Abstract：In view of the difficult core pulling caused by the complex structure of the rereading mechine surface shell plastic part, the oblique pin and inclined slider were used to pull the core together, the ejector insert spring core pulling was ejected, and the inclined top core pulling structure was used, and good results were obtained. At the same time, the secondary gate was used to feed the material from the middle of the plastic part, avoiding the problems of fusion mark and lack of plastic; the push tube, push rod and inclined top are designed to eject the plastic part smoothly.
