PURPOSE:To cut by half a cooling time in a main die and to enhance an injection cycle by using a plurality of dies and mold clamping units and taking out a parison from the die before this parison is completely cooled and molded into a prescribed shape and transferring the parison to the other die and performing reblowing and recooling thereof. CONSTITUTION:A parison is blow-molded by the injection head 1 of a main die 2 and cooled in the outside of this main die 2 by using a recooling die 4. A blow molding die 2 for molding a fuel tank made of resin is equipped with ordinary mold clamping units 3 and the injected parison is held in a prescribed shape. At this time, before the parison is completely cooled and molded into the prescribed shape, a product carrier traverser 5 is operated in the minimum time capable of taking out the parison. The parison is taken out from the die 2 and transferred to the other recooling die 4 to perform reblowing and recooling. When the parison is molded into a prescribed shape herein, it is sent to a primary working line 6 by the product carrier traverser 5. |
