Abstract
The invention belongs to the technical field of casting molds, and relates to a one-time casting and forming mold of a permanent magnet motor housing. One mold left-side movement die block, one mold right-side movement die block and one mold main movement die block are arranged on a casting mold base, and circled into a casting mold housing. A mold middle clay core, a mold water-way clay core, and a mold connecting box clay core are arranged inside the cavity of the casting mold housing. An interval is arranged between the outer wall of the mold middle clay core and the inner walls of the mold left-side movement die block, the mold right-side movement die block and the mold main movement die block to form the outer wall and the inner wall of the motor housing. Both terminal ends of the mold water-way clay core radially extend outward to connect with the inner wall of the mold main movement die block to form a liquid inlet and a liquid outlet of a cooling channel. The mold has the advantages of simple structure, easy molding, low production cost, high production efficiency, good quality products, and is suitable for integral casting of the housing of a high power permanent magnet motor having the cooling channel.
