Precision injection mold is an important tool in the production of injection molding parts, and many factors affect the precision and quality of injection parts. The following are the precision injection mold factors summarized by the engineers of Enuo Mold injection mold factory have an important influence on the precision of injection parts.
1、 The accuracy of injection mold; the accuracy of injection mold mainly depends on the accuracy of mold cavity size, the accuracy of cavity position or the accuracy of classification surface meets the design requirements. The dimensional tolerance of ordinary precision injection mold shall be controlled within 1 / 3 of the product dimensional tolerance.
2、Processability and rigidity of precision injection mold; in the structure design of the mold, the number of cavities should not be too much, and the bottom plate, support plate and cavity wall should be as thick as possible to avoid elastic deformation of products under high temperature and high pressure.
3、mold release of products; precision injection mold should be used as few as possible, less and short flow channel, and high finish, which is conducive to mold release.
4、Processing materials for precision injection molding; steel with high mechanical strength. The material of making cavity and pouring channel should pass strict heat treatment, and the material selection should have high hardness, good wear resistance and strong corrosion resistance.
