Изобретение относитс к области переработки пластмасс и может быть использовано дл изготовлени длинномерных полых изделий, например футл ров дл медицинских термометров. The invention relates to the field of plastics processing and can be used for the manufacture of long hollow articles, such as cases for medical thermometers.
Известна литьева форма дл изготовлени изделий с поднутрением, содержаща оформл ющий поднутрение зиак и механизм его перемещени , выполненный в виде ишбера 1.A well-known injection mold for the manufacture of articles with undercuts, containing an embossed diacter and its movement mechanism, made in the form of an isber 1.
В известной форме нельз получать длинномерные.полые издели , так как ход знака ограничен и не может быть больше величины, равной третьей части хода раскрыти формы.It is not possible to get lengthy hollow products in a known form, since the sign travel is limited and cannot be greater than a value equal to the third part of the shape opening stroke.
Известна также литьева форма дл изготовлени длинномерных полых изделий из полимеров, содержаща подвижную и неподвижную полуформы, сталкивакичую втулку, размещенную на знаке , и рычсикный механизм, выполненный ,иэ двух пар рычагов, одни концы которых первой пары шарнирно соединены с полуформами, и другие концы рычагов этой пары шарнирно соединены, между собой и со сталкивающей втулкой чере т ги, а одни концы рычагов второй пары шарнирно соединены между собой 2A casting mold for the manufacture of long hollow polymer products is also known, comprising movable and stationary half-molds, a push-in sleeve placed on the sign, and a lever mechanism, made of two pairs of levers, one ends of which the first pair is hinged to the half-molds, and other ends of the levers of this pair are pivotally connected, with each other and with the colliding sleeve of the tie rod, and one ends of the levers of the second pair are pivotally interconnected 2
В изйёстной литьевой форме величина максимального хода сталкивающей втулки относительно, знака составл ет . меньше половины величины хода раскрыти формы, что снижает надежность удалени изделий из формы.In a smooth injection mold, the magnitude of the maximum stroke of the colliding sleeve is relative, the sign is. less than half the stroke of the mold, which reduces the reliability of removing articles from the mold.
Цель Изобретени - повышение надежности съема со знака изделий с длиной отверсти или поднутрени , превышающей половину хода раскрыти формы .The purpose of the invention is to improve the reliability of removal of the mark of products with a hole length or undercut longer than half the stroke of the opening form.
Поставленна цель достигаетс тем, что предлагаема форма снабжена гой, выполненной в виде Г-образного злемента, один конец которого жестко св зан со знаком, а другой конец шарнирно соединен с шарнирно соединенньв и концами второй пары рычагов, дру20 гие концы которых шарнирно закреплены на полуформах.The goal is achieved by the fact that the proposed form is equipped with a goy made in the form of an L-shaped element, one end of which is rigidly connected to the sign, and the other end is pivotally connected to the pivotally connected and ends of the second pair of levers, the other ends of which are pivotally fixed on the half-shapes .
На фиг. 1 дан общий вид формы в сомкнутом положении; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 - об25 Щий вид формы в раскрытом положении; на фиг. 4 - сечение Б-Б на фиг. 3.FIG. 1 given a general view of the form in a closed position; in fig. 2 is a section A-A in FIG. one; in fig. 3 - general view of the form in the open position; in fig. 4 is a section BB in FIG. 3
Форма содержит подвижную 1 и неподвижную 2 полуформы, рычажный механизм , выполненный из двух пар рыча30 грв 3, сталкивающую втулку 4, закрепThe form contains a movable 1 and a fixed 2 half-form, a lever mechanism made of two pairs of levers 30 grooves 3, pushing the sleeve 4, secured
