Abstract

본 발명은 냉간 단조형 금형에 관한 것으로서 특히 금형내에 있는 금형 다이이와 보강링 사이에 서브링을 주연 설치함과 동시에 이 서브링의 60°방향으로 수개의 슬림흠을 형성하여 금형 다이내에 고온의 소재를 주입할시 발생되는 응력을 보다 효과적으로 흡수할 수 있게 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cold forging dies. In particular, a sub-ring is formed between a die die and a reinforcing ring in the mold, and several slim grooves are formed in the 60 ° direction of the sub-ring, thereby forming a high temperature material. It is to be able to more effectively absorb the stress generated when the injection.

더욱 상세하게는 성형 공간에 고온의 소재물을 주입하게 되면 금형 다이의 외주연에 발생되는 고온의 열은 서브링에 형성된 슬립홈으로 방출하게 된다. 따라서 서브링이 금형 다이의 응력을 보다 효과적으로 흡수하게 되어 빠른 시간내에 제품이 성형됨은 물론 제품이 성형됨은 물론 제품을 축출할시 성형 공간의 일부나 혹은 전부가 파손되지 않는 등의 특징있는 발명이다.More specifically, when a high temperature material is injected into the molding space, the high temperature heat generated at the outer circumference of the mold die is released to the slip groove formed in the sub ring. Therefore, the sub-ring is more effective in absorbing the stress of the die die, the product is molded in a quick time, as well as the product is formed, and the part or all of the molding space is not damaged when the product is ejected.
