Embodiment Construction

[0019] The present invention as figure 2 shown.

[0020] A pouring system for a wheel hub. The outer structure of the wheel hub is divided into a first step 1, a second step 2, a flange 3 and a straight cylinder 4 in sequence, and the interior is provided with a bearing installation position 5, and the flange 3 is provided with a mounting groove. 6. A feeding riser 7 is provided on the outer circle of the second step 2, and the feeding riser 7 is connected to the sprue 9 through the runner 8.

[0021] There is a distance between the 7 roots of the feeding riser and the 3 flanges, and the distance is 3-5mm.

[0022] Fractures 10 are also provided on the root of the feeding riser 7 and the second step 2 .

Abstract

The invention provides a hub casting system. The exterior of a hub is structurally divided into a first step, a second step, a flange and a straight barrel in sequence, and a bearing mounting position is arranged in the hub in a penetration way, wherein a mounting groove is formed in the flange; a feeding head is arranged on the outer circle of the second step, and is connected with a straight runner through a transverse runner; a gap is formed between the root of the feeding head and the root of the flange, and is 3 to 5mm; a fracture is formed in the root of the feeding head and the second step. According to the hub casting system, the casting position of a casting is shifted to a position to be fed, that is, the feeding head is shifted to the second step on the flange, the feeding head is directly used for feeding to the second step, the straight runner and the transverse runner are continuous, and the casting is cast by virtue of the feeding head, so that the defect of shrinkage is substantially eliminated, and a result meets the requirement of a product.

Description

technical field [0001] The invention relates to a casting structure of auto parts, in particular to a pouring system of a wheel hub. Background technique [0002] The outer structure of the wheel hub in the auto parts is divided into a first step 1, a second step 2, a flange 3 and a straight cylinder 4 in sequence, and a bearing installation position 5 is provided through the interior, and a mounting groove 6 is provided on the flange. Such as figure 1 shown. [0003] At present, under the traditional method, the gating system design of the hub generally adopts the following scheme: [0004] Solution 1: In order to have a relative feeding of the second step 2 and the straight cylinder 4 on both sides of the flange 3, especially the shrinkage cavity / looseness will occur at the root of the flange 3 and the step 2, so the casting method of the hub will be adopted There is a thermal feeding shrinkage riser at the outer circle of Lan 3, so that the molten iron can pass through...
