Intra-mold automatic bonding stamping mold and process of stator and rotor iron cores

The invention discloses an intra-mold automatic bonding stamping mold and process of stator and rotor iron cores. The mold comprises an upper mold base and a lower mold base. Multiple independent lower sub-molds are arranged in the lower mold base. The lower sub-molds comprise non-heating sub-molds and heating sub-molds, the number of the non-heating sub-molds and the number of the heating sub-molds are at least one, the working temperatures of the heating sub-molds are higher than the normal temperature, and stamping cavities for blanking are formed in the heating sub-molds. A traditional buckle point laminated riveting structure or welding structure is changed into a coating bonding folding structure, iron losses are reduced, the performance of a motor is improved to the maximum degree,the size of the motor is reduced under the condition that the power is constant, and one-time automatic bonding folding forming in the mold is achieved. According to the process, the iron cores with coating materials are heat
