AI Technical Summary

Technical Problem

In existing connector product injection molding equipment, fittings are loaded into the mold by workers through manual assembly. Efficiency depends on the workers' skill level, which affects the continuity of the injection mold operation, resulting in a lot of wasted time during the injection process, reducing production line efficiency and increasing costs.

Method used

Design a quick-installation fixture for fittings, including a base, a fitting positioning structure, and an ejection structure. The fittings are precisely positioned by the fitting positioning boss and positioning pin, and the overall transfer and ejection are achieved by the ejection component and the fitting ejection pin, replacing the manual installation process one by one.

Benefits of technology

It enables rapid and stable loading and installation of fittings, improves the production continuity and overall efficiency of injection molding equipment, ensures product dimensional consistency and yield, and shortens mold waiting time.

Abstract

The invention relates to the technical field of hardware injection molding, and discloses a fitting quick-mounting jig which comprises a base, a fitting positioning structure and an ejection structure, the fitting positioning structure is mounted on the base and comprises a fitting positioning boss, and a first mounting groove and a second mounting groove which are used for placing fittings are formed in the fitting positioning boss; the ejection structure comprises an ejection assembly and a fitting push-out ejector pin, the ejection assembly is installed on the side, away from the fitting positioning structure, of the base, one end of the fitting push-out ejector pin is connected with the ejection assembly, and the other end of the fitting push-out ejector pin penetrates through the base and the fitting positioning boss to be suitable for making contact with a fitting. The fitting positioning structure further comprises a positioning pin, and the positioning pin is installed in the first installation groove and used for positioning the fitting. According to the structure, the production continuity and the comprehensive efficiency of the injection molding equipment are improved. The position precision of the hardware fitting in the jig and the final position precision of the hardware fitting in a mold cavity are guaranteed, the product size consistency is effectively improved, and the yield is increased.
