The lower flask 29 and upper flask 29' formed by the upper mold or lower mold molding machines 2 and 6 are brought together midway, further weighted, and poured, and then transferred to the second traverse 1.
2 to the first station position of the cooling line 11, the upper and lower flasks 2 that have been poured
9'' is sent to the first cooling pool line 19 via the transfer traverser 20, and is transferred to the first cooling pool line 19 by the operation of the pusher cylinder 26.
The material is fed upward in the direction of the arrow to the conveyance end. Next, it is sent to the second cooling pool line 21 through the cooling mold transfer device 23, and by the operation of the pusher cylinder 27, it is sent to the conveying end on the second cooling pool line 21, and then to the cooling mold return device 24. Therefore, it is sent to the extension line of the first cooling pool line 19, and transferred onto the switching traverser 20 by the operation of the pusher cylinder 26,
Furthermore, it is sent onto the cooling line 11 via this switching traverser 20 . Thereafter, the weight is removed by the weight transfer device 10, and the mold is disassembled by being sent along the cooling line 11 to the mold disassembly device 13, where the surface plate is removed and the upper and lower flasks 29'' are now empty.
The flask is separated into an upper flask 29' and a lower flask 29, which are sent to the upper or lower molding machines 6, 2 via the upper or lower molding lines 4, 1, respectively, and are reused. Further, the surface plate is returned to the surface plate return device 15 via the surface plate return line 30. In addition, if a longer cooling time is required, the third cooling pool line 22 can be used to connect the second or third cooling pool line 22 to the third cooling pool line 22.
1 and 22 alternately.
