Cooling device for automobile parts

Abstract

The invention discloses a cooling device for automobile parts, and belongs to the field of cooling of the automobile parts. The cooling device comprises a rotating ball, two connecting cross rods are fixed on the surface of the rotating ball, the two cross rods penetrate through two conical grooves respectively, second sliding grooves are formed in the lower surfaces of the two cross rods, second sliding blocks are slidably connected into the second sliding grooves, the two second sliding blocks are connected with the same clamping device, the two second sliding blocks and the side walls of the second sliding grooves are fixedly connected with clamping springs, a cooling groove is formed in the upper surface of a bottom plate, and an inflation connector is formed in the bottom of the cooling groove. According to the cooling device, the inflation connector is arranged at the bottom of the cooling groove, when the automobile parts enter the cooling groove, cooling liquid enters through holes of the parts, after the inflation connector communicates with the through holes, residues in the through holes and the cooling liquid are blown out together, the cooling liquid has the scouring effect on the residues, meanwhile, the inflation connector blows out the cooling liquid in the through holes, and internal corrosion of the automobile parts caused by residual cooling liquid can be prevented.

Description

technical field [0001] The invention belongs to the field of auto parts cooling, in particular to a cooling device for auto parts. Background technique [0002] In the process of automobile manufacturing, there are many parts made of cast iron, accounting for about 10% of the weight of the whole vehicle, such as cylinder block, transmission case, steering gear housing, rear axle housing, brake drum, various brackets, etc. . Casting is a production method in which molten metal is poured into the cavity of a mold and cooled and solidified to obtain a product. Sand molds are usually used to manufacture iron castings. The raw material of the sand mold is mainly sand, which is mixed with binder and water. The sand mold material must have a certain bonding strength so that it can be molded into the desired shape and can resist the scour of high-temperature molten iron without collapsing.

AI Technical Summary

Problems solved by technology

[0003] When cooling casted auto parts, since the parts usually have through holes and cavities, after the cooling is completed, there will be residual coolant and residues in the through holes and cavities that are difficult to clean up, which will affect normal use. Under the circumstances, when the coolant remains in the through hole, most of them adopt the static method to let the coolant flow out and evaporate naturally. This method takes too long and is inefficient. The residual coolant and residue in the through hole of the auto parts will seriously Affect the use of parts, and when the parts are installed on the car, there will be serious safety hazards
