Изобретение относитс  к литейному производству , в частности дл  выполнени  вентил ционных каналов в литейных формах.The invention relates to a foundry, in particular for forming ventilation ducts in a mold.

Известно приспособление дл  выполнени  вентил ционных каналов в формах, включающее цилиндрический стержень, на одном конце которого расположена руко тка, а другое выполнено на конус.A device for making ventilation ducts in molds is known, which includes a cylindrical rod, at one end of which a handle is located and the other is tapered.

Однако при извлечении приспособлени  из формы слой, прилегающий к каналу, разрушаетс .However, when removing the mold from the mold, the layer adjacent to the channel is destroyed.

При этом комочки смеси, попада  в жидкий металл при заполнении им формы, могут стать причиной брак отливки по засорам.In this case, lumps of the mixture, falling into the liquid metal when filling the mold with it, can cause the casting to reject the blockage.

С целью уменьшени  возможности разрушени  верхнего сло  формы предлагаемое приспособление снабжено свободно установленной на цилиндрическом стержне фиксируемой оправкой, поверхность которой, контактирующа  при работе со смесью, имеет коническую форму.In order to reduce the possibility of destruction of the upper layer of the mold, the proposed fixture is provided with a fixed mandrel freely mounted on a cylindrical rod, the surface of which, in contact with the mixture, has a conical shape.

Па чертеже изображено предлагаемое приспособление .Pa drawing shows the proposed fixture.

Приспособление состоит из цилиндрического стержн  /, руко тки 2, конической части 5 и оправки 4, рабоча  поверхность которой выполнена конической.The device consists of a cylindrical rod /, a handle 2, a conical part 5 and a mandrel 4, the working surface of which is made conical.

Оправка 4 свободно установлена на цилиндрическом стержне / и имеет фиксатор 5, например, в виде крыльчатой гайки с винтом. The mandrel 4 is freely mounted on a cylindrical rod / and has a retainer 5, for example, in the form of a wing nut with a screw.

При введении приспособлени  в форму рабоча  ее поверхность оставл ет конический отпечаток, упрочн ющий слой формы, прилегающий к вентил ционному каналу.When a device is inserted into a form, its working surface leaves a conical imprint, reinforcing the form layer, adjacent to the ventilation duct.

При извлечении приспособлени  из формы его конусна  часть свободно выйдет из формы без скольжени  по поверхности канала, чем предохранит форму от разрушени .When removing the mold from the mold, its conical part will freely leave the mold without sliding on the channel surface, thus preventing the mold from breaking.

Длину каналов регулируют путем изменени  расположени  оправки 4 на цилиндрическом стержне / и фиксации ее фиксатором 5.The length of the channels is adjusted by changing the position of the mandrel 4 on the cylindrical rod and fixing it with the latch 5.
