A button die is a die that is nested in the lower die plate of a mold.
Normally, the lower die plate is used and the surface of the plate is polished by maintenance. Therefore, the thickness of the plate becomes thinner. In addition, the removal of the lower die plate is a time-consuming operation.
The button die is a nested type, so only the button die needs to be removed for maintenance. This is a simplified maintenance method. Since only the button die can be polished and replaced when it reaches the end of its service life, it can be used for a long period of time.
Button dies are easy to maintain because they are nested. The button dies are the part that corresponds to the blade in a pair of scissors.
The button dies alone do not function. A punch (the blade's counterpart) is also required.
The button dies are the lower blade and the punch is the upper blade. The upper and lower blades can process holes in the product.
Repeated hole drilling causes the blades to wear, requiring grinding.
Grinding can be performed by removing the button dies from the lower die. It can then be used by fitting it back into the lower die.
Due to their nested nature, they have a long service life and are easy to remove for maintenance.
Button dies need to be quenched as a measure against wear since they are part of the blade. Without hardening, wear progresses quickly and the purpose of extending service life cannot be achieved.
The lower die can be left as it is without quenching.
The button dies are the part that becomes the blade, so it can be processed when a punch is inserted. At that time, it is necessary to penetrate the die so that the shavings cut by the punch will fall to the bottom. This is the countermeasure against hole jamming.
Failure to take countermeasures against hole jams will result in the punch breaking and damaging the product.
Next, it is also necessary to take measures to prevent the button dies from generating shavings. It is necessary to prevent shavings from falling out of the button dies as the shavings will be blown out from the surface of the button dies after processing. If the die is processed with the scum floating on the surface, the dents will be transferred to the product, resulting in defective products.
