In the battery terminal, in order to reduce unnecessary protrusion of the strap as much as possible, it is desirable that the area of the pole column side surface continuous with the strap outer peripheral surface be large. For example, when the pole is formed in a cylindrical shape, the outer peripheral surface of the strap may be continuous with a half circumference of the side surface of the pole. In order to manufacture this battery terminal, in the casting apparatus of the present invention, it is preferable that the surface of the weir facing the cavity is continuous with half the circumference of the pole column forming portion.
In the casting apparatus of the present invention, the cooling means provided around the pole column forming portion includes a cooling water circuit and a water jacket. As the material of the weir, for example, copper can be used, or a copper alloy may be used. Further, cast iron can be used as a material of the mold.
