Treatment of fault judgment and fault is the core work of the injection molding machine repair. It involves a wide range of knowledge, complexity, has a certain depth (such as comprehensive professional knowledge level). Not only have the basic knowledge of mechanical equipment repair, but also have a basic knowledge of hydraulic repair, also should have basic knowledge of electrical repair. In fact, the injection machine repair is difficult, but it is a process of learning and enterprising, as long as the master of the injection molding machine working principle, master the basic method of work, regardless of various models, not deviate from the, to explore a set of repair work programs, in order to ensure the normal work of the injection molding machine operation. Repair workers must first understand and grasp the injection molding machine operation the content specification, mechanical components, circuit and circuit are familiar with and master the injection molding machine, injection molding machine, to understand the working process in normal working circuit and the oil path, inspection and repair of understanding and knowledge of electrical components, hydraulic components using the method. Clearly the normal working state and not the normal working state, to avoid the error judgment and error removal.
  Repair work must understand the operation method of equipment and have some basic knowledge of injection molding, and the proper use of injection molding machine. If you do not know the operation of injection molding machine, maintenance work is very difficult, to judge the fault may not be reliable. Influence of circuit board and electrical components of injection molding machine by high temperature environment, long-term, time and other factors, the device migration, aging components, all belong to the normal range. So, one of the basic skills essential for debugging injection molding machine is in repair work. Knowledge of injection molding machine working procedures, debugging of electronic circuit, injection molding machine hydraulic system is a very important step.
  Repair work to be accurate, reliable and timely, must be content to various types of injection molding machine instructions to study and master, general repair process, repair method is usually circuit -- oil -- mechanical components. And the adjustment in turn, such as mechanical movements and clamping pressure, can seek a circuit and circuit, such as circuit output is normal, adjusting the oil valve. If the circuit work normally is adjustable electronic circuit board. Of course, the last adjustment, but the three relations of mutual dependence, mutual control. The correct use of instruments, calibration detection circuit, circuit debugging maintenance, position and action of the mechanical parts, is an important means to judge the fault. The main part of diagram box manufacturer general injection molding machine is equipment electrical diagrams, circuit and mechanical, which is not enough for repair work. Must pay attention to routine maintenance work, the relevant data collection, collation of all aspects of.
