AI Technical Summary
The arc-shaped die-cast shell has open mold deformation during the die-casting process, especially the thin-wall curved screen die-cast shell has a large deformation, which affects the product's contour and leads to tensile stress in the structural glue at the later bonding position, which affects the display effect and may cause serious consequences of opening the glue.
A stable contour structure of the die-cast shell on the vehicle curved screen is designed, including a fixed model cavity, a moving model cavity and a push rod pushing device. The tension is applied through the push rod reverse hook to prevent the arc-shaped die-cast shell from being pulled and warped during the mold opening process, and maintain the contour of the cast shell.
It effectively reduces the deformation of the die-cast shell, stabilizes the contour of the die-cast shell, improves the quality of the later product fitting and assembly, improves the competitiveness of the product, and avoids the gap between the arc-shaped die-cast shell and the screen.

[0002] With the development of science and technology, cars are becoming more and more intelligent. For consumers, cars are no longer just a means of transportation, but a carrier of entertainment life. In recent years, car companies have been tirelessly innovating screens. After experiencing floating central control screens and large-size vertical screens, dual screens known for their high-end and technological features have begun to appear in users' fields of vision. Dual screens refer to the integration of the instrument panel and the central control screen, which makes the interior more concise while also highlighting a sense of technology.
[0003] At present, the carrier of the dual screen is a curved die-cast shell. The deformation of the curved die-cast shell is a common problem. During the die-casting process, the curved die-cast shell has mold opening deformation, and the deformation of the thin-walled curved screen die-cast shell is even greater, which seriously affects the contour of the product. Later, during the bonding process of the die-cast shell and the screen, the gap between the die-cast shell and the glass screen is too large, and the structural adhesive at the bonding position has tensile stress, which affects the product display effect and sometimes causes serious consequences such as product debonding.
[0004] To this end, we propose a vehicle-mounted curved screen die-cast shell contour-stabilized structure. Utility Model Content
