Preferably, a bearing is fitted onto the rotating shaft 22, and the bearing is fixedly mounted on the top of the support 1.
[0036] In addition, the drive mechanism 23 is fixed to the top of the bracket 1 and drives the rotating shaft 22, thereby enabling the mold fixing frame 21 to rotate. Preferably, the drive mechanism 23 is a stepper motor. The operator can control the stepper motor to rotate according to the situation, thereby driving the mold fixing frame 21 to rotate to a suitable angle and perform welding operations. During the rotation, the mold to be welded will not move, thus greatly improving the welding efficiency and welding effect.
[0037] In a specific embodiment of this utility model, the mold fixing frame 21 includes two longitudinal connecting rods 211 and two transverse connecting rods 212. The longitudinal connecting rods 211 and the transverse connecting rods 212 are arranged perpendicularly and are in the same plane. Since the welded mold needs to be kept entirely on a single plane, the longitudinal connecting rods 211 and the transverse connecting rods 212 are interlaced and fixedly arranged to ensure that they are in the same plane.
