[0002] The initial molding of glass mold is the preliminary molding process in the glass molding process. The glass mold used is generally a semicircular structure. In the process of the initial molding of glass mold, the glass mold needs to be placed on the mold groove and effectively fixed to prevent the initial mold from running off or shifting during use. After searching: Patent No. CN214571504U is a glass mold initial molding fixture, including a fixture platform and a mold groove arranged on the fixture platform, a fixed platform is arranged around the mold groove on the fixture platform, a plurality of slide rails and a slider matched on the slide rails are arranged on the fixed platform, and mutually matching push rods and push holes are respectively arranged on the slider and the mold groove, one end of the push rod is fixed on the slider, and the other end is matched in the push hole for fixing the glass mold initial molding, and both ends of the slider are provided with a connecting block and a set screw matched on the connecting block, and the set screw is used to fix the slider.

[0003] However, the above-mentioned clamp for the glass mold initial mold still has some shortcomings. Four elastic tension springs and clamping blocks are used to press down and fix the top four sides of the glass mold initial mold.
