A blow molding device of the invention includes a pair of blow cavity split molds (A,B), a chuck member () that chucks a mouth portion () and conveys a preform (A), a blow core mold () that includes a tubular portion () which surrounds circumferences of the mouth portion and a flange () and introduces blow air into the preform, and a pair of projecting members (A,B) which have a halved ring shape and are provided detachably on each upper surface of the pair of blow cavity split molds. Each of the pair of projecting members includes an airtight sealing portion () which is in contact with a lower end face of the tubular portion of the blow core mold, and a positioning portion () which positions the flange of the preform.

Blow molding device, blow molding method, and preform sealing/positioning part

A preform has a flange that protrudes outward at a neck, and is supplied in an inverted state. A preform handling device includes a star wheel that is configured so that the preform is supplied to each of a plurality of depressions that are formed in an outer circumferential part of a wheel, and pushes the preform to rotationally transfer the preform from an upstream region to a downstream region, an end face guide member that is provided in the upstream region so as to be situated under the preform and that support and guide an open end face of the preform, and a pair of flange guide members that are provided in the downstream region and that support and guide a lower side of the flange of the preform.

Preform handling device, and blow forming device

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 Pto a second pitch P(P&#x3e;P), and an inversion section that includes N inversion arms that respectively invert the N preforms from the inverted state to the upright state.

Blow molding device and blow molding method

An injection blow molding system includes an injection molding station ( ), a first delivery section ( ), a cooling station ( ), a heating station ( ), a second delivery section ( ) and a plurality of blow molding stations ( ). The station ( ) simultaneously injection molds M rows of N preforms ( ) arranged in a second direction (B) perpendicular to a first direction (A) in which the preforms ( ) are carried. The first delivery section ( ) removes the M rows of preforms ( ) using a removing mechanism ( ) in their upright state while decreasing the pitch in the rows. The preforms are inverted with the column pitch changed by an inverting mechanism ( ) before delivery to the cooling station in their inverted state. The cooling and heating stations ( ), ( ) cool and heat one row of N preforms ( ) while parallel carrying them along a first carrying chain ( ). The second delivery section ( ) delivers the preforms ( ) to two blow molding stations while in their inverted state. Each blow molding station ( ) stretch blow molds the N/2 preforms into containers at the same time.

System of injection blow molding and injection molding device

A heat-resistant container molding apparatus and method which are compact and inexpensive and can reliably increase the crystallinity, reduce the residual stress in a container filled with a hot content such as thermally sterilized fruit juice, and prevent a thermal deformation with improved container stability at a raised temperature. The apparatus has a receiving and removing unit for receiving primary moldings obtained by blow-molding preforms and for removing final products, a heat treatment section for heating the primary moldings by bringing the primary moldings into contact with the inner wall of a heat treatment mold while pressurizing the interior of the primary moldings within the heat treatment mold, a final molding section for blow molding intermittent moldings into final products within a final blow mold, and a rotary plate, neck support fixing plate and neck support member for conveying the moldings through the receiving and removing unit, heat treatment section and final molding section.

Method of molding heat-resistant containers

A heat blow molding apparatus includes a supply section,a heating station,a transfer section,and a blow molding station,all of which are disposed linearly in a direction A in which preforms,are carried. The supply section,supplies the preforms,each having a neck portion in their inverted state. The heating station,simultaneously heats the inverted preforms,while they are being carried parallel to each other. The transfer section,transfers the inverted preforms,after they have been heated by the heating station. The blow molding station,simultaneously blow molds the inverted preforms,transferred from the transfer section,into containers.
