<p>The present invention provides a structure of a cast-on-strap mold for a battery for supplying molten lead having a uniform temperature in order to perform stable strap-welding during strap forming and discharging collected molten lead through a runner block. The present invention has effects that molten lead introduced into a mold cavity in order to form a strap can be continuously supplied while maintaining a uniform level, thereby making the temperature and the calorie of the molten lead stable and thus enabling the strap to be casted at a constant speed. As a result, the entire tissue of the strap becomes uniform and there is nearly no difference between weights of the straps, thereby improving the marketability of the battery. Further, the present invention is very useful in that, since the molten lead can be collected not through the mold but through a runner block which is always in a high temperature state, it is unnecessary to install a separate heating device for preventing hardening of the molten lead and the mold does not require a separate space for collecting the molten lead, thereby minimizing the size of the mold and enabling the mold to be easily manufactured.</p> |
