Abstract

Изобретение относитс к литейному производству, в частности к устройствам дл получени безопочных литейных форм способом вакуумной формовки. Целью изобретени вл етс упрощение конструкции, улучшение качества форм и снижение пыле- выделени в атмосферу цеха. Устройство загрузки 4 формовочного материала расположено на предпоследней по ходу модельных плит 16 и 17 технологической позиции верхнего этажа формовочного автомата, а подъемник вибростола 11 установлен из позиции прот жки моделей 5. Кроме того, формовочный автомат снабжен наполнительной рамкой, подвижно закрепленной на горловине бункера устройства загрузки 4 с возможностью взаимодействи с моделью 18 и эластичной диафрагмой, закрепленной по периметру горловины. 1 з.п. ф-лы, 2 ил.The invention relates to a foundry, in particular, to devices for the production of flaskless molds by vacuum molding. The aim of the invention is to simplify the design, improve the quality of the molds and reduce dust emission into the atmosphere of the workshop. The loading device 4 of the molding material is located on the penultimate along the model plates 16 and 17 of the technological position of the upper floor of the molding machine, and the lift of the vibrating table 11 is installed from the drawing position of the models 5. In addition, the molding machine is equipped with a filling frame movably mounted on the hopper of the loading device hopper 4 with the ability to interact with the model 18 and an elastic diaphragm fixed around the perimeter of the neck. 1 hp f-ly, 2 ill.
