AI Technical Summary
In the existing technology, the positioning of hardware parts on the car body is unstable, which leads to molding problems. In addition, the protrusion height of the hardware parts cannot be too high, resulting in the positioning groove depth being too shallow to meet the molding requirements.
The system employs a combination structure of movable insert, ejector sleeve, and spring. The movable insert is mounted vertically on the second mold core, and the ejector sleeve passes through the through hole in the movable insert. The spring increases the depth of the positioning groove in the mold-opening state to ensure stable positioning of the hardware. In the mold-closed state, the depth of the positioning groove decreases to meet the molding requirements.
It achieves stable positioning and forming requirements for hardware parts, avoids molding problems, and ensures a firm connection of hardware parts to the car body.
