Today we’ll show you the key points of operation of the carrier tape injection molding machine

Before power on

1. Before the operation of the injection molding machine, check whether there is water and oil in the electrical control box. If the electrical appliance is damp, do not start it. Maintenance personnel shall blow dry the electrical parts before starting the machine.

2. Before the operation of the injection molding machine, check whether the power supply voltage meets the requirements, which generally shall not exceed ± 6%.

3. Check whether the emergency stop switch and front and rear safety door switches are normal. Verify whether the rotation direction of motor and oil pump is consistent.

4. Check whether all cooling pipes are unblocked, and feed cooling water into the oil cooler and the cooling water jacket at the end of the barrel.

5. Before the operation of the injection molding machine, check whether there is lubricating oil at all moving parts and add enough lubricating oil.

6. Turn on the electric heating to heat each section of the barrel. When the temperature of each section meets the requirements, it shall be kept warm for a period of time to stabilize the temperature of the machine. The holding time varies according to the requirements of different equipment and plastic raw materials.

7. Add enough plastic into the hopper. According to the requirements of different plastics for injection molding, some raw materials should be dried first.

8. Cover the heat shield on the cylinder, which can save electric energy and prolong the service life of electric heating ring and current contactor.

Operation process of injection molding machine

1. Do not cancel the function of the safety door for convenience.

2. Pay attention to observe the temperature of pressure oil, and the oil temperature shall not exceed the specified range. The ideal working temperature of hydraulic oil should be kept between 45-50 ℃, generally in the range of 35-60 ℃.

3. Pay attention to adjusting each travel switch to avoid impact during operation of the machine.

end-of-job

1. After the operation of the injection molding machine, the plastic in the barrel shall be cleaned to prevent residual material oxidation or long-term thermal decomposition.

2. The mold shall be opened so that the toggle mechanism is locked for a long time.

3. The workshop must be equipped with lifting equipment. Be very careful when assembling and disassembling the mold to ensure production safety.
