Specification for installation and adjustment of plastic molds

1. Mold pre-inspection:

Once the plastic mold is installed on the mold, it should be inspected to find out the quality problems in time, and the mold should be repaired to avoid removing the mold after being installed on the machine. Get it wrong.

2. Oblique guide die device:

When installing the mold, the two people should cooperate closely and pay attention to safety. If there is a mold with a lateral parting structure, the slider should be installed in a horizontal position, that is, the movable block moves left and right.

3. Mold tightening:

When the mold positioning ring is loaded into the positioning ring seat of the fixed template on the injection molding machine, close the mold at a very slow speed, so that the moving template presses the mold lightly, and then put on the pressing plate, and the pressing plate must be fitted with a pad It is necessary to install 4 pieces on the upper and lower sides of the pressing plate, and when putting the pressing plate on, it is necessary to pay attention to adjusting the height of the adjusting screw to the same height as the die foot, that is, the pressing plate should be flat. If the pressing plate is inclined, the die foot of the mold cannot be pressed very tightly. The side of the pressing plate should not be close to the mold to avoid friction damage to the mold.

4. Correct the ejection distance of the ejector rod:

After the mold is fastened, start the mold slowly until the moving platen stops retreating. This is the position of the ejector rod. The position of the ejector should be adjusted to leave a gap of not less than 5 mm between the ejector plate on the mold and the bottom plate of the moving mold to avoid damaging the mold, but can eject the part.

5. Adjustment of closed mold tightness:

In order to avoid overflow and ensure proper venting of the cavity, when adjusting the hydraulic injection plug-toggle clamping structure, it is mainly based on visual observation and experience, that is, when the mold is closed, the toggle is fast first and then slow, that is, it is not very natural. , and it is not stretched too reluctantly, and the tightness of the closed mold is just right. For molds that require mold temperature, the tightness of the mold should be corrected after the mold temperature is raised.

6. Connect the cooling water:

After connecting the cooling water, check whether it is unblocked or leaking.
