Method of repairing vertical injection molding machine

The core of the vertical injection molding machine maintenance work is the judgment of the fault and the treatment of the fault. It involves a wide range of knowledge, a large level of complexity, and a certain depth. You must have basic knowledge of mechanical equipment maintenance, basic knowledge of hydraulic maintenance, and basic knowledge of electrical maintenance.

Maintenance workers must first understand and master the contents of the operating instructions of the injection molding machine, be familiar with and master the mechanical parts, circuits and oil circuits of the injection molding machine, and understand the working process of the mechanics, circuits and oil circuits of the injection molding machine during normal operation Master the inspection and maintenance methods of electrical components and hydraulic components. Know the normal working state and the abnormal working state to avoid time-consuming misjudgment and wrong disassembly.

For maintenance work, it is necessary to understand the operation methods of the equipment and have some basic knowledge of injection molding, and to use the injection molding machine correctly. If you don’t know how to operate the injection molding machine, the maintenance work is very difficult, and the fault judgment may also be unreliable. The circuit boards and electrical components in the injection molding machine are temporarily affected by factors such as high temperature, environment, time, etc., the operating point of the components is shifted, and the aging level of the components is within the normal range.

Therefore, debugging an injection molding machine is also one of the essential basic skills in maintenance work. It is very important to understand the working sequence of the injection molding machine and to debug the electronic circuit and hydraulic circuit of the injection molding machine.

To be accurate, reliable and timely for maintenance work, it is necessary to study and master the contents of the operating instructions of various types of injection molding machines. In the general maintenance process of injection molding machines, the maintenance idea is usually circuit-oil circuit-mechanical components. The adjustment work is reversed.
