摘要： An injection-molding machine has a fixed and a movable outer platen bracketing a movable intermediate platen, the latter having a runner system conducted via an extensible or flexible conduit to a source of molten plastic material to be injected into cavities defined by respective pairs of mold portions supported by the three platens, the cavities being formed in part by cores carried on the outer mold portions. A stripper plate inserted between each pair of mold portions is articulated via a spring-loaded lost-motion link to a respective eccentric pin on a pinion which is rotatably mounted on the intermediate platen and meshes with a pair of racks respectively secured to the two outer platens; this linkage is duplicated on opposite sides of the mold. In an initial phase of a mold-opening stroke, the stripper plates move outwardly under spring pressure while remaining in contact with their respective outer mold portions whose cores still retain the freshly molded articles. When the limit of the lost-motion travel is reached, the stripper plates are slowly lifted off their adjoining mold portions to detach the molded articles from the cores.

摘要： A fixed frame portion of an injection-molding machine carrier behind its movable platen a crank to which, at points approximately equispaced from its fulcrum, a pair of arms are articulated. One of these arms is pivoted to the movable platen whereas the other one is pivoted to a carrier connected with a set of ejector pins or a stripper plate. The spacing of the points of articulation of the two arms on the crank is so chosen that the separation of these points in the direction of platen motion is relatively wide in one limiting position and relatively narrow in the other limiting position of platen reciprocation whereby the carrier is thrust forward with reference to the platen as the latter is retracted.

摘要： An ejector assembly for removing a molded part from a mold includes an ejector arm and mounting structure. The ejector arm has a first end with a tongue that extends partially into a cavity of the mold and an opposite second end with a handle that extends outwardly from the mold cavity. The mounting structure pivotally mounts the ejector arm to the top portion of the mold so that the ejector arm may be pivoted between an operating position and an ejection position.

摘要： A tooling for injection-molding a part, the tooling including two cavity blocks each including a cavity formed therein of a shape corresponding to a shape of a part that is to be molded once the cavity blocks have been superposed, at least one of the cavity blocks including an ejection mechanism ejecting the molded part and including at least one ejector movable between a molding position and an ejection position. The ejector is guided to move between its two positions along a curved path, or a circular arc, of shape that corresponds to a shape of a portion of the mold part to be extracted from the cavity.
