Analysis of mold failure factors in stamping mold production

   Mold failure is the most common problem in stamping mold production, often causing production downtime and affecting the product production cycle. Mold damage refers to the cracking, breakage, expansion, etc. of the mold. To deal with mold damage, it is necessary to find the cause from the design, manufacturing process, and use of the mold. Therefore, it is necessary to quickly identify the cause of the mold malfunction and carry out reasonable repairs.

   Firstly, it is necessary to review whether the manufacturing materials of the mold are suitable and whether the corresponding hot burial process is reasonable. Usually, the heat treatment process of mold materials has a significant impact on them. If the quenching temperature of the mold is too high, the quenching method and time are unreasonable, and the tempering frequency, temperature, and elbow spacing are not selected properly, it will all lead to damage of the mold after entering the stamping production. Insufficient size or depth design of the feeding hole can easily block the slot and cause damage to the feeding plate.

   If the spring force design is too small or the height of the sleeve is not equal, it will cause the spring to break and the feeding plate to tilt Causing overlapping impact and damaging parts. Improper fixation of the punch or insufficient screw strength It can cause the punch to fall or break. When using the mold, there may be installation errors in the position and direction of the parts or poor bolt tightening.

   The working height adjustment is too low and the guide column lubrication is insufficient. Malfunctions in the feeding equipment and abnormalities in the press can cause damage to the mold. If foreign objects enter the mold, parts overlap, waste blockages, and other situations are not dealt with in a timely manner and continue processing and production, it is easy to damage the falling plate, punch, lower template, and guide column of the mold.
