Injection molding machine mold parts maintenance, where to do

Date：2016-07-05 10:30:45

"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.
