Injection molding machine is one of the commonly used equipment in the plastic processing industry, to do a good job in the fault management and prevention of injection molding machine, we must grasp the causes of injection molding machine failure, accumulate data and data of frequent failures and typical failures, carry out failure analysis, pay attention to the study of failure laws and failure mechanisms, and strengthen daily maintenance, inspection and pre-repair. So what are the preventive measures to reduce injection molding machine failures?
1. Do a good job in publicity and education, so that operators and maintenance workers consciously record, count and analyze the faults of injection molding machines, and put forward reasonable suggestions.
2. Closely combine the actual injection molding production and the characteristics of the injection molding machine, and divide the injection molding machine into three categories: A, B and C, so as to determine the focus of fault management.
3. Use monitoring instruments to monitor the key parts of the key injection molding machine in a planned manner, and find the signs of failure and deterioration information in time. Generally, the injection molding machine should also carry out daily spot checks, patrol inspections, regular inspections (including accuracy inspections), intact state inspections, etc., through human senses and general testing tools, focusing on mastering the technical status and abnormal phenomena of parts that are prone to failure. At the same time, it is necessary to formulate inspection standards to determine the boundaries of normal, abnormal and faulty injection molding machines.
4. Carry out failure analysis and train injection molding machine maintenance workers to master failure analysis methods.
5. Fault record is the basic data for the fault management of injection molding machine, and it is the original basis for fault analysis and processing, and the record must be complete and correct. After the injection molding machine maintenance workers carry out on-site inspection and fault repair, they should fill in carefully according to the content of the "Injection Molding Machine Fault Repair Form", and the workshop mechanics shall statistically analyze and submit to the injection molding machine management supervisor on a monthly basis.
6. In addition to grasping the fault situation on a daily basis, the workshop injection molding machine maintenance staff should collect the "fault repair order" and maintenance records on a monthly basis. Through the statistics, collation and analysis of fault data, the failure frequency and average failure interval of various injection molding machines are calculated, the failure dynamics and key failure causes of a single injection molding machine are analyzed, and the occurrence law of faults is found out, so as to highlight the key points and take countermeasures, and the fault information is sorted out and analyzed and fed back to the planning department, so as to arrange preventive repair or improvement measures plan, and can also be used as the basis for modifying the regular inspection interval, inspection content and standards. According to the statistical data, statistical analysis charts can be drawn, such as the dynamic statistical analysis table of a single injection molding machine failure is an effective method for the maintenance team to visually manage the fault and others, which is not only convenient for managers and maintenance workers to grasp the failure of various types of injection molding machines in a timely manner, but also has a clear goal when determining the maintenance countermeasures.
7. Through the daily inspection of the injection molding machine maintenance workers and the status inspection of the injection molding machine, the status information and fault signs obtained, as well as the relevant records and analysis data, the workshop injection molding machine maintenance personnel or repair team leader will arrange daily maintenance in time for the existence of various types of injection molding machines, make full use of the production gap time or holidays, and prevent it in advance to control and reduce the occurrence of failures. For some fault signs and hidden dangers, if the daily maintenance is not affordable, it will be fed back to the planning department to arrange planned repair.
As the core production technology for the production of plastic products, injection molding machines have been widely used in production and life, and play an increasingly important role in transportation, building materials, agriculture, catering, medical and health, national defense construction and other fields.
