Description
Claims (3)
- 열가소성 플라스틱으로 이루어지는 시트형상의 표피를 가열하여 연화(軟化)시킨 상태로 주성형면(主成形面)과 종성형면(從成形面)으로 영역이 분할된 입체 성형면을 향하여 가압함으로써 그 성형면을 따라 표피성형하는 성형틀에 있어서,상기 성형면의 측면 2개가 교차하는 교차선의 정상부로부터 주성형면과 종성형면에 걸침과 아울러 상기 정상부로부터 이반(離反)하는 방향으로 연장하는 능선(稜線)을 지니는 유도판(誘導板)을 돌출하여 형성하고,상기 능선의 정상부 근처를 일단 종성형면을 향하여 인입한 후에 주성형면을 향하여 돌출되는 파형(波形)의 유도부를 형성하고,그 유도부에 의하여 가압시에 표피 일부를 유도하여 상기 주성형면 측 표피의 틈을 없게 하는 것을 특징으로 하는 성형틀.
- 제1항에 있어서,상기 유도판은 얇은 판상으로 함과 아울러 상기 유도판의 기초부를 따라 흡인수단(吸引手段)을 형성하는 것을 특징으로 하는 성형틀.
- 청구항1의 성형틀을 사용하는 성형방법으로서,상기 유도판 능선의 정상부 근처를 일단 종성형면을 향하여 인입한 후에 주성형면을 향하여 돌출한 파형의 유도판을 따라 가압하고, 표피의 일부를 유도하여 상기 주성형면측 표피의 틈을 없게 하면서 상기 유도판 기초부에 형성된 상기 흡인수단으로 흡인하여 상기 능선의 정상부 근처의 성형면에서 겹쳐 융착되도록 표피성형하는 것을 특징으로 하는 성형방법.
