PURPOSE:To mold a molding efficiently by computing the heating time of a mold from the feed-out temperature of the mold out of a heating furnace provided in a heating station, the temperature of the mold before feeding the same into the heating furnace and the temperature in the heating furnace before feeding in the mold and adjusting the waiting time of the mold based on the heating time. CONSTITUTION:The feed-out temperature T1 of a mold 12 out of a heating furnace 30 provided in a first heating station 14 is set based on the characteristics data of the mold 12 such as the material quality and shape. The temperature T2 of the mold 12 before feeding into the heating furnace 30 is sensed by a radiation thermometer disposed in a first elevator station 24. The temperature T3 in the heating furnace 30 before the mold 12 is fed in is sensed by a temperature sensor. Through the temperature information on the feed-out temperature T1 out of the furnace, the temperature T2 and the temperature T3, the heating time A of the mold 12 is computed by a control device 29. Then, the computed heating time A and the reference heating time A' are compared with and the waiting time B in a releasing station 22 is adjusted. |
