Production process of zipper with diamonds

Abstract

The invention discloses a production process of a zipper with diamonds. The process is characterized by comprising the following steps that step 1, a zipper tape is enabled to pass through a space between a fixed upper die and a movable lower die; step 2, the diamonds are placed in a cavity in the upper surface of the movable lower die; step 3, the zipper tape moves forwards between the fixed upper die and the movable lower die and stops after moving to the injection molding position; step 4, the movable lower die is moved, the movable lower die and the fixed upper die form die assembly, the zipper tape is locked and fixed by the movable lower die and the fixed upper die, and the diamonds are pressed and fixed by the movable lower die and the zipper tape; step 5, glue feeding and injection molding are carried out; step 6, after injection molding is completed, a machine opens the die, and the movable lower die is separated from the fixed upper die; and step 7, the steps 2-6 are repeated. By adopting the scheme, the process is simple, the operation is convenient, the uniformity of the diamonds on each zipper tooth is ensured, the connection is firm and does not fall off, the appearance defects are few, the production quality is improved, meanwhile, the production of small-size zippers with the diamonds can be realized, and the problems that the existing small-size zippers with the diamonds are difficult to produce and cannot be produced in batches are solved.

Description

technical field [0001] The invention relates to the technical field of zipper manufacturing, in particular to a production process of a zipper with diamonds. Background technique [0002] Diamonds have high value and ornamental value. Many items are decorated with diamonds to enhance their beauty, but natural diamonds are rare and expensive, so artificial diamonds or imitation diamonds are often used to decorate clothing. Diamonds on zippers can improve the aesthetics of zippers. [0003] For example, a diamond-encrusted zipper disclosed in the Chinese utility model patent (CN 205390569 U) includes a pair of zipper tapes, the zipper tapes are provided with chain element rows, and the chain elements of the chain element rows are provided with inlaid pits. Decorative diamonds are fixedly inlaid in the mosaic pit, and the top surface of the decorative diamonds is a plane. The diamond decoration on the chain teeth has the advantages of simple structure, beautiful appearance and...

AI Technical Summary

Problems solved by technology

However, this kind of decorative diamond is simply pressed and embedded in the pit of the chain teeth. Not only is it easy to be knocked off during cleaning or friction, the connection between the drill and the zipper is not firm, and it is difficult to ensure the consistency of the diamonds on each chain tooth. Appearance, and affect its normal use function, especially for small zippers, the chain teeth are small, the diamond is small, the operation is more difficult, and it brings difficulties to its mass production
