| 摘要 | PURPOSE:To execute efficiently a perforating operation with required numbers in the stage of perforating plural pieces of the holes of the same row to casting molds which are conveyed in series at the same intervals by controlling perforating devices disposed at the same pitch as the pitch of the continuous molds so as to make divided operations. CONSTITUTION:The casting molds 1 after molding and pouring are successively and continuously conveyed on a conveyor. The perforating devices 3 are fixed to a plane or three-dimensional positioning device 4 at the same intervals as the intervals of the above-mentioned casting molds under conveyance. The device 4 is set with positioning devices which can be set at optional positions according to the molding plan of the molds 1. The use of the three devices 3 is assumed here. The three holes on the left side row are first perforated within the tact time at the same intervals as the intervals of the molds 11-13. The molds are then fed by the pitch L of one flask toward the left and, for example, two holes are perforated within the tact time at the central part of each mold. The state of the molds 12-14 shown in the figure is then obtd. The molds are then fed in the same manner as mentioned above and, for example, 4 holes of the right side row are bored to the molds 13-15 and finally the perforation of all the holes necessary for the casting molds is completed. | ||||||
