Common faults and troubleshooting of fully automatic casting molding machines:
Due to the harsh working conditions of the fully automatic casting molding machine, it is inevitable that malfunctions may occur after continuous operation for a long time, such as abnormal noise, unstable movement, or even the machine stopping at a certain position and unable to continue cycling. Once these fault situations occur, the operator should pay high attention, carefully observe, determine the location of the fault and its possible cause, and promptly eliminate the fault to ensure normal production. For PLC controlled fully automatic casting molding machines, due to their rich self-diagnosis functions, namely fault detection and monitoring alarm functions, under normal circumstances, the alarm is related to the monitored part, making it easier to diagnose and handle. In short, once a fully automatic molding machine malfunctions, it is necessary for the operator or repairer to conduct a comprehensive analysis in a timely manner, find the cause, and eliminate it.
The common faults of the fully automatic casting molding machine are: ineffective action, no action, no pressure, action errors, etc. The key to troubleshooting these faults is to distinguish whether it belongs to electrical, hydraulic or mechanical faults. Mastering the structure and working principle of the fully automatic casting molding machine, as well as the input and output conditions related to each action, the working principle of the hydraulic system of the fully automatic molding machine, and the pressure and speed adjustment methods are the basis for troubleshooting. Any abnormal noise, loose fasteners, deformed parts, or abnormal displacement require timely inspection and repair.
In short, the faults of the fully automatic casting molding machine, in addition to system faults, are many occasional faults, and the reasons are also multifaceted, including valve faults, pump pressure faults, wear and aging of various sealing components, mechanical and electrical faults, etc. The solutions vary. The key lies in familiarizing oneself with the working principle of the machine, mastering the input and output related conditions of the action, making full use of computer-aided diagnosis, identifying the cause, and troubleshooting.
