Technology and equipment of vertical‑stack molding for the production of castings without pattern drafts

The article reports on the new technology and equipment of vertical‑stack molding (VSM), created by OJSC “BELNIILIT” for manufacture molds. development is intended production molds cast blanks oil, which are later used piston rings internal combustion engines. difference between above‑mentioned traditional methods VSM use models without drafts. export‑oriented has a great economic effect ring manufacturers due to absence drafts castings, since part mechanical operations their processing excluded, metal consumption reduced, spaces required in this regard necessary labor supply etc. successfully carried out experimental design technological work scientific technical products creation, interest world rings. An industrial sample machine mold manipulator were manufactured.
