Вопросы-Ответы
Injection moulding machine can’t clamp:

Handling method:

1) check the front travel switch of safety door and repair it.

2) check the 24V5A power in the electric box, replace the insurance and the power box.

3): check whether the spool is stuck, clean the spool.

4): check the I/O board has output or not,weather the magnetic valve is open or not.

5): check whether the hydraulic safety switch is closed, whether the mechanical lock rod is opened or not.

The noise of mold open and closing:

Handling method:

1)check whether the lubricating oil pipe is cut off , if so, reconnect the tubing pipe.

2): small amount of lubricating oil, increase lubricating oil amount , add once at 50 mold open-close circle,or manually add lubricating oil.

3): clamping force over large, check whether the mold needs large clamping force, lower the clamping force.

4): the current fluctuation of the amplifier board, check whether the current parameters meet the acceptance criteria, re adjust the current value.

5): parallelism error,use  indicator to check head board parallelism to make sure it’s  greater than the acceptance criteria or not; adjust the parallelism.

Mold open-closing scramble:

Processing method:

1): the second plate and the tie bar are worn out, check the second plate and tie bar, replace the second copper sleeve, tie bar, add the lubricating oil.

2): the speed of mold open -close and pressure adjustment is not correct, set flow 20, pressure 99, the second platen should not crawl, adjust the flow proportional  valve hole, or open valve hole, adjust the proportional valve linear current value.

3) air in pipes and tanks,exhaust it.

wait a few seconds to open the mold:

Handling method:

 1): starting speed is slow, check the screw damping ,wheher it is too big, adjust to use  screw with small damping hole.

2): damping screw middle hole too big, check the Y screw hole damping is too large or not,change for damping nail with smaller center hole  .

Can’t open the mold:

Processing method:

1): increase the speed of the mold open-close, the pressure and flow is too small, not adjusted, check the speed of the mold open-close, the pressure is appropriate or not, increase the pressure and speed of the mold open-close.

2): The electronic ruler in clamping unite is zero change, check the ruler,whether it is stop in the zero position or not, re adjust the electronic ruler into zero position.

3) check whether it is anti- hinge.
