Description
Известен способ прецизионного (точного) лить по авт. свидетельству № 77343, заключающийс в формовке специальным наполнителем восковой модели, просушке формы, подогреве ее и вытапливании воска, прокаливании формы и заливке в гор чую форму жидкого металла, с последующим разрушением формы и извлечением полученной отливки. Этот способ характеризуетс высокой точностью и чистотой отливки, он допускает отливку стальных тонкостенных деталей со сложной конфигурацией . Однако стоимость отливки и по этому способу весьма высока , а отливка больших деталей очень сложна.There is a method of precision (accurate) cast by ed. certificate no. 77343, which consists in molding a wax model with a special filler, drying the mold, heating it and melting the wax, calcining the mold and pouring the liquid metal into the hot mold, followed by destroying the mold and extracting the resulting casting. This method is characterized by high precision and purity of the casting, it allows the casting of steel thin-walled parts with a complex configuration. However, the cost of casting and this method is very high, and the casting of large parts is very complex.
Существует также способ лить в кокиль, отличающийс чистотой и низкой стоимостью отливки. Но он не позвол ет получать детали сложной конфигурации и тонкостенные, особенно стальные.There is also a chill casting method that is clean and has a low casting cost. But it does not allow obtaining details of complex configuration and thin-walled, especially steel.
Предлагаетс способ прецизионно-кокильной отливки стальных и чугунных деталей, сочетающий преимущества описанных способов отливки .A precision chill casting method for steel and cast iron parts is proposed, combining the advantages of the described casting methods.
Жидкий металл заливаетс в составную комбинированную форму, состо щую из опоки с цементной формой / части 2 детали 3, заформованной по восковой модели (по технологии изготовлени форм дл прецизионной отливки) и из разъемной металлической формы - кокил 4 и части 5 детали 3.The liquid metal is poured into a composite combined form consisting of a flask with a cement mold / part 2 of part 3, molded according to a wax model (according to the technology of making molds for precision casting) and from a detachable metal mold — chill mold 4 and part 5 of part 3.
После заливки металлом формы кокиль 4 освобождаетс от части 5 отлитой детали 3 и монтируетс с новой опокой / дл следующей заливки , а залита цементна форма части 2 детали 3 разрушаетс полностью , освобожда отлитую деталь от формы.After the metal is poured into the mold, the chill 4 is released from part 5 of the cast part 3 and is mounted with a new flask / dl for the next fill, and the cement form of part 2 of part 3 is completely cast down, freeing the cast part.
