Blow molding apparatus

A blow molding apparatus, comprising:

• an injection molding section, a cooling section, a heating section and a blow molding section, wherein
• the injection molding section injection molds a plurality of preforms at a time;
• the cooling section cools the injection-molded preforms;
• the heating section heats the cooled preforms while continuously transporting them along a transport line;
• and
• the blow molding section blow molds the heated preforms to form hollow containers,
• the blow molding section including
• a primary blow molding section which is equipped with a heat-treating blow mold and blow molds the preforms moved from the transport line into the heat-treating blow mold to form intermediate molded products, and
• a secondary blow molding section which is equipped with a final blow mold and blow molds the intermediate molded products moved from the heat-treating blow mold into the final blow mold to form hollow containers as final molded products,
• wherein an amount of time to heat treat the intermediate molded products in the primary blow molding section is different from an amount of time to form the final molded products in the secondary blow molding section,
• wherein the blow molding apparatus further comprises a grasping mechanism transport section configured to carry the preforms into the blow molding section, grasp and transport the intermediate products within the blow molding section, grasp the final molded products, and carry the final molded products out of the blow molding section to a withdrawal position, and
• wherein the grasping mechanism transport section is shared between the primary blow molding section and the secondary blow molding section.
