A vertical injection molding machine should be checked when starting.

1. check for actuating oil: determine whether the vertical oil injection volume of the injection molding machine is between the lowest limit and the highest limit of the oil meter. The oil content of the automatic lubricator is suitable.

2. check for cooling water: make sure that the cooling water pipe system of vertical injection molding machine has no leakage phenomenon and adequate water volume, so as to maintain normal cooling effect.

3. temperature opening and checking: determine whether the heat of the dryer, pipe and die is normal, especially the temperature of the vertical injection molding machine must be completely reached the set temperature, and the action of shooting, releasing and hanging can be done.

4. inspection of safety door and safety guide rod: determine the opening and closing of the vertical injection molding machine safety door, and whether the contact between the safety door and the limit switch and the pressure relief valve is normal. Confirm whether the location of safety guide rod is proper and whether it is locked. The red emergency stop button on the front and rear operation box is normal, so as to ensure the safety of users.

5. check the lubrication device: whether the oil quantity of the butter mouth is sufficient, whether the time setting of the oil injector is proper or not, and whether the pipeline of the oil injection device is clear.

6. inspection of the active machine parts: all the active parts on the vertical injection molding machine need to be properly lubricated, and remove the impurities and dust from the active parts, keep the smooth and clean surface of the active friction surface, and do not put the tools on the active parts to prevent the damage when the machine is operated.

7. check for low pressure die closing device of vertical injection molding machine: correct the low pressure die closing device correctly, so as to ensure mould safety.

8., check other conditions: whether the temperature, pressure, speed, time and distance of various settings are appropriate.

9. inspection of the operation of the empty car: the low pressure can be fully automatic operation, so that the empty car runs about 10~30 minutes, and after a continuous stable condition, it can be formally operated.

10. examination of the sound of the sound: recording the normal operation sound and the sound of the oil pressure pump, it can detect the abnormal phenomena such as the filter blocking, the suction air, the internal wear and so on. The buzz of the solenoid valve is related to the impurities in the inner axis, and the buzz of the relay and the electromagnetic contactor shows that the dirt and dust exist between the contact points. . Checking the causes of abnormal sounds is a great help for prevention of injury.

Two, the vertical injection molding machine should be checked when shutting down.

1., close the material gate of the hopper, reduce or turn off the heating of the hopper (depending on the downtime). The plastic tube completely shot, especially the material is acidic and corrosive must implement the.

2., clean and wipe the mould of vertical injection molding machine and do rust treatment.

3., if the die is not unloaded, do not extend the curling hand.

4. turn off the cooling water and cut off the power supply.

5. vertical injection machine platform cleaning inspection and so on.
