Claims (2)

1. Способ изготовления форм для литья по выплавляемым моделям из фотополимеризирующихся материалов, включающий нанесение на фотополимеризирующуюся модель твердой оболочки из термостойкой композиции, нагрев фотополимеризирующейся модели с твердой оболочкой до температуры выгорания материала модели и выдержку в заданном интервале температур для полного удаления продуктов сжигания, отличающийся тем, что нагрев фотополимеризирующейся модели ведут в два этапа: на первом этапе в области низких температур внутри твердой оболочки поддерживают восстановительную атмосферу, причем в конце этапа делают изотермическую выдержку, а на втором этапе в области высоких температур и в процессе выдержки при высокой температуре создают окислительную атмосферу.1. A method of manufacturing investment casting molds from photopolymerizable materials, including applying a hard shell to a photopolymerizing model from a heat-resistant composition, heating a photopolymerizing model with a hard shell to the burnout temperature of the model material and holding it in a predetermined temperature range to completely remove combustion products, characterized in that the photopolymerizing model is heated in two stages: at the first stage, in the low-temperature region inside the hard shell, vayut reducing atmosphere, wherein at the end of stage make isothermal exposure, and the second stage at high temperatures and during exposure to high temperature, produce an oxidizing atmosphere. 2. Способ изготовления форм для литья по выжигаемым моделям из фотополимеризирующихся материалов по п. 1, отличающийся тем, что температура разграничения первого и второго этапов находится в интервале 300 - 500°С. 2. A method of manufacturing casting molds for burnable models from photopolymerizable materials according to claim 1, characterized in that the delineation temperature of the first and second stages is in the range of 300 - 500 ° C.
