Abstract

This article explores the influential factors leading to the failure of hot stamping molds and highlights the significance of mold maintenance. With the increasing production of electric vehicles and the adoption of lightweighting technologies, high-strength steel hot stamping forming has emerged as a pivotal approach in automotive lightweighting, underscoring the criticality of hot stamping molds. This article analyzes the hot stamping process, mold working conditions, and various factors that impact the lifespan of molds. During operation, hot stamping molds are subjected to cyclic thermal loads and stress concentration, which may result in wear, galling, cracking, honeycomb lines (micro-pits), and fracture. The failure and lifespan of molds are influenced by multiple factors, including mold design, material selection, heat treatment, manufacturing processes, surface treatment, and production processes. Proper mold maintenance plays a vital role in prolonging the lifespan of molds, ensuring part quality, controlling production costs, and mitigating the risk of accidents. The article discusses different levels of maintenance work, such as specialized maintenance, routine maintenance, and periodic maintenance, and underscores the importance of regular record-keeping, inspection, and evaluation of mold conditions. By implementing scientific management of maintenance work, the objectives of extending mold lifespan, enhancing production efficiency, and ensuring product quality stability can be achieved, thereby fostering the sustainable development of enterprises.
