Abstract

The invention provides a motor shell of a new-energy vehicle,a sand core,a mold and a motor shell processing method,and relates to the technical field of motor shell casting. The motor shell comprisesa cylindrical main body,and a water channel is formed in the side wall of the main body; the water channel comprises multiple annular passages and connecting passages,the multiple annular passages are arranged at intervals in the depth direction of the main body,the connecting passages are connected between any two adjacent annular passages,and the connecting passages are used for making any twoadjacent annular passages communicated. By using the integrated sand core,in the die-cast formation process,the integrated water channel can be formed,welding or other combination modes are avoided,therefore,the sealing property is improved,and the water leakage problem can be solved. The integrated water channel exists in the inner wall of the main body,one-step molding is only needed for processing,and the production cost is low; the shell water channel is good in sealing property; the water circulation cooling effect is good,and reliability is high.

Description

technical field [0001] The invention relates to the technical field of motor casing casting, in particular to a motor casing, a sand core, a mold and a processing method for a motor casing of a new energy vehicle. Background technique [0002] The cooling water channel of the existing automobile motor casing realizes the casting of the circulating cooling water channel of the motor casing by the combination of inner and outer rings. Inner ring mold preparation, inner ring blank die-casting molding, inner ring blank die-casting molding, inner ring blank heat treatment and inner ring machining are required to prepare the inner sleeve. Outer ring mold preparation, outer ring blank die-casting molding, Outer ring blank die-casting, outer ring blank heat treatment, outer ring machining and other steps to prepare the jacket, and then the inner and outer rings are combined and welded into one. [0003] However, there are relatively large cost and safety problems in this method, sp...
