Necessary for maintenance of injection molding machine

The core of injection molding machine maintenance work is fault judgment and fault handling. It involves a wide range of knowledge, a large degree of complexity, and has a certain depth (such as the level of comprehensive professional knowledge). We should have the basic knowledge of mechanical equipment maintenance, hydraulic maintenance and electrical maintenance. In fact, the maintenance work of injection molding machine is hard, but it is also a process of continuous learning and enterprising. As long as you master the basic working principles and basic working methods of injection molding machine, no matter what types of machine are, you can explore a set of maintenance procedures to ensure the normal operation of injection molding machine.

Maintenance workers must first understand and master the contents of the operation manual of the injection molding machine, familiar with and master the mechanical parts, circuit and oil circuit of the injection molding machine, understand the working process of the machinery, circuit and oil circuit of the injection molding machine in normal operation, and understand and master the inspection and maintenance methods of electrical components and hydraulic components. Clear the normal working state and abnormal working state, in order to avoid misjudgment and disassembly.

Maintenance work must understand the operation method of the equipment and have some basic knowledge of injection molding, and can correctly use the injection molding machine. If you do not know how to operate the injection molding machine, the maintenance work is very difficult, and the judgment of fault may not be reliable. In the injection molding machine, the circuit board and electrical components are affected by high temperature, environment, time and other factors for a long time. Therefore, debugging injection molding machine is also one of the essential basic skills in maintenance work. It is very important to understand the working procedure of injection molding machine, debug the electronic circuit and hydraulic oil circuit of injection molding machine.

In order to make the maintenance work accurate, reliable and timely, it is necessary to study and master the contents in the operation manual of various types of injection molding machines. In the general maintenance process, the maintenance idea is usually circuit oil circuit mechanical parts action. If the output of the circuit is normal, adjust the oil circuit valve. If the oil circuit works normally, adjust the circuit electronic board. Of course, in the end, there will be a unified adjustment, but the three relationships are interdependent and mutually controlled. The correct use of instruments and meters, adjusting the detection circuit, repairing the oil circuit, debugging the position and action of the mechanical part are the important means to judge the fault. Generally, injection molding machine manufacturers only give the electrical block diagram of the equipment, the block diagram of the oil circuit and the main parts of the machinery, which is not enough for the maintenance work. Must pay attention to the daily maintenance work, collect, sort out all aspects of the relevant information. Such as electrical, electronic, mechanical spare parts, oil circuit, electromagnetic valve body, etc. For example, if there is an opportunity in the electrical field, it is necessary to map the schematic diagram of the circuit, the schematic diagram of the electronic board and the actual wiring diagram, and measure the devices corresponding to the terminals, so as to provide accurate detection points for fault judgment and analysis in maintenance. The specific parameters of the detection point are measured. When necessary, it is necessary to make its own power supply, simulate input and output signals, conduct simulation test or adjustment, so as to master and obtain the first-hand maintenance data, such as the parameters of working points at all levels.

The same is true of oil circuit maintenance, which must be adjusted and maintained according to the characteristics of oil circuit and oil pressure solenoid valve. Remove, clean, inspect and install the solenoid valve frequently when possible. These treatments can cause a lot of trouble, but they are crucial.

The maintenance work must master and sort out the maintenance method and judgment program diagram of the system fault in accordance with the principle and logic. In combination with the daily maintenance work, collect the relevant information of the injection molding machine, such as fault treatment. The methods include step-by-step inspection method, simulation inspection method, voltage test method, on-off test method, circuit board replacement method, etc. After the repair, it is necessary to readjust the working point, readjust and carry out the load test to make the equipment work within the parameter range of the data listed in the operation manual.
