A special forming die for gear forgings that facilitates ejection.

Abstract

This utility model belongs to the field of forging mold technology, and particularly relates to a special forming mold for gear forgings that facilitates ejection. It includes a base, a lower mold fixedly mounted on the top of the base, an upper mold driven by a drive device and adapted to the lower mold, and a cooling device within the lower mold. A slider is movably connected to the outer side of the upper mold, and each slider is movably connected to a corresponding connecting rod. A connecting shaft is hinged to the end of the connecting rod away from the slider. An ejector rod is movably connected within the lower mold, and a horizontal plate parallel to the base is fixedly mounted at one end of the ejector rod extending into the lower mold. This special forming mold for gear forgings, which facilitates ejection, moves up and down within the lower mold through the cooperation of the ejector rod, slider, and connecting rod. Driven by the movement of the slider and connecting rod, it can evenly eject the formed gear forging, avoiding the surface damage to the forging and mold damage caused by uneven ejection force distribution in traditional molds.
