Claims (3)
- 사출성형방법에 있어서, 제한통로의 다른 단부에서 측방향으로 돌출한 배출관(53)을 가지는 제한통로(48, 53)의 한단부(51)내로 미세한 사출재료를 주입하는 단계와, 사출노즐유니트(19)내로 배출시키기 위한 배출관(53)을 향하여 제한통로(48, 53)에서 사출재료를 연속적으로 전진시키는 단계와, 상기 통로를 통과하는 동안에 사출재료를 균일하게 가열부재(76)로 가열시키는 단계와, 주형(18)내로 사출재료를 사출시키는 사출노즐 유니트(19)로 배출관(53)을 이동시키기 위하여 사출노즐 유니트(19)에 관하여 일방향으로 제한통로(48, 53)를 이동시키는 단계와, 연속적으로 전진하는 사출재료가 배출관(53)에서 사출노즐 유니트(19)내로 배출됨에 따라 사출노즐 유니트에 관하여 역방향으로 소정거리만큼 제한통로를 이동시키는 단계를 구비하는 것을 특징으로 하는 사출성형방법.
- 제1항에 있어서, 주형(18)내로 재료를 사출하는 동안에 제한통로(48)에서 재료가 배출관(53)을 향하여 이동하지 못하게 차단하는 단계를 구비하는 것을 특징으로 하는 사출성형방법.
- 제1항에 있어서, 주형(18)내로 사출시키기 위한 사출노즐 유니트(19)내로 배출되는 사출재료의 양을 변화시키기 위하여 사출노즐 유니트(19)에 관하여 역방향으로 제한통로(48, 53)의 이등을 변화시키는 단계를 구비하는 것을 특징으로 하는 사출성형방법.
