The utility model discloses a mould hoisting structure for a permanent magnet jack, which comprises a cross beam and a mould to be transported, and further comprises a hoisting reinforcing mechanism, the hoisting reinforcing mechanism comprises a second electric telescopic rod arranged on the cross beam, the fixed end of the second electric telescopic rod is provided with a connecting rod, and the fixed end of the second electric telescopic rod is provided with a clamping groove; the other end of the connecting rod is connected with a permanent magnet lifting module, an air bellow is arranged at the end, away from the connecting rod, of the fixed end of the second electric telescopic rod, and the air bellow and the permanent magnet lifting module act together. And the auxiliary protection mechanisms are arranged on the outer walls of the two sides of the cross beam. The mold hoisting structure for the permanent magnet jack has the technical effects that the adsorption effect is improved, magnetic force borne by all parts of an object to be transported is uniform, firm adsorption and safe hoisting are ensured, and meanwhile, local deformation or damage of a mold to be transported caused by uneven stress is also avoided.

The utility model relates to the technical field of servo motor accessories, and discloses a stator wheel structure for a servo motor, which comprises a motor stator, the front end and the rear end of the motor stator are fixedly connected with clamping sleeves, the left end of the motor stator is clamped with a fixed cover, and the left end of the fixed cover is provided with a plurality of heat dissipation holes. Clamping blocks are fixedly connected to the front side and the rear side of the right end of the fixed cover, the outer walls of the clamping blocks are clamped to the inner wall of a clamping sleeve, the clamping blocks and the clamping sleeve are connected through bolts, a plurality of stator slot wedges are formed in the inner wall of the motor stator, and magnet exciting coils are wound around the outer walls of the stator slot wedges. According to the utility model, the two clamping blocks at the right side of the fixing cover are inserted into the clamping sleeve and are matched with the fixing bolts, so that the fixing cover can be installed at the left end of the motor stator, and guiding and limiting effects are achieved for subsequent installation of the motor rotor, so that the installation is more accurate and convenient; meanwhile, the left end of the fixed cover is provided with a plurality of heat dissipation holes for air circulation, and the heat dissipation holes are prevented from affecting normal heat dissipation of the structure.
