い、２〜５シヨツトにおいて、前のショットの成形結果
とこれまでに学習によって得られた成形機の成形条件に
対応した操作量との２つの項から、その時の操作量を決
定してもよい。この場合、樹脂成形機７が異常のときに
は次のショットに異常を反映でき不良を防止できる。Furthermore, in the above embodiment, the operation amount of the injection hydraulic pressure is modified based only on the molding results under the same molding conditions, but the first shot when molding is started is performed in the same manner as in the above embodiment, and the second shot is performed in the same manner as in the above embodiment. -5 shots, the operating amount at that time may be determined from two terms: the molding result of the previous shot and the operating amount corresponding to the molding conditions of the molding machine obtained by learning so far. In this case, when the resin molding machine 7 is abnormal, the abnormality can be reflected in the next shot and defects can be prevented.
以上詳述したようにこの発明によれば、成形条件の変動
、特に型温の変動の大きい打ち始めにおいて容易に不良
の発生を防止することが可能となる優れた効果を発揮す
る。As described in detail above, the present invention exhibits an excellent effect in that it is possible to easily prevent defects from occurring at the beginning of molding, where there are large fluctuations in molding conditions, especially mold temperature.
