An automatic pouring method using an automatic pouring machine for tilting a ladle that stores molten metal therein to pour the molten metal therefrom into a specified mold of a group of molds (M) that are intermittently conveyed and a controlling means for controlling the automatic pouring machine, the automatic pouring method comprising the steps of: providing data on assigned numbers of the respective molds (M) to be poured in the group of the molds, types of products (A, B) to be cast, and set weights of the molten metal to be poured, to the controlling means ; determining a set weight of the molten metal to be received by the ladle and the number of pieces of the molds (M) that could be poured with the ladle by means of the controlling means based on the provided data on the assigned numbers of the respective molds (M) to be poured in the group of the molds (M), the types of products to be cast, and the set weights of the molten metal (M) to be poured; receiving a weight of the molten metal that is greater than the set weight of the molten metal in the ladle ; deriving the difference in weight between the actual weight of the molten metal that is received in the ladle and the set weight of the molten metal in the ladle ; deriving the target weight of the molten metal to be poured by adding a value that is obtained by dividing the derived difference in weight between the actual weight of the molten metal in the ladle and the set weight of the molten metal in the ladle to the set weight of the molten metal to be poured into the mold to be poured by the number of pieces of the molds (M) that can be poured with the ladle ; tilting the ladle to pour the molten metal into the mold to be poured to target the target weight of the molten metal to be poured; and repeating the pouring of the molten metal a number of times that equals to the number of pieces of the molds (M) that could be poured with the ladle , thereby the ladle would be emptied when the last mold in the number of pieces of the molds (M) that could be poured with the ladle is poured. providing data on assigned numbers of the respective molds (M) to be poured in the group of the molds, types of products (A, B) to be cast, and set weights of the molten metal to be poured, to the controlling means ; determining a set weight of the molten metal to be received by the ladle and the number of pieces of the molds (M) that could be poured with the ladle by means of the controlling means based on the provided data on the assigned numbers of the respective molds (M) to be poured in the group of the molds (M), the types of products to be cast, and the set weights of the molten metal (M) to be poured; receiving a weight of the molten metal that is greater than the set weight of the molten metal in the ladle ; deriving the difference in weight between the actual weight of the molten metal that is received in the ladle and the set weight of the molten metal in the ladle ; deriving the target weight of the molten metal to be poured by adding a value that is obtained by dividing the derived difference in weight between the actual weight of the molten metal in the ladle and the set weight of the molten metal in the ladle to the set weight of the molten metal to be poured into the mold to be poured by the number of pieces of the molds (M) that can be poured with the ladle ; tilting the ladle to pour the molten metal into the mold to be poured to target the target weight of the molten metal to be poured; and repeating the pouring of the molten metal a number of times that equals to the number of pieces of the molds (M) that could be poured with the ladle , thereby the ladle would be emptied when the last mold in the number of pieces of the molds (M) that could be poured with the ladle is poured. <EOS>
