Изобретение относитс к литейному производству, и может быть использовано при изготовлении форм (например , оболочковых форм, облицованных кокилей) и стержней из термотвердеющих смесей.The invention relates to foundry, and can be used in the manufacture of molds (e.g., shell molds, lined molds) and rods from heat-hardening mixtures.
Цель изобретени - сокращение продолжительности изготовлени формы (стержн ).The purpose of the invention is to reduce the duration of the manufacture of the form (rod).
Пример. В чугунном стержневом щике изготавливают из термотвердеющей смеси на основе 95% песка 1К016 и 5% св зующего ОФП-011Л стержни-диски диаметром 160 мм и толщиной 12 мм. Ящик нагревают до 530 К. Заполнение щика смесью производ т пескодувным способом. После заполнени щика с помощью вакуумного насо96106Example. In a cast iron core box, heat-hardening mixture is made of 95% sand 1Q016 and 5% binder OFP-011L core-discs with a diameter of 160 mm and a thickness of 12 mm from a heat-hardening mixture. The box is heated to 530 K. The box is filled with sandblasting. After filling the box with a vacuum pump
са РВН-20 осуществл ют и импульсный отсос газов от смеси в течение всего процесса формировани стержн . Разрежение составл ет 10 КПа, длительность импульсов 5 с, интервал времени между импульсами 10 с,Sa RVN-20 also carries out pulsed suction of gases from the mixture during the entire process of rod formation. The vacuum is 10 kPa, the pulse duration is 5 s, the time interval between pulses is 10 s,
Импульсньй режим отсоса обеспечивает удаление из парового пространства смеси газообразных продуктов / твердени св зующего, уменьшает доThe pulsed suction mode ensures the removal of a mixture of gaseous products / hardening binder from the vapor space, reduces to
минимума захолаживание смеси просасываемым через нее. воздухом из окружающей среды. Таким образом, организаци импульсного отсоса создает оптимальные услови дл отверждени смеси как в газовом, так и в тепловом отношени х.the minimum cooling of the mixture sucked through it. air from the environment. Thus, the organization of pulsed suction creates optimal conditions for curing the mixture in both gas and thermal ratios.
