Abstract
СПОСОБ ИЗГОТОВЛЕНИЯ ДВУХ-между моделью и наполнительнымелейных ЛИТЕЙНЫХ ФОРМ из наполни-слоем.METHOD OF MAKING TWO-between the model and the filling of the metal FOUNDRY FORMS of fill-layer.
Description
СОWITH
СХ)CX)
Известен способ изгото лени двухслойных литейных форм, заключающийс в том, что сначала изготовл ют литейную форму из наполнительной смеси по модели, размеры которой увеличены на толщину облицовочного сло , затем в зазор мезкду наполнительным слоем и моделью с размерами , обеспечивающими получение годных отливок, заливают жидкую формовочную смесь.There is a method of manufacturing a two-layer casting mold, which consists in first making a mold from a filling mixture according to a model whose dimensions are increased by the thickness of the facing layer, then pouring liquid into the gap between the filling layer and the model with dimensions that provide suitable castings. molding sand.
По предлагаемому способу наполнительный слой формы изготовл ют путем приложени давлени к диафрагме, расположенной между моделью и наполнительным слоем.According to the proposed method, the filling layer of the mold is made by applying pressure to the diaphragm located between the model and the filling layer.
Способ заключаетс в том, что перед заполнением опоки наполнительной смесью модель окружают зластичной диафрагмой, в которую послеThe method consists in the fact that before filling the flask with the filling mixture, the model is surrounded by a flexible diaphragm, into which after
заполнени опоки наполнительной смесью подают под давлением жидкост или газ, уплотн тем самым наполни5 тельную смесь. Затем давление снимают , диафрагму убирают и в образовавшийс зазор между моделью и уплотненной наполнительной смесью заливают жидкую самотвердеющую смесь,The filling of the flask with the filling mixture is supplied under pressure with a liquid or gas, thereby sealing the filling mixture. Then the pressure is released, the diaphragm is removed, and a liquid self-hardening mixture is poured into the resulting gap between the model and the compacted filling mixture,
10 приготовленную, например, из кварцевого песка, жидкого стекла, контакта Петрова и феррохромового шлака/10 prepared, for example, from quartz sand, liquid glass, Petrov contact and ferrochrome slag /
Предлагаемый способ позвол етThe proposed method allows
15 полностью механизировать операции по получению облицовочного сло в литейных формах, улучшить качество и сократить расход облицовочных смесей за счет получени более равномерного по толщине облицовочного сло .15 to completely mechanize the operations for obtaining the facing layer in casting molds, improve the quality and reduce the consumption of facing mixtures by obtaining a more uniform thickness in the facing layer.
