Description

Technical Field

[0001] The utility model relates to the field of bottle blank processing, in particular to a bottle blank cooling device. Background Art

[0002] The preform is formed by filling the raw materials into the gun mold of the mold under specific temperature and pressure through injection molding, and is formed under the working conditions of the injection molding machine. After injection molding, it is a semi-finished intermediate product, and then blow molded into a terminal product. The terminal products include plastic bottles, oil barrels, cosmetic boxes, shampoo plastic bottles, spray bottles and other packaging containers, which are essential products for people's daily life. The preform mouth needs to be cooled during the production process, so a preform mouth cooling device is needed. However, the existing preform mouth cooling device may cause the preform to tip over due to too much water sprayed during use, thereby affecting the production of the preform, so a preform mouth cooling device is indispensable.

[0003] The current bottle blank demoulding device has a particularly prominent problem in temperature control during demoulding operation. Due to the lack of effective rapid cooling means, the bottle blank often needs a long time to naturally cool to a temperature range suitable for subsequent processing after leaving the mold. The slow cooling process can easily cause the bottle blank to deform, such as bending, local depression or bulge on the bottle body, which seriously damages the dimensional accuracy and appearance integrity of the bottle blank. At the same time, due to the uneven cooling rate, a stress concentration area will be formed inside the bottle blank, which not only weakens the mechanical properties of the bottle blank, making it more prone to rupture and damage during subsequent transportation, storage or further processing, but also reduces the product yield and increases the scrap rate and production cost. To this end, we propose a bottle blank cooling device to solve the above problems. Utility Model Content
