Abstract

The present invention relates to the technical field of moulding devices for manufacturing infusion bottles, and particularly to an integrated moulding device for manufacturing bottles. After bottle blanks are injection moulded by a bottle blank injection moulding device, the bottle blanks moulded by one mould are clamped at one time and mounted on neatly arranged bottle blank clamp heads by a manipulator arranged between the bottle blank injection moulding device and a bottle blank transportation device. A drive belt transports the bottle blank clamp heads in the direction of a front-end baffle plate in the process of operation. A front-end opening, which only allows a single bottle blank to pass through, is arranged in a middle part of the front-end baffle plate. Therefore, the bottle blank clamp heads pass through the front-end baffle plate one by one, then enter a front-end transportation track and are correspondingly subject to the processes of welding rings, heating, blowing bottles and the like. After the bottle blanks are de-moulded, the bottle blanks from the entire mould are arranged on the bottle blank clamp heads and are mutually separated from one another, thereby not only accelerating the cooling speed, but also enabling cooling to be more even. Once the bottle blanks are de-moulded, the bottle blanks are arranged on the bottle blank clamp heads, thereby avoiding the pollution to inner cavities since outside air comes into contact with the inner cavities of the bottle blanks for a long time.
