The thimble cannot be returned to the position.3，The temperature of injection molding is too low.The fully automatic action is out of order1，Failure of the electric eye, loose fixation screw or poor light concentration.8，Check whether the position, speed and pressure of the locking mould are adjusted normally. Insufficient water transportation, so that the temperature is too high, which prevents the colloidal particles of enering the screw.
The mode-locked electromagnetic coil may have moved into the valve and become stuck to the core.Semi-automatic failure: semi-automatic cycle, is by the mechanical action, touch the electric switch system andtime, an electrical signal, the control system of oil, if in manual mode, every movement is normal, and semiautomatic failure, the most is due to the time of electric switch system and the system has not issued a signal, thefirst observation of semi-automatic action is in the stage of failure, contrast "motion cycle chart" to find out thecorresponding control element, and resolved to check.2，Failure or damage of time system.
Thermometer damaged.Adjust the injection pressure.3，Insufficient pressure oil. If not,check whether the corresponding output transistor or relay is damaged. There is no material in the hopper. Check whether the electric hot air switch to the electric box is switched on, whether the contractor and relay are closed, whether there is voltage, whether the insurance is burnt out, whether the heating coil is burnt out. If the temperature can't be raised by adjusting the thermometer, check whether the electric heating tube and fuse are burnt out or loosened.4，Repair the cooling system due to water shortage caused by a fault in the cooling system.
Check whether the oil valve cored is in normal operation. Check whether the contact point of the electric thermal contractor is sticky, whether the wire of the thermocouple is loose or damaged.Adjust or replace the back pressure valve of sol.5，Press the launcher buttoned to check whether the computer screened displays the signal in front of thelauncher, or other signals and alarms.3.Repair or replace the oil pump.Adjust the water transportation and take out the adhesive blocks.7，Press the lock mode key to see whether the display screen displays the lock mode signal or other signals and alarms.4，Loose connection or poor contact of injector combination open valve.2，Impurities plug the proportional pressure valve oil port of the oil pump.3,Check the forward speed of the fir platform and check whether the pressure is improperly adjusted.2，The temperature cannot be increased.The opening makes a sound1，The open-die traveled switch system does not have card or card system failure.The sol-screw turns, but the glue does not enter the barrel1.2.Adjust or replace time system.4，Check the 1/0 plate, and check whether the voltage (DC+24V) output by the directional valve are normal.Feeding.2，Oil pump damage and low pressure oil concentration.5，Oil injection barrel, oil throats and joint leakage.Replaced.The pressure oil is too hot1，The pressure of oil pump is too high.Eliminate leakage area.Adjust or replace the solenoid valve.The temperature of the glue tube can’t be controlled1，The temperature cannot be controlled.Clean or replace the solenoid valve.Adjusted.3，Direction valve may not be in position.The hexad doesn't move1，The moving limit stroke switch to the ejection platform is adjusted and the collision block is pressed.Remove the proportional pressure valve to remove impurities.Adjust the thermometer to raise the temperature to the required point. The back pressure on sol is too high, and the back pressure # valve is damaged or improperly adjusted.Check whether proportional pressure valve is energized.So as to restore the electric eye.2，The fixing screw of the slow-speed solenoid valve is loosened, or the valve core is stuck.Clean the filter oil and replace the pressure device. The melt tube is too hot.Fastening or replacement.Cleaning or replacing the mode-locked open-die control valve.Clean direction valve.1，The solenoid coil may be burnt, or something outside may enter the directional valve and move with the valve core.3，Is the thermometer damaged?No clamping1，Whether the front opening safety door has been closed, whether the limit device of the safety door has been pressed and loosened, and whether the wiring has been loosened or damaged.It should be adjusted to the demand pressure of glue material.5，Check whether the origin of the computer controller's locking module and opening module has been changed, and whether the position of locking module has been terminated.3，The heating tube is damage.Increasing pressure oil.Adjusted to a significantly slow speed.6，Check whether the pressure gauge is in action.3，The pressure oil is unclean, and debris accumulates on the filter surface to prevent the pressure oil from entering the pump.6，Check whether the pressure gauge is in action.4，Oil leakage of the oil pump, damage caused by excessive use, internal loss or dirty pressure oil.Check whether the thimble is acting normally. See if the conveyor is blocked or uncool.2，Too low pressure.9，Check whether the piston rod of the locking mould is broken..1，Loose connection to proportional valve on oil pump or burnt coil.Properly connect the combined switch line head.2020When we encounter the common failure of injections molding machines,we should do:Pump motor and pump start up, but no pressure.Check oil pump and oil quality.2，The coil of the ejector moving solenoid valve may be burnt or something outside may enter the directional valveand move with the valve core stuck.4，Improper or damaged connection of thermocouple.6，Oil business card printing is dead.Clean or replace the solenoid valve
