Injection molding mold with cylindrical vertical glue injection port

Abstract

The utility model relates to the technical field of injection molding, in particular to an injection molding mold with a cylindrical vertical glue injection port, which comprises an upper mold, a lower mold and a cylindrical molding mold core, the cylindrical molding mold core is arranged in the lower mold, and the upper mold and the lower mold can move oppositely or oppositely. The cylinder forming mold core comprises a head end positioning structure, a tail end positioning structure and a thread forming structure, and the head end positioning structure and the tail end positioning structure are both in an outward expansion shape. The problem that uneven thickness distribution is easily caused when an existing cylindrical thin-wall product is machined is effectively solved; according to the utility model, the pouring channel perpendicular to the injection molding space is used for molding a cylindrical product, and meanwhile, a cylindrical thin-wall workpiece is molded under the combined action of the head end positioning column, the injection molding space and the tail end positioning structure; under the action of the forming mode, the formed thin-wall workpiece is higher in strength and more uniform in wall thickness.
