Automobile plastic part injection mold and side slide ejection mechanism thereof

Abstract

The application discloses a kind of automobile plastic injection mould and its side slide ejection mechanism, including the forming block of lower mould sliding and the forming piece connected on ejector rod.Forming area is equipped with the convex column of forming bottom hole, and the receiving cavity is equipped in the inside of forming piece, and connecting rod and tap are slidably connected in receiving cavity.Forming piece is equipped with the sliding slot and gate connected with receiving cavity.When clamping, forming block drives gate to close receiving cavity by connecting mechanism, and convex column is tightly closed to gate to physically seal glue;When opening, forming block retreats to make gate open, and connecting rod is driven to rotate while advancing into bottom hole by transmission assembly and rotating mechanism, so that tap is threaded.The application realizes automatic sealing glue and pure mechanical linkage of tapping in mould by opening side sliding action, effectively prevents plastic melt backflow, and improves the processing precision and production efficiency of transverse thread hole.
