  The inspection of injection molds is very important. The 20 points outlined below are intended to help you.

 

    1. The cooling inlet should be installed on the opposite side of the operator.

 

    2. Use a protective foot in the case of a cooling nozzle under the mold.

 

    3. The nozzle can not be installed on the wrench position.

 

    4. The inlet of the nozzle should be processed 1/4, 1/8 pipe thread

 

    5. The sealing ring installation position to stop processing.

 

    6. There must be no residual swarf at the inlet of the nozzle.

 

    7. Use a water test to confirm if there is a leak.

 

    8. Use blow air pressure test to confirm whether the water channel is open.

 

    9. Use a locking block on the three-plate mold to ensure safety.

 

    10. Install anti-rotation device on the point sprue bushing.

 

    11. Ensure that the Z opening is facing downward when using a Z-shaped puller.

 

    12. The length of the cold part of the runner is 2 times the diameter of the runner.

 

    13. Carve the name of the forming material on the runner.

 

    14. When there are 2 or more pullers, anti-rotation device should be installed.

 

    15. Slide rails should be made separately.

 

    16. Determine the slider stroke position, use the limit bolt and ball plug simultaneously.

 

    17. Limit bolts are available with hexagon socket bolts to prevent slack.

 

    18. Use a multimeter to confirm that the limit switch is ON and OFF.

 

    19. The positioning ring should be processed according to the requirements of the gold type book.

 

    20. The R at the entrance to the sprue should be machined in accordance with the requirements of the gold type book.
