Abstract

Предлагаемые способ и устройство касаются получения на основа шликера или густой тестообразной массы сырых заготовок 10 путем отверждения этой массы после нагнетания ее под давлением в литейную форму, имеющую температуру ниже 0°С. Литейная форма 1, 2 и подвижные части 6 силового цилиндра 7, который обеспечивает ее закрытие, размещаются в герметичном кожухе 8. Распределительное устройство 13 обеспечивает подачу во внутреннюю полость кожуха сухого газа с точкой росы ниже рабочей температуры данной литейной формы через отверстия 14. Лоток или короб 9 подводит сырую заготовку 10 через выходное отверстие 11 к приемнику 17, находящемуся за пределами упомянутого кожуха. Применяется при изготовлении спекаемых металлических или керамических деталей высокой плотности и с высокими механическими характеристиками.
