Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for automobile parts. Background Art

[0002] In the automotive manufacturing industry, stamping dies are indispensable tools for producing auto parts. They use specific shapes and structures to stamp metal materials into the required shapes of auto parts. Stamping dies are generally composed of punches and dies, which work together to complete the stamping of materials.

[0003] However, in the actual production process, due to the diversity and complexity of automotive parts, molds need to be replaced frequently to adapt to different production needs. The main problem of traditional mold fixing methods, such as screw fixing, is that the disassembly and assembly process is cumbersome. Every time the mold is replaced, the staff needs to spend a lot of time and energy to disassemble and install the screws, which not only reduces production efficiency, but also increases the labor intensity of the staff. In addition, loosening or damage of the screws may also lead to instability of the mold, thereby affecting production quality and safety. For this reason, we propose a stamping mold for automotive parts. Utility Model Content
