Abstract

The utility model relates to a casting aluminum alloy wheel field discloses side forms air discharge duct structure of aluminum alloy wheel mould, including the side forms, be provided with many V type air discharge ducts on the side forms, V type air discharge duct opening distance is 5-10mm, and affiliated V type air discharge duct groove is dark 1.5-4mm, V type air discharge duct V type angle is 100 degrees-150 degrees, and this structure can improve the exhaust problem of aluminium liquid at the side forms feeding in-process through the air discharge duct that increases the V type on the side forms of wheel mould, concentrates the top layer of foundry goods with impurity and gas in the aluminium liquid, can effectually reduce defects such as shrinkage porosity, compactness difference, pinhole that final finished product rim part appears.

Description

Side die exhaust groove structure of aluminum alloy wheel die

Technical Field

The utility model relates to a casting aluminum alloy wheel field, in particular to side forms air discharge duct structure of aluminum alloy wheel mould.

Background

The rapid development of the automobile industry drives the rapid growth of the automobile accessory market, and the differentiated requirements of the after-market corresponding to the automobile accessory market are more and more. The pursuit of automobile host factories is large-scale, homogeneous, high-quality and low-price accessories, and the pursuit of users is individual and differentiated accessories, which leads to more and more users to refit own automobiles. Aluminum alloy wheels are a typical accessory of many individualities and differences.

A common aluminum alloy wheel in the refitted market is a wheel with a large-size H-shaped rim structure, and the wheel with the structure has the remarkable characteristic that the inner rim and the outer rim are long, and the spoke is positioned between the inner rim and the outer rim and is H-shaped. Because the outer rim is specially shaped and protrudes more spokes, the rim part of the die is easy to have the defects of shrinkage porosity, poor compactness, pinholes and the like in the process of filling and feeding molten aluminum, thereby causing casting scrap.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide an aluminum alloy wheel die's side forms air discharge duct structure that can effectual reduction shrinkage porosity, compactness are poor, defect such as pinhole that final product rim part appears.

The utility model provides a technical scheme that its technical problem adopted is: the side die exhaust groove structure of the aluminum alloy wheel die comprises a side die, wherein a plurality of V-shaped exhaust grooves are formed in the side die, the distance of the opening parts of the V-shaped exhaust grooves is 5-10mm, the depth of the V-shaped exhaust grooves is 1.5-4mm, and the V-shaped angle of each V-shaped exhaust groove is 100-150 degrees.

Further, the method comprises the following steps: the distances between the V-shaped exhaust grooves are the same.

Further, the method comprises the following steps: the V-shaped exhaust grooves have different intervals.

Further, the method comprises the following steps: the plurality of V-shaped exhaust grooves are formed by lathing through a lathe.

The utility model has the advantages that: the exhaust duct of V type is increased through on the side forms of wheel mould to this structure, can improve the exhaust problem of aluminium liquid at the side forms feeding in-process, concentrates the top layer of foundry goods with impurity and gas in the aluminium liquid, can effectual reduction final finished product rim partial shrinkage porosity, compactness difference, pinhole defect such as appearance.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and fig. 2, the side mold 1 exhaust groove structure of the aluminum alloy wheel mold comprises a side mold 1, wherein a plurality of V-shaped exhaust grooves 2 are arranged on the side mold 1, the distance between the opening parts of the V-shaped exhaust grooves 2 is 5-10mm, the depth of the V-shaped exhaust groove 2 is 1.5-4mm, the V-shaped angle of the V-shaped exhaust groove 2 is 100-150 degrees, and the V-shaped exhaust grooves 2 are turned by a lathe, so that the exhaust problem of aluminum liquid in the feeding process of the side mold 1 can be improved by adding the V-shaped exhaust groove on the side mold 1 of the wheel mold, impurities and gas in the aluminum liquid are concentrated on the surface layer of a casting, the defects of shrinkage porosity, poor compactness, pinholes and the like of the final finished rim part can be effectively reduced, and the processing is more convenient and simpler due to the V-shaped structure, and the V-shaped groove is of a whole strip structure, so that the aluminum liquid slag absorption and slag collection effects are better, the gas storage is more, and the exhaust is smoother.

On the basis, the distances of the V-shaped exhaust grooves 2 are the same or different, and the specific distances can be designed according to actual conditions.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
