What preparations need to be done before the rapid mold change of the injection molding machine?

1. Put on the safety helmet and prepare the wrench, anti-rust agent, rag and other mold removal tools.
2. Check the crane:
Check whether the crane action and the functions of each button are sound and normal. In particular, the emergency stop button should be tested. If there is any problem, it should be stopped immediately, and hang a "No Use" sign, and notify the shift leader to report for repair.
3. Check the wire rope and shackle:
Check whether the steel wire rope used has laps, broken strands, and whether the hanging die is overweight? Replace the wire rope immediately if any;
The shackles used for lifting shall not be bent or deformed, and shall not be inconsistent with the tonnage of the lifting mould.
4. Check the mold to be installed:
Select the machine that can be installed according to the layman size of the mold (generally, the machine is designated by the workshop plan, and there is no need to select it by yourself);
Whether the mold uses the core-pulling function. If yes, please prepare the oil pipe and oil pipe joint, and check them. Do not use it if the thread is found to be bad, so as to avoid damage to the good thread and oil leakage;
Check whether the cooling water pipe joint of the mold is installed properly and whether the water path is smooth (connect the air path for inspection);
Install the lifting ring (the bent lifting ring is not used). The depth of the lifting ring into the mold must be greater than 1.5 times the diameter of the lifting ring. If the lifting ring surface and the mold have not been attached, the gasket must be used to prevent the ring from bending and breaking.
