Description

외부에 산과 골이 나선상으로 형성된 플라스틱과용 압출다이
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (6)

  1. 이음매 없는 플라스틱관, 특히 산(rib)과 골(groove)이 교호로 형성된 환상 외표면과 평활한 내면을 지닌 관을 제조하는 장치의 압출다이에 있어서,
    소정 압력하에 열가소 성재료의 압출물을 받기 위해 측면개구를 갖춘 중앙공을 지닌 압출헤드.
    상기 헤드에 부착되고 그의 방출단에 상기 압출물의 방출을 위해 그 길이 방향으로 뻗어 있는 공급로를 제공하는 기다란 노즐,
    노즐과 맨드릴이 점차 감소하는 내부용적의 환상 압출구를 각각 한정하고 그를 통해 압출물이 계속하여 흘러나와 노즐안 및 맨드릴 둘레에 패리슨(parison)을 형성하며, 상기 노즐과 동축관계로 상기 구멍(bore)에 위치하고 방출단에 상기 압출물의 방출을 위해 그의 길이 방향으로 뻗어 있는 플라스틱 안내로를 제공하기 위해 노즐로부터 떨어져 있는 중공 맨드릴로 이루어지고,
    상기 방출단은 그의 모선이 상기 헤드의 길이 방향축과 45°이상의 각을 형성하는 동축원추부를 가지며, 상기 방출단에서의 맨드릴의 직경은 노즐의 직경보다 작지 않은 것을 특징으로 하는 압출다이.
  2. 제 1 항에 있어서, 상기 방출단은 맨드릴 내측에 채용된 전기적 히터를 갖는 것을 특징으로 하는 압출다이.
  3. 제 1 항에 있어서, 맨드릴 둘레에 등거리로 상기 노즐을 장착하고 반경방향으로 상기 헤드에 배치된 스크루우를 가지며, 노즐의 측면과 상호작용하여 상기 맨드릴에 대하여 노즐의 반경방향 조정을 가능케하는 중심조정수단을 포함하는 것을 특징으로 하는 압출다이.
  4. 제 1 항에 있어서, 맨드릴이 축방향으로 조정될 때 압출구의 크기를 변화시키는데 유효하고, 상기 맨드릴을 길이 방향으로 조정하기 위한 나사부 형성 조정부재를 포함하는 것을 특징으로 하는 압출다이.
  5. 제 4 항에 있어서, 상기 맨드릴과 헤드를 접속하여 회전하지 않고 맨드릴의 축방향운동만을 허용하도록 키이, 스플라인 등과 같은 결합수단을 포함하는 것을 특징으로 하는 압출다이.
  6. 이음매 없는 플라스틱관, 특히 산과 곧이 교호로 형성된 환상의 외표면과 평탄한 내면을 지닌 관을 제조하는 장치의 압출다이에 있어서,
    소정압력하에 열가소 성재료의 압출물을 받기 위해 측면개구를 갖춘 중앙공을 지닌 압출헤드.
    상기 헤드에 부착되고 그의 방출단에 상기 압출물의 방출을 위해 그 길이 방향으로 뻗어 있는 공급로를 제공하는 긴 노즐,
    노즐과 맨드릴이 점차 감소하는 내부용적의 환상 압출구를 각각 한정하고 그를 통해 압출물이 연속적으로 흘러나와 노즐안 및 맨드릴 둘레에 패리슨을 형성하며, 상기 방출단은 그 모선이 상기 헤드의 길이 방향축과 45°이상의 각을 형성하는 동축원추부를 가지고, 상기 단에서의 맨드릴의 직경은 노즐의 직경보다 작지 않으며, 상기 노즐과 동축관계로 상기 구멍에 위치되고 방출단에 상기 압축물의 방출을 위해 그의 길이 방향으로 뻗어 있는 플라스틱 안내로를 제공하기 위해 노즐로부터 떨어져 있는 중공맨드릴 및 맨드릴이 축방향으로 조정될 때 압출구의 크기를 변화시키는데 유효하도록 상기 맨드릴을 길이 방향으로 조정하는 나사부형성 조정부재로 이루어지는 것을 특징으로 하는 압출다이.
