Description

Technical Field

[0001] This utility model relates to the field of die casting technology, specifically to a die casting device for the middle suspension beam of a folding screen. Background Technology

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. Traditional die casting mainly consists of four steps: mold preparation, filling, injection, and sand removal. These steps form the basis of various improved die casting processes. Most die-cast parts are iron-free, containing materials such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Die casting molds are typically made from higher-strength alloys. Outdoor screens, or outdoor displays, usually consist of multiple components. With changing user needs, foldable outdoor displays have emerged for easier transportation and installation, involving various connecting components. The central suspension beam is a crucial connecting component for foldable screens, featuring a hollow structure with several connecting holes and protruding connecting parts on the sides. Openings are also present on opposite sides (e.g., Figure 8 As shown in the figure, machining would be very time-consuming, so die casting is required for production. Therefore, a corresponding molding device needs to be developed for the middle suspension beam of the foldable screen. Utility Model Content
