Abstract
Способ физико-технического упрочнения облицовочных жидкостекольных самотвердеющих смесей в оснастке при изготовлении комбинированных форм и стержней, включающий предварительный подогрев песка до температуры 18-25°С при приготовлении облицовочной жидкостекольной формовочной смеси, подачу ее в оснастку и формирование облицовочного слоя с помощью контрмодельной решетки, отсос воздуха из оснастки, последующая продувка горячим воздухом с температурой 18-40°С с одновременным отсосом воздуха со стороны противоположной подаче горячего воздуха, последующую продувку облицовочной жидкостекольной формовочной смеси углекислым газом с одновременным отсосом газовоздушной смеси со стороны противоположной подаче углекислого газа и воздуха, и после формирования жидкостекольного облицовочного слоя в оснастку подают наполнительную смесь, которую уплотняют воздушным потоком, а затем прессуют, например, многоплунжерной головкой, со стороны контрлада оснастки. слоя из ЖСС и его отверждения подачу в оснастку наполнительной смеси с уплотнением ее прессованием со стороны контрлада оснастки. A method of physicotechnical hardening of self-hardening facing glass mixtures in equipment during the manufacture of combined molds and cores, including pre-heating sand to a temperature of 18-25 ° C during preparation of the facing liquid-glass molding mixture, supplying it to equipment and forming the facing layer using a counter-model grate, suction air from a snap, subsequent purging with hot air with a temperature of 18-40 ° С with simultaneous suction of air from the opposite side of the hot air supply ha, the subsequent blowing of the facing liquid glass molding mixture with carbon dioxide with the simultaneous suction of the air-gas mixture from the opposite side of the supply of carbon dioxide and air, and after the formation of the liquid glass facing layer, the filling mixture is fed into the tooling, which is sealed with an air stream and then pressed, for example, with a plunger head, from the back of the snap. a layer of LSS and its curing, the filing of the filler mixture into the equipment with compaction by pressing from the side of the tooling counter.
