In the case of guaranteed spring travel, the length of the guide should be greater than 1/2 of the free length of the selected spring. The installation of the spring and the upper and lower mounting faces of the replacement mold spring must be parallel to each other. The front end of the self-shaft and the mouth of the socket should be chamfered, and the root of the hole should be prevented from leaving a large chamfer. When the mold spring is repaired and replaced, only one or a few springs are replaced, and the old and new springs are mixed, which causes the unevenness of the spring bearing load to cause the spring with large load to fail early. It is necessary to prevent the inclusion of iron filings, scraps and other debris in the spring. The mixing of the debris is equivalent to reducing the effective number of turns of the spring, which causes high stress and damage of the spring. Therefore, the mold needs to be opened after one round of production. And clean up. Do not arbitrarily change or combine springs. The springs are designed and manufactured to the best performance. When the mold maintenance personnel repair the molds, the standard springs are modified due to the absence of suitable spring spare parts, such as cutting, grinding the inner and outer diameters or using springs in series. Neither can guarantee the characteristic value of the original spring, which will cause early failure of the spring.
