Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ ЖТЕЙНЫХ ФОРМ(54) METHOD OF MANUFACTURING PLAIN FORMS
Изобретение относитс к литейному производству и может быть использовано при изготовлении литейных форм по вакуум-процессу. Известен способ изготовлени литейных форм, согласно которому на модель нанос т синтетическую пленку, устанавливают опоку, в которую засыпают огнеупорный, не содержащий крепител материал, покрывают опоку свер ху другой синтетической пленкой, подключают полость формы к источнику, создающему разрежение, после чего модель удал ют 13. Недостатком этого способа вл етс невозможность изготовлени сложных литейных форм. Известен также способ, в соответст вии с которым синтетическа пленка образуетс нанесением жидкой синтетической смолы на модель, покрытую припылом L 2 J. Известен способ изгот овлени литей ных форм, согласно которому на модель наноситс покрытие из мелкозернистого материала, смешанного с твердеющим св зующим. Далее засыпаетс наполнитель , а остальные операции традиционны З. Наиболее близким к предлагаемому вл етс способ изготовлени литейных форм, включающий напыление подогретого полиэтилена на модель, установку опоки, заполнение опоки огнеупорным наполнителем, вакуумирование и удаление модели f4j. Недостатками этлгр способа вл ютс затрудненный съем формы с модели, вследствие чего может быть разрушено герметизирующее покрытие форм, и невозможность изготовить формы сложной конфигурации с глубокими впадинами и большими выступами. Таким способом трудно изготавливать литейные формы сложной конфигурации. Цель изобретени - изготобление сложных форм с глубокими впадинамиThe invention relates to foundry and can be used in the manufacture of casting molds according to the vacuum process. A known method for making casting molds, according to which a synthetic film is applied to a model, is installed on a flask in which a refractory material that does not contain anchoring material is poured, cover the flask with another synthetic film, connect a mold cavity to a vacuum source, and then remove the model 13. The disadvantage of this method is the impossibility of making complex casting molds. A method is also known, in accordance with which a synthetic film is formed by applying a liquid synthetic resin on a model coated with L 2 J dust. A known method for the manufacture of casting molds, according to which the model is coated with a fine-grained material mixed with a hardening binder. Next, the filler is filled up, and the remaining operations are traditional. The closest to the present invention is a method of making casting molds, including spraying preheated polyethylene onto the model, setting the flask, filling the flask with refractory filler, evacuating and removing the f4j model. The disadvantages of this method are the difficulty in removing the molds from the model, as a result of which the sealing coating of the molds can be destroyed, and the impossibility of producing molds of a complex configuration with deep depressions and large protrusions. In this way, it is difficult to manufacture casting molds of complex configuration. The purpose of the invention is the manufacture of complex forms with deep depressions.
