[0002] A necking mold is a mold specifically used for necking processing. It can reduce the diameter of the mouth of a pre-drawn cylindrical part or tubular part to form a product part of the required shape. Necking molds are widely used in the field of plastic processing, especially in the production and processing of large plastic parts. In the process of injection molding of plastic parts, necking molds can neck the injection molded parts to improve their appearance and quality. Necking molds are indispensable tools in necking processing, and their design and use are of great significance to ensuring product quality and improving production efficiency.
