发明名称 Aparelho e processo para moldagem por compressão de artigos plásticos
摘要 A method for compression molding of plastic articles (F), comprises molding a dose (D) of plastic material in a molding unit (3, 4) between an upper punch (3) and a lower mold (4) comprising a cavity (5), the upper punch (3) and the lower mold (4) being mutually aligned and movable between a spaced position and a close position, feeding said dose (D) by using feeding means (12, 13, 14) for removing said dose (D) from an extruder (14) and delivering the removed dose (D) to supporting means (18, 19, 20, 21, 26, 27) temporarily supporting said dose (D) when said lower mold (4) is still spaced away from said punch (3), and further comprising actuating said supporting means (18, 19, 20, 21, 26, 27) by using actuating means (32; 41; 42) so as to release said dose (D) into said cavity (5) before said punch (3) and said lower mold (4) start the compression step, said actuating comprising moving said cavity (5) towards said punch (3) such that said dose (D) is separated from said supporting means (18, 19, 20, 21, 26, 27).
