AI Technical Summary

Technical Problem

During the production of battery boxes using molds, the small holes at the installation positions of the explosion-proof valves are prone to whitening, leading to product defects.

Method used

A secondary drilling mold structure is adopted, which includes an inclined guide post, a first slider assembly, a second slider assembly, and a snap-fit ​​base assembly. The inclined guide post drives the first slider assembly to slide, and combined with the constraint of the snap-fit ​​base assembly and the power of the spring, the secondary drilling of the explosion-proof valve installation position is realized, avoiding the phenomenon of tearing.

Benefits of technology

This improved the quality of battery box products during the mass production process of molds, reduced the whitening phenomenon at the explosion-proof valve installation position, and ensured the product qualification rate.
