1. Before the mold is installed and used, it should be strictly inspected to remove dirt and check whether the mold guide sleeve and the mold are well lubricated. 2. Check the turntable and die mounting seat of the punch regularly to ensure the coaxial accuracy of the upper and lower turntable. 3. Install the punch and the die on the turntable according to the installation procedure of the die, so as to ensure that the direction of the punch and the die is consistent, especially if there is a direction requirement. Non-circular and square? Mold should be carefully installed to prevent errors and reverse installation. 4. After the mold is installed, check whether the fastening screws of the mold installation base are correctly locked. 5. When the cutting edges of the punch and die of the stamping die are worn, the machine should be stopped in time for grinding, otherwise, the wear degree of the cutting edge of the stamping die will expand rapidly, the wear of the die will be accelerated, and the quality of stamping parts and the service life of the die will be reduced. 6, for mass production of general mold, should have a spare, in order to rotate production, to ensure the production needs. 7. Should stamping personnel use soft metal when installing dies? Such as copper, aluminum, etc? Make operating tools to prevent damage to the mold when knocking or crushing during installation. 8. Handle the mold carefully during transportation, and don't throw it around, so as not to damage the cutting edge and guide rail of the mold. 9. After use, the mold should be put back to the designated position in time, and it should be oiled and rusted. 10. In order to ensure the service life of the mold, the spring of the mold should be replaced regularly to prevent the fatigue damage of the spring from affecting the use of the mold.
