Abstract: One purpose of the present invention is to provide a mold unit which is capable of achieving improvements in both energy efficiency and heat resistance performance; a blow molding apparatus; and a blow molding method. The present invention is provided with: a first mold part for performing a first step in which a preform is subjected to heat-set blowing at a first temperature; and a second metal mold part for performing a second step in which an intermediate molded body blow molded as a result of the heat-set blowing is blow molded at a second temperature lower than the first temperature, to produce a container. The first mold part and the second mold part are disposed adjacently to each other.

Abstract: A mold includes a link member including a protruding grip forming part configured to form a grip part to a portion of a container by pressurizing a portion of a preform that is expanded during blow molding; and a piston member configured to move forward toward a cavity to thus press and rotate the link member. The grip forming part has: a pressurizing surface configured to pressurize the portion of the preform; and a contact surface configured to come into contact with the piston member, wherein the piston member has a pressing surface that comes into contact with the contact surface and presses the grip forming part toward an inside of the cavity when moving the pressurizing surface, and wherein the pressurizing surface is arranged at an opposite side of the contact surface of the grip forming part with respect to a moving direction of the piston member.

Abstract: A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.
Abstract translation: 吹塑成型方法包括：一次吹塑成型工序，其对包含初级温度控制部（330）的一次吹塑模具（300A）中的预成型体（200）进行成型，得到中间成型体（202），收缩步骤， 从中间成型体吹出空气以收缩中间成型制品，以及二次吹塑成型步骤，对包含二次温度控制部（430）的二次吹塑模具中收缩的中间成型体（204）吹塑成型， 得到最终的成型品。 一次吹塑步骤使用第一初级温度控制部冷却在颈部后方的中间模塑制品的第一中间成型区域，并且收缩步骤收缩温度受到控制的中间模制品的第二中间成型区域 第二初级温度控制部。
