METHOD FOR TRANSFERRING CASTING MOLD

PURPOSE:To improve productivity of a casting line by providing rectangular spacers having the same size as the size of the spacing between front and rear sprues and pouring a molten metal into the sprues while inserting and removing the spacers into and from the ensuing casting molds. CONSTITUTION:The front sprues A and rear sprues B are provided respectively to casting molds M1-Mn and the spacers S having the same outside size as the size of the spacing between the sprues A and B is prepd. The spacer S is first inserted and disposed between the molds M3 and M4 and in this state the entire part of the mold groups M1-Mn and the spacers S are moved by one pice of the mold in an arrow direction. After the molten metal is poured into the sprue A of the mold M4 from a pouring port T of an automatic pouring machine, the spacer S is removed and the mold M4 is moved, then the molten metal is poured into the sprue B. Pouring can be quickly and surely executed by inserting and removing the spacers S successively into and from the molds. The productivity of the casting line is thus improved.
