Description

Основным способом изготовлени  металлических форм до сих пор  вл етс  способ механической обработки путем резани  на универсальном нли специальном оборудовании с частыми случа ми применени  ручных граверных работ дл  доделки форм.The main method of manufacturing metal molds so far is the method of machining by cutting on universal equipment or special equipment with frequent use of hand engraving for finishing forms.

В цел х удешевлени  и ускорени  процессов изготовлени  форм примен ютс  следующие методы;In order to reduce the cost and speed up the manufacturing processes of the forms, the following methods are used;

а)холодное выдавливание форм;a) cold extrusion of forms;

б)отливка форм;b) casting molds;

в)электроэррозионный снособ.c) electroerosion method.

Способ холодного выдавливани  неудобен тем, что т 1ебуст применени  мощных гидропрессов и сложных, дорогих, термически обработанных мастер-пуансонов. Работа но этому способу технически не безопасна , а пуансоны крайне недолговечпы.The cold extrusion method is inconvenient in that it involves the use of powerful hydraulic presses and complex, expensive, heat-treated master punches. Work but this method is not technically safe, and the punches are extremely short-lived.

Отливка форм в землю без дальнейн1еп мехапическон обработки их допустима только дл  нзготовлени  весьма грубых кокилей.Casting molds into the ground without further machining them is permissible only for the preparation of very rough molds.

Электроэррозионный снособ неудобен тем, что дл  него необходимо изготовленне металлического электрода сложной формы; долговечность электрода крайне мала. Форма требует последующей электрополировки . Необходима  стеиень точности не всегда может быть обеспечена без последующей механической доделки.The electroerosion removal method is inconvenient because it requires the manufacture of a metal electrode of complex shape; the durability of the electrode is extremely small. The form requires subsequent electropolishing. The required degree of accuracy can not always be provided without a subsequent mechanical finishing.

В описываемом пзобретенпн зтн недостатки устранены тем, что деталь или ее модель покрывают пульверизируемым мета.тлом и тюлученный отпечаток формы детали используют в качестве кокил  дл  производства лить .In the described invention, the shortcomings are eliminated by the fact that the part or its model is coated with a pulverized meta.tl and the translucent shape imprint of the part is used as a mold for the production of casting.

Дл  получени  детали описываемым способом изготовл ют ее образец из материала, который способен выдерживать температуру до 61Г и удар частичек пульверизуемого конструкционного материала (например; гипс, алюминий, свинец, сталь, медь, пластинки и т. п.). Когда изготавливают специальный образец детали или модель внутреннем полости формы, их раздел ют на части в соответствии с будущими плоскост ми разъема формы.To obtain a part using the described method, its sample is made from a material that is able to withstand temperatures up to 61 ° C and the impact of particles of a pulverized structural material (for example; gypsum, aluminum, lead, steel, copper, plates, etc.). When a special sample is made of the part or model of the internal cavity of the mold, they are divided into parts in accordance with the future planes of the shape plug.

Каждую такую часть располагают на подмодельпой доске :t покрывают слбсл выбранного конструкционного материала любым пульреризациониым способом, обеспечивающим сохранность модели и иапесени  сло  необходимой толшкпы и заданных физико-хи.мпчсских свойств.Each such part is placed on a submodel board: t cover the following areas of the selected structural material in any pulverization method, ensuring the safety of the model and the sand layer of the necessary thickness and given physical and chemical properties.

После окончани  процесса пульверизации полученные отпечатки освобождаютс  от моделей и поступают на общую сборку изделн  (например , кокил  или какой-либо другой формы). Никакой механической или ручной доделки рабоча  оформл юща  поверхность формы не требует.After the completion of the spraying process, the resulting prints are freed from the models and are fed to the general assembly of products (for example, a metal mold or some other form). Working with the surface of the mold does not require any mechanical or manual finishing.

Описываемым способом нульверизации могут быть изготовлены кокили и прессформы как дл  деталей с симметричиым геометрическим профилем, так и с несимметричным.In this nullization method, chills and molds can be made for parts with a symmetrical geometric profile, or with asymmetrical.
