Abstract
Embodiments of the invention relate to injection mold components, assemblies, and molding system that include superhard materials. Such injection mold components, assemblies, and systems may decrease wear of certain injection mold components, which may result in improved productivity of the injection mold and molding systems that utilize such components.
Claims20
An injection mold component for use in an injection mold assembly, the injection molding component comprising:
- an injection molding element including a superhard material defining a wear-resistant surface, the superhard material including sintered polycrystalline diamond having a plurality of bonded diamond grains defining a plurality of interstitial regions, at least a portion of the plurality of interstitial regions including a catalyst therein.
An injection mold assembly, comprising:
- a first mold plate;
- a second mold plate;
- one or more molding elements located on one or more of the first or second mold plates;
- and
- an injection mold component at least partially located on or in at least one of the first mold plate, the second mold plate, or the one or more molding elements, the injection mold component including:
- a superhard material defining a wear-resistant surface, the superhard material including sintered polycrystalline diamond having a plurality of bonded diamond grains defining a plurality of interstitial regions, at least a portion of the plurality of interstitial regions including a catalyst therein.

An injection mold press, comprising:
- an injection mold assembly including:
- a first mold plate;
- a second mold plate;
- one or more molding elements located on one or more of the first or second mold plates;
- and
- an injection mold component at least partially located on or in at least one of the first mold plate, the second mold plate, or the molding element, the injection mold component including:
- a superhard material defining a wear-resistant surface, the superhard material including sintered polycrystalline diamond having a plurality of bonded diamond grains defining a plurality of interstitial regions, at least a portion of the plurality of interstitial regions includes a catalyst therein;
- and
- an injection system operably coupled to the injection mold assembly, the injection system configured to convey the material into the mold cavity of the injection mold assembly.
