To do a good job in fault management and prevention of injection molding machines, it is necessary to understand the causes of injection molding machine faults, accumulate information and data on common and typical faults, conduct fault analysis, attach importance to the study of fault patterns and mechanisms, and strengthen daily maintenance, inspection, and pre repair. When there are some small problems with vertical injection molding machines in daily production, how should we check the vertical injection molding machine? Next, the editor will introduce it to everyone.
Take a look: mainly to check if there are any abnormalities in the plug and socket, whether the motor or pump operates normally, whether the control adjustment position is correct, whether there are signs of arcing or burning, whether the fuse is good or bad, whether there is liquid leakage, and whether the lubricating oil circuit is smooth. Are there any mistakes in these areas? If there are any problems in that link, please go and repair them in a timely manner.
Second touch: Touch the vertical injection molding machine with your hand to feel its vibration, the heat of components, the temperature of oil pipes, and the state of mechanical movement. Check if any abnormalities have occurred.
Three listening: Listen to the machine for any abnormal sounds during operation, and promptly eliminate and solve them.
Four Noses: Ask if there is any burnt odor, leaking odor, or other odor. Find out if there is a scorching odor or other conditions such as high temperature in that place.
Five checks: whether there are any differences in the shape and position of the workpiece compared to normal, whether there are any changes in the performance parameters of the injection molding machine, and whether there are abnormal circuit checks.
Conduct daily spot checks, patrol inspections, regular inspections (including accuracy checks), and integrity checks through human senses and general testing tools, with a focus on mastering the technical status and abnormal phenomena of easily malfunctioning parts, mechanisms, and components. At the same time, inspection standards should be established to determine the boundaries between normal, abnormal, and faulty injection molding machines.
The daily patrol inspection of workers and the status inspection of injection molding machines, as well as the obtained status information and fault symptoms, as well as relevant records and analysis data, will be arranged by the workshop injection molding machine repairman or repair team leader in a timely manner to address the problems of various types of vertical injection molding machines.
