Vertical injection molding machine is a mechanical device. Usually consists of injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc. Many people do not know how to operate a vertical injection molding machine. Today, I will explain it!

Vertical injection molding machine

First of all, preparatory work to check whether the various parts of the machine and the electrical control box are in good condition. Check the oil level of the hydraulic oil, whether the oil storage is sufficient, and start the motor to observe whether the oil output from the axial plunger valve is normal. Open the cooling water valve to connect the cooling water.

Push the mold transfer mechanism to the highest position, install the plastic mold on the moving mold plate, unscrew the fixed mold plate, correct the upper mold and the fixed mold plate of the plastic mold and tighten the screw, fasten the plastic mold lower mold on the moving mold plate, and run the mold transfer mechanism, check whether the mold position is correct. Barrel heating: Turn on the electric heating switch of the electrical control box, add plastic into the barrel, and fully heat the plastic to melt.

Vertical injection molding machine injection operation: turn on the solenoid valve 8 to make the mold transfer 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 is completed, the solenoid valve 6 is turned on to push the injection plunger out of the barrel, and the solenoid valve 8 is turned on to lower the mold shifting mechanism, and the plastic mold can be opened and demolded.

Regularly check the electrical parts, remove dirt, oil and dust, keep the electrical contacts clean, and often remove the dirt and dust on the joints. The vertical injection molding machine has accumulated rich experience and common problems in the long-term and large-scale maintenance.
