A. Preparation for safe operation of vertical injection molding machine:
1. Preparation
2. Check whether all parts of the machine and the electrical control box are in good condition.
3. 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.
4. Open the cooling water valve and connect the cooling water.
B. Introduction to safe operation procedures of vertical injection molding machine:
1. Mold loading of vertical injection molding machine: 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. Heating the barrel of the vertical injection molding machine: Turn on the electric heating switch of the electrical control box, add plastic into the barrel, and fully heat it to melt the plastic.
3. Operation of vertical injection molding machine: 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, turn on the solenoid valve 6 to press the injection plunger out of the barrel, and turn on the solenoid valve 8 to make the mold shifting mechanism descend, and then the plastic mold can be opened and demolded.
Of course, the main operation items of the vertical injection molding machine also include the control and operation of the keyboard, and the corresponding electrical control cabinet operation technology and hydraulic system operation knowledge. Because the pressure, speed, type and other related operations involved in the process of injecting raw materials are closely related to the above items. At the same time, the control of the temperature in the barrel and the adjustment and monitoring of the current and voltage require the operator to have certain relevant knowledge and operation skills.
