본 고안은 전선에 합성수지를 피복하는 전선피복용 틀에 관한 것이다.The present invention relates to a wire coating frame for coating a synthetic resin on the wire.
종래에는 전선에 합성수지를 피복함에 있어서 일정 두께의 절연물질을 한번 성형틀을 통과하여 피복함으로써 피복된 절연체에 기포가 발생하기 때문에 절연이 극히 불량하여 전선의 장기적 내구성이 약하다는 단점이 노출됨과 더불어 불량품 처리에 따른 막대한 원자재 및 인건비가 투입이 불가피하여 비경제적이었다.Conventionally, in coating a synthetic resin on an electric wire, since an insulating material having a predetermined thickness is coated through a molding mold to generate bubbles, the insulation is extremely poor and the long-term durability of the electric wire is weak. The huge raw material and labor costs associated with the treatment were uneconomical due to the inevitable input.
본 고안은 이러한 점을 감안하여 고안한 것으로서 성형틀 내에서 2차 피복이 이루어지도록 하여 줌으로써 피복된 절연체에 기포가 발생하는 일이 없이 불량품이 발생하는 것을 미연에 방지할 수 있도록 한 것이다.The present invention was devised in view of this point, and the secondary coating is made in the mold to prevent the occurrence of defective products without bubbles in the coated insulator.
이와 같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.When the present invention as described by the accompanying drawings as follows.
성형틀(1)내에 액상의 절연체가 투입되는 투입구(2) 및 전선 삽입구(3)와 배출구(4)가 형성된 공지의 것에 있어서 투입구(2)내에 격벽(5)을 형성하되 격벽(5)의 선단부의 내경이 배출구(4)의 직경보다 작게 형성하여 1차 피복부(6)와 2차 피복부(7)가 형성되도록 하여서된 것이다.In the well-known thing in which the insulator 2 into which the liquid insulator is put into the molding die 1 and the electric wire insertion hole 3 and the discharge hole 4 are formed, the partition wall 5 is formed in the inlet port 2, but the The inner diameter of the tip portion is smaller than the diameter of the discharge port 4 so that the primary cover portion 6 and the secondary cover portion 7 are formed.
도면중(8)은 절연채 9는 전선이다.In the figure (8), the insulator 9 is an electric wire.
이와 같이 된 본 고안의 효과를 설명하면 다음과 같다.When explaining the effect of the present invention as described above is as follows.
전선(9)에 절연체(8)를 피복코저 할때는 전선(9)을 전선 삽입구(3)내에 밀어 넣으면서 성형틀(1)의 투입구(2)내로 액상의 절연체를 투입하면 액상의 절연체는 격벽(5)에 의하여 1차 피복부(6)와 2차 피복부(7)로 나누어져서 성형틀(1)내로 밀려 들어간다.When covering the insulator 8 on the wire 9, the liquid insulator is inserted into the inlet 2 of the forming mold 1 while pushing the wire 9 into the wire insertion hole 3. ), It is divided into the primary coating portion 6 and the secondary coating portion 7 and pushed into the mold 1.
이와 같이 투입된 절연체가 성형틀(1)내를 통과하는 전선(9)에 절연체가 피복이 되는 것이다.The insulator is coated on the wire 9 through which the insulator injected in this way passes through the mold 1.
이와 같이 전선(9)에 절연체(8)가 피복되는 것을 살펴보면 액상의 절연체가 투입구(2)를 통하여 1차 피복부(6)내에서 전선에 얇게 일차 피복이 되고 다시 2차 피복부(7)에 의하여 재차 피복이 되는 것으로서 종래와 같이 일정 두께를 한꺼번에 피복하지 않고 하나의 성형틀내에서 얇게 2회에 걸쳐 반복하여 피복이 되기 때문에 전선에 피복된 절연체에 기포가 발생하는 것을 방지하여 절연효과를 높일 수 있게한 유용한 고안이다.As described above, when the insulator 8 is coated on the wire 9, the liquid insulator is thinly coated on the wire in the primary cover 6 through the inlet 2, and then the secondary cover 7 is again covered. It is covered again by the coating, and the coating is repeatedly made twice in one molding frame without covering a certain thickness at the same time as in the prior art, thereby preventing the occurrence of air bubbles in the insulator coated on the electric wire and increasing the insulation effect. It is a useful design that makes it possible.
