Problems solved by technology

[0002] When opening an injection mold with a large side core and a latent gate, it is necessary to compensate for the ejection gap caused by the side core coming out and cut off the latent gate before ejecting the plastic part. Starting to design the ejection mechanism three times, this undoubtedly increases the complexity of the mold structure, and also brings difficulties to the use and maintenance of the injection mold

Abstract

The invention discloses a triple ejection mechanism for an injection mold. The triple ejection mechanism for the injection mold comprises a movable mold seat plate, a cushion block, a movable mold plate and a fixed mold plate which are arranged from bottom to top. A pouring gate is arranged between the movable mold plate and the fixed mold plate. A movable mold insert and a fixed mold insert are arranged between the movable mold plate and the fixed mold plate. Side mold cores and mold cavities for formation of plastic parts are arranged between the movable mold insert and the fixed mold insert. A lower push plate, an upper push plate fixing plate and an upper push plate are arranged in the middle of the upper portion of the movable mold seat plate from bottom to top. Ejector rods and differential ejector rods are arranged on the upper push plate fixing plate. The upper push plate is provided with an upper reset rod. The lower push plate is provided with a lower reset rod and a pouring gate ejector rod which is connected with the pouring gate. The triple ejection mechanism for the injection mold is simple in structure, short in machining and assembly periods, easy to maintain and good in ejection effect.

Description

technical field [0001] The invention relates to the design field of injection mold ejection mechanisms, in particular to a three-time ejection mechanism for injection molds. Background technique [0002] When opening an injection mold with a large side core and a latent gate, it is necessary to compensate for the ejection gap caused by the side core coming out and cut off the latent gate before ejecting the plastic part. Starting to design the ejection mechanism three times, this undoubtedly increases the complexity of the mold structure, and also brings difficulties to the use and maintenance of the injection mold. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-time ejection mechanism for injection molds, which uses a mixed arrangement of differential ejector pins, sprue ejector pins and ordinary ejector pins to accurately realize three-time ejection actions , effectively guarantee the production effic...
