The invention discloses an injection mold of an integrated
plug in the technical field of injection molds. The injection mold comprises an ejector pin plate, an ejector pin, a first ejector sleeve, a second ejector sleeve, a push rod, a first elastic
rubber mat, a second elastic
rubber mat, a panel, a runner plate, a front mold plate, a rear mold plate, a square iron block and a bottom plate, a front mold core is fixed on the front mold plate, a rear mold core is fixed on the rear mold plate, and the front mold core and the rear mold core are oppositely arranged and form a cavity; the second ejector sleeve is arranged on the outer side of the first ejector sleeve in a sleeving mode, the push rod is arranged in the first ejector sleeve in a sleeving mode, the bottom end of the second ejector sleeve abuts against the second elastic
rubber mat, and the bottom end of the first ejector sleeve abuts against the first elastic rubber mat; a protrusion is arranged on the periphery of the upper portion of the second ejector sleeve. During injection molding, the bounce of the first elastic rubber mat and the second elastic rubber mat enables the protrusions of the first ejector sleeve and the second ejector sleeve to be pressed upwards at the corresponding positions of the
metal piece, so that the corresponding end faces of the
metal piece cannot be blocked and covered by injection molding rubber, the injection molding quality of products is guaranteed, and the yield of the products is improved.
