Failure analysis and troubleshooting of injection molding machines2

Article source: Kexiang mold popularity:850 Publication time:2023-06-21 11:10:22

Medium-term injection molding machine fault analysis and troubleshooting: this type of method overall seems to be similar to the Chinese medicine "look, smell, ask, cut". The difference is that the injection molding machine is not intelligent enough to find faults without the need for human review, the location of the fault and the cause of the fault can be automatically reported to you. Therefore, the need for Dongguan Machiko injection mold factory technicians to be extraordinarily careful and meticulous, to troubleshooting. 


First, check the injection molding machine (including parts, components and wiring) 


1. Use the senses to check (this is a process of in-depth observation) 


① Look: whether there is any abnormality in the plug and socket; whether the motor or pump is running normally; whether the position of the control adjustment is correct, whether there is any arcing or burn marks, whether the fuse is good or bad, whether there is any leakage of liquid, whether the lubricating oil circuit is smooth, etc; 


② Touch: the vibration of the injection molding machine. Injection molding machine components of the heat, the temperature of the oil pipe, the state of mechanical movement is normal; 


③ Listen: whether there is any abnormal sound.

④Smell: whether there is any burnt smell, leakage smell, other strange smell (mostly the smell of burnt circuit or other strange smell); 


⑤Check: whether the shape and position of the workpiece have changed; changes in the performance parameters of the injection molding machine, and the inspection of circuit abnormalities. 


Second, assess the results of the inspection. 


Evaluate whether the fault judgment is correct, whether the fault clues are found, whether the results are consistent. In general, if a more skillful mechanic technician, the parameters of the machine and the machine's production products are more familiar with, so that you can independently to find the fault. If it is a new technician, you need to exhaust the conclusions and phenomena concluded by the record summary, confirmed by the relevant personnel to determine, so as to ensure that the real problem can be found.
