If a machine is to be used for a long time, it is indispensable to use regular maintenance. No matter how good the quality, the machine needs frequent maintenance to have a longer service life, so let’s talk about the maintenance of the molding machine. Repair method.

First of all, the circuit: pay attention to cleaning the circuit board, regularly clean up the dust on the strong and weak electrical boxes, keep the electrical boxes dry, and prevent moisture.

The second is the oil circuit: check for oil leakage in various parts of the oil circuit, and deal with it in time. Prevent the piston rod from scratching and oil deterioration.

Finally, machinery: check whether the transmission part of the machine is worn or not, check whether each grease nipple is blocked, and inject grease.

Other precautions: It is recommended to replace the hydraulic oil once a year and clean the oil sludge in the oil tank. The water cooler should be cleaned in time to prevent the oil temperature from rising and accelerating the aging of the oil. Of course, safety is no small matter. The circuit safety door switch, the oil circuit pressure relief valve, and the mechanical safety stopper , When the machine warning light is maintained, it must be checked whether it is working properly.

Daily maintenance:

① Check each lubrication point in the equipment every day before taking over to see if the lubricating oil (grease) is sufficient, and add lubricating oil (grease) if necessary.

② Listen to whether there is any abnormal sound from the operating equipment. If the operating sound is abnormal, you should contact the relevant personnel if necessary, and decide whether to shut down for maintenance according to the situation and eliminate the fault.

③ Check whether the temperature control and instrument display of each process are normal. If there is any abnormal phenomenon, check whether the heating device and temperature control system are working normally. If necessary, ask the relevant personnel to check and repair.

④ After taking over, first check whether the positions of the working switches and buttons are correct, whether the limit switches are loose, and whether the safety door works flexibly and accurately to ensure production safety.

⑤ Before starting the first train to feed materials into the hopper, first check whether the hopper is clean and remove all debris in and on the hopper.

⑥ Note that the screw dry running time is not allowed to exceed 3 minutes, except for the trial run before production, the screw is not allowed to run dry at ordinary times.
