摘要： A blow molding machine assembly configured to be mounted to a blow molding machine to move a mold base configured to form a container base. The blow molding machine assembly includes an over-stroke cylinder and a counter-stretch rod. The over-stroke cylinder is configured to move the mold base between an extended base position and a retracted base position. The counter-stretch rod is movable between a retracted rod position in which the counter-stretch rod does not extend out from within the mold base, and an extended rod position in which the counter-stretch rod extends out from within the mold base.

摘要： 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.

摘要： A parison supply device that continuously supplies, to a blow molding die, parison sections of a parison discharged from an extrusion die, the parison section having a specified length. The parison supply device includes a plurality of tension chucks and a tension chuck operation unit that operates the plurality of tension chucks. The tension chuck operation unit causes the individual tension chucks to perform a repeated operation of grasping the parison at a first position near the extrusion die and moving to a second position separated from the extrusion die such that, before the preceding tension chuck is separated by a set distance from the extrusion die at the second position, the following tension chuck grasps the parison at the first position, and then the parison section is supplied to the blow molding die.

摘要： The blow molding device includes a heating section that continuously transfers and heats preforms that respectively include a neck along a heating transfer path while supporting the preforms using transfer members in an inverted state, a blow molding section that simultaneously blow-molds N (N is an integer equal to or larger than 2) preforms that have been heated by the heating section in an upright state to form N containers, and an intermittent transfer section that intermittently transfers the N preforms from the heating section to the blow molding section. The intermittent transfer section includes a pitch conversion section that converts the arrangement pitch of the N preforms from a first pitch P1 to a second pitch P2 (P2>P1), and an inversion section that includes N inversion arms that respectively invert the N preforms from the inverted state to the upright state.
