Automotive aluminum casting mold trial run is a high-risk link before mass production, involving high-temperature molten aluminum, mechanical clamping and pressure operation, and must comply with unified industry safety standards to avoid equipment damage and personal safety accidents. The complete mold trial safety system includes 8 core standardized procedures covering pre-trial detection, parameter setting, operation control and real-time monitoring. Pre-trial static pressure test with 0.6MPa holding pressure for 20 minutes can fully detect hidden defects such as mold structural gaps, sealing failures and pipeline leakage, realizing 100% screening of structural hidden dangers. Gradient temperature preheating is adopted instead of constant temperature rapid preheating, heating from 80℃ to 200℃ step by step, which eliminates instantaneous thermal stress and reduces thermal crack risk during trial run by 93%. The first three trial castings adopt 30% rated low-speed filling to avoid strong impact of high-speed molten aluminum on the new mold cavity, reducing mold impact deformation risk by 87%. Before trial production, professional clamping force calibration is carried out to ensure the force matches 1.2 times the casting pressure, completely eliminating mold opening and flash faults. In the whole trial run process, real-time monitoring of mold temperature, water flow, casting pressure and filling speed is implemented, with automatic early warning for parameter deviation, reducing safety accident rate to below 1.5%. All trial run operators must hold professional certificates and implement one-person monitoring and one-person operation mechanism to ensure full-process safety control.
