Abstract

본 발명은 전기접속을 위한 잭등의 성형품을 제조하기 위한 방법에 관한 것으로서, 와이어상의 선재를 소정길이로 절단하여 다이내에 위치시키고 내측면에 요홈부가 형성된 다이내에 상기 성형품을 위치시키고 내측에 펀치를 작동시켜 컵 형상의 성형품을 형성시키고 공정과 내측면에 요홈부가 형성된 다이내 상기 성형품을 위치시키고 그 내측에 삽입되는 가이드 판에 형성된 턱부와 그 외측에 삽입 설치된 파이프 펀치의 선단사이에 수지체를 개재시켜 상기 파이프 펀치의 작동에 따라 압력을 받은 수지체가 상기 요홈부내로 압축되면서 주름부를 형성시키는 공정으로 이루어져 재료비를 절감하여 제조코스트를 다운시키고 제조가 간단하여 생산성을 향상시킬 수 있게 된다.The present invention relates to a method for manufacturing a molded article such as a jack for electrical connection, the wire is cut to a predetermined length and placed in the die, the molded article is placed in the die formed with a recess on the inner side and the punch is operated inside. To form a cup-shaped molded article, and place the molded article in the die where the groove is formed in the process and the inner side, and interpose the resin body between the jaw portion formed in the guide plate inserted into the inner side and the end of the pipe punch inserted into the outer side. The resin body under pressure according to the operation of the pipe punch is compressed into the recess to form a pleat, thereby reducing the material cost and reducing the manufacturing cost, thereby improving productivity.
