Description
Прецизионное и художественное литье в основном производ т по выплавл емым модел м деталей и литниковых систем. Разогревание и расплавление этих моделей при нагреве форм происходит неравномерно в разл нчных ее част х вследствие различной толпхины формы, при .шгающеи -к част м выплавл емых м.о(делей.Precision and art castings are mainly produced using melted models of parts and gating systems. The heating and melting of these models during the heating of forms occurs unevenly in different parts of it due to the different form of the mold, with chunks being made to parts of the melted mo.
Так, например, в местах, расположенных ближе к поверхности опоки , расплавление происходит раньше, чем в местах, расположенных ближе к центру опоки. Таким образом, частично расплавленна композици не может сразу вытекать из формы.For example, in places located closer to the surface of the flask, melting occurs earlier than in places located closer to the center of the flask. Thus, the partially molten composition cannot immediately flow out of the mold.
Воскова композици имеет больший коэффициент расширени , чем материал формы, вследствие чего расплавленна масса производит значительное давление на огнеупорный слой формы, который деформируетс в результате этого давлени , образу вм тины и треш,ины и тем самым искажа поверхность и размеры отливки.The wax composition has a greater coefficient of expansion than the mold material, as a result of which the molten mass produces significant pressure on the refractory layer of the mold, which deforms as a result of this pressure, forming indentation and trash, thereby distorting the surface and dimensions of the casting.
По предлагаемому способу, в цел х предохранени огнеупорного СЛОЯ формы от разрушени 1И искажени при выплавке легкоплавкой композиции, выплавл емые модели деталей и литниковых систем изготовл ютс ПОЛЫМИ. Благодар этому, расширение материала легкоплавких моделей в ранее нагреваемых участках компенсируетс полост ми модели, и так1И1м образом огнеупорный слой формы избавл етс от мелких искажений поверхности и размеров, а литье-от заливов и засоров.According to the proposed method, in order to protect the refractory layer of the form from breaking 1And the distortion during the melting of the low-melting composition, the models of parts and gating systems produced are made HALF. Due to this, the expansion of the material of the fusible models in the previously heated areas is compensated for by the cavities of the model, and thus the refractory layer of the mold also eliminates small distortions of the surface and dimensions, and the casting from bays and blockages.
Предмет изобретени Subject invention
Способ ЛИТЬЯ по выплавл емым модел м, отличающийс тем, что, в цел х предохранени огнеупорного сло формы от мелких разрывов и искажений размеров, вследствие большего коэффициента расширени материалов легкоплавких моделей, чем материала формы, и, тем самым, получени более чистой и иакаженно по размерам ОТЛИВКИ, выплавл емые модели изготовл ютс полыми.The CASTING method for the produced models, characterized in that, in order to protect the refractory layer of the form from small gaps and size distortions, due to the greater coefficient of expansion of the materials of low-melting models than the material of the form, and thereby obtaining a cleaner and more accurate COLOR SIZES, molded models are made hollow.
