    Injection molding machine at work need to pay attention to what place?

    Injection molding machine itself has the characteristics:

    l, injection molding machine fixed asset investment, large scale of production, consumption of more raw materials, high labor productivity, a large value. It is a high labor efficiency of production organization.

    2, injection molding machine consists of mechanical, hydraulic, electrical, special fittings and other components, as needed injection molding process technology, organically combined, high degree of automation, closely related to each other. Injection molding machine can be three classes 24h continuous operation. If a component injection molding machine failure will result in downtime.

    3, injection molding machine is simple to operate, employing less, but the injection molding machine management and maintenance of high-tech, big workload.

    4 modern injection molding machine production, due to the complex structure of injection molding machines, high degree of automation, hydraulic, electrical and mechanical control very closely linked, so that the injection molding machine failure, even partial failure, will cause the entire injection molding machine production.

    5, injection molding machine work quickly under the strong, high-speed, high-temperature, high-pressure conditions, if relevant staff lack knowledge of production safety or operational errors, there will be a risk of serious physical injuries.

    6, injection molding involved peripheral equipment, auxiliary materials and tools more. Faced with injection molding machines, high-pressure mold clamping and peripheral equipment, high-temperature, high-speed, high-voltage environment and other safety hazards and more, if the injection workshop production safety management can not place a low safety awareness of staff of the posts , a little careless will be prone body bruised, burns, bruises, scratches metal, fire and electric shock accident.

    7, injection molding production process used in raw materials, packaging materials, materials outlet, plastic pieces, liquefied petroleum gas and various sprays are flammable, explosive materials, easy to produce fire.

    8, the following are not allowed to put the barrel of the machine thimble oil, mold release agents, rust inhibitors, prone to explosion wounding.

    9, the machine not to do cleaning work inside the machine during production.

    Injection Machining major risk factors:

    1, the main danger zone injection molding machine

    Injection molding machine is working at a fast powerful, high-speed, high-temperature, high-pressure conditions, the injection mechanism belong to high pressure, high speed and high temperature of the local machine.

    Injection molding machine main danger zones are as follows:

    (1) feed zone: This area is due to rotation of the screw, so do not be put into an iron rod or other foreign matter;

    (2) Tube cover area: This area is for raw materials heating zone, extreme temperatures and the risk of electric shock;

    (3) the nozzle area: This area of ​​high pressure injection of the raw material at a risk of splashing;

    (4) the mold area: This area is for the mold at high speed and high voltage switching area, very dangerous. In addition, the raw materials may also die from the mold surface discharge, be extremely careful;

    (5) Ejector zone: a strong mechanical action, be extremely careful;

    (6) clamping mechanism: a fast and strong mechanical action, be extremely careful.

    2, the main risk factors of harmful

    ① mechanical risk factors; ② Thermal damage factors;

    ③ electrical injury factors; ④ harmful substances;

    ⑤ environmental factors; ⑥ human unsafe behavior factors

    Hazardous Factors, injection molding machine peripherals

    1, hot air hopper dryer; 2, automatic packing machine;

    3, takeout machine (robot); 4, plastic crusher.

    Injection molding machinery processing operations accidents:

    Because of the strong, high-speed, high-temperature, high-pressure injection molding machines feature work. Security used in the design are usually higher, mostly accidents or operational errors caused by mishandling. Accidents often occur in the following circumstances:

    (1) hand was crushed mold;

    (2) hand was crushed thimble;

    (3) Due to troubleshoot or repair needs of the human head, arms into the danger area, but because there is no power cut injection molding machines, injection molding machine is not turned off the motor, equipment failure and sudden movements, resulting in certain parts of the body integrity were crushed;

    (4) high-temperature melt splash;

    (5) injection molding machine peripherals fire accident caused by crushing, burns, bruises, scratches and other metals.
