Description

TECHNICAL FIELD

[0001] The utility model relates to a demoulding device technical field, concretely is a kind of plastic sunscreen bottle processing quick demoulding device. BACKGROUND

[0002] Plastic sunscreen bottle is a kind of container for storing and dispensing sunscreen, usually made of polyethylene (PE), polypropylene (PP) or polyethylene terephthalate (PET) plastic materials. These materials have good chemical resistance, weather resistance and transparency, which can protect sunscreen from light, oxygen and microorganisms. Blow molding is a common technique in plastic bottle production, which uses gas pressure to blow the hot melt blank closed in the mold to form a hollow product. The process generally includes the following steps: the blank is installed in the nozzle of the machine, then placed in the mold, the mold is divided into two halves, hot air passes through the blow head to expand the shape of the mold, and the blank is cooled in the mold for a few seconds, and then demolded.

[0003] However, the traditional plastic bottle processing quick demoulding device has the following problems: the two clamping blocks on the nozzle are driven by the driving mechanism to limit and fix the top end of the blank. After the nozzle blows the blank, the two clamping blocks are controlled to separate from the blank port, and the plastic bottle falls under its own weight to demold. The nozzle of the machine is located outside the mold and communicates with the inner cavity of the blank. The blank in the mold is formed after blow molding, but the part of the blank outside the mold connected with the nozzle cannot be formed. The traditional demolding device has single function and cannot cut the unformed blank connected to the port of the formed plastic bottle. Additional equipment is needed for subsequent cutting and processing, which is complex and leads to poor demolding effect and low plastic bottle production efficiency. Therefore, we propose a plastic sunscreen bottle processing quick demoulding device. Utility model content
