How is the injection molding machine debugged?

    Action procedure of injection molding machine: nozzle advance → injection → pressure maintaining → pre molding → shrinkage → nozzle retreat → cooling → mold opening → ejection → needle withdrawal → door opening → door closing → mold closing → nozzle advance. Small injection molding machine operation items: injection molding machine operation items include control keyboard operation, electrical control cabinet operation and hydraulic system operation. Manual operation is in a production cycle, each action is realized by the operator turning the operation switch.

    Basic principle of injection molding: the injection molding machine uses the property that the plastic can melt into liquid after heating to a certain temperature. The molten liquid is injected into the closed mold cavity with high pressure, cooled and shaped, and ejected after opening the mold to obtain the required plastic products. Four elements of injection molding: 1 Plastic mold 2 Injection molding machine 3 Plastic raw materials 4 Forming conditions. Most plastic molds use two plate molds, three plate molds, and some row position molds with sliding blocks. Basic structure: 1 Male mold (lower mold) male mold fixing plate, male mold auxiliary plate, thimble plate and male mold. 2. Female mold (upper mold) female mold, female mold fixing plate, rubber ring and positioning ring. 3. Constant temperature cooling system Stabilize (balance) the mold temperature.

    General steps for new machine commissioning of injection molding machine:

    1. Machine installation

    2. Machine level adjustment

    3. Connect the machine with electricity, water and oil

    4. Start the motor and check the reverse rotation of the motor

    5. Barrel heating temperature inspection

    6. Manually adjust the parameters to make the operation stable

    7. Semi automatic operation

    8. Moulded products
