What are the common electrical faults of vertical injection molding machine?

    When the injection molding machine control circuit common failure, the first thing to do is to ask, look, listen, listen, to ensure that there is a certain number in the heart. The problem is to explain the common faults of the injection molding machine operator or the worker reporting the common faults and to ascertain whether all adjustments or replacement of components were made before the common faults occurred. In the process of doing; The so-called look, is to observe whether each component works normally, to see whether the various data signals of the control circuit are appropriate, to see whether the appearance of the electrical components color change, etc.; LIS means listening to the squeak of the power circuit as it works; Called smell, listen to power circuit components. Does the device smell wrong? After completing the above work, you can find the common faults of the electric power supply circuit by the following ways.

 1. Procedure Procedure Inspection Method: The injection molding machine is required to execute the procedure. Each operation must go through the whole process of the cycle system of clamping, seat-locking, injection, water-cooling, melting, ejecting, seat-locking, ejecting, ejecting, ejecting, ejecting, ejecting, ejecting and ejecting. At least each step is called a work phase, and each work phase is established. There is usually a separate control loop. The procedure flow check method is to determine the stage in which the common faults mainly occur, so as to determine the position of fault detection. Purposiveness is the key to fault detection. This method is not only suitable for electrical system with contact, but also suitable for automatic control system without contact, such as PC automatic control system or single-chip automatic control system.

  2. Static data resistance measurement method: & Static data resistance method means that it is normal to measure the point resistance of the power supply circuit with the digital multimeter resistance in the case of power failure. Since all electronic components are composed of one Pn, their forward and reverse resistance values are different, and all electronic components are different. The device also has all necessary resistors, which are connected to the power switch of the circuit or electrical component. The resistance value is not equal to zero or infinity, so if the resistance value meets the requirements, measuring the resistance value can distinguish between the advantages and disadvantages. This method can also be used to check the quality of electronic circuits, and it is safer.
