Casting section line body of iron mold sand-coated production line

Abstract

The invention relates to a pouring section line body of an iron mould sand coating production line. The pouring section line body comprises an automatic roller bed device, a clamping device and a pouring section line body automatic control integration system. During work, the automatic roller bed device is controlled through the pouring section line body automatic control integration system, and iron moulds which are coated with sand cavities are sequentially transferred to pouring positions; before castings are poured, upper iron moulds and lower iron moulds are firmly clamped through the clamping device, so that the internal textures of the castings are compact during the mould filing process of the castings; and after the castings are cooled, the clamping device loosens, and the iron moulds are transferred to a demoulding process by controlling the automatic roller bed device, so that the castings are taken out. By adopting the pouring section line body, the problem of vibration damage to iron mould cavities caused by long-term unilateral load bearing, deformation of side roller racks and instability during transferring processes is solved; movement of the whole iron mould sand coating production line is stable and reliable; labor intensity of workers is greatly lowered, and consistency of quality of castings can be ensured; and tension-resistance and ductility of the castings can be effectively improved.

Description

technical field [0001] The invention belongs to casting equipment, in particular to a pouring section of an iron mold sand-covered production line. Background technique [0002] In the foundry industry, the iron mold sand-coated process is used to produce ductile iron castings. The excellent performance of the products has been widely recognized by the industry. It is the guarantee to realize the lightweight of castings and the realization of replacing steel with iron. [0003] The sand-covered iron mold process produces ductile iron products. During the casting process, the molten iron will be spheroidized and inoculated. The molten iron is poured into the iron mold. Before it is completely solidified, the graphite balls formed inside the molten iron will undergo an expansion process. Here stage, the expansion force will promote the upper iron mold and the lower iron mold to separate them in reverse. If during this process, the clamping force is applied to force the upper ...
