Close the front safety door
If additional action is required, it must be confirmed by the technician as a necessary action for normal production before operation.
2、Any action other than this must be carried out in the manual state, after shutting down the oil pump; where electrical is involved, the power must also be turned off, for example, when the work may touch the injection nozzle and molten rubber cylinder.
the power must be turned off for safety, before cleaning the mold or adjusting any mechanical parts, the power must be cut off.
3、When the equipment is automatically alarmed, the operator must immediately withdraw from the equipment range and switch to the "manual" state.
4、In case of emergency (personal accident, sudden abnormal sound from equipment and mold), immediately press the emergency stop button and shout for help.
5、When the machine is running, it is strictly forbidden to put any part of your body into the closed safety door; open the safety door before putting your hand into the mold. turn off the oil pump if the upper body enters the middle of the two templates during inspection and repair.
no matter what the occasion is, the power should be cut off first when the whole body enters the two templates.
6、When the machine is running, the rear safety door must be closed and the front safety door must be used to control the opening and locking of the mold.
7、When the machine is running. Before anyone other than the operator of the injection molding machine touches the machine, the operator of the machine must be notified to switch to the manual state and shut down the oil pump.
Especially when multiple people work together, before any abnormal action of either party, you must notify the co-workers and get confirmation before working.
-The injection molding machine operator is the person who operates the injection molding machine for production and debugging, and may be a stopper, a top worker, or a debugger.
-Abnormal action: The action other than the action listed in the first clause.
8、respectively, in the manual and semi-automatic state, check whether pulling open the safety door can cut off the oil pump and power supply.
9、Check whether the emergency stop button is effective and whether the oil pump and power supply can be cut off when pressed.
10、Ensure that there is no oil and water around the equipment and equipment to ensure the safety of walking.
11、Find abnormalities of injection molding machine (oil leakage, damaged electric wire, damaged electrical plug, etc.) and report to the shift manager or technician in time.
12、When removing the nozzle, protective measures must be taken to avoid high temperature raw materials and gas splash burns.
13、Do not operate this machine when cleaning the obstruction or moving the hopper.
14、When injecting into the air, close the front and rear safety doors, and no one should stand on either side of the barrel to avoid lifelong regret for the damage of the rubber shot.
15、After the machine has been out of use for a long time, it must be checked that the safety devices (such as mechanical locks, safety door travel switches and hydraulic locks, etc.) are normal before running the equipment.
16, maintenance operations, cut off the main power supply, hanging "no power" sign, before running, to confirm that the machinery is connected in accordance with the provisions.
17、When the injection table is moving forward, do not use your hands to remove the molten glue leaking from the injection nozzle to avoid hurting your hands.
18、Magnetic frame must be put in the hopper to prevent damage to the injection molding equipment by mixing with metal foreign objects.
19、 inspection, repair, such as the upper body into the middle of the two templates, should turn off the oil pump.
20、no matter what the occasion, the entire body into the two templates should first cut off the power.
21、Any alteration of safety equipment is not allowed, and no production of equipment should be started in the state of damaged safety devices.
22、Production of high temperature products (mold temperature higher than 120 degrees) must use thick cotton gloves.
Third：the mold, oil temperature machine safety production instructions.
1、The power supply must use the specified voltage (220V/380V/415V/50/60Hz).
2、Do not use heat-conducting oil of unknown status.
3, the power cord must use the specified specifications of the product to prevent overheating, voltage drop, accidents or failures.
4、Be sure to connect the ground terminal of the machine to the ground wire.
5、All the hoses and other devices used to connect the devices must be heat resistant to 120℃ and pressure resistant to 1000kpa (10kgf/cm 2 ).
