What are the most easily neglected areas in the maintenance of injection mold

The maintenance procedures required for each injection molding position depend on different die cycle times. Here are some general principles that each mold user can use to ensure the efficient operation of mold components such as hot runner, heater, guide post and thimble in case of accidents


1.you see a hole if there is a warning of rust or damp phenomenon - if you are found near hot runner vent have rust or damp phenomenon, it means that the internal condensation or possible water pipe burst.Humidity can cause a fatal short circuit to the heater.This condensation is more likely if the machine is shut down at night or on weekends instead of running year-round.

2.remind operators don't put the gate in the hot mouth to "clean up" off - if the operator happened to see there was a piece of stainless steel in the mold runner, it might be shuikou component is actually a point. "Cleaning up" what seems to be an obstacle often ruins the hot air. Not to damage the hot mouth, please confirm before taking action under the tongue type of hot runner system, ensure that all operators are trained and able to identify their access to all of the different types of tongue

3.Slide fasteners - this should be done weekly for machines running year-round

4.Cross-check the resistance of the heater - you should have measured the resistance of the heater when you first started using it, and now it's time to measure and compare again. If the resistance is up or down by 10%, consider replacing the heater to ensure it doesn't break down at critical times during production. If the initial resistance value has never been measured, measure it once and use it as a reference for future inspection of the heater

5.Check for signs of wear between the guide post and guide sleeve - look for signs of scratches or scratches due to lack of lubrication. If the marks are new, you can also extend the life of the guide post and guide sleeve by adding more lubrication. If the wear and tear is serious, it is time to replace the new parts. Otherwise, the cavity and core may not fit well, resulting in different thickness of the cavity wall

6.Check the flow of water - connect a hose at the outlet of the waterway to allow water to pass through the hose and stay in the bucket. If the water is not clear or colored, it may rust, and if the water is not free, it means that somewhere is blocked. If you find these problems, drill through all the pipes again to keep them open (or take whatever method you use most often). Improving the plant's water treatment system will prevent future problems caused by rust and congestion.

7.Clean the thimble - over the course of a year, the thimble can become dirty due to gas buildup and membranous impurities. Zhenye injection recommended that every six to twelve months with the mold cleaning agent good cleaning. After cleaning, apply a layer of lubricant to the thimble to prevent abrasion or breakage.

8.See hot pot mouth radius area if there is a fracture - fracture by residual heat in the machine's mouth loose hardens when pieces of plastic injection molding forward from injection plastic cylinder clamping force caused by the component. The problem may also be that the center line is not aligned. Both possibilities should be considered when a fracture is found. If all the damage has been too serious to prevent petals shape leakage (mold users previously used a term refers to between the guide sleeve and hot mouth of the machine of plastic leak), you should replace gate set
