<p>In the present invention, the loading position for parison molding is elevated and defects that occur in glass bottles are reduced. Provided is a glass bottle molding machine that press molds parisons by raising up a plunger inserted into an opening mold that is disposed at the bottom of a rough mold, wherein a spring spacer is disposed on top of a support section at the lower end of an inner sleeve that is between the plunger and an outer cylinder, so as to wind around the outer circumference of a plunger base section, and with respect to the loading position which is the position of the plunger when a gob is introduced inside the rough mold, by configuring the plunger base section to be in a floating state supported by the spring spacer, an opening section of a guide ring elevates the loading position for parison molding and reduces defects that occur in glass bottles.</p> |
