What precautions should be taken for safe operation of injection molding machines
Starting from the production state of injection molding machines, their strong, high-speed, high-temperature, and high-pressure properties mean that they have a certain degree of danger. The so-called "beer machine jamming" refers to injection molding machine accidents. So, what are the common safety accidents that occur in injection molding machines? Why did the accident occur? How to ensure the safety production of injection molding factories? With the above questions in mind, let's answer them one by one.
1. Hand pinched by mold
For example, if the machine settings are changed without authorization and the operator is not focused on the operation, resulting in non-standard operation, there is a risk that the operator will be injured by the mold.
2. Hand injured by a needle
During the adjustment of the top pin, due to improper and unsafe operation, the fingers or hands were crushed and fractured by the top pin positioning plate.
3. Head comminuted fracture
Due to troubleshooting or maintenance requiring the head and arms of the human body to enter the danger zone, but without cutting off the power supply of the injection molding machine or turning off the injection molding machine motor, the equipment suddenly malfunctioned and acted, resulting in overall compression injury to a certain part of the human body.
4. High temperature molten material splashing
The injection molding machine cannot discharge material, and the corresponding hopper mouth does not discharge material, so the hopper was dismantled for inspection. During the inspection, the adhesive glue in the barrel suddenly sprayed out from the discharge port, causing severe burns to the operator's face.
5. Burn accident
Improper management of hazardous chemicals resulted in an employee placing a bag of product cleaning agent on the mold warmer, causing a large fire.
6. Fire accident
The material worker soaked the red hot ejector pin in the white electric oil used by the technician to clean the mold inserts, causing a large fire.
1、 The main hazardous areas of injection molding machines include: feeding area, material pipe cover area, nozzle area, mold area, mold support area, locking mechanism, etc. The policy of "safety first, prevention first" should be adhered to, and education and publicity work on safety production should be strengthened; If necessary, practical exams can be conducted on the premise of providing training on safety production knowledge.
2、 The influencing factors of safety accidents in injection molding machines include mechanical hazards, thermal injury factors, electrical injury factors, harmful substances, environmental factors, and unsafe human behavior factors. Therefore, it is necessary to formulate a "Safety Code for Injection Molding Department Employees" and a "Safety Code for Loading and Unloading Mold Personnel", carry out safety signs, strengthen safety production inspections and the implementation of safety production management systems, and eliminate safety hazards.
3、 We also need to do a good job in fire prevention in the injection molding workshop and ensure that the safety passage is unobstructed.
4、 During operation training, provide standardized examples and explain in detail the safety operation/usage management regulations for fixtures (such as quantity, sequence, time, purpose, positioning, etc.), and conduct relevant practical assessments for new employees.
The above brief introduction to the safety of injection molding machines ends here. Do you know how to ensure the production safety of injection molding machines?
