injection molding machine operation precautions
Thank you all for your long-term attention to Lixun injection molding machines. Lixun injection molding machines will continue to push more products, injection molding machine maintenance,
mold maintenance, plastic science, safe use and other small knowledge for everyone.
When we use and manage injection molding machines, we should follow the following principles: scientific management, correct use, reasonable lubrication, careful maintenance,
regular maintenance, and timely maintenance. In the long run, it can extend the service life of the machine and ensure the integrity of the equipment. Today,
Lixun Machinery will give you a popular science of the precautions for injection molding machine operation.
1. When lifting, if the force is applied to the pull rod, it must be protected with soft objects, otherwise it will cause scratches.
2. Before use, the injection molding machine must be lubricated; during use, it should be noted that the time interval between two lubrications should not be too long to ensure that the lubrication of
related parts is in good condition, and attention should also be paid to the lubrication of other lubrication points.
3. When the power supply is just connected to start the injection molding machine, attention should be paid to the direction of the motor. If the oil pressure cannot be raised, it may be that the
direction of the motor is connected in reverse. At this time, the order of the phase lines must be adjusted to ensure that the direction of the motor is correct.
4. Injection molding machines are generally equipped with mechanical safety devices, electrical safety devices, and hydraulic safety devices. It is strictly forbidden to operate and use the
injection molding machine without any safety device.
5. The position of the electronic ruler has been set before leaving the factory, or it is set on-site by relevant technical personnel during installation. Once adjusted, it should not be changed again.
6. The internal detection function of the circuit shall not be used by the operator without authorization.
7. During operation, the following matters should be noted.
1. Do not cancel the function of the safety door for the sake of convenience.
2. Pay attention to the temperature of the hydraulic oil and control it within the specified range.
3. Pay attention to adjust the travel limit switches to avoid collisions during the operation of the injection molding machine.
4. When the injection molding machine sounds an alarm, you must see the prompts on the fluorescent screen clearly. Sometimes the manual operation key can release the alarm.
Don't be in a hurry to turn off the power.
8. It is not advisable to use unclean hydraulic oil to avoid clogging the pipeline and reducing the service life of the hydraulic valve.
9. When switching to another raw material, clean up the waste material trapped in the barrel to avoid affecting the quality of plastic parts.
10. Do not change the on and off state of the travel switch at will.
11. Ensure the smooth flow of cooling water to prevent the oil temperature from being too high, which will accelerate the oxidation of the hydraulic oil and deteriorate the oil quality;
reduce the viscosity and leak in some places; accelerate the aging of the seal.
12. When a fuse burns out, do not replace it with another one at will, but consult, receive or purchase it from the injection molding machine manufacturer or agent.
13. At the end of work, pay attention to the following matters.
1. Before stopping the machine, clean the plastic in the barrel to prevent the residual material from oxidation or long-term heat degradation.
2. The mold and injection molding machine should be dust-proof and rust-proof.
