Jun 11, 2018

Core Tips: Several points should be noted in the injection mold up and down mold one. The preparation of the upper mold two. The upper mold step three. The preparation of the lower mold

 A. The preparation of the mold


1) First check whether the material is baked or not. If it is not baked, it must be baked first.


2) Check whether the machine is empty, whether the size of the machine is appropriate, whether the ejection is appropriate, and whether the required special function is available. If there is not enough, the report will be reported immediately.


3) Check whether the mold is good. If it is not good, it will immediately report the waiting notice.


4) The above three points are all ready to be ready for tooling, plumbing and corresponding equipment.


Two mold step


1) Pull the mold to the front of the appropriate machine and place the corresponding eyebolt and confirm the ejector pin.



Use a crane to lift the mold slowly and place it into the machine to align the positioning ring of the machine and the mold.


3) Slowly close the mold and tighten the mold.



Use a pressure plate to fasten the mold and slowly loosen the crane and remove the crane, and lift the palladium again.


5) Apply high pressure and tighten the screw again and hold the nozzle.



First check that the mold has no abnormalities or equipment to be opened before mold opening. After confirming the mold, slow mold opening.


7) After mold opening, check mold for abnormality again.


8) Find related personnel to access special auxiliary equipment and debug it.



According to the requirements, install auxiliary equipment such as water, forced pull, hot runner, etc. and test whether these auxiliary equipment are normal.


10) Ready to boot.



III. Preparations for Die


1) Stop the injection molding and eject the screw residue to clean the screw with PP material.


2) Close the appropriate water: normal water and mold warmer water.



Prepare well and prepare the tools and the corresponding equipment: buckets, air guns, anti-rust oil, rings, cranes and so on.


4) Find the appropriate department to remove the equipment to be removed before the lower die.
