Fault injection molding machine classification

Injection molding machine is a wide range of fault could be from a different point of view of its classification.

1. Fault by the occurrence, can be divided into:

(1) gradual onset fault. As a result of the initial injection molding machine performance arising from the gradual deterioration, most of the injection molding machine’s fault belongs to this failure. And the failure of such electronic control, hydraulic machinery parts of the yuan wear, corrosion, fatigue and creep, and so the process is closely related.

(2) sudden failure. Is a variety of factors, as well as the occasional outside influence and the role of co-produced, which went beyond the role of the injection molding machine can bear limit. For example: as a result of entering the bowl-iron overload occur and cause a broken screw; as a result of the breakdown and into the string of high-pressure injection molding machine electronic board. Such failures often occur suddenly, without any prior symptoms.

Unexpected failures occur in the injection molding machine using the stage, often due to the design, manufacture, assembly, as well as material defects, and so on, or operation errors, and regulations.

2. Demarcation according to the nature of the fault can be divided into:

(1) intermittent fault. Injection molding machine in the short term loss of some of its features, debugging will be able to resume a little repair, replacement parts and components do not need to.

(2) permanent failure. Injection molding machine has been damaged in some parts needed to replace or repair can be re-used.

3. Attainment affected by the fault can be divided into:

(1) complete failure. Injection molding machine led to the complete loss of function.

(2) partial failure. Lead to the loss of some of the features of injection molding machine.

4. Fault cause division, can be divided into:

(1) failure of wear and tear. As the injection molding machine failures caused by normal wear and tear.

(2) the wrong use of fault. Because of errors, failures caused by improper maintenance.

(3) the inherent weakness of failure. As the design, injection molding machine so that the emergence of weak links in the use of normal when the Trouble.

5. Failure by the danger of division, can be divided into:

(1) the risk of failure. For example, security systems need to move in failure due to the loss of the protective effect, resulting in personal injury and injection molding machine breakdown; electronically controlled hydraulic system failure caused by the fault, and so on.

(2) of the security failure. For example, security systems without the need for action when action; injection molding machine could not be activated when the start of the fault.

6. Injection molding machine fault by the occurrence and development of the law of division, can be divided into;

(1) random failures. Failure occurred at a time is random.

(2) there are rules of fault. The fault occurred in a certain regularity.

Each has its own failure of the main features of the so-called failure mode, or state failure. A variety of injection molding machine’s fault, it is quite complicated, but we can narrow it down several of the following: abnormal vibration, mechanical wear, the input signal so that computers can not be accepted, no output signal solenoid valve, hydraulic mechanical components break down, the ratio of linear disorders , The hydraulic pressure drop, leakage of hydraulic pump failure, hydraulic noise, circuit aging, abnormal sound, oil degradation, power supply Drop, enlarged board of exporting no SARS, temperature and other out of control. Different types of injection molding machine failure mode of a variety of different proportion.
