Title:
RUNNER BLOCK HAVING UNIFORM DISCHARGE RATE OF MOLTEN LEAD
Document Type and Number:
WIPO Patent Application WO/2014/175491
Kind Code:
A1
Abstract:
Provided is a runner block having a uniform discharge rate of molten lead, the runner block having horizontal inner and outer conduits in the interior thereof for supplying molten lead, supplied by means of a molten lead inflow conduit, to a molten lead flow channel, and having a plurality of molten lead discharge holes, in communication vertically, on the inner and outer conduits, wherein the diameters of the molten lead discharge holes on the inner and outer conduits get increasingly smaller moving from the front end to the rear end thereof. As to the effects of the present invention, the molten lead from all molten lead discharge holes is discharged at a uniform rate, thus allowing a set level of molten lead to be maintained in the molten lead flow channel of the runner block when molten lead flow channel thereof is being filled with molten lead, thereby leading to the filling and cooling rates of the molten lead in the mold well to be uniform and to the reduction in the variance of the crystalline structure of each strap, and thus the marketability of the battery product can be enhanced with the present very useful invention.
