Изобретение относитс к области литейного производства.The invention relates to the field of foundry.
Известны способы изготовлени моделей из полистирола, заключающиес в засыпке в полость пресс-формы необходимого количества гранул предварительно подвспененного полистирола с последующим окончательным вспениванием и спеканием последнего путем тепловой обмотки паром, гор чей водой, гор чим воздухом. По такому способу трудно удал ть модели из литейных форм перед заливкой металла. Модели удал ют путем выжигани . При этом из-за недостатка кислорода в полости формы, необходимого дл обеспечени полного сгорани модели, образуетс в зкий остаток, который впоследствии отрицательно вли ет на качество поверхности отливок.There are known methods for making models from polystyrene, which consist of filling the mold cavity with the required number of granules of pre-subsized polystyrene with subsequent final foaming and sintering of the latter by heat winding with steam, hot water, hot air. By this method, it is difficult to remove the models from the casting molds before pouring the metal. Models are removed by burning. In this case, due to the lack of oxygen in the mold cavity, which is necessary to ensure complete combustion of the model, a viscous residue is formed, which subsequently adversely affects the surface quality of the castings.
Дл получени модели, полностью сгорающей в процессе удалени из формы предложено модель после извлечени из пресс-формыTo obtain a model that completely burns during the removal from the mold, a model is proposed after being removed from the mold.
обрабатывать кислородом при давлении 0,5- 1,0 кгс/см.process with oxygen at a pressure of 0.5-1.0 kgf / cm.
По предлагаемому способу изготовлени литейных моделей из полистирола обеспечиваетс процесс полного выжигани моделей и не требуетс подвод кислорода извне.According to the proposed method of making casting models from polystyrene, the process of complete burning of the models is ensured and no oxygen supply from outside is required.
Способ состоит в следующем.The method consists in the following.
Обрабатывают литейные модели после извлечени их из пресс-фор.мы в герметичной камере, заполненной кислородом под давлением 0,5-1,0 кгс/см, где происходит насыщение кислородом гранул полистирола, образующих модель.Casting models are processed after they are removed from the mold in a sealed chamber filled with oxygen under a pressure of 0.5-1.0 kgf / cm, where the polystyrene granules forming the model are saturated with oxygen.
Предмет изобретени Subject invention
Способ изготовлени моделей из полистирола путем вспенивани гранул его в прессформе , отличающийс тем, что, с целью получени .модели, полностью сгорающей в процессе удалени ее из формы, модель после извлечени из пресс-формы обрабатывают кислородом при давлении 0,5-1,0 кгс/см.A method of making models from polystyrene by foaming its granules in a mold, characterized in that, in order to obtain a model that completely burns out during the removal process from the mold, the model, after being removed from the mold, is treated with oxygen at a pressure of 0.5-1.0 kgf / cm
