Mold injection molding - the punch should be noted before use

Mold injection molding - the punch should be noted before use
1. Storage

(1) Wipe the inside and outside of the upper mold with a clean rag.

(2) Be careful not to have scratches or dents on the surface when storing.

(3) oil rust prevention.

2. Preparation before use

(1) Clean the upper mold cover thoroughly before use.

(2) Check the surface for scratches and dents. If present, remove with a stone.

(3) Oil inside and outside.


3. Precautions should be taken when installing the punch on the upper die sleeve

(1) Clean the punch and oil its long handle.

(2) Insert the punch into the bottom of the upper die sleeve on the large station mold, and do not force. Don't use a nylon hammer. During installation, the punch cannot be fixed by tightening the bolt on the upper die sleeve, and the bolt can only be tightened after the punch is correctly positioned.


4. Install the upper die combination into the turret

If you want to extend the service life of the die, the gap between the outer diameter of the upper die sleeve and the turret hole should be as small as possible. So please be careful with the following procedures.

(1) Clean and oil the keyway and inner diameter of the turret hole.

(2) Adjust the keyway of the upper die guide sleeve to match the key of the turret hole.

(3) Insert the upper die guide straight into the tower hole, careful not to have any tilt. The upper die guide sleeve should slide into the turret hole under its own weight.

(4) If the upper die sleeve is tilted to one side, a soft material tool such as a nylon hammer can be used to gently knock it straight. Repeat the tap until the upper guide slips into the correct position under its own weight.

Note: Do not force on the outer diameter of the upper die guide sleeve, only force on the top of the punch. Do not hit the top of the upper die sleeve, so as not to damage the turret hole and shorten the service life of individual stations.
