Description
Изобретение относится к области переработки полимеров, в частности к оснастке для изготовления методом компрессионного прессования крупногабаритных изделий из волокнистых · пресс-материалов.The invention relates to the field of polymer processing, in particular to equipment for the manufacture by compression pressing of large-sized products from fibrous · press materials.
Известна пресс-форма для изготовления полимерных изделий методом компрессионного прессования, содержащая пуансоны и матрицу, включающую стационарную загрузочную камеру [1].A known mold for the manufacture of polymeric products by compression molding, containing punches and a matrix including a stationary loading chamber [1].
Недостатком известных форм является то, что при изготовлении ‘высоких крупногабаритных изделий с небольшой 1 площадью проекции они должны иметь большую высоту загрузочной камеры, . а это значительно увеличивает высоту пресс-формы. При прессовании крупногабаритных изделий, например вы- 2 сотой 250-300 мм, открытая высота пресса должна быть не менее двух метров. Промышленностью выпускаются прессы с открытой высотой 2 м только усилием 1000 тс и более. Для прес- 2 сования деталей очень часто необходимо усилие прессования 250-500 тс.A disadvantage of the known forms is that in the manufacture of ‘high large-sized products with a small 1 projection area, they must have a large loading chamber height,. and this greatly increases the height of the mold. When pressing large products, for example, a height of 250-300 mm, the open height of the press should be at least two meters. The industry produces presses with an open height of 2 m only with a force of 1000 tf or more. For pressing parts 2 very often a pressing force of 250-500 tf is needed.
Цель изобретения — расширение технологических возможностей оборудования. 3The purpose of the invention is the expansion of technological capabilities of equipment. 3
Поставленная цель достигается тем, что пресс-форма для изготовления полимерных изделий методом компрессионного прессования, содержащая пуансон и матрицу, включающую стационарную загрузочную камеру,-снабжена съемной загрузочной камерой, установленной на матрице соосно стационарной камере и выполненной из разъемных по высоте частей.This goal is achieved in that the mold for the manufacture of polymer products by compression molding, containing a punch and a matrix including a stationary loading chamber, is equipped with a removable loading chamber mounted on the matrix coaxially with the stationary chamber and made of parts that are detachable in height.
На фиг.1 изображен общий вид прессформы; на фиг.2 — сечение А-А фиг.1.Figure 1 shows a General view of the mold; figure 2 is a section aa of figure 1.
Пресс-форма содержит пуансон 1 с пуансонодержателем, матрицу 2, включающую (стационарную загрузочную камеру 3, где происходит основное уплотнение материала при больших давлениях прессования. Съемную разъемную загрузочную камеру 4, где происходит опрессовка материала при незначительных давлениях, и толкатель 5.The mold contains a punch 1 with a punch holder, a matrix 2 including (stationary loading chamber 3, where the main material is compressed at high pressing pressures. A removable split loading chamber 4, where the material is pressed at low pressures, and a pusher 5.
Пресс-форма работает следующим образом.The mold works as follows.
Нижний пакет пресс-формы — матрицу 2 с загрузочной камерой 4 устанавливают на стол пресса. Верхний пакет пресс-формы — пуансон 1 крепят к подвижной траверсе пресса. В исходном состоянии перед загрузкой пресс-ма730575 териала съемная разборная загрузочная камера 4 устанавливается на стационарную и закрепляется посредством буртиков, выполненных на кольцах разъемной камеры. Толкатель 5 находится в крайнем нижнем положении. Загрузку $ материала производят в оформляющую полость пресс-формы и съемную и стационарную загрузочные камеры. Материал опрессовывается пуансоном 1. После прохождения пуансоном нижней части . „ первого кольца загрузочной камеры 'υ ход пресса останавливают и кольцо разбирают и снимают. После прохождения пуансоном следующих колец их снимают. При заходе пуансона в стационарную загрузочную камеру все части 15 съемной загрузочной камеры снимаются и прессование производят известным образом. Распрессовку детали производят без съемной загрузочной камеры.The bottom package of the mold - the matrix 2 with the loading chamber 4 is installed on the table of the press. The upper package of the mold - the punch 1 is attached to the movable traverse of the press. In the initial state, before loading the press 730575, the removable collapsible loading chamber 4 is mounted on a stationary one and fixed by means of collars made on the rings of the split chamber. The pusher 5 is in its lowest position. The $ material is loaded into the forming cavity of the mold and the removable and stationary loading chambers. The material is crimped by punch 1. After the punch passes through the bottom. “The first ring of the loading chamber” υ the press stops and the ring is disassembled and removed. After the punch passes the following rings, they are removed. When the punch enters the stationary loading chamber, all parts 15 of the removable loading chamber are removed and pressing is carried out in a known manner. The parts are pressed out without a removable loading chamber.
Пример. Для изготовления крупногабаритных деталей высотой 250 мм методом компрессионного прессования необходима пресс-форма со стационарной загрузочной камерой, имеющая следующие характеристики:Example. For the manufacture of large parts with a height of 250 mm by compression pressing, a mold with a stationary loading chamber is required, having the following characteristics:
