Изобретение относитс ,к литейному производству и касаетс способа изготовлени литейных форм замораживанием.The invention relates to a foundry and relates to a method for producing a mold by freezing.

Известен способ изготовлени литейных форм замораживанием, который предусматривает нанесение формовочной смеси на модель с последующим уплотнением смеси и воздействием на нее хладоагентом, имеющим температуру ниже 0°С. Однако при этом способе нерационально расходуетс холод на охлаждение всей массы формы и опоки, а также больша продолжительность процесса замораживани .A known method of making casting molds by freezing, which involves applying the molding sand to the model, followed by compaction of the mixture and exposure to it with a refrigerant having a temperature below 0 ° C. However, with this method, cold is not efficiently spent on cooling the entire mass of the mold and flask, as well as the long duration of the freezing process.

Цель изобретени - оптимизаци процесса замораживани за счет образовани замороженного сло , прилегающего непосредственно к рабочей поверхности формы. Это достигаетс тем, что хладоагент непрерывно подают в полость модели.The purpose of the invention is to optimize the freezing process by forming a frozen layer adjacent directly to the working surface of the mold. This is achieved by the fact that the refrigerant is continuously fed into the cavity of the model.

На модель, снабженную полостью дл циркул ции хладоагента, устанавливают опоку. В опоку засыпают формовочную смесь, содержащую воду, и уплотн ют. В полость модели непрерывно подают хладоагент, имеющий минусовую температуру. После замораживани прилегающего к модели сло формы на необходимую глубину, форму снимают с модели и подают под заливку.A model equipped with a coolant circulation cavity is fitted with a flask. The molding mixture containing water is poured into the mold and compacted. A coolant having a minus temperature is continuously fed into the cavity of the model. After freezing the layer adjacent to the model to the required depth, the form is removed from the model and served under the fill.
