When the injection molding machine opens the mold? ? What's wrong with the big ring and the machine vibration? The expert who has done this problem gives me some advice. Come and go, please be more specific.
It should be that the elbow copper sleeve is worn too much, or the linear limit has changed. After clamping, the elbow is not in a straight position, but not in the opposite direction [like a person's elbow turning backwards]
When the product is injected, because it is reversed, it is necessary to pull the elbow from the reversed position to the straight position to open the mold, which requires a lot of mold opening force and will produce a lot of noise.
