Boot before

1. Before the operation of the injection molding machine, check whether there is water or oil in the electrical control box. Maintenance personnel shall blow dry the electrical parts before starting the machine.

2. Before the operation of the injection molding machine, check whether the supply voltage is in line with the general should not exceed 6%.

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

4. Check whether the cooling pipes are unblocked for a long distance, and connect the cooling water jacket of the oil cooler and the end of the machine barrel into the cooling water.

5. Before the operation of the injection molding machine, check whether there is lubricating oil in the moving parts and add enough lubricating oil.

6. Turn on the electric heating and heat each section of the barrel. When the temperature of each section reaches the requirement, keep the temperature of the machine stable for a period of time. The holding time varies according to the requirements of different equipment and plastic materials.

7. Put enough plastic in the hopper. According to the requirements of different plastic injection molding, some raw materials had better be dried first.

8. Cover the heat shield on the barrel, which can save energy and extend the life of the electric heating coil and current contactor [1].

The operation process

1. Do not covet convenient, cancel the action of safety door at will.

2. Pay attention to the temperature of pressure oil, oil temperature do not exceed the specified range. Ideal working temperature of hydraulic oil should be kept between 45 to 50 ℃, average within 35 to 60 ℃ is more appropriate.

3. Pay attention to adjust the stroke switch to avoid the impact of the machine in action.

End of the work

1. After the operation of the injection molding machine, the plastic inside the barrel should be cleaned to prevent oxidation of residual materials or long-term thermal decomposition.

2. The mold should be opened so that the toggle mechanism is locked for a long time.

3. The workshop must be equipped with lifting equipment. Care should be taken when assembling and disassembling molds to ensure production safety.
