Abstract
A temperature adjustment mold for a blow molding apparatus provided with at least an injection molding unit that injection-molds a preform made of a resin and having a bottomed shape, a temperature adjusting unit that adjusts a temperature of the preform manufactured by the injection molding unit, and a blow molding unit that blow-molds the preform to manufacture a resin container, the temperature adjustment mold including a cavity mold that accommodates the preform, and an air introduction member that includes a fitting core and a rod member with a multiple-tube structure to form at least three concentric air flow paths.
Claims6
A temperature adjustment mold for a blow molding apparatus provided with at least an injection molding unit that injection-molds a preform made of a resin and having a bottomed shape, a temperature adjusting unit that adjusts a temperature of the preform manufactured by the injection molding unit, and a blow molding unit that blow-molds the preform to manufacture a resin container,
- the temperature adjustment mold comprising:
- a cavity mold that accommodates the preform;
- and
- an air introduction member that includes a fitting core and a rod member with a multiple-tube structure to form at least three concentric air flow paths,
- wherein the rod member has at least an inner rod member and an outer rod member, each of which is hollow and cylindrical,
- wherein an axial length of the outer rod member is shorter than an axial length of the inner rod member, and
- wherein the air flow paths include at least a first flow path formed inside the inner rod member, a second flow path formed between the inner rod member and the outer rod member, and a third flow path formed between the outer rod member and the fitting core.
A temperature adjustment mold for a blow molding apparatus provided with at least an injection molding unit that injection-molds a preform made of a resin and having a bottomed shape, a temperature adjusting unit that adjusts a temperature of the preform manufactured by the injection molding unit, and a blow molding unit that blow-molds the preform to manufacture a resin container,
- the temperature adjustment mold comprising:
- a cavity mold that accommodates the preform;
- and
- an air introduction member that includes a fitting core and a rod member with a multiple-tube structure to form at least three concentric air flow paths,
- wherein the fitting core and the rod member are connected to a fixing block with air supply port and air exhaust port.
A blow molding apparatus comprising:
- an injection molding unit configured to injection-mold a preform made of a resin and having a bottomed shape;
- a temperature adjusting unit configured to adjust a temperature of the preform manufactured by the injection molding unit;
- and
- a blow molding unit configured to blow-mold the preform adjusted in temperature to manufacture a resin container,
- wherein the temperature adjusting unit has:
- a cavity mold that accommodates the preform;
- and
- an air introduction member that includes a fitting core and a rod member with a multiple-tube structure to form at least three concentric air flow paths in the preform to cool the preform,
- wherein the rod member has at least an inner rod member and an outer rod member, each of which is hollow and cylindrical, and
- wherein the air flow paths include at least a first flow path formed inside the inner rod member, a second flow path formed between the inner rod member and the outer rod member, and a third flow path formed between the outer rod member and the fitting core.
