PURPOSE:To enhance productivity and respectively give optimum molding conditions and keep proper molding cycles even in a case that two or more types of articles different in molding conditions are molded with a single molding equipment by a structure wherein a standby station is provided at the foregoing stage of a preheating station so as to proceed each mold one by one station independently from other mold. CONSTITUTION:By releasing to stopper of a standby station 8, molds are brought into the state rollingly shiftable on travelling rails. By shifting a handling device, a mold 90 is loaded on a lift conveyer 57 to be shifted to a standby station 9 for standing-by. When a detection device recognizes that no mold is present in a preheating station 1, the mold is shifted to the mold rotating device 17 of the preheating station 1. After that, by rotating the prime mover 19 of the rotating device 17, the mold is heated with hot air blasted from hot air blasting nozzles or small orifices 16. After heating by timing for a certain period of time, the presence or absence of a mold in the following process or in a first casting station 2 is detected so as to convey the mold in the first casting station 2.
