How to assemble injection mold ?

Since the structure of plastic molds is relatively complex and there are many types, the specific assembly process is formulated according to its structural characteristics.

Steps of mold assembly & fitting

  1. Determine the assembly benchmark. 
  2. Parts must be measured before assembly. Qualified parts must be demagnetized and wiped clean.
  3. The accumulated dimensional error after adjusting the combination of each part.
    For example, the parallelism of each template must be verified and ground to ensure that the template assembly is tight.
    The matching area at the parting surface shall not be less than 80%, and the gap shall not exceed the minimum value reported for overflow to prevent Flash occurs.
  4. During assembly, try to keep the reference plane of the original processing dimensions so that it can be checked during the final assembly mold closing adjustment.
  5. Assemble the guide system and ensure that the mold opening and closing movements are flexible and free of looseness and stagnation.
  6. Assemble the ejection system, and adjust the reset and ejection positions.

7. Assemble the core and inserts to ensure that the matching clearance meets the requirements.

8. Ensuring that the cooling or heating system is assembled correctly to maintain smooth pipelines. No water leakage, no electricity leakage, and flexible valve movements.

9. Assemble hydraulic or pneumatic systems to ensure normal operation tighten all connecting screws and assemble the positioning pins.

10. Finally, check various accessories and ensure that the mold is fully equipped with lifting rings and other parts for mold testing.
