Description
Изобретение относитс к литейному производству, в частности к производству отливок методом вакуумно-пленоч- ной формовки в крупногабаритных формах.The invention relates to foundry, in particular, to the production of castings by vacuum-film forming in large-sized forms.
Цель изобретени - упрощение процесса .The purpose of the invention is to simplify the process.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
Сущность способа заключаетс в следующем.The essence of the method is as follows.
Залитую и охлажденную литейную форму 1 устанавливают на выбивную решетку 2 и накрывают крьшкой 3, уплотненной по периметру опоки 4. Решетка может быть смонтирована непосредственно на позиции выбивки или служить в качестве транспортного средства. Поскольку опоки дл крупногабаритных форм вьшолнены с крестовинами , свободное удаление пленки после сн ти вакуума невозможно.Flooded and cooled casting mold 1 is installed on the embossing grill 2 and covered with a cover 3, compacted around the perimeter of the flask 4. The grille can be mounted directly on the knockout position or serve as a vehicle. Since the flasks for large-sized forms are made with cross-pieces, free removal of the film after the vacuum is removed is impossible.
После установки форьы 1 на решетке 2 нижнюю облицовочную пленку 5 вAfter installing fory 1 on the grille 2, the lower facing film 5 in

местах просветов решетки 2 разрушают рассекател ми 6, которые могут быть выполнены, например, в виде поворотных ножей или нагревательных элементов, подключенных к источнику тока, и встроены непосредственно в решетку или установлены отдельно от нее.In places of the gaps, the grids 2 are destroyed by the splitters 6, which can be made, for example, in the form of rotary knives or heating elements connected to the current source, and embedded directly in the grid or mounted separately from it.
Как только целостность облицовоч- ной нижней пленки 5 рассекател ми 6 нарушена, песчана смесь дл пылевы- делени через отверсти в нижней пленке 5 и просветы решетки 2 ссыпаетс в приемньй бункер 7, после чего сни- мают крышку 3 и верхнюю опоку 4, извлекают отливку 8, снимают нижнюю опорку 9 и удал ют нижнюю пленку 5. IAs soon as the integrity of the cladding bottom film 5 is broken by the splitters 6, the sandy mixture for dust emission through the holes in the lower film 5 and the gaps of the grille 2 is poured into the receiving bin 7, then the cover 3 and the upper flask 4 are removed, the casting is removed 8, remove the lower support 9 and remove the lower film 5. I
Способ выбивки литейных форм поз- вол ет отказатьс от дополнительного вакуумного насоса, специального устройства дл сн ти нижней пленки, пы- лезап{итных устройств. Процесс выбивки упрощаетс .The method of knocking out casting molds makes it possible to refuse an additional vacuum pump, a special device for removing the lower film, and dusty devices. The knockout process is simplified.
