Abstract

음극선관 판넬 성형용 금형의 플런저 냉각시 플런저(50)의 중앙부와 모서리부의 냉각효과가 상이함으로 인한 냉각 밸런스 조절의 어려움을 방지할 수 있을 뿐만 아니라 외부 플런저(54) 중앙부의 과열로 인한 부식과 이로 인한 금형의 수명저하를 방지하기 위하여 플런저(50)의 코너부와 중앙부에 각각의 냉각라인(1a, 1b)을 설치하여 중앙부와 외곽부가 각각 냉각되도록 함으로써 플런저(50)의 중앙부와 코너부에서의 냉각효율을 균일하게 함과 아울러 플런저(50)중앙부의 부식을 방지할 수 있게 된다.When cooling the plunger of the mold for forming the cathode ray tube panel, it is possible not only to prevent the difficulty of adjusting the cooling balance due to the difference in the cooling effect of the center portion and the corner portion of the plunger 50, but also to the corrosion caused by overheating of the center portion of the outer plunger 54. In order to prevent the deterioration of the life of the mold due to the installation of the respective cooling lines (1a, 1b) in the corners and the central portion of the plunger 50 so that the central portion and the outer portion are respectively cooled in the center portion and corner portion of the plunger 50 The cooling efficiency can be made uniform and the corrosion of the central portion of the plunger 50 can be prevented.
