AI Technical Summary
During the molding process of the glass container, when the mold transfers the initial blank to the mold, the mold half opens to cause the opening to rotate, causing the initial blank to shift, which in turn causes the defect of the staggered suture of the primary mold and the mold forming suture of the glass container.
A limiting structure for the mouth mold of the glass bottle is designed, including the mouth ring body, the mold half body and the connecting seat. Through the sliding mechanism of the movable rod tail rod and the movable cavity, the connection between the fixed end and the connecting seat is ensured that the position of the mouth ring body is limited, thereby avoiding the rotation of the mouth ring.
It effectively avoids the rotation of the mouth ring when the mold half is opened, ensures the stability of the position of the initial blank, and prevents the defect of the staggered gap between the primary mold and the mold-formed suture of the glass container.
