Abstract

Формата намира приложение в пластмасовата промишленост. Конструкцията й осигурява задържане на използваната листова заготовка по време на впръскване на отливания състав, което обуславя повишена надеждност на процеса и високо качество на изработваните изделия. Формата се състои от позитивна (1) и негативна (2) полуформа, като в негативната (2) е монтирана леякова втулка (3), оформена с наставъчна част (7). Тази наставъчна част (7) е оразмерена така, че при затворено положение на двете полуформи (1 и 2) да изпъкне през отвора за впръскване на формовъчна маса (5) на листовата заготовка (4). Позитивната полуформа (1) има поне един отвор (8), свързан с тръбопровод за вакуум (9). Отворът (8) е оформен като процеп между корпуса на клапан (10) и неговото гнездо (11). Корпусът на клапана (10) е с възможност за гъвкаво еластично движение при отваряне и затваряне на полуформите (1 и 2). 6 претенции, 2 фигури
