AI Technical Summary
During the use of overmolding molds, the inner mold is difficult to position effectively, causing the injection liquid to deviate during flow and affecting the overmolding effect.
An inner-coated aluminum fixture positioning mold was designed. By setting movable buckles and slider structures on the aluminum fixture, the precise positioning of the inner mold during the injection molding process is ensured. The movable buckles fix the aluminum sheet, and the slider squeezes the aluminum sheet to prevent movement.
It achieves precise positioning of the inner mold, improves injection molding quality, optimizes the overmolding effect, reduces raw material waste, and increases production efficiency.
