Description
Изобретение относитс к переработке полимерных материалов и может быть использовано дл изготовлени методом лить под давлением из пластмасс полых длинномерных изделий, например тазов дл укладки ленты, патронов, катушек и т. д.The invention relates to the processing of polymeric materials and can be used to make hollow, long articles, such as cans for laying tapes, cartridges, coils, etc., by injection molding plastics.
Цель изобретени - расширение технологических возможностей формы за счет увеличени длины хода сталкивани изделий.The purpose of the invention is to expand the technological capabilities of the form by increasing the stroke length of the collision of products.
На фиг. 1 показана верхн часть литьевой формы в сомкнутом виде с рычажным механизмом сталкивани изделий с оформ- л юш,его знака, вертикальный разрез по оси симметрии; на фиг. 2 - то же, вертикальный разрез по плоскости смыкани литьевой формы; на фиг. 3 и 4 - упрощенна схема формы с рычажным механизмом в момент раскрыти и полного сталкивани издели .FIG. Figure 1 shows the upper part of the mold in a closed form with a lever mechanism for pushing products from the design of its shape, its sign, a vertical section along the axis of symmetry; in fig. 2 - the same, vertical section along the plane of the closure of the mold; in fig. 3 and 4 is a simplified diagram of the form with a lever mechanism at the time of opening and full collision of the product.
Литьева форма содержит подвижную 1 и неподвижную 2 полуформы, рычажный механизм , включаюш,ий траверсу 3, св занную т гами 4 со сталкивающей планкой 5, щарнирно св занные между собой и с полуформами длинные рычаги 6 и щарнирно св занные с ними и через планку 7 со знаками 8 короткие рычаги 9. Механизм имеет дополнительные верхние 10 и нижние 11 шарнирно св занные рычаги, причем нижние рычаги 11 жестко св заны с длинными рычагами, а верхние рычаги 10 - щарнирно с траверсой 3.The mold comprises a movable 1 and a fixed 2 half-molds, a lever mechanism, including traverse 3, connected by means of 4 with a pushing bar 5, hingedly long levers 6 and hingedly connected with them and through the bar 7 with signs 8 are short levers 9. The mechanism has additional upper 10 and lower 11 pivotally connected levers, the lower levers 11 being rigidly tied with long levers, and the upper levers 10 being hinged with a traverse 3.
Пары длинных 6 и коротких 9 рычагов, длинных 6 и дополнительных верхних 10 и длинных 6 св заны в местах щарнирно- го соединени промежуточными планкамиPairs of long 6 and short 9 levers, long 6 and additional top 10 and long 6 are connected at the hinge joints by intermediate strips
12-14 соответственно. На планке 7 закреплена щтанга 15, дл которой в траверсе 3 выполнено отверстие. Такое конструктивное решение позвол ет увеличить длину хода сталкивани изделий при сохранении в сравнении с известным техническим решением величины раскрыти формы.12-14, respectively. On the strap 7, the shtanga 15 is fixed, for which a hole is made in the traverse 3. Such a constructive solution allows an increase in the stroke length of the collision of the products while retaining, in comparison with the known technical solution, the value of the shape opening.
Форма работает следующим образом. После впрыска полимера и технологической выдержки производитс раскрытие формы, при этом траверса 3 перемещаетс вниз, а планка 7 удерживаетс на месте . Св занна с траверсой 3 т гами сталкивающа планка 5 также опускаетс вниз, сталкива издели со знаков 8. Далее форма смыкаетс и цикл повтор етс .The form works as follows. After the injection of the polymer and the processing time, the mold is opened, while the yoke 3 is moved down and the bar 7 is held in place. The collision bar 5, which is connected to the crossbeam 3 g, is also lowered downwards, pushing the product from the signs 8. Next, the shape closes and the cycle repeats.
