Abstract
Изобретение относитс к литейному производству, в частности к литью в металлические формы. Цель изобретени - повышение надежности. Стержень содержит обоймы 2с основанием 3 и крышкой, между которыми размещены сектора 5, взаимосв занные между собой с помощью клиньев 6, а также стержень 7 с рым-болтом и силовыми элементами. Клинь 6 установлены с радиальным зазором h относительно обоймы, при этом на поверхности секторов, сопр женных с клинь ми, выполнены фаски, глубина , а которых превышает упом нутый радиальный зазор h. Конструкци стержн обеспечивает такое сопр жение его элементов , которое в процессе лить исключает зацеп отливки стержнем, чем предотвращаетс их разрушение при извлечении отливки . 2 ил..The invention relates to foundry, in particular to casting in metal molds. The purpose of the invention is to increase reliability. The rod contains clips 2 with a base 3 and a lid, between which sectors 5 are interconnected, interconnected by means of wedges 6, and also the rod 7 with an eyebolt and power elements. The wedge 6 is installed with a radial clearance h relative to the clip, while chamfers are made on the surface of the sectors adjacent to the wedges, the depth of which exceeds the mentioned radial clearance h. The design of the rod provides a mating of its elements, which in the process of casting eliminates the hook of the casting rod, which prevents their destruction when removing the casting. 2 or ..
