Everyone knows that a vertical injection molding machine is a kind of machine that shapes plastics. It can process and shape plastics. It is a very common machine in plastics processing. However, the vertical injection molding machine needs to be operated in strict accordance with the safety operating regulations during the operation and use process.
So, what are the safe operating procedures for vertical injection molding machines? MH is a vertical injection molding machine manufacturer. Today, the MH injection molding machine manufacturer will introduce the detailed safety regulations of the vertical injection molding machine:
A. Preparations for the safety operation regulations of the vertical injection molding machine:
1. Check whether the parts of the machine and the electrical control box are in good condition.
2. 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.
3. Open the cooling water valve to connect the cooling water.
B. Brief introduction of safety operation regulations of vertical injection molding machine:
1. Mounting of vertical injection molding machine: push the hook of the transfer mold to the highest position, install the plastic template on the movable template, unscrew the fixed template, correct the upper mold of the plastic mold and the fixed template, and tighten the screw to tighten the plastic mold Fix it on the moving template, run the moving mold mechanism to check whether the mold position is correct.
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. Operation of the vertical injection molding machine: turn on the solenoid valve to raise the hook of the mold transfer machine and close the plastic mold, turn on the solenoid valve to insert the injection plunger into the barrel for injection. After injection, the solenoid valve is turned on to push the injection plunger out of the barrel, and the solenoid valve is turned on to lower the hook of the mold transfer machine, and then the plastic mold is 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 operating knowledge of the corresponding electrical control and hydraulic system. Because in the process of injecting raw materials, the pressure, speed, type and other related operations are closely related to the above.
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 techniques.
