Abstract
Top and bottom ferrous carrier plates have a plurality of pairs of mating window cavities. Pairs of mating nonferrous pre-molded inserts with mating mold cavities snap into mating window cavities with a rubberized retainer ring therebetween to create floating mating pre-molded insert molds in multiple material carrier plate assemblies. Liquefied material is dispensed through pot bushings and plungers in each top pre-molded insert. The liquefied material flows though gate openings located in each insert top surface filling the mold cavities. The liquefied material then solidifies to its permanent shape in the mold cavities.

A multiple material carrier plate assembly with mating pairs of three axis floating replaceable pre-molded inserts each having at least one mold cavity, inserted into window openings in two removable carrier plates for use in precision molding, the assembly comprising:
- a mating pair of removable carrier plates adapted to be installed in a precision molding device, each of the carrier plates having a mating matrix of elongated precision openings arranged in a given pattern and precision position for precision alignment of the mating pair of carrier plates, the carrier plates having at least one pair of window openings, with one of the window openings in each of the mating carrier plates, adapted for aligning with the other mating window opening when the carrier plates are moved together in a molding process, the carrier plates fabricated of a ferrous material adapted for long-term use in a production precision molding apparatus, each of the window openings having a continuous recessed groove in an interior edge of the window opening around the entire window opening;
- at least one pair of replaceable pre-molded inserts each having at least one mold cavity, each adapted to be inserted in one of the pair of mating window openings to secure each of the pre-molded inserts within one of the mating window openings of the carrier plate, each of the pre-molded inserts having a continuous groove around an entire outside perimeter edge and each of the pre-molded inserts having at least one mold cavity;
- the mating pair of pre-molded inserts further comprising a plurality of pairs of mating alignment elements adapted for automatically lining up the pair mating pre-molded inserts precisely during a precision molding process, the mating pre-molded inserts fabricated of a nonferrous moldable material adapted for withstanding operating temperatures and compression pressure required for a production precision molding process;
- a resilient rubber-like preformed retainer ring stretched around each of the pre-molded inserts perimeter edge and each tension fit into the continuous groove encircling the perimeter edge with a portion of the retainer ring extending outside of the perimeter edge of the pre-molded insert, so that each insert is adapted to be inserted into one of the window openings with the retainer ring snapping into the recessed groove around the window opening so that the pre-molded insert is adapted to be insertable, removable and replaceable, the retainer ring having a resilience sufficient to allow motion of the insert in an X axis, Y axis and Z axis thereby forming a three-axis floating mold, the mating pre-molded inserts being adapted to be moved together into a mating position in a precision molding process, the retainer ring fabricated of a nonferrous rubberlike material adapted for withstanding the operating temperatures required for production precision molding;
- thereby forming a multiple material carrier plate assembly with mating pairs of three axis floating replaceable pre-molded inserts each having at least one mold cavity, inserted into window openings in two removable carrier plates for use in precision molding.
A multiple material carrier plate assembly molding method using mating pairs of three axis floating replaceable pre-molded inserts attached to window openings in pairs of removable carrier plates, each pre-molded insert having at least one mold cavity, the method comprising:
- a first step of fabricating at least one pair of removable carrier plates of a ferrous material adapted for long-term use in a production precision molding machine, each of the pair of carrier plates having a mating matrix of elongated precision openings arranged in a given pattern and precision position for precision alignment of the mating pair of carrier plates, the at least one pair of carrier plates having at least one pair of mating window openings, having one of the mating pair of window openings in each carrier plate, the pair of mating window openings mutually aligning when the carrier plates are moved together in a molding process, each of the window openings having a continuous recessed groove in an interior edge of the window opening around the entire window opening;
- a second step of pre-molding at least one pair of replaceable mating pre-molded inserts having mating mold cavities, each of the pre-molded inserts having a continuous edge groove around an entire perimeter of each of the pre-molded inserts, each of the mating pair of pre-molded inserts further comprising a plurality of pairs of mating alignment elements for automatically lining up the mating pre-molded inserts precisely during the mating of the at least one pair of pre-molded inserts in the molding process, the mating pre-molded inserts fabricated of a nonferrous pre-molded material adapted for withstanding operating temperatures and compression pressure required for a production precision molding process;
- a third step of installing a resilient rubber-like preformed retainer ring around each of the pre-molded inserts by stretching the retainer ring around the perimeter of the pre-molded insert and allowing the retainer ring to snap with a tension fit into the continuous groove encircling the pre-molded insert with a portion of the retainer ring extending outside of the perimeter edge of the pre-molded insert, pre-molded insert being insertable, removable and replaceable, the retainer ring fabricated of a nonferrous rubberlike material adapted for withstanding operating temperatures required for a production precision molding process;
- a fourth step of snapping at least one pair of pre-molded inserts into a mating pair of window openings in the pair of mating carrier plates to secure each pair of mating pre-molded inserts in one mating pair of window openings of the carrier plates, each retainer ring snapping into the recessed groove around the window openings, the retainer ring having a resilience sufficient to allow motion of the insert in an X axis, Y axis and Z axis thereby forming a three-axis floating mold when the mating pre-molded inserts are moved together into a mating position in the molding process, thereby forming a multiple material assembly with mating pairs of three axis replaceable floating molds attached to at pair of removable carrier plates for use in production precision molding;
- a fifth step of installing the multiple material assembly carrier plates in a precision molding device and using them for precision molding;
- thereby performing a multiple material carrier plate assembly molding method using mating pairs of three axis floating replaceable pre-molded inserts attached to window openings in pairs of removable carrier plates, each pre-molded insert having at least one mold cavity.
