이 발명은 복수개의 인서트전극자를 인서트성형시켜서된 인서트전극몰드체의 제조방법에 관한 것이다.
제4도는 내연기관의 크랭크각의 검출에 사용되는 회전각도 검출장치를 구성하는 인서트전극몰드체의 평면도, 제5도는 그 이면도, 제6도는 제5도의 Ⅵ-Ⅵ선의 단면도, 제7도는 제4도의 인서트전극몰드체내에 내장된 인서트전극인데, 1,2,3,4,5는 각각 제1 내지 제5의 인서트전극자, 6은 수지, 7은 인서트전극몰드체의 이면에 복수개 형성된 구멍이다.
상기와 같이 구성된 인서트전극몰드체는, 복수개의 압핀을 사용하여 형내(型內)에 제1 내지 제5의 인서트전극자(1),(2),(3),(4),(5)를 각각 소정위치에 위치결정하고 그 후에 형내에 수지를 주입시켜 제조된다.
상기와 같이 구성된 종래의 인서트전극몰드체에 있어서는, 제1 내지 제5도의 인서트전극자(1),(2),(3),(4),(5)를 형내에 위치결정하기 위하여 사용된 압핀때문에 구멍(7)이 인서트전극몰드체의 이면에 복수개 형성되며 제1 내지 제5도의 인서트전극자(1),(2),(3),(4),(5)의 금속이 노출되어 있기 때문에 각 구멍(7)을 실리콘계 접착제로 봉지하는 작업을 하지 않으면 안되는 문제점이 있었다. 또 제1 내지 제5의 인서트전극자(1),(2),(3),(4),(5)를 형내의 소정위치에 각각 위치결정하기 위한 작업도 곤란하다는 문제점이 있었다.
이 발명은 이러한 문제점을 해소시키기 위해 발명된 것으로서, 인서트전극자의 금속노출이 방지되고 또 제조가 간단한 인서트전그몰드체의 제조방법을 얻은데 그 목적이 있다.
이 발명은 복수개의 인서트전극자가 일체화된 인서트적극체를 프리몰드(Premold)하고 그 다음, 인서트전극체를 절단하여 전기적으로 독립된 복수개의 인서트전극자로된 1차성형품으로 하고, 다음에 이 1차성형품을 인서트성형시킨 것이다.
이 발명에 있어서는, 프리몰드된 인서트전극체를 절단하여 복수개의 인서트전극체를 형성하므로 인서트전극자가 개개로 흩어지지 않는다. 또 단일체인 1차성형품이 인서트성형된다.
이 발명의 실시예를 도면에 의하여 설명한다. 제1도 내지 제3도는 이 발명의 한 실시예를 나타낸 것으로서, 제4도 및 제7도와 동일한 부분은 동일부호를 붙이고 그 설명은 생략한다. 인서트전극몰드체의 제조에 있어서는, 우선 복수개의 인서트전극자가 일체화된 인서트전극체(10)에 수지(11)를 프리몰드한다(제3도 참조). 그 다음, 인서트전극체(10)를 절단하여 전기적으로 독립된 복수개의 인서트전극자(12)로 된 1차성형품(13)을 형성한다(제2도 참조).
다음에 이 1차성형품(13)을 인서트성형시켜 인서트전극몰드체가 성형된다(제1도 참조).
상기와 같이 제조된 인서트전극몰드체에서는, 1차성형품(13)을 압핀을 사용하여 형내의 소정위치에 위치 결정한 상태에서 형내에 수지를 주입하게 되는데, 이때 압핀은 수지(11)와 접촉하게 되고 따라서 인서트전극몰드체에는 구멍(14)이 형성되지만, 인서트전극자(12)의 금속이 노출되지는 않는다. 또 형내에서는 단일체인 1차성형품(13)을 압핀을 사용하여 위치결정하면 되며 형내에서의 1차성형품(13)의 위치결정은 용이하게 할 수 있다.
이상에서 설명한 것과 같이 이 발명의 인세트전극몰드체에 의하면 복수개의 인서트전극자가 일체화된 인서트전극체를 프리몰드하고, 그후, 인서트전극체를 절단하여 전기적으로 독립된 복수개의 인서트전극자로된 1차성형품으로 하고, 다음에 이 1차성형품을 인서트성형함으로서 인서트전극몰드체에는 구멍이 형성되지만, 인서트전극자의 금속이 노출되지 않으므로 일부러 금속노출 방지대책을 세울 필요가 없다는 효과가 있다. 또 형내에서는 단일체인 1차성형품을 압핀을 사용하여 위치결정하면 되는데, 형내에서의 1차성형품의 위치 결정이 용이하여 자동화를 보다 간단하게 할 수 있는 효과가 있다.
