【Summary Description】The function of mold springs is to remove materials, press materials, determine the magnitude of spring force, ensure smooth mold production, and ensure that the product is qualified.
The function of mold springs is to remove materials, press materials, determine the magnitude of spring force, ensure smooth mold production, and ensure that the product is qualified. Low spring force may cause various problems such as product deformation, mold failure to peel off, difficulty in removing the product from the mold, strip, blade, punch, etc.
According to different production times, the compression amount of the mold spring is relatively large. The shorter the spring life, the shorter the mold life. Of course, if the spring is broken, it can be replaced. However, the specifications of each spring are different, and the design has also been determined. Do not easily replace it during use. If the mold is produced for a period of time, the spring may become weak, and poor quality springs may break in the mold.
The compression amount of the mold spring is generally calculated at 300000 times. That is to say, the mold may not have enough force after 300000 uses. Of course, the lifespan of general stamping dies is not long, and the maximum compression amount can also be calculated. If the compression amount is calculated, it can only ensure that the spring will not explode inside the mold. Slightly pressing the mold is beneficial for the flatness of the product.
