Plastic bottle integrated blow molding equipment

Abstract

The invention discloses plastic bottle integrated blow molding equipment which comprises a mold assembly, a blow molding device and a cutting device. The mold assembly comprises multiple molds arranged side by side, telescopic hinges arranged at the bottoms of the multiple molds and a drive device used for driving the telescopic hinges to do telescopic motion. The telescopic hinges are formed by multiple X-shaped hinges arranged side by side, each X-shaped hinge is formed by two hinged rods with the middles being hinged through a hinged shaft, and the two hinged rods on each X-shaped hinge andthe two hinged rods on the X-shaped hinge adjacent to the X-shaped hinge are hinged to form telescopic structures. Each hinged shaft of each telescopic hinge is provided with one mold, each hinged shaft is connected to the bottom of the corresponding mold in an inserted manner, and the hinged shafts and the molds are in running fit. By means of the plastic bottle integrated blow molding equipment, plastic bottle production steps are shortened, and the plastic bottle production efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to an integrated blow molding equipment for plastic bottles. Background technique [0002] Plastic bottles are indispensable containers for pharmaceutical packaging and daily life. In the past, plastic bottles were generally produced by blow molding technology, that is, by means of gas pressure, the hot-melt parison closed in the mold is blown to form a hollow product. Blow molding is divided into extrusion blow molding and injection blow molding. [0003] Blow molding in the plastic bottle production line is mainly used to produce thin-walled hollow plastic products, such as water or soda water bottles, pipes, car bumpers and so on. Most thermoplastics include materials such as PET, PS, and PC that can be processed by blow molding, as well as glass. For the production of asymmetrical parts, extrusion blow molding is usually used. In the production line process, inj...

AI Technical Summary

Problems solved by technology

[0009] The existing production line has the following deficiencies: 1. The parison needs to be made first before the blow molding step, resulting in an increase in production steps and an increase in production line equipment costs. Bottle-shaped, no need to make parisons, so far no equipment for direct blow molding from plates has been found; 2. Before the blow molding process, the parisons need to be placed in the mold. In order to achieve this step, the mold must be The structure becomes complicated and the production efficiency becomes very low
