MANUFACTURE OF MONO-BLOCK BATTERY JAR

摘要

PURPOSE:To manufacture a mono-block battery jar capable of being molded while the flow of resin is balanced. CONSTITUTION:A die 6 is used having the structure provided with a battery jar outer wall molding chamber 2a molding a battery jar outer wall, a battery jar bottom plate molding chamber 3a molding a battery jar bottom plate, and a cell bulkhead molding chamber 4a molding cell bulkheads. Passage resisting bodies 8 serving as resistance against the flow of resin are arranged in the battery jar bottom plate molding chamber 3a ranging to the battery jar outer wall molding chamber 2a from a resin injection gate 7 adjacent to the battery jar outer wall molding chamber 2a, and a mono-block battery jar is molded.
