Bottle injection, stretching and blowing all-in-one machine

Abstract

The invention relates to a bottle injection, stretching and blowing all-in-one machine. A core body of an existing injection and blowing all-in-one machine needs to be separated from a bottle blank, and the machining efficiency is affected. The bottle injection, stretching and blowing all-in-one machine comprises a rack, an injection molding mechanism, a bottle blowing mechanism and a conveying mechanism, wherein the conveying mechanism comprises a core body; an injection molding half is arranged at a cavity opening of an injection molding cavity; the core body downwards penetrates through the injection molding half and is inserted into the injection molding cavity to form a bottle blank through injection molding; the injection molding half is opened after driving the bottle blank to be upwards separated from the wall face of the injection molding cavity; and the core body carries the bottle blank to be separated from the injection molding cavity and the injection molding half and then moves into the bottle blowing cavity, so that the bottle blank is downwards stretched by the core body and blown into the bottle body. The core body does not need to be pulled out when the bottle blank is transferred, the ascending distance of the core body is shortened, the machining efficiency is improved by shortening the duration of single-time injection molding machining, the ascending height of the core body is reduced, excessive ascending space does not need to be reserved for the core body, then the height of the blowing and injection all-in-one machine is effectively reduced, deformation of the bottle blank is effectively prevented, and the use experience is improved.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to an injection stretch blow molding integrated machine. Background technique [0002] The existing injection-blowing integrated machine has the functions of preform injection molding and bottle body blowing at the same time, and can process granular raw materials into a bottle body in one step. Existing injection-blowing integrated machines include a frame and an injection molding mechanism, a bottle blowing mechanism and a transportation mechanism arranged on the frame. The injection molding mechanism is used for injection molding to form a preform. At the bottle blowing mechanism, the bottle blowing mechanism is used to blow the preform into a bottle body. The injection molding mechanism includes an injection molding cavity and an injection molding core that can be inserted in the injection molding cavity, and the bottle blowing mechanism includes a bottle blowing cavity and a ...

Problems solved by technology

[0003] When in use, the preform processed in the injection molding mechanism rises to the height of the cavity when the mold is opened, and then rises to the height of the preform itself. The preform is clamped by the Huff clamp and transferred horizontally to the blowing mechanism. It falls into the blowing cavity, and then the stretching mechanism is used to drive the stretching rod to insert the preform to stretch and blow the bottle, resulting in a long opening distance of the injection cavity and a large rising distance of the injection core, which will lead to a single injection of the injection mechanism. The required time will be longer due to the increase of the displacement distance of the injection core, and the height of the integrated machine will increase because the injection core needs a large space to rise, and it is necessary to set up stretching when the preform and the half clamp move to the blowing cavity. The sealing structure affects the production efficiency and increases the production cost. In addition, the Huff clamp transfers the preform by wrapping the mouth of the preform, and the body of the preform is easily deformed due to high temperature softening, resulting in Blowing mechanism processes deformed waste products, which affects product quality
