AI Technical Summary

Technical Problem

In the existing airbag frame mesh insert molds, the oblique top fixing method causes the fixed mesh position to not be filled with plastic, resulting in the missing structure, and the multi-stage oblique top advance and retreat structure is complex and prone to failure, making it cumbersome and time-consuming to repair and replace spare parts.

Method used

The airbag frame mold with a pre-folded mesh elastic needle fixing structure is used to fix the mesh during mold closing and injection molding. It is connected and fixed in the thimble hole through a thimble spring. The thimble pin is fixed when the mold is closed. The mesh cloth overcomes the spring force during injection molding and shrinks into the pin hole, thus filling the plastic.

Benefits of technology

The complete fixation of the mesh and plastic filling are achieved, retaining the structural integrity of the airbag frame, avoiding the loss of product structure, and effectively shortening the production cycle of the airbag frame.

[0024] In this embodiment, the mesh cloth is fixed by using ejector pins 3 during the mold closing and injection molding process of the airbag frame mold, and the ejector pins 3 are connected and fixed in the ejector holes 5 through ejector springs 2.
