[0024] like Figures 1 to 3 As shown, a universal lead-acid battery terminal welding mold includes a mold base 1 and a detachable terminal mold 2. The mold base 1 has a welding cavity 11 extending vertically therethrough. The welding cavity 11 is open on both the upper and lower surfaces of the mold base 1. The lower surface opening is for inserting the terminal for welding, and the upper surface opening is for the flame ejected from the welding torch to contact the terminal during welding.

[0025] The removable terminal mold 2 is removably mounted within the welding chamber 11. It has a terminal hole 21 extending vertically therethrough. The size of the terminal hole 21 matches the shape of the terminal to be welded. The terminal hole 21 has a certain taper, generally larger at the bottom and smaller at the top, with a taper of 1:9.

[0026] The top surface of the detachable terminal post mold 2 is tilted downward from close to the terminal post hole 21 to away from the terminal post hole 21. In this way, any excess lead liquid that may be produced will flow outward along the top surface of the detachable terminal post mold 2, and will not adhere to the outer peripheral surface of the terminal post.

[0027] The welding cavity 11 of the mold base 1 is smaller at the bottom and larger at the top. Correspondingly, the outer circumference of the detachable terminal column mold 2 is also smaller at the bottom and larger at the top. The detachable terminal column mold 2 is snap-fitted and installed in the welding cavity 11. The snap-fitting method facilitates installation and removal between the two. When installing, it is only necessary to place the detachable terminal column mold 2 into the welding cavity 11 of the mold base 1 and snap it in. When removing, the universal lead-acid battery terminal column welding mold of the present application is turned upside down and the detachable terminal column mold 2 is removed from the welding cavity 11.

[0028] The welding chamber 11 comprises a mounting portion at the bottom that cooperates with the detachable end column mold 2, and a bell mouth portion at the top that has a sidewall slope greater than that of the mounting portion. The bell mouth portion facilitates the operation of the welding gun during welding.

[0029] The bottom surface of the mold base 1 also features a downwardly projecting raised ring 12 surrounding the bottom opening of the welding cavity 11. The presence of raised ring 12 prevents other portions of the bottom surface of the mold base 1 from directly contacting the plastic portion of the lead-acid battery cover during welding, thus preventing damage to the lead-acid battery cover. The bottom surface of the mold base 1 also features a chamfer 13 at the bottom opening of the welding cavity 11 to facilitate insertion of the terminal post.

[0030] A cooling water channel 14 is provided inside the mold base 1. The cooling water channel 14 is arranged in a circle around the mold base 1, but the circle is not completely connected, which is equivalent to a partition wall in the circle. A water inlet 15 and a water outlet 16 are provided on the outer wall of the mold base 1 for water to enter and exit the cooling water channel 14. The water inlet 15 and the water outlet 16 are arranged adjacent to each other, and the water inlet 15 and the water outlet 16 are respectively located on both sides of the partition wall. The water inlet 15 and the water outlet 16 are connected to the water inlet pipe and the water outlet pipe respectively when in use, and cooling can be achieved quickly by water cooling. After the circulating cold water is introduced, it will flow in one direction, and the heat of the entire end and column will be evenly dissipated as the water circulates.

[0031] A hand-held handle 3 is provided on the side of the mold base 1 for easy operation by the operator. A water inlet 15 and a water outlet 16 are located on both sides of the hand-held handle 3 respectively.

[0032] When in use, first select a suitable detachable terminal column mold 2 and install it in the welding cavity 11 of the mold base 1, and then perform welding. According to the specifications of the terminal column to be adapted, a detachable terminal column mold with a corresponding size terminal column hole is selected, and the mold base is a universal structure and does not need to be replaced.
