Abstract

본 발명은 봉입 성형용의 모울딩 프레스 장치의 금형의 관한 것으로, 구체적으로는 캠 구동방식으로 봉입성형(ENCAPSULATION)을 위한 수지를 압송시키면서 낭비를 최소화시키도록 등거리에 다수의 포트와 플린저를 갖추고, 기존의 모울딩 프레스 장치에 적용이 가능하게 설계된 금형에 관한 것이다.The present invention relates to a mold of a molding press apparatus for encapsulation. Specifically, a plurality of ports and plungers are equidistantly equilibrated to minimize waste while feeding resin for encapsulation by a cam driving method. The present invention relates to a mold designed to be applicable to a conventional molding press apparatus.

본 발명은 봉입 성형용 모울딩 프레스 장치의 상ㆍ하부 금형에 있어서, 상ㆍ하형 플레이트 사이의 상ㆍ하 체이스상에 상ㆍ하 캐비티블럭이 설치되고, 이 상ㆍ하 캐비티블럭내에 리드프레임이 놓여져서, 상ㆍ하 캐비티블럭에 장착되는 런너블럭의 런너를 따라 용융된 수지가 상기 리드프레임을 봉입시키도록 압송되도록 하되, 하부금형상에 캠지지봉을 설치하여 캠축에서 시이소오 운동이 되도록 캠을 설치하고, 이 캠의 일측을 눌러주도록 압력로드가 하부금형을 관통하여 수직으로 설치되며, 캠의 타측은 쿠션블럭상의 플런저와 일체로 결합된 하이동판을 하부에 떠받치듯 접촉되고, 상기 하이동판은 랙과 피니언으로 구성되는 기어로 수평 승강되게 결합된 채 스프링블럭상에 복원용 스프링으로 탄지되는 구성을 갖는 것이다.The upper and lower cavity blocks are provided on the upper and lower chases between the upper and lower mold plates, and the lead frame is placed in the upper and lower cavity blocks in the upper and lower molds of the molding press apparatus for sealing molding. The molten resin is pushed along the runner of the runner block mounted on the upper and lower cavity blocks so as to enclose the lead frame. The pressure rod is installed vertically through the lower mold so as to press one side of the cam, and the other side of the cam contacts the high copper plate integrally coupled with the plunger on the cushion block as if it is holding the lower copper plate. It is to have a configuration that is supported as a restoring spring on the spring block while being coupled horizontally elevated by the gear consisting of and pinion.
