Изобретение относитс к литейному производству, в частности к литью в металлические формы.The invention relates to foundry, in particular to casting in metal molds.
Цель изобретени - расширение номенклатуры за счет обеспечени возможности изготовлени колес с пространственной формой лопатки.The purpose of the invention is to expand the range by making it possible to manufacture wheels with a spacial blade shape.
На фиг. 1 изображена металлическа форма дл изготовлени рабочих колес, разрез; на фиг. 2 - то же, без крышки, вид сверху, на фиг. 3 - и 4 - соответственно срезы рабочей и тыльной сторон лопаток.FIG. 1 shows a metal mold for the manufacture of impellers, a section; in fig. 2 - the same, without a cover, top view, in FIG. 3 - and 4 - respectively, sections of the working and back sides of the blades.
Металлическа форма содержит основание 1, обойму 2 и крышку 3. В обойме 2 установлены формообразующие вкладыши 4, оформл ющие лопатки. Съемна центральна вставка 5 имеет выступы 6 с пазами, оформл ющими внутренние торцы лопаток. Выступы 6 центральной вставки сопр жены с вкладышами по образующей лопатки.The metal form contains a base 1, a holder 2 and a cover 3. In the holder 2, there are installed shaping inserts 4 which form the vanes. The removable central insert 5 has protrusions 6 with grooves that form the inner ends of the blades. The protrusions 6 of the central insert are matched with inserts along the generatrix of the scapula.
Металлическа форма работает следующим образом.The metal mold works as follows.
Перед заливкой на основание 1 устанавливаютс обойма 2 и центральна вставка 5. Затем на обойме 2 размещают формообразующие вкладыши 4 и в паз обоймы 2 устанавливают крышку 3. гегалл заливаетс в отверстие в крыш хе 1„ После затвердевани металлаBefore pouring, the holder 2 and the central insert 5 are mounted on the base 1. Then, the molding inserts 4 are placed on the holder 2 and the cover 3 is installed in the slot of the holder 2. The gegall is poured into the hole in the roof 1 "After the metal has hardened

осуществл ют разборку формы в обратной последовательности и извлекают отливку.disassemble the mold in the reverse order and remove the casting.
Использование изобретени позволит обеспечить возможность изготовлени колес с пространственной формой лопатки , оформл емой центральной вставкой , имеющих повышенные эксплуатационные характеристики. Кроме того, сокращаетс трудоемкость изготовлени рабочих колес, что дает значительный экономический эффект.The use of the invention will make it possible to manufacture wheels with a blade spatially shaped with a central insert having improved performance characteristics. In addition, the complexity of manufacturing impellers is reduced, which provides a significant economic effect.
