Now is the hot summer with high temperature and rain, and it is also the period when machinery and equipment such as injection molding machines are most prone to failure.

       As a professional platform to solve the problem of after-sales maintenance of industrial equipment, recently, for the maintenance of Custom bucket injection molding machine for sale, several common faults have been summarized, and the corresponding treatment methods have been given.

　OEM all electric injection molding machine,Wholesale microplast injection molding machine for sale,Custom bucket injection molding machine for sale

　　1. After the injection molding machine motor is started, the pressure gauge has pressure

　　Approach:

　　1. The amplifying board is damaged, use a multimeter to test whether there is current passing through, and repair the amplifying board.​​

　　2. The overflow valve is stuck, remove the overflow valve for inspection, and clean the overflow valve.

　　2. After the Custom bucket injection molding machine for sale is started for a period of time, the oil pump makes a loud noise

　　Fault causes and solutions:

　　1. The quality of the oil suction pipe is not good: remove the filter screen to check whether it is deformed. Whether the oil suction pipe is layered. Replace oil pipe and filter.

　　2. The filter screen is not clean: whether there are too many impurities in the hydraulic oil. Clean the filter.

　　3. Oil pump wear: Check the oil pump oil distribution plate and rotor end face. Replace oil pump.

　　3. Wholesale microplast injection molding machine for sale crawls

　　Fault causes and solutions:

　　1. Poor lubrication conditions, "pause-glide-pause": increase the amount of lubrication.

　　2. The system is immersed in air: exhaust is required.

　　3. Due to mechanical rigidity, parts are worn and deformed, causing changes in friction and crawling: replace parts.

　　Fourth, OEM all electric injection molding machine hydraulic oil pollution

　　Cause Analysis

　　1. Air is mixed in the oil: the main feast is not well sealed due to pipe joints, hydraulic pumps, hydraulic cylinders, etc. It is manifested in the presence of air bubbles on the fuel tank.

　　2. Water mixed with oil: it will turn the oil into milky white. Main dinner cause cooler leaking.

　　3. Solid impurities mixed in the oil: mainly chips, welding slag, rust flakes and metal powder.

　　4. Glue-like substances are produced in the oil: the main feast is that the seals are eroded by the oil or the oil is deteriorated, resulting in the production of jelly-like substances in the oil, which often block the small holes.

　　5. The sound of the injection molding machine is loud when the mold is opened

　　Troubleshooting method:

　　1. The proportional linearity is poor, the time position of mold opening and closing is not well adjusted, check the ramp up and down of the amplifying board, adjust the ramp up and down of the amplifying board, and adjust the time appropriately.

　　2. The clamping machine hinge is poorly lubricated, check the Collin column, the second plate sliding foot, and the lubrication of the machine hinge, and increase the lubrication.

　　3. The clamping force of the mold is too large, check the clamping force when the mold is stressed, and reduce the clamping force according to the user's product.

　　4. The deviation of the parallelism of the head and the second plate, check the parallelism of the head and the second plate. Adjust the parallel error of the second board and the head board.

　　5. Slow rotation and fast mold opening position is too small and the speed is too fast. Check whether the position of slow mold opening to fast mold opening is appropriate, and whether the slow mold opening speed is too fast. Lengthen the slow mold opening position and reduce the slow mold opening speed.
