Description

Известные литниковые системы дл  отливки индивидуальных поршневых колец имеют р д недостатков. Так, литникова  чаша имеет такую форму, котора  не обеспечивает задержани  шлака до ноступлени  металла в сто к. С целью избежани  попадани  шлака в форму, литникова  система имеет перед каждым поршневым кольцом шлакоуловитель значительных размеров, что вызывает необходимость иметь сто к больших размеров, кроме того, большие местные скоплени  металла вызывают его неоднородность в отливках по твердости.The known gating systems for casting individual piston rings have several disadvantages. Thus, the gating bowl has a shape that does not ensure slag retention until metal reaches a hundred K. To avoid slag getting into the form, the gating system has a large-sized slag trap in front of each piston ring, which makes it necessary to have a hundred to large sizes, besides Large local accumulations of metal cause its heterogeneity in hardness castings.

В описываемой ли1никовой системе эти недостатки устранены тем, что литникова  система состоит из литниковой чаши, имеюшей такую геометрию формы, котора  обеспечивает удерл ание шлака от поступлени  его в сто к 1вместе с металлом, а шлакоуловители на питателе образуютс  перед каждой предыдушей нижней опокой путем простановки земл ных выступаюших болванчиков, перерезываюших литниковые ходы в нижележаших опоках.In the described system, these deficiencies are eliminated by the fact that the gating system consists of a gating bowl that has such a shape geometry that keeps the slag from entering it a hundred to 1 along with the metal, and the slag catchers on the feeder are formed in front of each pereddushi bottom heat by casting earth stubbing jaws, re-cutting sprues in the lower flasks.

Предлагаема  литникова  система позвол ет уменьшить диаметр сто ка и шлакоуловителей с одновременным уменьшением возможноеги образовани  неоднородности отливок поршневых колец по твердости.The proposed casting system allows reducing the diameter of the sink and of the slag traps with a simultaneous decrease in the possible formation of heterogeneity of the castings of piston rings in hardness.

На фигуре показан схематический чертеж опоки, где; литникова  чаша /, выступаюшие болванчики 2, поршневое кольцо 3.The figure shows a schematic drawing of the flask, where; gutter bowl /, protruding loops 2, piston ring 3.

Предмет изобретени Subject invention

Литникова  система дл  отливки индивидуальных поршневых колец при стопочной заливке с литниковой чашей-нарашалкой обшим сто ком и питател ми, подвод ш,ими металл от сто ка к кольцу, отличающа с  тем, что, с целью уменьшени  веса металла на литниковую систему и обеспечени  повышени  однородности поршневых колец по твердости, литникова  система состоит из литниковой чаши, имеюшей такую геометрию формы, котора  обеспечивает удержание шлака от поступлени  в сто к с металлом, а шлакоуловители на питателе образуютс  -перед каждой предыдущей нижней олокой в сто ке путем простановки земл ных выступающих болванчиков, перерезывающих литниковые ходы в нижележащих опокахThe casting system for casting individual piston rings in the case of stack casting with a casting bowl of a common sink and feeders, supplying them with the metal from the sink to the ring, characterized in that, in order to reduce the weight of the metal to the casting system and to ensure an increase homogeneity of piston rings in terms of hardness, the gating system consists of a gating bowl, which has such a shape geometry that ensures the slag retention from supply to the metal and the slag-traps on the feeder are formed before each previous Oloka lower in the riser by placing the dummy protruding excavation, shear runner passages in the lower flasks
