Изобретение относитс к литейному производству , а именно к изготовлению выплавл емых , выжигаемых и газифицируемых моделей .The invention relates to foundry, namely the manufacture of melted, burned and gasified models.
Известен способ изготовлени комбинированной модели, состо щий в том, что в прессформу засыпают подвспененные гранулы наполнител -пенополистирола , а потом заливают туда расплав технической мочевины.A known method of manufacturing a combined model is that the subfoam granules of the expanded polystyrene powder are poured into the mold, and then a technical urea melt is poured there.
при таком способе в местах, наход щихс па значительном удалении от заливочного отверсти , нередко застаиваетс воздух, так как гранулы пенополистирола, наход щиес вблизи заливочного отверсти прессформы , расшир ютс в первую очередь и успевают перекрыть заливочное отверстие до того, как расп/шв модельного состава вытеснит воздух из отдаленных мест прсссформы. With this method, air often stagnates in places located at a considerable distance from the filling hole, since expanded polystyrene granules located near the filling hole of the mold expand first and have time to block the filling hole before the model composition displace air from remote locations of the mold.
Целью изобретени вл етс повышение качества изготовл емой модели.The aim of the invention is to improve the quality of the manufactured model.
Это достигаетс тем, что заливку солевого расплава производ т перед засышюй в прессформу наполнител .This is achieved by pouring the molten salt before it dries into the mold filler.
При таком способе непрерывное засыпание гранул пенополистирола в солевой расплав обеспечивает очередность их термообработки: гранулы в районе заливочного отверсти ирессформы вспениваютс в последнюю очередь , что исключает преждевременное образование пробки в литниковой системе.With this method, the continuous pouring of polystyrene granules into the salt melt ensures the sequence of their heat treatment: the granules in the area of the pouring hole and the foam form foamed last, which eliminates the premature formation of a plug in the gating system.
Предмет изобретени Subject invention
Способ изготовлени комбинированной модели , включающий засыпку в преосформу наполиител -пенополистирола и заливку солевого расплава, отличающийс тем, что, с целью повышени качества изготовл емой модели , заливку солевого расплава производ т иеред засыпкой в прессформу наполнител .A method of manufacturing a combined model comprising filling in the pre-form of a polystyrene-polystyrene foam and pouring a salt melt, characterized in that, in order to improve the quality of the model being made, the casting of the salt melt is produced by filling it in the mold of the filler.
