Return of the holiday -- note for opening and closing blow molding machine

The hollow blow molding machine must be strictly prepared before starting the machine. Its main contents include the following eight points:

The first point: the cooling water of the cooling cylinder must be completely opened to avoid screw biting.

The second point: preheating hydraulic oil. If the temperature of the hydraulic oil in the hollow blow molding machine tank is too low, the heater should be opened immediately.

The third point: press the start button to stop immediately and check whether the running direction of the pump is correct. If it is found that there is no corresponding immediately replace the two phase motor power line.

The fourth point: machine opening should be carried out under the condition of no pressure of the hydraulic system. After opening, the pressure of the overflow system of the pump should be adjusted to the safety pressure. In the large blow molding machine, there are two pressure systems, one is the clamping unit, the other is the blow molding unit, and the two units have one pressure vent valve. After the pump stops, the pressure vent valve must be opened when the pump works. The pressure vent valve must be closed.

The fifth point: adjust the position of all the travel switches, so that the moving template can be switched off smoothly.

The sixth point: close the complete door. According to the requirement of safety protection, all the safety doors should be closed when the machine is working. For large hollow blow molding machine, opening the safety door and clamping movement will be stopped, and if the other safety door is opened, the oil pump will stop.

The seventh point: connect heating and temperature regulation system;

The eighth point: install the mold. When installing the mold, the mold surface and the contact surface with the hollow blow molding machine template must be cleaned.

Notes for shutdown:

The first point is: when the downtime, each speed is reset to zero, and the heating sections are closed one by one.

The second point: close the mold, blow the needle away from the mold half centimeter, prevent the hard object from falling into the mold and cause injury.

The third point: for mold rust treatment, such as long shut-down time, need to clean up the internal water of the mold, prevent rust and clogging;

The fourth point: turn off the total power supply, lubricate the equipment, add lubricating oil, clean the whole machine, and close the string of water.

The fifth point: the screw inlet must be covered with fabric or cloth, isolating impurities, air and moisture.https://www.czplasticfactory.com/products/
