Description

사출성형기의 자동 퍼어징 방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도는 본 발명의 자동 퍼어징 방법을 실시하는 노즐 밸브를 노즐부에 갖는 사출성형기의 구체예를 나타낸 개략 구성 설명도이다.

Claims (6)

  1. 노즐부의 용융수지의 흐름을 제어하는 노즐밸브를 장착한 사출성형기의 자동 퍼어징 방법에 따라, (a) 새로운 재료를 재료 호퍼로부터 스크류 실린더로 공급하고, (b) 기설정된 시간중이나 혹은 기설정된 스트로크로 스크류가 후퇴하기까지 노즐밸브를 폐쇄한 상태로 스크류를 회전시켜 수지를 가소화하며, (c) 얼마후 노즐밸브를 소정의 각도범위로 개방하고 용융수지를 퍼어지하는, 것을 특징으로 하는 사출성형기의 자동 퍼어징 방법.
  2. 제 1 항에 있어서, 기설정된 회수로 수지 가소화 및 퍼지가 수행되는 것을 특징으로 하는 사출성형기의 자동 퍼어징 방법.
  3. 제 2 항에 있어서, 각 회수의 퍼어지 시마다 퍼어지시의 노즐밸브 개방각도를 각각 설정된 개방각도로 변화시키는 것을 특징으로 하는 사출성형기의 자동 퍼이징 방법.
  4. 제 2 항에 있어서, 상기 기설정된 회수의 수지 가소화 및 퍼어지가 소정 시간 내에 반복하여 수행되는 것을 특징으로 하는 사출성형기의 자동퍼어징 방법.
  5. 제 1 항에 있어서, 스크류의 1회 퍼어지 동작중에 퍼어지의 상기 노즐 밸브 개방각도를 기설정된 다단계로 변화시키는 것을 특징으로 하는 사출성형기의 자동 퍼어징 방법.
  6. 제 1 항에 있어서, 페어지시의 상기 노즐 밸브 개방각도를 각 회수의 퍼어지시마다 기설정된 개방각도로 변화시킴과 함게, 스크류의 1회 퍼어지 동작중에서 기설정된 다단계로 변화시키는 것을 특징으로 하는 사출성형기의 자동 퍼어징 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
