In the use of the process of injection mold
ing machine processing, we must pay attention to safety matters, vertical injection molding machine
manufacturers to share the following under safety operation items include what?
Injection molding machine boot before 1.
To check whether there is water, oil into the electric control box, if be affected with damp be affected with damp, do not switch on.
Shall have the maintenance personnel will be electrical parts dry again after boot.
Check whether the power supply voltage is in accordance with, the general should not exceed & plusmn;
Check the urgent stop switch, before and after the safety door switch is normal.

Check whether the cooling pipe long distance open, and the oil cooler and barrel end of the cooling jacket into the water.
Check the activity parts for lubricating oil, add the lubricating oil and.
Open the electric heating, heating tube paragraphs of the machine.
When the temperature of the paragraphs is achieved, and then heat preservation for a period of time, so that the machine temperature to stabilize.
Holding time according to the requirement of the different equipment and plastic raw materials.
Inside the hopper add sufficient enough plastic.
According to different requirements of plastic injection molding, some raw materials best first after drying.
To cover the barrel on the insulation plate, so that we can save power, and can extend the life of the electric heating circle and current contactor (
1 in the process of injection molding machine operation.
Not for convenience, cancel the exit at will.
Observe the pressure oil temperature, oil temperature is not beyond the prescribed scope.
Ideal working temperature of hydraulic oil in 45 - shall be maintained
35-50 ℃, average in
60 ℃ range is more appropriate.
Pay attention to adjust the travel switch, avoid machine in action during the impact.
At the end of the injection molding machine work 3.
Must be equipped with lifting equipment in the workshop.
Mould should be very careful when installation and to protect the production safety.
Before the downtime.
Should be clear plastic barrel inside, prevention of leftover material oxidation or long-term thermal decomposition.
Mould should be open, to toggle lever mechanism of time in the blocking state.
