Description

Technical Field

[0001] This utility model relates to the field of hot stamping die inspection technology, and in particular to a device for auxiliary thermal imaging inspection of hot and cold water injection of hot stamping dies. Background Technology

[0002] In the production of hot stamping dies, the cooling effect of the die inserts plays a decisive role in product quality and production efficiency. Controlling the die temperature by injecting cold and hot water into the water system and simulating the cooling process of the inserts during actual operation is an important means of optimizing die design and process parameters. However, existing simulation cooling methods still have many shortcomings.

[0003] Traditional cold and hot water injection systems cannot accurately simulate the cooling effect of inserts under different working conditions, making it difficult to truly reflect the heat transfer process of inserts and obtain the temperature distribution of inserts intuitively and comprehensively. Although thermal imaging detection technology can be used to detect temperature, existing devices have failed to effectively combine water injection simulation cooling with thermal imaging detection, resulting in the inability to quickly and accurately evaluate the cooling effect of inserts. This is not conducive to the optimization and improvement of molds and the adjustment of production processes, and it is difficult to meet the needs of high-precision and high-efficiency production of modern hot stamping molds.
