Casting mould for car chassis shell

Abstract

The invention relates to a casting mould for a car chassis shell. The casting mould comprises a lower box, an upper box, a box cover and a slope adjusting body; the slope adjusting body is mounted atthe bottom of the lower box in a wedge shape, the top of the lower box is covered with the upper box, and the box cover is mounted between the upper box and the lower box; and an outer pouring openingis formed in the upper box and the box cover and formed in the side close to the large end of the slope adjusting body. The casting mould adopts the lower box, the upper box, the box cover and the slope adjusting body, and a detachable whole is formed through the structures of the lower box and the upper box; the pouring opening is formed in the upper box and the box cover by adopting the slope adjusting body, molten iron is injected into the pouring opening, by utilizing the nature of the molten iron and combining the inclined shape of the bottom of the lower box, the molten iron is sunken,and gas bubbles in the molten iron rise upwards; and through the slope adjusting body, the molten iron in the mould is sunken completely, gas in the molten iron can be exhausted completely, and thus the problems that gas holes are formed in the surface of the casted shell, and consequently, the yield of the car chassis shell is affected, and the production efficiency is low are prevented.

Description

technical field [0001] The invention relates to the technical field of sand casting equipment, more specifically, it relates to a casting mold for an automobile chassis shell. Background technique [0002] As the core component of the vehicle, the automobile chassis is equipped with a transmission system, a driving system, a steering system and a braking system. As an important part of the automobile chassis, the production and processing of the automobile chassis shell has attracted more and more attention. [0003] At present, the production of automobile chassis shells generally adopts the iron mold sand-coated or clay sand process. During the casting process, a large amount of gas is not easy to get rid of, and a large number of waste products are formed after the casting is cooled. The cost of the mold is high, and the yield rate is only 60%- -75%. [0004] Therefore, for above-mentioned technical problem, be badly in need of inventing a kind of automobile chassis she...
