Common faults and handling of injection molding machines (molding part)

Common faults and handling of injection molding machines (molding part)
(1): No mode-locking: Processing method: (1): Check the safety door front stroke switch and repair it. (2): Check the 24V5A battery in the electric box

Source, change insurance and power box. (3): Check if the spool is stuck and clean the valve plug. (4): Check if the I/O board has output, solenoid valve

Whether it is powered. (5): Check if the hydraulic safety switch is pressed and the mechanical lock lever is open.

(2): Opening and closing machine squealing: Treatment method: (1): Check if the lubricating oil pipe is disconnected. If it is, the oil pipe must be reconnected.

(2): The amount of lubricating oil is small, increase the amount of lubricating oil. It is recommended to use 50 mold oil once or manually add enough lubricant. (3): large clamping force, inspection

Check if the mold requires large clamping force and reduce the clamping force. (4): The current of the amplifier board is disordered, and the current parameters are checked to meet the acceptance criteria.

Newly adjust the current value. (5): Parallelism is out of tolerance, check whether the parallelism of the first two plates is greater than the acceptance standard with a dial indicator; adjust the parallelism.

(C): wait a few seconds before opening the mold: treatment: (1): slow start, to check whether the damper is too large screws, adjusting screws small orifice

. (2): The middle hole of the damping screw is too large. Check if the damping of the Y hole screw is too large, and change the damping pin of the center hole.

(4): Open the mold to crawl: Processing method: (1): The two-plate guide rail and the Corinth column wear large, check the two-plate guide rail and the Corinth column, replace the second

Copper plate, Colin column, filled with lubricating oil. (2): The pressure of the open mold is not properly adjusted, and the flow rate is set at 20. When the pressure is 99, the second mode is not clamped.

Should crawl, adjust the flow proportional valve hole, or pilot valve hole, adjust the linear current value of the proportional valve. (3): There is air in the pipes and cylinders.
(5): Open the mold to open: Processing method: (1): increase the speed of opening the mold, the pressure flow is too small, and the speed of the mold is checked.

Whether the pressure is appropriate, increase the pressure and speed of the open mold. (2): The clamping electronic scale is changed to zero position, and it is checked whether the clamping die straightening machine is terminated.

At zero position, readjust the electronic ruler zero. (3): Check if the hinge is reversed.
