To develop the good habit of injection molding machine operation to improve the service life of the machine and production safety is of great benefit.

 

One, prior to the start of:

 

(1) check the electrical control box whether there is water, oil into, if the electric moisture, do not boot. Should the repair personnel will appliance parts dry after the boot.
 

(2) check whether the power supply voltage compliance, generally should not exceed 15%.

 

(3) check the emergency stop switch, front and rear safety door switch is normal. The rotation direction of motor and pump are consistent verification.

 

(4) check the cooling pipe is smooth, and the cooling water jacket oil cooler and the barrel end of the cooling water is injected into the.

 

(5) check each activity is part of a lubricating oil (grease), and add the lubricating oil.

 

(6) open the electric heating, heating tube sections of machine. When the temperature of each section to meet the requirements, the thermal insulation for a period of time, in order to make the machine temperature stable. The heat preservation time according to different equipment and plastic raw material requirements and different.
 

(7) and foot enough plastic in the hopper. According to the different requirements of the injection molding of plastic raw materials, some of the best first after drying.

 

(8) to cover the barrel on the heat shield, which can save energy, and can extend the life of electric heating coil and contactor.

 

Two, in the process of operation:

 

(1) not for the sake of convenience, cancel the effect of the safety door.

 

(2) observe the pressure oil temperature, oil temperature should not exceed the limit. The ideal working temperature of hydraulic oil should be maintained at between 45~50 DEG C, generally in the 35~60 temperature range more appropriate.

 

(3) note that the adjustment of each travel limit switch, to avoid the impact of the machine in action.

 

Three, at the end of the work:

 

(1) down before, should be in the machine cylinder plastic clean, prevent the leftover material oxidation or long-term thermal decomposition.

 

(2) should be the mold opening, the long time is in the locked state of the toggle mechanism.

 

(3) the workshop must have lifting equipment. Be very careful disassembly mold and other heavy components, to ensure safety in production.
