As we all know, a vertical injection molding machine is a machine that shapes plastics. It can process and shape plastics. It is a very common machine in plastics processing. However, the operation of the vertical injection molding machine requires strict compliance with safety operating procedures.


So, what are the safe operating procedures for vertical injection molding machines? Here, the MH vertical injection molding machine manufacturer will tell you the detailed safety operating procedures.


Safety operating procedures for vertical injection molding machines:

1. Make preparations for operating the vertical injection molding machine.

2. Check whether the parts of the machine and the electrical control box are in good condition.

3. Check the oil level of the hydraulic oil, whether the oil storage is sufficient, start the motor and observe whether the oil output from the axial plunger valve is normal.

4. Open the cooling water valve and connect the cooling water.


A brief introduction to the safety operating procedures of vertical injection molding machines:

1. Mold loading of the vertical injection molding machine: push the mold transfer machine hook to the highest position, place the plastic mold on the moving template, unscrew the fixed template, correct the upper mold of the plastic mold and the fixed template, and tighten the screw.

2. Heating of 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 heat it sufficiently to melt the plastic.

3. Vertical injection molding machine operation: turn on the solenoid valve and move the mold machine hook up to close with the plastic mold, turn on the solenoid valve to press the injection plunger into the barrel for injection. After the injection is completed, the solenoid valve is turned on to press the injection plunger out of the barrel, and the solenoid valve is turned on to lower the hook of the mold transfer machine, and the plastic mold can be opened and demolded.


Of course, the main operating items of the vertical injection molding machine also include the control and operation of the keyboard, as well as the corresponding electrical control cabinet operating technology and hydraulic system operating knowledge. Because the pressure, speed, model and other related operations involved in the process of injecting raw materials are closely related to the above principles. 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 operating skills.
