1, template parallelism template parallelism zui can reflect the condition of the clamping part, the template is not parallel will make the product unqualified and increase the wear of equipment and mold. The parallelism of the template can be initially reflected by the movement of the tail plate during the clamping and the appearance analysis of the product, but the exact situation needs to be detected by instruments such as a dial gauge. The adjustment of the parallelism of the template must be carried out by familiar personnel in accordance with the steps, otherwise the improper adjustment will cause more damage to the machine.
2, mold thickness adjustment should be used regularly to use the mold thickness adjustment system, the mold thickness from zui thick to zui thin back and forth to ensure smooth movement, for long-term production of the same mold machine, this must be done to avoid failure.
3. All mechanical activities of the central lubrication system require proper lubrication. The central lubrication system is one of the necessary injection molding machines. The amount of oil in the central lubrication system should be checked frequently to see if it is full. The lubricant used should be clean and free of impurities to ensure that all lubrication locations are supplied with lubricant. It is found that the tubing is blocked or leaked and should be replaced or repaired immediately. Most mechanical wear occurs due to lack of lubrication, so there is enough attention to lubrication.
4, to maintain the smooth movement of each movement or not smooth may be due to improper speed adjustment, speed changes and time uncoordinated or mechanical, oil pressure adjustment. This type of vibration will cause the mechanical part to accelerate wear and loosen the tightened screws, so vibration should be reduced and avoided.
5. Bearing inspection The bearing has a strange sound during operation, or the temperature rise indicates that the bearing has worn inside. It should be inspected or replaced in time, and re-injected grease.
6. Injection system The injection screw, the check ring and the barrel form the heart part of the injection molding machine, which determines the quality and efficiency of the processing and must be kept in good working condition. First, take the necessary measures to prevent non-plastic debris from mixing into the plastic stream. Also, pay attention to checking the correct clearance between the screw and the barrel, the check ring and the barrel. The normal gap should be able to seal the plastic backflow and produce plastic. For the shearing action required, the wear of the screw, the check ring and the barrel should be checked when it is found that the melt action is slow, the melt has spots and black spots, or the product is unstable.
