Description

Изобретение относитс  к литейному производству , а именно к литью по выплавл емым модел м.The invention relates to foundry, namely casting on melted models.

Известен стержень дл  получени  отверстий в выплавл емых модел х, содержащий эластичную оболочку на каркасе, имеющем два знаковых элемента.A rod for producing holes in melted models is known, comprising an elastic sheath on a frame having two sign elements.

Цель изобретени  - получить в выплавл емых модел х изогнутые каналы. Это достигаетс  тем, что каркас выполнен в виде спиральной пружины, а эластична  оболочка в виде хлорвиниловой трубки, надетой на пружину .The purpose of the invention is to obtain curved channels in melted models. This is achieved by the fact that the frame is made in the form of a spiral spring, and the elastic shell is in the form of a vinyl chloride tube, worn on the spring.

На чертеже изображена полуформа с устаиовленным в ней стержнем.The drawing shows a half-form with a rod fixed in it.

Стержень содержит эластичную оболочку 1, рыполненную в виде хлорвиниловой трубки, установленной посто нно на знаковом элементе 2 и подвижно на знаковом элементе 3, каркас в виде спиральной пружины 4, вставленной в хлорвиниловую трубку 1. Один конец пружины 4 установлен подвижно на знаковом элементе 2 и посто нно на знаковом элементе 3. Внутренний диаметр трубки 1 и внешний диаметр спиральной пружины 4 одинаковы.The core contains an elastic sheath 1, rendered in the form of a vinyl chloride tube, mounted permanently on the sign element 2 and movably on the sign element 3, a frame in the form of a spiral spring 4 inserted into the vinyl vinyl tube 1. One end of the spring 4 is mounted movably on the sign element 2 and constant on the sign element 3. The inner diameter of the tube 1 and the outer diameter of the coil spring 4 are the same.

Перед заливкой стержень устанавливают в полуформу 5, фиксиру  его положение знаковыми элементами 2 и 3. После изготовлени  модели вначале вынимают знаковый элемент 3 Before pouring, the rod is installed in the half-form 5, fixing its position with the sign elements 2 and 3. After the model is manufactured, the sign element 3 is first removed

с пружиной 4. При раст жении пружины ее диаметр уменьшаетс , вследствие чего она легко извлекаетс  из трубки. Затем знаковым элементом 2 извлекают из формы оболочку. Дл  установки 4 в оболочку пружину раст гивают, при этом происходит уменьшение внешнего диаметра пружины.with spring 4. When the spring is stretched, its diameter decreases, so that it is easily removed from the tube. Then the sign element 2 is removed from the form of the shell. For installation 4 in the shell, the spring is stretched, and the outer diameter of the spring decreases.
