PLUNGER ACTUATION MECHANISM OF FORMING MOLD FOR BOTTLE MAKING MACHINE

PROBLEM TO BE SOLVED: To provide a single plunger actuation mechanism for simultaneously actuating respective plungers of plural forming molds in respective sections by adopting an electric motor having good output cost efficiency as the plunger actuation mechanism and to provide the entirely novel plunger actuation mechanism capable of exactly and efficiently forming the glass materials supplied to the respective forming molds without the occurrence of forming defects even when there are variations in the quantity of the glass materials. SOLUTION: The mechanism 10 for advancing and retreating the plungers with specified torque at the time of molding the glass forming materials G fed into the forming molds to prescribed shapes by advancing of the plungers includes the drive motor 15, a main gear 20, a planetary bevel gear 25, a first driven wheel member 30, a second driven wheel member 35, a first working pinion 4, a second working pinion 45, a first main working member 50 and a second main working member 55.
