Water leakage in plastic injection molds typically arises from the following situations:
Leakage at cooling water pipe joints in injection molds:Upon discovering leakage, first wrap sealing tape around the threads of the water pipe joints and tighten them securely to restore sealing.
Water leakage due to aging or improper installation of waterproof rings:Due to the long-term operation of injection molds under harsh conditions, the internal waterproof rings may fail due to aging, hardening, or cracking. Additionally, improper installation of waterproof rings can also lead to sealing issues. Therefore, it is necessary to regularly check the installation position and sealing performance of the sealing rings, replace damaged or aged waterproof rings in a timely manner, and ensure their correct installation.
Damage to cooling water holes in injection molds:Despite sufficient wall thickness during design, processing errors or subsequent handling may result in punctured hole walls. This requires careful inspection of the mold to promptly detect and repair damaged cooling water holes.
Maintenance and care of cooling water holes:Cooling water holes are prone to scaling, which affects heat transfer and may severely block water flow. Therefore, regular cleaning and maintenance of cooling water holes are essential to ensure their unobstructed flow.
Compared to other molds, injection molds have a more complex and precise structure, requiring higher standards for operation and maintenance. In the injection molding process, proper usage methods and meticulous maintenance and care are crucial for ensuring efficient and stable production in enterprises.
