How to disassemble the screw of the blow molding machine？

Blowing machine debugging is blowing machine before the formal operation of production, must also be a very important step. The debugging effect of the machine will directly affect the production of blow molding machine and the quality of blow molding products. Especially the debugging of large hollow blow molding machine, because the production process of large hollow blow molding machine is much more complex, there are many places to control, therefore, this article will share with you the debugging skills and methods of large hollow blow molding machine.

Start blow molding machine, then immediately stop, the purpose of this operation is to check whether the pump running direction is correct, such as found running direction is wrong to replace the power cord immediately.

The cooling water of the cooling cylinder is guaranteed to be smooth.

Switch on the heating system and temperature control system.

Before the blow molding machine starts, the temperature of the hydraulic oil needs to reach a certain value, so it is necessary to preheat the hydraulic oil before starting. If the temperature of the hydraulic oil in the oil tank of the blow molding machine is too low, the heater should be started immediately, as the large hollow blow molding machine is generally equipped with a special heater.

The blow molding machine should be started under the condition of no pressure in the hydraulic system. After starting, adjust the system pressure of each pump to the standard pressure value. There are usually two parts of the pressure system in the large hollow blow molding machine, one is the die closing part, the other is the extruder unit, and each of the two units has a pressure vent valve. After the pump stops running, the pressure relief valve needs to be opened, and then closed when the pump is working.

Adjust the position of all the stroke to make the activity template run smoothly.

Before installing the mold, the surface of the mold and the contact surface with the machine template must be cleaned, so as to avoid affecting the production process of the machine and the mold cannot function normally.

In the case of blowing machine without raw materials, it is necessary to manually operate the machine for several times, observe whether the indicator light, travel switch and various actions are correct and sensitive, and check whether some small fastening parts are loose.

Check the oil level of the hydraulic oil in the oil tank of the blow molding machine to ensure that the supply of hydraulic oil and lubricating oil is sufficient.

Switch on the main power supply and the main switch on the control box.

The blow molding machine should be started in the case of no pressure in the hydraulic system. When should the pressure value be adjusted? Just adjust to normal pressure after the blow molding machine is started. Run the machine in semi-automatic and fully automatic mode respectively to check whether it runs smoothly.

The above is about the debugging skills and methods of large hollow blow molding machine. In a word, the debugging of blow molding machine is a key step before the production of blow molding machine.
