1. What is the clearance between the guide post and the guide sleeve, whether there are burns or wear marks, and whether the oil supply state of the mold guide is normal or not, it should be checked.
2. The wear of the guides and the destruction of precision reduce the precision of the mold, and various parts of the mold will have problems, which must be properly maintained and regularly replaced. Check the accuracy of the material guide. If the guide pin is worn out, it has lost the proper accuracy and function of the tape guide and must be replaced. Check the condition of the ejection spring and the ejector spring to see if it is broken or if it has not been broken after long-term use, it has been fatigued and has lost its original strength. Regular maintenance and replacement must be carried out, otherwise it will cause damage to the mold or unsmooth production.
