Description

Technical Field

[0001] The utility model relates to the field of mold technology, in particular to a terminal piercing mold with low maintenance cost. Background Art

[0002] A mold is a tool used to shape a blank into a specific shape and size under the action of external forces. It is widely used in industrial production for blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of products such as engineering plastics, rubber, and ceramics. Simply put, a mold is a tool used to create a molded object. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the desired shape by changing the physical state of the molded material. It is often called the "mother of industry."

[0003] Stamping dies are essential equipment for producing a wide variety of industrial products. With the rapid development of the metal industry and the widespread application of metal products in sectors such as aviation, aerospace, electronics, machinery, shipbuilding, and automotive, stamping dies are widely used across various industries. Stamping dies involve several processes, including blanking, bending, and forming. The blanking structure within the stamping die is widely used by major connector mold manufacturers. In existing stamping structures, both the punch and the head are integrally constructed. Due to the width of the terminal, the multiple ends of the punch and the multiple ends of the head generally have narrow walls, resulting in weak strength and susceptibility to damage. Furthermore, since both the punch and the head are integrally constructed, damage to one end necessitates replacement of the entire punch or head, resulting in high maintenance costs and increased costs for the manufacturer. Therefore, improvements to the existing stamping structure are necessary. Utility Model Content
