Patent ID: 8002539

Claim:
An injection stretch blow molding system with rotating and linear conveying functions, comprising: a lifting and rotating mechanism having a lifting seat able to ascend/descend on a machine body, a rotating plate is pivotally provided in the lifting seat, two bottleneck seats are oppositely and radially provided on the bottom surface of the rotating plate, each of the bottleneck seats has at least one bottleneck mold, with the rotation of the rotating plate, positions of the two bottleneck seats are able to be interchanged between a first and a second operating positions; an injecting mechanism installed at the first operating position and having a female mold installed below the rotating plate and at least one core mold installed on the lifting seat and able to be longitudinally moved, the core mold is able to pass through the rotating plate and the bottleneck mold of the bottleneck seat and enter the female mold, so a preform injecting operation is able to be proceeded; a conveying mechanism installed at the second operating position and having a conveying seat served to connect to the bottleneck seat rotated from the first operating position to the second operating position, each of the bottleneck molds clamps a preform, the conveying seat is driven by a convey driving device, so the conveying seat and the bottleneck seat connected to the conveying seat are moved towards an extending and blowing mechanism; an extending and blowing mechanism installed at a third operating position and having a bottle blowing mold controlled by an engaging driving device to open/engage molds, the preform is received in the bottle blowing mold and the top end thereof is provided adjacent to the bottleneck seat, an extending rod capable of lifting is installed on top of the bottle blowing mold and passes through the bottleneck mold of the bottleneck seat and enters the preform so an inflating operation is able to be processed; and a pushing mechanism installed at the second operating position and having a releasing device capable of lifting; after a bottle member being extended and blown is conveyed from the third operating position to the second operating position through the conveying mechanism, the releasing device is descended so that an mold opening operation is processed on the bottleneck seat and the bottle member is released from the bottleneck seat.
