Abstract: An injection molding press apparatus for use with a variety of different interchangeable molding tools that allows the simultaneous molding of different parts. The interchangeable molding tools are custom designed to form a desired part. Each interchangeable molding tool allows for the easy replacement of different types of molding tools for the molding of different parts without the need of an entire mold replacement. A preferred embodiment of the invention comprises a baffle sorting system for injection molding machines thereby increasing the allowing the simultaneously molded different parts to be ejected from the machine without the need of separating the different parts. This increases the speed of each production run.

Abstract: An injection molding apparatus having an A side and a B side for use with interchangeable molding tools that allow the center gating of a part. Center gating directly into a molding tool provides a uniformly stress resistant cylindrical part. The use of interchangeable molding tools provides easy replacement of tools that are designed to produce a variety of different parts. Each interchangeable molding tool provides a runner tool distribution system to allow injected material to enter directly into the center of a part to be molded. Once the part is molded, the runner that is formed in the runner tool distribution system is separated from the molded part. The molded parts are then simultaneously released from the mold assembly.

Abstract: A water jacket assembly for use in injection mold systems, and particularly with heterocavity injection mold systems. The water jacket assembly comprises a sleeve construction of material with high heat-transfer properties. A conduit is beveled into the outside perimeter of the sleeve forming a circulation channel. The inside perimeter of the sleeve is fashioned to receive an individual injection mold. A mold base slideably received the water jacket and cooling fluid is circulated from the mold base through circulation channel in the water jacket, and then back to the mold base. A fluid input plug and fluid output plug extend from the mold base and are received by the apertures in the individual mold for additional cooling.

Abstract: A baffle sorting system for use with injection mold machines that produce different mold products from a plurality of mold cavities during the same production run whereby at least one baffle extends perpendicular to one plate in a mold between two mold cavities, and corresponding slot on the second plate of a mold receives the baffle when both plates are coupled. When the product is ready to be ejected from the machine, both plates separate, but the baffle prevents the products of one mold from intermingling with the products of a second mold. The products drop down into a collection device for further processing or packaging. Alternatively, the baffles are positioned between the A plate and the B plate during the ejection phase of the molding cycle, then retracted from the mold machine during the injection phase.

Abstract: A modular mold assembly for use in injection molding and method of use. The modular mold assembly comprises a fixed side and an ejector side and a plurality of interchangeable modules for shaping a plurality of sides of a component attached to the mold assembly. The modules include blank modules and slide modules. The interchangeable modules are attached to the mold assembly by slide retainers attached along an interior surface of the ejector side. Slide actuators are attached to the fixed side for engaging the slide modules. The slide actuators move the slide modules inward when the mold halves are pressed together forming a mold cavity and move the slide modules outward when the mold halves are separated.

Abstract: A device for exercising a living hinge of an article and/or closing a lid of a cap while the article or cap is in a mold for forming the article or cap. The device includes a finger which slides between the mold sections, and, in the process, engages a portion of the article or the lid, rotates the portion or lid about the hinge, and in the case of the cap, snaps the lid shut. In an alternate preferred embodiment, when the finger reaches predetermined point it pivots toward the female mold section to snap the lid tightly shut.
