What comes first is the first class maintenance of the motor mould. The so-called first class maintenance refers to the daily maintenance, such as cleaning, lubricating and inspecting the mould. Before the motor is installed, the surface of the motor should be cleaned in order to ensure the fitting surface and the working surface are not destroyed. After the mould is installed, the mould should be opened and cleaned again, especially the steering device.
At the same time, the sliding places of the motor mould should be lubricated through the grease. Then people should remember to inspect the whole mould carefully, especially the security components, such security sidepin, security screw, side guard plate and so on. When the motor mould is in operation, some parts (holding pad, circular bead) also should be lubricated at fixed period. Meanwhile, the waste material in the waste hole of the trimming and piercing die must be cleaned periodically. After the production is over, the maintenance still can not be overlooked. It is suggested to clean the whole motor mould carefully.
Next, it is turn to introduce the second class maintenance. It refers to the systemic maintenance at the fixed period according to the technological state and complex degree of the motor mould. The maintenance work should be finished by the professional person. Here the author will introduce the second class maintenance about the different components of a motor mould.
During the operation, the spring of the mould is one of the most easily destroyed components. It often suffers from the breakdown and transformation. The maintenance for this component is to replace it at the fixed time. However, when people replace the spring, the specification and model number should be concerned. The specification and model number can be ensured through the color, outside diameter and length. Only when the three items are the same, the spring can be replaced. As for the fastening components, they should be often checked whether they are loose or broken. If people find that they are destroyed, a better way is to replace them with the new spare parts in the same specification.
