"Each injection mold required for injection molding machine annual
maintenance program position, depending on the mold cycle. Here are some
maintenance tips injection molding machine mold parts, allowing each
user to ensure that the injection molding machine hot runner mold,
heating effective runner, guide posts and thimble, molding inserts, such
as mold components to prevent accidents from happening.
1. Check whether the injection molding machine at the aeration holes have early warning of rust or damp phenomenon
If you find the hot runner near the discharge vent rust or damp
phenomenon, it means that internal condensation, or water may be broken
in the injection molding machine. Damp phenomenon will lead to a fatal
short circuit heater. If the injection molding machine is not running
endlessly throughout the year, we need to shut down in the evenings or
weekends, then the probability of occurrence of such condensation
increases.
2. Remember to alert the operator not to heat the nozzle head at the gate of the injection molding machine "clean" out
If the operator happen to see die at the outlet of a small piece of
stainless steel, there may be a point nozzle assembly. "Clean up" out of
this seemingly impeding things often ruin head hot mouth. In order not
to damage the injection molding machine hot mouth, please before taking
action to confirm the type of nozzle head hot runner system, and to
ensure that all operators are well trained and can identify different
types of mouth own head contact.
3. The injection molding machine sliding stop button
For the year endlessly running machine, this work should be done once a
week. And the end is a very good opportunity to give these parts a
routine lubrication and maintenance.
4. The resistance value of the cross-validation of the injection molding machine heater
You should start using the heater when it has been measuring its
resistance value, it is the end of the year again, when measured and
compared. If the resistance values are ± 10% of the float should
consider getting a replacement heater to ensure that it does not fail at
the critical moment of the production process. If it has never been
measured initial resistance value, so now measured once, and the
resulting value is used as a reference for future examination of the
data when the heater.
5. Check the injection molding machine and injection molding machine guide pin guide bush whether there are signs of wear
Looking for scratches or abrasions and other traces of mold parts that
wear due to lack of lubrication caused. If traces only just appear, you
can also give the injection molding machine and injection molding
machine guide pin guide sleeve plus lubricant to prolong its life. If
wear is very serious, it should be replaced with new parts up.
Otherwise, the cavity and core portions may not be a good fit, resulting
in different parts of the cavity wall Bohou.
6. Check the flow of water injection molding machine
Connect a hose in an injection molding machine at the exit of the
waterway, to let the water through the pipes to the bucket. If you do
not clear out of the water or the color, there might be rusty
phenomenon, which means that the water is not smooth blockage somewhere.
If you find that these issues will be drilled through all the pipes
again (or you take any of the methods most commonly used to clean up),
in order to ensure the smooth flow. Improved plant's water treatment
system that can prevent the emergence of various problems caused by the
rust and blocking future.
7. Clean the injection molding machine thimble
After a year's time, thimble and a film due to gas accumulation of
impurities becomes dirty. Mold cleaning agent recommended some good
cleaning every 6-12 months. Clean, and then coated with a layer of
lubricant on the thimble to prevent scratches or breakage.
8. Check whether the hot mouth radius fracture region
Fracture is left in the machine loose hot mouth hardened plastic debris
by clamping force from the cartridge assembly in the forward injection
caused. Cause of the problem is also possible that the centerline is not
aligned. When the fracture was found, to consider both possibilities.
If you have suffered damage severe enough to prevent leakage when the
petals (a term used by the previous user mold means between the thermal
head in the mouth of the guide sleeve and the emergence of machine
plastic leak), it should be replaced sprue bushing.
