[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0021] Please refer to Figures 1 to 4 , in the present utility model, a positioning mold for ultrasonic welding of batteries includes a mold block 1, a mold cavity 2 is formed on the mold block 1, four groups of elastic members 3 are installed inside the mold cavity 2, a carrier plate 4 is installed between the tops of the four elastic members 3, the outside of the carrier plate 4 is slidably installed inside the mold cavity 2, a vent hole 5 is formed on the carrier plate 4, an exhaust fan 6 is installed inside the mold block 1, and two exhaust slots 7 are formed on the mold block 1, and the air outlet side of the exhaust fan 6 is communicated with the two exhaust slots 7.

[0022] In this utility model, the mold block 1 serves as the main body of the device. The PC / ABS shell containing the battery is placed inside the mold cavity 2, and the cover part is snapped onto the PC / ABS shell. When the top ultrasonic welding device presses down to contact the cover part, pressure is generated to push the PC / ABS shell to press the carrier plate 4 at the bottom to slide down, and at the same time, the elastic member 3 at the bottom is squeezed to reach the lowest position. Then ultrasonic welding is carried out. After the welding is completed, the ultrasonic welding device rises, and the elastic member 3 at the bottom rises to lift the welded PC / ABS shell to expose the mold cavity 2. At the same time, the exhaust fan 6 at the bottom is turned on for rapid cooling.
