The invention discloses an accelerated descending inclined ejection pin for an injection mold of a rearview mirror shell. The accelerated descending inclined ejection pin for the injection mold of the rearview mirror shell comprises a front mold panel, a front mold plate, a rear mold plate, mold feet and a bottom plate, wherein the front mold panel is fixedly mounted on one side of the front mold plate, a front mold core is arranged in the front mold plate, the rear mold plate is fixedly connected with the bottom plate through the mold feet, a rear mold core is arranged in the rear mold plate, the two mold feet are arranged at an interval, an ejector pin plate is arranged between the mold feet, the ejector pin plate comprises an ejector pin panel and an ejector pin bottom plate which are fixedly connected, and the ejector pin plate further comprises an accelerated descending inclined ejection device, and the ejector pin plate is driven by an oil cylinder to move. The accelerated descending inclined ejection pin for the injection mold of the rearview mirror shell has the advantages of being good in stability, small in abrasion and long in service life of the mold.
Description
technical field [0001] The invention relates to the technical field of injection molds, in particular to an accelerating downward inclined roof for injection molds of rearview mirror housings. Background technique [0002] The rearview mirror shell is obtained by injection molding, which specifically means that the heated and melted plastic is injected into the mold cavity by the injection molding machine under high pressure, and after cooling and solidifying, it is ejected to obtain a molded product. [0003] When the current mold is demolded, due to the limitation of the product structure, the rearview mirror housing is ejected by using the inclined ejector rod, but the end of the inclined ejector rod and the rearview mirror housing will be worn, and even the movement will be stuck, which seriously affects the The quality of rearview mirror housing affects production efficiency. Contents of the invention [0004] Aiming at the deficiencies of the above-mentioned prior a...
