Title:
COOLING STRUCTURE OF CAST-ON-STRAP MOLD FOR BATTERY
Document Type and Number:
WIPO Patent Application WO/2014/142380
Kind Code:
A1
Abstract:
The present invention provides a cooling structure of a cast-on-strap mold for a battery, the cooling structure comprising a mold main body having runner blocks at both sides thereof to supply molten lead, having a strap cavity at an upper side thereof to fill the molten lead, and having a central mold cooling channel and a lower cavity cooling channel at an inner side thereof for cooling; and a lower mold plate having a cooling channel connection pipe coupled to the lower side of the mold main body to connect all of the cooling channels, wherein an extension part is formed on a lateral surface of the mold main body, which is adjacent to the runner block, a boundary cooling channel is formed within the extension part, and an intermediate cooling channel is formed between the central mold cooling channel and the lower cavity cooling channel, so that each part of straps is uniformly and more rapidly cooled. Further, the present invention has an effect in that generation of cracks caused due to stresses can be minimized by reducing a difference between crystal structures of the parts of the straps by allowing the parts of the straps to have a uniform cooling temperature when the straps are formed. Further, the present invention is very useful in that a uniform temperature can be maintained even while in standby, so that even when the molten lead is introduced into the strap cavity, cooling of the straps can be induced while overall balance is maintained, and especially, an excellent productivity effect can be expected by minimizing a cooling period of the straps (in the case of the present invention, the cooling period of the straps is about 12 seconds, so productivity is expected to improve by two or more times during the same time).
