Abstract

The invention relates to the technical field of plastic packaging bottle anti-blooming processing, in particular to an anti-code-spraying anti-blooming plastic packaging bottle and a processing technology thereof. The processing technology sequentially comprises the following processing steps of burdening, injection molding, blow molding and demolding. In the injection molding step, the oil temperature of a bottle bottom mold area is higher than or equal to the oil temperature of a bottle shoulder mold area. By means of the processing technology, the plastic packaging bottle with the smooth bottle bottom can be obtained through processing. After the bottle bottom is subjected to code spraying, handwriting is clear and free of blooming. The bottom corner of the injection mold cavity of an injection mold is an arc-shaped corner, so that a microscopic groove is prevented from being formed in the bottom corner during blow molding, the bottom corner of a bottle blank obtained through injection molding is uniform in thickness, and the problem of frosted areas caused by the fact that a traditional bottom corner is a right angle is solved. Thus, the packaging bottle with the smooth bottle bottom can be obtained, and the problem of code spraying blooming of the bottle bottom is effectively solved.

Description

technical field [0001] The application relates to the technical field of anti-smudge processing of plastic packaging bottles, in particular to a plastic packaging bottle and its processing technology for anti-smearing of spray codes. Background technique [0002] Plastic packaging bottles can be widely used in pharmaceutical packaging, food and beverage packaging, cosmetic packaging, daily cleaning product packaging, and various chemical reagent packaging. Production date, shelf life, production batch number and other information. [0003] At present, plastic packaging bottles are mostly processed by one-step injection molding and blow molding. The injection mold includes an upper mold and a lower mold, and the upper mold and the lower mold are symmetrically arranged up and down. Such as figure 1 As shown, it is the lower mold of the injection mold, which has an injection mold cavity 11 in the shape of a semicircular barrel (determined according to the shape of the process...
