PROBLEM TO BE SOLVED: To release a preform out of an injection molding device in a shorter time by moving forward a plurality of take-out plates, stopping them on a standby position just in front of the injection molding device and advancing them to the injection molding device after the mold opening of the injection molding device by using a servo motor during the injection molding carried out by the injection molding device. SOLUTION: Respective take-out plates 106a-106b are moved at high speed from the receiving position to just before the take-out position on a forward and backward driving means driving forward and backward a plurality of take-out plates 106a, 106b, 106c and 106c and 106d between the receiving position of a preform 36 and a take-out position of the same outside the injection molding device 42 by using a servo motor and a ball screw, and the speed is reduced from the position must before the receiving position. Alternatively respective release plates 106a-106b are moved forward during the injection molding by the injection molding device 42 and stopped on the standby position just before the injection molding device 42 and moved to the receiving position after the opening of the injection molding device 42. |
