mold, a side moldand an upper mold which are combined to form a hub casting mold cavity; an insert is arranged between two adjacent rib window backward slanting faces of the lower mold, and is of an arc structure, andthe insert is right matched with the inner side face of a hub C ring. The insert is arranged on the lower mold of the hub, the insert is used for replacing an aluminum profile added newly in a C ringin the prior art, the demolding angle is ensured, demolding is facilitated, meanwhile, the weight of a hub rough material is reduced by about 5.3 kg, the aluminum material for casting a workblank issaved, cost is saved, damage of a machining tool is reduced, meanwhile, market needs of light weight and individuation are met, and the excellent market value and economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of wheel hub manufacturing, in particular to an aluminum alloy wheel hub core-pulling casting mold and a process thereof. Background technique [0002] The wheel hub of a kind of special-shaped tire ring that is developed now (see attached figure 1 ), the air nozzle of this type of hub is installed at the corner of B and C rings, while the air nozzle of the existing hub is in the rib window of D ring. According to the existing casting process, the inner tire ring of the wheel rim needs to follow a certain demoulding angle to achieve smooth demoulding. However, the C-ring part of this wheel hub protrudes from the upper mold, so demoulding cannot be achieved during casting. To achieve demoulding, only the wheel can be added. The aluminum material at the ring C is made to make its position consistent with the angle of the B ring and connected smoothly, and then the added material is turned during processing to...
