摘要： A blow molding apparatus for manufacturing a resin container by blow molding a preform having a bottomed cylindrical shape includes: a pair of mold clamping plates that openably and closably supports a pair of blow split molds accommodating the preform; linear motion mechanisms that drive the pair of mold clamping plates in an opening and closing direction and apply a mold clamping force to the mold clamping plate at a time of mold closing; and a lock member that interferes with a lower end side of the mold clamping plate at a mold closing position of the blow split mold and restricts movement of the mold clamping plate in a mold opening direction.

摘要： In this invention, a blow nozzle (30), which introduces blow air into a molded article (20) in which a flange portion (22B) provided around a neck portion (22) is supported by a blow cavity mold (10), includes a nozzle main body (50) and an outer nozzle (80) connected integrally to the nozzle main body and disposed around a circumference of the neck portion. The outer nozzle includes a first surface (84) brought into press contact with the flange portion and continuing in a circumferential direction and a second surface (86) disposed further outwards in a radial direction than the first surface and being brought into contact with the blow cavity mold. From when the nozzle main body is moved and the first surface is brought into contact with the flange portion to when the second surface is brought into contact with the blow cavity mold and the movement of the nozzle main body is stopped, the first surface of the outer nozzle is overdriven so that the flange portion is airtightly sealed by the first surface.

摘要： An object of the invention is to provide a blow mold unit and a blow molding machine which can stabilize a bottom mold clamping motion to thereby mitigate loads to be applied to a bottom mold driving mechanism and molds.
A blow mold unit (10) has a construction in which, when clamping first and second blow cavity split molds (12, 14) which are fixed to first and second fixing plates (40, 50) and bottom molds (100) which are fixed to a bottom mold fixing plate (10), pressure receiving members (60) fixed to the first and second fixing plates (40, 50) are brought into engagement with the bottom plate fixing plate (110). Guide plates (120) are fixed to the bottom mold fixing plate (110), and guided members (70) capable of being brought into abutment with the guide plates (120) are supported by first and second pressure receiving plates (20, 30). The bottom mold fixing plate (110) includes a first connecting portion (116) to be connected to a bottom mold opening/closing unit (210) which is to be driven by a clamping mechanism provided to a blow molding machine, and a second connecting portion (116) to be connected to a moving and biasing member (250) which is provided to the blow molding machine (200) and moves and biases the bottom molds, which are in the closed position, in a direction in which the bottom molds are closed.-

摘要： A method for manufacturing a resin container having an undercut shape includes accommodating a preform in a cavity mold having an undercut part; inserting a core mold to an inner side of the preform; introducing blow air into the preform through the core mold to blow-mold the preform into a container; gripping a neck part of the container, in which the core mold is disposed on an inner side, with a conveyance chuck from an outer side and sandwiching the neck part of the container with the core mold and the conveyance chuck; and opening the cavity mold. The container in which the neck part is sandwiched between the core mold and the conveyance chuck is released from the undercut part by the opening of the mold.

摘要： A mold includes a position adjustment mechanism that receives a shaft portion extending from a cavity mold, which accommodates a preform, and adjusts a position where the cavity mold is held on a plane intersecting an extending direction of the shaft portion. The position adjustment mechanism includes a first member in which a linear cam hole that receives the shaft portion is formed, and a second member that is disposed to overlap the first member in the extending direction of the shaft portion and rotates with respect to the first member along a plane. The second member has an elongated hole that intersects the cam hole in a direction of the plane and positions the shaft portion together with the cam hole. Further, a position where the cam hole and the elongated hole intersect each other moves along a longitudinal direction of the cam hole by rotation of the second member.
