        The occurrence of mold deformation in mold processing refers to the excessive elastic deformation or plastic deformation of the mold in the work project, which makes the mold unable to work normally or the product quality unqualified. The causes and troubleshooting are as follows.
        Insufficient rigidity
        In the process of injection molding, the mold bears great pressure. If this pressure causes permanent deformation of the die, the die will not be used, but the deformation generated by the die can be recovered even within the elastic limit. The solidification and molding of the mold will make the opening of the mold difficult or even impossible. In this case, the structure of the mold cannot be modified, but the injection pressure can be appropriately reduced or a frame can be added from the outside to enhance the rigidity. Although it doesn't look good, it's also used.
        Mold assembly dislocation
        If the mold is not assembled properly, such as poor alignment of the mold, inaccurate alignment of the clamping part and its joint, resulting in unbalanced melt filling, which is easy to cause mold deformation or dislocation. In this regard, the mold should be reassembled. Sometimes the mold filling imbalance can be corrected by correcting the gate.
        The correct use and maintenance of molds is a major factor in improving the quality of molds. For example, the installation and commissioning method of the mold should be appropriate. When there is a hot runner, the power wiring should be correct, the cooling water circuit should meet the design requirements, the parameters of the injection molding machine, and the die casting machine and press in the process of mold manufacturing should meet the design requirements.
        Jinan injection molding workers believe that while using the mold correctly, they also need to maintain the mold regularly. The parts with relative movement with the die such as guide post and guide sleeve shall be filled with lubricating oil frequently. For forging dies, plastic dies, die-casting dies and other dies, lubricant or release agent shall be sprayed on the surface of the formed parts before forming.
        Therefore, the mold design should be considered comprehensively, including the selection of mold materials, the usability and safety of mold structure, the machinability of mold parts and the convenience of mold maintenance. These should be taken into account in the design to weigh the comprehensive performance and greatly reduce the favorable factors.
