Attention must be paid to the sudden abnormal noise of injection molding machine
If the injection molding machine makes noise during the processing and manufacturing of plastic products, it often represents that a part of the machine is having a problem, because a qualified injection molding machine will not make noise when working. Therefore, the operators must pay attention to the noise emitted by the injection molding machine and should not ignore it. The manufacturer of the injection molding machine reminds everyone that the noise of the injection molding machine should be checked first, so as to facilitate maintenance.
Reason 1: insufficient hydraulic oil. You should know that if there is not enough hydraulic oil in the oil tank of the injection molding machine, the oil pump is easy to absorb external air under working conditions, or it is easy to absorb some dirt to cause the blockage of the oil pump. This is tantamount to adding fuel to the fire, making the oil shortage more serious, and it will also make the bubbles in the oil have an impact on the blades, and the noise will naturally occur. How to solve this situation? We need to check the amount of injection molding oil to avoid the entry of air and dirt.
Reason 2: high viscosity. The viscosity referred to here is mainly hydraulic oil. If the viscosity of the hydraulic oil of the injection molding machine is high, the resistance in the flow process is also relatively large. Therefore, based on this situation, our staff need to detect it regularly and replace the hydraulic oil in time.
Reason 3: when the injection molding machine is working, if there is noise, it is likely to be caused by the damage of motor blades or the damage of oil pump bearings of injection molding machine. Under the influence of concentricity deviation, the noise will naturally occur. This requires the staff to check the concentricity or replace the parts of the injection molding machine.
The barrel, screw and check ring are important parts. If you want the machine to have good working efficiency and quality, you should keep the equipment in good working condition. Because it is an injection molding machine, it is necessary to avoid some debris from entering the material flow, and check the clearance between the barrel, check ring and screw. The clearance under normal conditions can play a shearing role. If there is a problem and it is not detected in time, or it is not handled in time, these important parts will be damaged.
