Problems solved by technology

[0003] As we all know, the joint between the spoke and the rim of the aluminum alloy wheel is large, which is the hot spot of the casting. Most wheels often have defects in this part, and most wheel manufacturers eliminate the defect of this hot spot by strengthening cooling, but Defects in this area are rarely completely eliminated

Embodiment

[0020] refer to Figure 1 to Figure 3 , a new wheel hub mold structure, including a bottom plate 1, a liquid suction pipe 2, a sprue sleeve 3, a bottom mold assembly 4 on the bottom plate 1, an upper mold assembly 100, a side mold assembly 200, and a side mold assembly 200 includes an upper side mold 9 and a lower side mold 7 that are movably connected.

[0021] After the upper mold assembly 100, the bottom mold assembly 4, and the side mold assembly 200 are molded together, a mold cavity is formed, and the casting 5 is located in the mold cavity.

[0022] An insert 8 is arranged between the parting surfaces of the upper mold 9 and the lower mold 7 .

[0023] Upper mold assembly 100 includes upper mold slide bar 10, upper mold 11, splitter cone 12, triangular block 13; dovetail guide slider 14; upper mold plate 15, ejector pin 16 guide column 17; ejector pin plate 18, ejector pin platen 19 .

[0024] One end of the insert 8 is inserted into the parting surface of the side m...

Abstract

The invention discloses a novel hub die structure. The novel hub die structure is characterized by comprising an upper die assembly, a bottom die assembly and an edge die assembly; a die cavity is formed after the upper die assembly, the lower die assembly and the edge die assembly are combined; the edge die assembly comprises an upper edge die and a lower edge die which are movably connected; an insert is arranged at a corresponding hot joint position and located at the position of a parting surface of the edge die assembly, one end of the insert is inlaid in the parting surface of the edge die assembly, and the other end of the insert extends in a casting hot joint; and the upper die assembly comprises an upper die plate and guiding pillars arranged on the upper die plate, and an ejector rod plate and an ejector rod pressing plate are arranged on the guiding pillars in a sleeving manner and move vertically along the guiding pillars. The novel hub die structure has the beneficial effects that the size of the hot joint of a casting spoke and a rim position is reduced, and the total weight of the product is reduced.

Description

technical field [0001] The invention relates to a low-pressure wheel hub casting mold, in particular to a novel wheel hub mold structure. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] As we all know, the joint between the spoke and the rim of the aluminum alloy wheel is large, which is the hot spot of the casting. Most wheels often have defects in this part, and most wheel manufacturers eliminate the defect of this hot spot by strengthening cooling, but Defects in this area are seldom completely eliminated. [0004] So the prior art needs to be improved and developed. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a new wheel hub mold structure that reduces the volume of hot nodes at the spokes and rims of castings and reduces the total weight of the product. [0006] The technical...
