Injection molding machine operation points

    Before turning

    1. Before the injection molding machine operation, electrical control box to check whether there is water, oil into, if electrical damp, do not boot. Maintenance personnel should be dry before turning the electrical parts.

    2. Before the injection molding machine operation, check whether the supply voltage, generally should not exceed ± 6%.

    3. Check the emergency stop switch, the front and rear safety door switch is normal. Verify the rotation direction of the motor and pump are the same.

    4. Check the cooling pipe is long flow, the cooling water and the oil cooler and the barrel end of the cooling water through the jacket.

    5. Before the injection molding machine operation, check all moving parts if there is oil, and add a little oil.

    6. Open electric, for each segment barrel heating. When the temperature of each to meet the requirements, then holding for some time to stabilize the temperature of the machine. Holding time in accordance with the requirements of different devices and plastic raw materials vary.

    7. In the hopper enough to add a little plastic. The injection of different plastics requirements, some of the best raw materials to dried.

    8. To cover the heat shield on the barrel, so you can save energy, but also can extend the electric coil and contactor life.

    During operation

    1. Do not for the sake of convenience, free to cancel the role of the security gate.

    2. Observe the pressure oil temperature, oil temperature should not exceed the specified range. Hydraulic fluid over the operating temperature should be maintained at between 45-50 ℃, generally in the range of 35-60 ℃ appropriate.

    3. Note adjust the limit switch, to avoid the impact generated by the machine during operation.

    End of work

    1. After the injection molding machine operation is completed, it should clean plastic barrel to prevent oxidation or long-term residual material thermal decomposition.

    2. Mold should be opened to allow time toggle mechanism in a locked state.

    3. Workshop lifting equipment must be provided. Assembly and disassembly of mold should be very careful to ensure production safety.
