Safe operation of injection molding machine!

    （1） Before starting the injection molding machine

    1. Check whether there is water and oil in the electrical control box. If the electrical appliance is damp, do not start it Maintenance personnel shall dry the electrical parts before starting the machine

    2. Check whether the power supply voltage is consistent, and the normal voltage shall not exceed ± 6%

    3. Check whether the emergency stop switch and the front and rear safety door switches are normal Verify whether the rotation direction of motor and oil pump is different

    4. Check whether all cooling pipes are unblocked for a long distance, and supply cooling water to the oil cooler and the cooling water jacket at the end of the barrel

    5. Check whether there is smooth oil at all moving parts and add enough smooth oil

    6. Turn on the electric heater and stop heating each section of the barrel When the temperature of each section reaches the request, it shall be kept warm for a period of time to stabilize the temperature of the machine The holding time varies according to the requirements of different equipment and plastic raw materials

    7. Add enough plastic into the hopper According to the requirements of injection molding of different plastics, some raw materials generally have to be dried first

    8. Cover the heat shield on the cylinder, which can save electric energy and prolong the service life of electric heating coil and current contactor

    （2） During the operation of injection molding machine

    1. Don't cancel the function of the safety door for convenience

    2. Pay attention to the temperature of pressure oil, and the oil temperature shall not exceed the regular range. The ideal working temperature of hydraulic oil should be 45-50 ℃, which is generally in the range of 35-60 ℃.

    3. Pay attention to adjusting each travel switch to prevent the machine from collision during operation.

    （3） When the injection molding machine is finished 3 The workshop must be equipped with lifting equipment. Be very careful when assembling and disassembling molds to ensure safe consumption.

    1. Before shutdown. The plastic in the barrel shall be cleaned to prevent residual material oxidation or long-term heating synthesis.

    2. Open the die to make the toggle mechanism locked for a long time.
