A core rod assembly (10) for blow molding includes a core rod head (16), a first fluid pathway (A1) extending along a first length of the core rod head (16), and a second fluid pathway (A2) extending along a second length of the core rod head (16). The first and second fluid pathways (A1, A2) may be fluidly isolated from each other and provide selective temperature control of respective first and second portions of the core rod assembly (10) during the blow molding process. At least a portion of the first fluid pathway (A1) may be longitudinally offset from the second fluid pathway (A2) so as to define respective first and second temperature zones (zone 1, zone 2) along the respective first and second portions of the core rod assembly (10).

An object of the present invention is to provide a blow molding device, a blow molding method, a mold unit, and a jig capable of shortening a molding cycle time. There is provided a blow molding device (100), in which the blow molding device (100) includes an injection molding part (10) injection-molding a preform (1) having a neck portion (3) on an open side and a main body portion (2) on a closed side, a temperature adjustment part (20, 520) adjusting a temperature of the preform (1) molded by the injection molding part (10), and a blow molding part (30) blow-molding the preform (1) whose temperature has been adjusted by the temperature adjustment part (20, 520), and the temperature adjustment part (20, 520) include a conditioning core mold (21, 321, 421, 521) that is in contact with substantially an entire inner surface of the main body portion (2) and a conditioning cavity mold (22, 322, 422, 522) that is in contact with substantially an entire outer surface of the main body portion (2), and compress and deform the main body portion (2) of the preform (1) into a desired shape with the main body portion (2) sandwiched between the conditioning core mold (21, 321, 421, 521) and the conditioning cavity mold (22, 322, 422, 522).

A core rod assembly (10) for blow molding includes a core rod head (16), a first fluid pathway (A1) extending along a first length of the core rod head (16), and a second fluid pathway (A2) extending along a second length of the core rod head (16). The first and second fluid pathways (A1, A2) may be fluidly isolated from each other and provide selective temperature control of respective first and second portions of the core rod assembly (10) during the blow molding process. At least a portion of the first fluid pathway (A1) may be longitudinally offset from the second fluid pathway (A2) so as to define respective first and second temperature zones (zone 1, zone 2) along the respective first and second portions of the core rod assembly (10).

A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.

A temperature adjustment device and a temperature adjustment method for a preform in a blow molding device with which it is possible to reduce a molding cycle time is provided. A temperature adjustment device for a preform in which a hollow rod member is inserted into an injection-molded, bottomed preform retained by a retention member, and a first air circulation path is formed between the preform and the hollow rod member to adjust the temperature of the preform. The temperature adjustment device is characterized in that a flow path adjustment member is fitted and attached to the outer periphery of the hollow rod member, whereby the cross-sectional area of the first air circulation path is partially adjusted and changed.

A blow molding device is provided in which a preform is injection-molded. The injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10° C. or more lower than the glass transition temperature of the preform.

In a manufacturing apparatus for manufacturing a resin container which includes an injection molding part configured to injection-mold a preform, a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part, and a blow molding part configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part, the preform is carried into the temperature adjustment part before an outer surface temperature of the preform molded in the injection molding part becomes higher than an inner surface temperature of the preform molded in the injection molding part, and the preform is cooled to be lowered within a range equal to or higher than 10° C. and equal to or lower than 50° C. in the temperature adjustment part.

A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.

The invention concerns a device for handling preforms for heating units. The device includes a mandrel that defines a rotation axis of the preforms; a tip mounted at an end of the mandrel and having a part penetrating into the neck of the preforms; a rubbing contact rigidly connected to the tip; and a heatsink rigidly connected to the mandrel and intended to come into contact with the tip. The tip also includes a cooling part axially in line with the penetrating part. The cooling part includes at least one thermal exchange raised portion in contact with the surrounding air. Furthermore, the tip is mounted such that it can be mobile on the mandrel.

A temperature adjustment part is configured to stretch a preform by moving a temperature adjustment rod toward a bottom surface portion (lower body portion) side of a body portion by a predetermined distance, after inserting the temperature adjustment rod into the preform to bring the temperature adjustment rod into contact with an inner surface of the body portion of the preform other than a boundary portion between the body portion and a neck portion.
