1.Maintenance of common electrical system. Before driving, check the operation of the switch, trip switch, button control device has no failure; hydraulic pump maintenance, in the correct steering work available before move to check the motor and hydraulic pump; regularly check the power supply voltage is consistent with the electrical equipment voltage, voltage fluctuations should not exceed 10%; or regularly check the security door on the guide rail can slide freely touch travel limit switch, the switch should be sensitive to generate action; every time after shutdown, should choose switch to "manual" position, so when the next time you start causing accident; emergency stop button is set to avoid the occurrence of major accidents, therefore, the button is a sensitive is important, every day in the car should touch the button once, to see whether the normal operation; the various electrical components, to regular cleaning dust, tighten the screws, to see whether the observed contact with good contact, contact without burning phenomenon, whether the normal operation; if the injection molding machine long not to drive, the electrical system have to be periodically energized electrical components, in order to avoid damp.
  2.The part of the maintenance temperature. Plastic is made of molten plastic into the mold, the plastic melt is composed of electric heating to melting. Controlling the temperature by the temperature control device, which is mainly control the barrel heaters and nozzle heater. Maintenance of machine tube heater. Before driving, check the heater appearance, terminals, wiring and fastener is intact, the contact is reliable; turn on the power, check the thermocouple temperature sensor front end portion of the contact is intact and reliable; the fixed heating element must be reliable, especially with the power supply contact portion, if loose to make the fastening; with the current meter to check the thermal element current value, if not normal should be resolved in a timely manner; thermocouple and heater is supporting the use of, cannot be replaced individually replaced, and use the same name of commodity and specifications; the heater, the installation of the cylinder surface to be polished and clean, so that the heater and cylinder contact is good, after heating in general, fastening bolts are loose, so it should be fastened. Maintenance of nozzle heater. Layout periodically check the wiring and wire, wiring drawing part shall be free of plastic adhesion, lead can not be clamped; the position of the heater should be in the normal position, if it is found that the position change should be timely adjusted and fastening; regularly check the heater surface is not change the color of the spots, if it indicates a poor contact, should be timely to find out, keep good contact.
