1. Safety preparation before operating the injection molding machine
Train qualified personnel to operate
The operation of the injection molding machine involves complex mechanical and electrical control knowledge. Untrained personnel are not allowed to operate without authorization. Enterprises should organize systematic safety training, including equipment structure, operation process, emergency handling, etc., to ensure that operators are familiar with equipment performance and safety requirements. Operators should hold a valid operation qualification certificate before they can work.
Check the condition of the equipment
Before starting the machine each time, the operator should conduct a comprehensive inspection of the injection molding machine:
Is there any oil leakage in the hydraulic system, and is the hydraulic oil sufficient and uncontaminated.
Is the electrical circuit intact, and are the switch buttons and control panel working properly.
Is the safety protection device (such as safety door, safety grating) installed in place and running sensitively.
Is the mold installed firmly, and are the screws and clamping devices tightened.
Ensure that the equipment is in a safe and stable state to reduce the probability of accidents.
Wear protective equipment
To prevent mechanical pinching, thermal burns or splash injuries, operators must wear standard personal protective equipment (PPE), including safety gloves, protective glasses, protective shoes, etc. The operation site should be kept clean to prevent tripping or slipping accidents.
2. Safety regulations during operation
Strictly abide by the operating procedures
The operation should be carried out in accordance with the equipment operation manual and company rules and regulations. It is strictly forbidden to adjust the machine parameters at will to avoid mechanical failure or safety hazards caused by overload of equipment.
The operation process should be standardized to avoid missing operation steps, such as: mold opening and closing sequence, injection cycle setting, cooling time confirmation, etc.
Stay alert and avoid hands approaching the mold
The mold is powerful and fast when closing the mold. If the hand or body part enters the mold space, it is very easy to be pinched or cut off. Therefore, the operator needs to stay focused at all times and never reach out or reach into the mold action area at will.
Use safety protection devices
Modern injection molding machines are equipped with safety protection devices such as safety doors, safety gratings, and emergency stop buttons. Operators should ensure that these devices are intact and working properly, and must not be dismantled or shielded without authorization. The safety device can automatically shut down when danger occurs, greatly reducing the risk of accidents.
Prohibition of operation after drinking and fatigue
Alcohol and fatigue will seriously affect the judgment and reaction speed of operators, leading to operational errors. Enterprises should strictly manage the working status of operators to ensure that they are in the best condition for operation.
3. Abnormal injection molding machine and emergency treatment
Stop the machine in time when encountering abnormalities
If there are abnormal sounds, increased vibrations, oil leakage in the hydraulic system or other abnormal phenomena during the operation of the injection molding machine, the machine should be stopped immediately to prevent the problem from worsening and causing greater damage or safety accidents.
Use of emergency button
There should be a prominent emergency stop button at the operation site. When the operator and the surrounding personnel find an emergency, they can quickly press the button to cut off the power supply and stop the equipment quickly to avoid the expansion of the accident.
Report maintenance personnel
Non-professionals are not allowed to disassemble or repair the injection molding machine without authorization. In case of equipment failure, professional maintenance personnel should be reported to for inspection and maintenance as soon as possible to ensure that the maintenance process is safe and standardized to avoid secondary injuries.
4. Safety precautions for maintenance and maintenance
Power-off operation
All maintenance, maintenance, and cleaning work must be carried out when the equipment is completely powered off and there is no residual pressure to prevent the machine from suddenly starting or the hydraulic system from accidentally moving and causing personal injury.
Keep clean
The production site should be kept clean and tidy to prevent oil and waste accumulation from causing slips, fires or equipment damage. Clean the injection molding machine and its surroundings regularly to ensure that the safety passage is unobstructed.
Check safety devices
Regularly test and verify the functions of safety protection devices to ensure that safety doors, gratings, emergency stop buttons and other devices are sensitive and effective. Once a safety device is found to be ineffective, it should be repaired or replaced immediately to prevent accidents.
