This utility model provides a deep cavity injection mold for a plastic storage box, belonging to the field of injection molding. It includes a moving mold plate and a fixed mold plate. The moving mold plate contains a core, and during mold closing, a box forming cavity is formed between the moving mold plate, the core, and the fixed mold plate. The core has several box edge forming strips on both sides, each located within the fixed mold plate. These strips extend into the box forming cavity, and adjacent strips form box edge forming grooves. The box edge forming strips are connected to a demolding drive structure located within the fixed mold plate. Since the plastic part is a deep cavity storage box, traditional straight-ejector or angled-ejector ejection methods can easily cause the part to break. Therefore, the demolding drive structure located within the fixed mold plate replaces the traditional straight-ejector or angled-ejector ejection method, making the plastic part less prone to deformation during demolding and improving product yield.
