CONTINUOUS CASTING APPARATUS FOR GRID FOR LEAD-ACID BATTERY

摘要

PURPOSE:To prevent a gate for molten metal supply from being choked up by solidifying substances of the molten metal to increase the number of cast products by forming a recessed part in the reverse direction side to the rotary direction of a rotary casting mold relative to the gate for molten metal supply. CONSTITUTION:A rotary casting mold 10 rotates in the direction of an arrow F around a driving shaft 11 as a center by a driving motor. A recessed part 7 is formed in the bottom wall part 20e of a molten metal supplying part 20 in the reverse direction to the rotary direction F of the casting mold 10 relative to a gate 50. The recessed part 7 is so formed as to open to a contacting surface 20f along the gate 50. The molten metal enters the recessed part 7 and solidifies inside and the recessed part prevents solidified substances 60 from moving. The solidified substances 60 are not conveyed to the gate 50 side and remain near the recessed part 7 even when the casting mold 10 rotates continuously. Consequently, molten lead alloy is prevented from flowing in the grooved part 10c which is in the reverse direction to the rotary direction F of the casting mold 10.
