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 фигуриThe mold is used in the plastics industry. Its construction ensures retention of the used sheet blank during injection of the cast composition, which determines increased reliability of the process and high quality of the manufactured products. The mold consists of a positive (1) and a negative (2) half-mold, and in the negative (2) a funnel sleeve (3) formed with an extension part (7) is installed. This extension part (7) is dimensioned so that in the closed position of the two half-forms (1 and 2) it protrudes through the injection hole of the molding mass (5) of the sheet blank (4). The positive half-form (1) has at least one opening (8) connected to a vacuum line (9). The opening (8) is formed as a slot between the valve body (10) and its seat (11). The valve body (10) is capable of flexible elastic movement when opening and closing the half-forms (1 and 2). 6 claims, 2 figures
