Vertical Injection Molding Machine Operating Procedures

1.Preparation
1.1. Check whether all parts of the machine and the electrical control box are in good condition.
1.2. Check the oil level of the hydraulic oil and whether the oil storage is sufficient. Start the motor to observe whether the oil output of the axial piston valve is normal.
1.3. Open the cooling water valve and connect the cooling water.
2. Operation
2.1. Mold loading: Push the mold shifting mechanism to the highest position, install the plastic mold on the mobile template, unscrew the fixed template, calibrate the upper mold and the fixed template of the plastic mold and tighten the screw, fasten the lower mold of the plastic mold to the mobile template, operate the mold shifting mechanism, and check whether the mold position is correct.
2.2. Barrel heating: Turn on the electric heating switch of the electrical control box, add plastic into the barrel, and fully heat it to melt the plastic.
2.3. Injection molding operation: Turn on the solenoid valve 8 to make the mold shifting mechanism rise and close the plastic mold, and turn on the solenoid valve 6 to press the injection plunger into the barrel for injection molding. After the injection molding is completed, the solenoid valve 6 is turned on to press the injection plunger out of the barrel. After the solenoid valve 8 is turned on to lower the mold transfer mechanism, the plastic mold can be opened and demolded.
3. Maintenance and care
3.1. Check whether the hydraulic oil storage is sufficient. If it is insufficient, it should be replenished in time, and the oil should always be kept clean.
3.2. Lubrication points should be regularly lubricated according to regulations, and the oil filter should be cleaned regularly. Keep the area around the machine clean and do not allow dirt to enter the oil tank.
3.3. After use, the dirt on the machine should be wiped off, and the smooth surface should be oiled
3.4. Regularly check the electrical parts, remove dirt, oil and dust, keep the electrical contacts clean, and frequently remove dirt and dust on the joints.
Injection molding machines have accumulated rich experience in long-term and large-scale repair and maintenance work. Common problems
