    Abstract: An injection molding apparatus is used for making parts having a hollow portion that is disposed under an angle relative to an axis. The molded parts are ejected when a movable stripper plate is displaced relative to the mold core used to cool the angled portion of the molded part. The stripper plate includes cooling channels and a cooling outlet. The cooling outlet is coupled to a cooling inlet of a movable cooling slider element. Leakage of a cooling fluid is prevented by using a sealing device and sealing elements between the cooling slider and a cooling manifold retaining the mold cores when the stripper plate is used during the ejection of the molded parts from the mold cores.

    Abstract: At the filling station of a dry cast pipe making machine for making pipe lined with a plastic liner, the liner is first placed over the core and then a plurality of spaced-apart, removable L-shaped plates are secured around the top edge of the core. One leg of each plate extends inside the core with the other leg extending downwardly over the top edge of the liner. The plates are removably held in place on the core by the use of a clamping device, such as a vise-grip, for example. Once the form is filled with concrete and ready for the pressure heading step, the downwardly extending legs of the plates serve as ‘shoehorns’ to guide the pressure header over the top of the liner and prevent damage to it. In addition, the plates will assist in centering the core within the jacket.

    Abstract: During injection molding of a thin-wall plastic product, such as a drink cup, the formation of void-based irregularities is prevented in a thin-wall portion of the product formed within a zone of a thin-wall cavity section that is located between adjoining flow chambers, in which zone the thickness of the thin-wall cavity section increases in the general direction of flow within the flow chambers adjoining such zone. Such void-based irregularity formation is prevented by dimensioning the mold cavity so that the thickness increases in such direction at less than a threshold rate. The flow chambers do not extend to a rim portion of the thin-wall cavity section; and the respective inscribed-sphere dimensions of the adjoining flow chambers within a terminal zone of the thin-wall cavity section adjacent a rim portion of the mold cavity are less than the respective inscribed-sphere dimensions of upstream portions of the adjoining flow chambers.

Generally, the walls of the mold are attached to the base with a pivoting assembly such that the walls of the mold fall away from the molded material after hardening. Levers and fulcrums of various designs are used to facilitate the mold wall movements. Additionally, quick release and tightening mechanisms are used to secure the mold walls. Also, the wall of the mold can be designed to incorporate patterns such that the blocks formed in the molds can interlock when stacked, forming a very sturdy wall. Further, specially designed inserts can be utilized to quickly modify the mold.

  • Patent number: 5755982
    Abstract: A mold system for casting five-sided, monolithic, seamless concrete products comprises an outside jacket, an inside mold core complete with base, and a movable pallet to aid stripping. The outside jacket preferably includes two L-shaped panel members arranged in a rectangular configuration which are supported for movement between open and closed positions by a pair of base-mounted corner actuators extending from the fixed base to the apex of each panel member. The panel members are also linked to one another by a series of actuators along each of the adjoining two corners of the jacket. The inside core includes four interior panels linked by four inside retractable corners. A minimum of two series of actuators also span the middle portion of the inside core. These middle actuators in conjunction with the actuators in the corner devices function to expand and contract the entire inside mold core. A plurality of base supported actuators are fastened to the inside core.

  • Patent number: 5511762
    Abstract: A method of manufacturing an open top, walled member for containing a molten metal, including the steps of forming an inner wall of a mold with a metal sheet and an inner lining covering the sheet, wherein the inner wall defines an inside surface of the walled member and transferring a casting compound between an outer wall of the mold and the inner lining of the inner wall to form the walled member. The metal sheet and inner lining are then removed to allow one to apply heat to dry the casting compound. In the case where the metal sheet includes a plurality of openings, one may also retain the inner wall during the heating step. The heat to dry the casting compound is applied to the inner lining to a sufficient temperature to melt the inner lining and uncover said openings of the metal sheet. The metal sheet is removed when the casting compound is dried.

  • Patent number: 5505893
    Abstract: A method of manufacturing an open top, walled member for containing a molten metal, especially a flowing molten metal or reconstructing a worn or damaged member. The method includes the step of forming the inner walls of a mold which define the inner surfaces of the walled member of an open metal mesh screen which is meltable by the molten metal which is to be contained. The next step is to transfer, usually by pumping, an alumina-silicon carbide casting compound into the space between the open mesh metal screen and the outer walls defining the mold, which outer walls may be in situ structures. If an existing walled member is being repaired, any damaged or worn portions of the existing walled member are removed and the casting compound is poured in to replace these portions. The next step is to apply heat to dry the casting compound while the open mesh screen of the mold remains in place in contact with the casting compound.

  • Patent number: 5496008
    Abstract: An apparatus for molding experimental, prototype and replacement parts from rubber materials. The apparatus consists of a mold having walls made from layers of fiberglass cloth and laminating resin reinforced with a mixture of quartz sand and laminating resin; a frangible cellular core made of a two component system polyurethane foam core and a hard outer coating of a quick set resin; a wax; and a release agent. The frangible core is formed by coating the surfaces of a core forming cavity of a core box with the wax to fill in irregularities; buffing the wax coating to provide a smooth finish; applying the release agent over the wax; coating the release agent with the hard quick set resin; and filling the core forming cavity with the two component system polyurethane foam. The frangible core is inserted in the mold, a rubber polymer is injected into the mold and the frangible core is removed from the part by breaking the core into small pieces after the part is removed from the mold.

  • Patent number: 5439370
    Abstract: A device for molding plastics material ferrules for optical fiber connectors comprises a molding cavity defined by an accurately sized cylindrical bush defining the outside diameter of the ferrule. A cover closes the molding cavity. A peg joined to the cover extends axially into the molding cavity and is extended at its free end by an accurately sized needle defining the inside diameter of the ferrule. A backing member extending axially into the molding cavity from the opposite end as compared with the peg comprises a bore for guiding the needle adapted to receive the end thereof when the backing member moves towards the peg so as to render the needle and the bush concentric. A venting system allows gases to escape from the molding cavity to the exterior when plastics material is injected into the mold. The backing member is a substantially cylindrical body of revolution which fits directly into the bush with no clearance and minimal force.

  • Patent number: 5400698
    Abstract: A cup-shaped mold for the shaping and baking of bread, batter, cookie dough and other baking material comprises an upper cupped molding member and a lower, slightly larger, cupped molding member. The molding members are made from materials with different coefficients of heat transfer to create a heat differential while cooking. The molding members are placed together with the baking material between them, thereby forming the baking material into a cup-shape. During heating of the mold for baking, a plurality of springs or clamps press the molding members together at between about 0.5 and 1.0 p.s.i. to prevent escape of the baking material from the mold while allowing partial escape of moisture from the mold.
