MACHINE FOR CASTING THIN-WALLED LARGE-SIZE PIECES

摘要

A machine for casting thin-walled large-size castings, such as panel-type parts, incorporating two leaves, one of which is fixed on a bed-plate and the other one on a movable shaft having a reversible drive, and secured on the same bed-plate. The shaft exterior is formed with a recess extending along the shaft length and further through the spacing between the leaves, the depth of the recess is adequate to accommodate the metal crust formed on the shaft surface from the moment the pouring process is started until the shaping of a piece being cast is completed; the machine leaves are provided with means for detaching and releasing the cast pieces from the half moulds.
