Description
Известный процесс получени литейных форм н стержней без сушки осуществл етс при помощи химического твердени смеси на жидком стекле газообразной углекислотой. При этом уплотнение смеси в опоке или стержневом щике ироизводитс на встр хивающей или пескоду 5г ной машине, а продувка уплотненной смеси углекислотой производитс ка дополнительном приспособлении.The known process for producing casting molds of rods without drying is carried out by chemically hardening the mixture on liquid glass with gaseous carbon dioxide. In this case, the mixture is compacted in a flask or a core box and is produced on a shaking or sanding machine with a Noah machine, and the compressed mixture is blown with carbon dioxide by an additional device.
Предлагаемый способ отличаетс тем, что операци уплотнении смеси совмещаетс с операцией продувки ее углекислыл газом, сжатым до 4-6 кг/см. Это позвол ет повысить производительность процесса и снизить расход газа и себестоимость формовки.The proposed method is characterized in that the operation of compacting the mixture is combined with the operation of purging it with carbon dioxide and gas, compressed to 4-6 kg / cm. This makes it possible to increase the productivity of the process and reduce gas consumption and the cost of molding.
Приготовление литейных форм и стержней сводитс к одной операции- продувке газообразной углекислотой смеси, предварительно насыпанной в опоку или стержневой щик. При этом формовочна смесь получает нужное уплотнение и одновременно твердеет вследствие реакции между жидким стеклом и углекислотой.The preparation of casting molds and cores is reduced to a single operation — purging with gaseous carbon dioxide a mixture previously poured into a flask or core box. At the same time, the molding mixture obtains the necessary compaction and at the same time hardens due to the reaction between liquid glass and carbon dioxide.
Предмет изобретени Subject invention
Способ приготовлени литейных форм и стержней, отличающийс тем, что, с целью повыщени производительности и экономии расхода газа, в нем операци уплотнени смеси, содержащей жидкое стекло, совмещаетс с операцией продувки углекислым газом, сжатым до 4-6 кг/см.The method of preparing casting molds and cores, characterized in that, in order to increase productivity and save gas consumption, in it the operation of compacting a mixture containing liquid glass is combined with the operation of blowing carbon dioxide compressed to 4-6 kg / cm.
