Polymerization is performed on the lower mold placed on 1 to complete the mold 17. The mold 17 is transported to the position facing the pouring machine 43 by the mold transport device 16 and poured, and the poured mold 17 transports the other straight portion 2b of the transport path 2 of the mold transport device 16 by one pitch. While being cooled, the cooled mold 17 is carried into the frame separating machine 44 and separated from the casting frame, and the product is taken out from the foundry sand. The separated upper and lower casting frames are returned to the mold conveying carriage 1 and carried into the frame separating machine 45.

図16において、鋳型搬送装置16の搬送径路2に沿って造型機46、重り・ジャケット乗せ替え機47、注湯機48が適宜間隔で配置され鋳造装置40が構成されている。造型機46では鋳枠を使用しないで砂のみを圧縮した鋳型17が造型されて搬送台車1上に搬出される。搬送台車1は1配列ピッチAずつ間歇的に移動され、鋳型17が重り・ジャケット乗せ替え機47まで搬送されると、注湯時に鋳型17が破壊、或いは上下鋳型が分離することを防止するために、重り・ジャケット乗せ替え機47によりジャケットが鋳型17の外周に嵌め込まれ、重りが鋳型17上に載置される。重り、ジャケットが装着された鋳型17は、鋳型搬送装置16により注湯機48と対向する位置に搬送されて注湯され、注湯された鋳型17は鋳型搬送装置16の搬送径路2の他方の直線部2bを1ピッチずつ搬送される間に冷却され、冷却した鋳型17は、搬送径路2の両側直線部2bに跨って配設された重り・ジャケット乗せ替え機47に搬入され、重り及びジャケットが取り外され、製品が鋳物砂から取り出される。外された重り及びジャケットは他方の直線部2bに移送され、新規に造型された鋳型17に装着される。   In FIG. 16, a molding machine 46, a weight / jacket changing machine 47, and a pouring machine 48 are arranged at appropriate intervals along the conveying path 2 of the mold conveying apparatus 16 to constitute a casting apparatus 40. In the molding machine 46, a mold 17 in which only sand is compressed is formed without using a casting frame, and is carried out onto the transport carriage 1. The transport carriage 1 is moved intermittently by one arrangement pitch A to prevent the mold 17 from being broken or the upper and lower molds from being separated when the mold 17 is transported to the weight / jacket changer 47. Further, the weight / jacket changing machine 47 fits the jacket onto the outer periphery of the mold 17, and the weight is placed on the mold 17. The mold 17 fitted with the weight and the jacket is transported and poured into a position facing the pouring machine 48 by the mold transport device 16, and the poured mold 17 is poured into the other side of the transport path 2 of the mold transport device 16. The casting mold 17 is cooled while being conveyed by one pitch at a straight portion 2b, and the cooled mold 17 is carried into a weight / jacket changing machine 47 disposed across the straight portions 2b on both sides of the conveying path 2, and the weight and jacket Is removed and the product is removed from the foundry sand. The removed weight and jacket are transferred to the other straight portion 2b and mounted on a newly formed mold 17.
