Description

Technical Field

[0001] This utility model relates to the field of electronic device component molding apparatus, and in particular to a mobile phone case molding apparatus. Background Technology

[0002] Phone cases serve to protect mobile phones. The types of phone cases designed and manufactured have become more diverse as the number of mobile phone brands and functions have increased. According to the material, there are leather, silicone, cloth, hard plastic, soft plastic, velvet and silk, etc. And according to the model, there are differences between candybar, flip and folding phones.

[0003] Taking folding phone cases as an example, in the production process of phone cases, a layer of leather is usually glued to the outer surface of a hard PC shell. After molding, the excess leather is removed by cutting, which is the core step that determines the product's dimensional accuracy and edge flatness. In the production process of folding phone cases, the phone case needs to be punched. The phone case to be processed needs to be placed on a contour block, and then punched by a punching device. In order to achieve a better punching effect, the phone case placed on the contour block is often pre-pressed before punching.

[0004] Existing pre-pressing devices are often set on the punching plate of the punching device. As the punching plate moves, the phone case sleeve on the conforming block can only be pre-pressed before punching. Since the placement of the phone case sleeve is mostly done by a robotic arm, it is easy to have placement deviations and it is not easy to place it in place in one go. If it is pre-pressed before punching, it is easy to cause deviations in the punching hole position and reduce the product qualification rate.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content
