Abstract

본 발명은 온수순환펌프용 펌하우징의 성형방법에 관한 것으로 코어의 제작 및 코어제거공정이 없이 성형됨과 언더컷이 없어지므로 대량생산이 가능하게 되고 성형공정이 단순화하도록 하여 결국적으로 제조원가가 절감되도록 하며, 1차 성형물(10)이 2차 금형(30)에서 2차 성형공정시 주입되는 용탕의 압력에 의해 흔들리는 것과 용탕이 1차 성형물(10)의 내부로 유입이 되는 것을 방지시켜 제품의 품질이 향상되도록 하므로 결국적으로 사용자의 신뢰성을 향상시키도록 하는 온수순환펌프용 펌프하우징의 성형방법과 그 성형물에 관한 것이다.

Claims (3)

  1. 펌프하우징(20')의 성형방법에 있어서, 펌프하우징(20')의 각각 반을 사출할 수 있는 1차 금형을 성형하는 1차 금형제작공정과, 펌프하우징(20')의 외형을 형성한 2차 금형(30)을 제작하는 2차 금형제작공정과, 상기 1차 금형에 의해 코어의 역할을 하는 1차 성형물(10)을 사출하는 1차 성형공정과, 상기 각각 반으로 사출된 1차 성형물(10)을 2차 금형(30)에 삽입 설치하여 2차 성형물(20)을 성형하는 2차 성형공정으로 이루어짐을 특징으로 하는 온수순환펌프용 펌프하우징의 성형방법.
  2. 2차 성형공정시 2차금형에 설치된 1차 성형물(10)이 유동되는 것이 방지되도록 1차 성형물(10)의 외형에 돌출돌기(11)를 갖도록 형성되고 1차 성형물(10)의 내부로 용탕의 유입이 방지되도록 1차 성형물(10)의 각각 반을 조합하는 접합면의 일측부에는 가이드돌기(12)가 형성되고 타측부에는 가이드홈(13)이 형성됨을 특징으로 하는 온수 순환펌프용 펌프하우징의 성형물.
  3. 제2항에 있어서, 상기 1차 금형에 2차 성형공정시 용탕과 상기 1차 성형물(10)과의 용착을 원활히 할 수 있도록 1차 성형물(10)의 외형에 요홈(14)을 갖도록 형성됨을 특징으로 하는 온수순환펌프용 펌프하우징의 성형물.
