[0002] When the windshield of a car is installed on the sheet metal of the frame, a lower clip is set between the windshield and the sheet metal, which is used to achieve shock absorption, noise reduction and waterproofing. Therefore, a rationally structured lower clip is the key to ensuring the safe and stable installation of the windshield. The lower clip is completely bonded to the glass by double-sided adhesive, which requires a high bonding strength of the double-sided adhesive. The lower clip is formed by the internal aluminum strip glue coating to form a straight strip, and then the lower clip needs to be bent into an arc so that it fits the glass. The current bending molding mold requires multiple workers to pick up the lower clip, align the lower clip with the molding port and put it in. Before the bending molding mold is completely rolled into the lower clip, the unrolled lower clip must be kept in place.
