본 고안의 밴드 성형금형에 관한 것으로서, 특히 브라운관의 방폭밴드를 성형하기 위한 금형에 관한 것이다.The present invention relates to a band molding mold of the present invention, and more particularly, to a mold for molding an explosion-proof band of a CRT.
텔레비젼이나 컴퓨터 모니타용 브라운관 패널 외주에는 밴드를 감아 체결하여 브라운관이 외부에서 충격을 받아도 쉽게 폭발하지 않도록 하고 있다. 이 방폭밴드는 브라운관에 체결되기 전에 미리 원하는 형상으로 즉 패널 외주의 윤곽과 일치하여 들뜨는 부분이 없도록 성형하는 바, 이를 위하여 종래에는 제 3 도에 도시된 바와 같이 하나의 고정된 기판금형(1)위에 두쪽으로 된 가동금형(2)(2)을 한 방향으로만 슬라이딩 가능하게 설치하여 가동금형(2)(2')을 한 방향으로만 슬라이등 가능하게 설치하여 가동금형(2)(2)이 서로 접근해 있는 상태에서 방폭밴드를 가동금형 외주에 위치시키고 제 4 도에서와 같이 가동금형(2)(2)사이에 쇄기(3)를 박아 누르면 가동금형이 좌우로 밀려나 방폭밴드에 신장력을 가하도록 하였다. 그러나 이와 같은 종래의 금형은 가동금형이 한 방향 즉 길이방향으로만 밀려나도록 되어 있어 방폭밴드에도 길이방향에 치중하여 신장력이 작용하는 경향이 있었다.A band is wound around the CRT panel for TV and computer monitors to prevent the CRT from exploding easily even when it is impacted from the outside. The explosion-proof band is molded into a desired shape in advance before being fastened to the CRT so that there is no lifting part in accordance with the outline of the outer periphery of the panel. For this purpose, one fixed substrate mold 1 is conventionally shown as shown in FIG. Movable molds (2) and (2) are installed in two directions so as to be slidable in only one direction, and movable molds (2) and (2 ') can be slidable in only one direction. When the explosion-proof band is positioned on the movable mold outer circumference in the state of approaching each other, and the wedge 3 is pushed between the movable molds (2) and (2) as shown in FIG. To be added. However, such a conventional mold is such that the movable mold is pushed out in only one direction, that is, in the longitudinal direction, so that the explosion force tends to be concentrated in the longitudinal direction.
즉 방폭밴드의 장변부에 집중응력이 작용하여 불균일한 변형을 초래하며 결국 방폭밴드의 전체적인 기계적 강도를 약화시키는 결과를 가져오게 하였다.In other words, concentrated stress acts on the long side of the explosion-proof band, resulting in non-uniform deformation, resulting in weakening of the overall mechanical strength of the explosion-proof band.
따라서 본 고안의 목적은 방폭밴드의 길이에 따라 균일한 응력이 작용하여 균일한 변형이 되도록 하여 보다 기계적 강도가 높은 방폭밴드를 성형할 수 있는 밴드 성형금형을 제공함에 있다.Accordingly, an object of the present invention is to provide a band forming mold capable of forming an explosion-proof band having a higher mechanical strength by applying a uniform stress along the length of the explosion-proof band to make a uniform deformation.
이 목적을 달성하기 위하여 본 고안은 고정된 기판금형과 이 기판 금형을 중심으로 슬라이딩될 수 있는 4개로 분할된 가동금형으로 이루어진 것을 특징으로 한다.In order to achieve this object, the present invention is characterized by consisting of a fixed substrate mold and a movable mold divided into four that can be slid around the substrate mold.
이하 도면에 예시된 한 바람직한 실시예를 따라 본 고안을 상세히 설명한다. 제 1 도에는 본 고안에 의한 밴드 성형금형의 평면도가, 제 2 도에는 밴드 성형금형의 작동원리를 설명하는 단면도가 도시되어 있는 바, 하나의 기판금형(10)위에 4개로 분할된 가동금형 (20)(20)(20)(20)이 슬라이딩 가능하게 설치되어 있다.Hereinafter, the present invention will be described in detail according to one preferred embodiment illustrated in the drawings. FIG. 1 is a plan view of the band forming mold according to the present invention, and FIG. 2 is a cross-sectional view illustrating the principle of operation of the band forming mold. The movable mold divided into four parts on one substrate mold 10 ( 20, 20, 20 and 20 are slidably installed.
이들 가동금형의 외곽선을 연결하면 그 윤곽이 방폭밴드의 형상과 유사하고 전체적인 외곽 윤곽으로 볼 때 장변과 단변을 각각 2등분하는 식으로 분할되어 있으며, 각 가동금형(20)(20)(20)(20)은 대각선 방향으로 슬라이딩 될 수 있도록 설치되어 있다. 즉 각 가동금형들의 중앙에는 대각선 방향으로 안내장공(21)이 형성되어 기판금형(10)위로 돌출된 돌기(11)에 상기 안내장공(21)이 끼워진 후 안내볼트(12)에 의하여 고정됨과 동시에 안내볼트(12)가 상기 안내장공(11)상단 외주연에 형성된 요입부(22)에 맞물려 가동금형의 대각선 방향만으로의 슬라이딩을 허용한다.When the outlines of the movable molds are connected, the outline is similar to the shape of the explosion-proof band, and the long side and the short side are divided into two parts in terms of the overall outline, and each movable mold 20, 20, and 20 is divided. 20 is provided so that it may slide in a diagonal direction. That is, the guide hole 21 is formed in the center of each of the movable molds in a diagonal direction, and the guide hole 21 is inserted into the projection 11 protruding onto the substrate mold 10, and then fixed by the guide bolt 12. The guide bolt 12 is engaged with the concave indentation portion 22 formed at the outer periphery of the upper end of the guide hole 11 to allow sliding of the movable mold only in the diagonal direction.
한편 각 가동금형들의 중앙 코너를 일정크기로 절제하여 경사면(23)을 형성하여 각 경사면(23)들이 형성하는 공간부(25)에 쇄기(30)가 박혀 들어갈 수 있도록 한다.Meanwhile, the center corners of the movable molds are cut to a certain size to form the inclined surface 23 so that the wedges 30 may be embedded in the space 25 formed by the inclined surfaces 23.
이와같이 구성된 본 고안의 가동금형(20)(20)(20)(20)의 외곽선을 따라 성형할 방폭밴드(미도시)를 위치시키고 쇄기(30)를 상기 공간부(25)에 박아 넣으면 가동금형(20)(20)(20)(20)들이 외곽으로 밀려나 방폭밴드에 신장력을 가하여 원하는 형상으로 성형시킨다.Positioning the explosion-proof band (not shown) to be molded along the outline of the movable mold 20, 20, 20, 20 of the present invention configured as described above, and put the wedge 30 in the space 25, the movable mold (20) (20) (20) (20) are pushed outwards to apply an extension force to the explosion-proof band to form a desired shape.
이때 가동금형에 의하여 방폭밴드에 힘이 집중적으로 가해지는 부위가 각 코너이기 때문에 방폭밴드의 각 장변, 단변에 골고루 힘이 전해진다. 따라서 종래와 같이 장변에만 변형이 과도하게 일어나는 폐단이 없어지고 방폭밴드의 전 길이에 걸쳐서 균일한 변형이 일어나 전체적인 기계적인 강도를 높여주고 사용시 브라운관의 외부 충격에 대한 안전도를 향상시키는 특징이 있다.At this time, since the corners are the corners where the force is applied to the explosion-proof band by the movable mold, the force is evenly distributed to each long side and short side of the explosion-proof band. Therefore, as in the prior art, only the long edges of the deformation are excessively eliminated, and uniform deformation occurs over the entire length of the explosion-proof band, thereby increasing the overall mechanical strength and improving the safety against the external impact of the CRT when used.
