1. Be sure to turn off power switch of motor and electric heating before powering on.
2. Check whether circulating cooling water is unblocked. When machine is started and electrified, it must be ensured that hydraulic oil and circulating cooling water of barrel have been opened and unblocked.
3. If machine is equipped with a centralized lubrication device, check amount of oil in device before starting machine. Before oil level drops and open warning line, refill lubricating oil and inject oil to specified oil level.
4. When machine is started, first use jog start (that is, press motor start button, motor starts, then disconnect, 1-2 seconds, then repeat jog start and disconnect 3 to 4 times. When oil pump and motor are moving, listen for abnormal noise, and stop operation immediately if there is abnormal noise.)
5. Check parameters of machine during operation, first put machine in manual state, press relevant buttons, visually observe pressure gauge, you can predict pressure of each section. When electric heating is not heated to set value (temperature during normal operation), remember not to start hydraulic motor, operate feed, inject, shoot back, etc. , Otherwise it may cause malfunction or damage to machine.

 

6. Two mold clamping buttons on the front of machine (one on the left and one on the right, green) must be pressed at the same time with both hands during operation. One-handed operation is strictly prohibited: (that is, first press one of buttons with an object to make button in a conductive state, then only use the other button to operate the other button to lock mold, which will cause broken hands.)
7. When checking and adjusting functional parameters of injection molding machine, turn off power of motor and oil pump as much as possible. If it is unavoidable, please be especially careful. It is strictly forbidden to operate keys on control panel of machine with one hand, while the other hand is doing any work within lock mold area or touching any moving parts on the machine. It is absolutely forbidden for two people to operate a machine(that is, one person operates keys on machine control panel, while another person operates or is in contact with moving parts within clamping area).
8. Operate horizontal injection molding machine: When safety door is opened, it must be confirmed that stopper can automatically fall at mold opening stop position, and do not move bumper, stopper or bumper cover. When machine stops when mold is opened but has not reached end position, mechanical safety device does not work, and it is necessary to understand its criticality.
9. Check safe operation of machine: put machine in manual state, press mold opening button, and let machine fully open mold to end position. At this time, observe whether end position of machine mold opening is at set position. If mold opening exceeds set end position, machine is malfunctioning and cannot work;
When machine is in manual state, press mold lock button to fully lock machine (to the end position of mold lock), and then press red sharp rise switch in the middle of front of machine, machine will open mold to set end position ; Or put machine in a semi-automatic state, start motor, press the two mold clamping buttons on the front of machine at the same time with both hands (one on the left and right sides, green) and machine quickly closes mold. When mold is closed in slow motion, release your hands and quickly press button in the middle of front of machine (red, sharp rise switch). Mold clamping should be terminated immediately, and machine quickly opens mold to fully open closing mold to end position. If you press sharp rise switch, mold clamping is not terminated immediately and mold clamping is continued. At this time, motor should be turned off immediately to stop machine for repair;
Machine is equipped with a mold clamping induction device. Turn on machine, start motor, press electric heating, mold adjustment, and mold opening keys respectively to make mold open to set end position, then hold object with one hand and place it carefully in mold clamping sensing area. Sensor light will light up, and press mold-locking switch with the other hand. At this time, there should be no movement of mold-locking, and mold will not be closed, or press clamping switch with one hand first, and machine will slowly close mold downwards. At this time, hold object with the other hand and place it carefully in induction area of mold clamping. At this time, mold clamping should be terminated immediately, and machine will quickly open mold to fully open closing mold to end position before it can be used normally, otherwise it will be shut down for repair.
10. When inspecting machine or doing any work on machine, before touching any moving parts or pressure electrical parts, you must remember safety operation issues, and you must first cut off power supply of oil pump motor to ensure safety.
11. When mouth (nozzle) is advancing (down), do not remove salivation resin from nozzle (nozzle) with bare hands. Injection should be stopped, and tools such as iron pliers (clamps) should be used to remove it, not to mention directly operating by hand.
12. Shutdown. When completing work or when there is a sudden power failure, for the sake of safety and protection of electrical equipment, power switch should be turned off.
Remember: Failure to implement above-defined operating procedures may result in serious danger and machine failure.
