Description

(54) ЛИТЕЙНАЯ ФОРМА ДЛЯ ЛИТЬЯ ПО ВЫПЛАВЛЯЕМЫМ(54) CASTING FORM FOR CASTING ON THE MELTED

МОДЕЛЯМMODELS

кую оболочку. После удалени  модель ной массы и прокаливани  оболочково формы, в нее заливайт металл. При этом, знакова  часть стержн  2 при его термическом расширении свободно перемещаетс  в отверстии насадки 3, даже в случае короблени  стержн  благодар  .обратному уклону 4 на внутренней поверхности насадки.which shell. After removing the model mass and calcining the shell mold, pour metal into it. At the same time, the sign part of the rod 2, when thermally expanded, freely moves in the hole of the nozzle 3, even if the rod is warped due to reverse bias 4 on the inner surface of the nozzle.

Таким образом, насе1дка в форме исключает попадание металла в эаэор между формой и стержнем, и имеет преимущество - исключает возможность защемлени  стержн , расшир ющегос  при заливке металла.Thus, the uniform in the mold eliminates the ingress of metal into the eaaor between the mold and the rod, and has the advantage of eliminating the possibility of pinching the rod expanding when the metal is cast.

Применение формы по описываемому изобретению позволит снизить брак по разностенности от.ливок и сократить потери Форм.The use of the mold according to the described invention will allow to reduce the scrap of the difference in thickness from the castings and reduce the loss of Forms.
