    摘要: An investment casting pattern is formed by forming a metallic first core element (50) including at least one recess (34). The first core element (50) is engaged to at least a mating one of an element (60) of a die and a second core element. The recess (34) serves to retain the first core element (50) relative to the mating one. The die is assembled and a sacrificial material is introduced to the die to at least partially embed the first core element. The recess (34) may be pre-formed prior to cutting the first core element (50) from a larger sheet of material.

    摘要: A sublimation pattern casting method capable of achieving the optimum discharge of generated gas, comprising the step of performing a casting while discharging the gas generated by the sublimation of the pattern to the outside of a mold through a discharge passage having a discharge gas suppressing means when a product is cast by filling molten metal into the mold formed by burying a synthetic resin foam body pattern in foundry sand to sublimate the pattern by the molten metal, wherein the permeability of the discharge passage is controlled based on the material and shape of the pattern and the type and temperature of the molten metal.

    摘要: An investment casting pattern is formed by installing a first core (20) to a first element (60) of a molding die (58) to leave a first portion (24) of the first core (20) protruding from the first element (60). After the installing, the first element (60) is assembled with a feed core (70) and a second element (62) of the molding die (58) so that the first portion (24) contacts the feed core (70) and is flexed. A material (92) is molded at least partially over the first core (20) and feed core (70).

    摘要: A fugitive pattern assembly is made by preforming one or more fugitive patterns of an article to be cast, placing the preformed patterns in an injection die, and injecting fluid gating material into the die to form gating connected to the patterns. The fugitive patterns are disposed in end-to-end and/or side-by-side relation and are interconnected by the gating.

    摘要: A casting (60) includes a heat transfer surface (80) having a plurality of cavities (110). The plurality of cavities (110) include a density of at least about 25 cavities per square centimeter to about 1,100 cavities per square centimeter resulting in increased surface area and therefore enhanced heat transfer capability. Also disclosed is a mold (200) for forming a pattern (300) for molding the casting (60). The mold includes a surface defining a portion of a chamber (205) to which are attached a plurality of particles (220) having an average particle size in a range of about 300 microns.

    摘要: The present invention is a dental investment material 50 comprising hemihydrate gypsum and a refractory material as a main component mixed with a calcium carbonate. The invention is also a method for producing a dental investment mold comprising a step for installing, in a frame 2, a wax pattern 3 consisting of a tooth pattern section- 31 having a desired tooth form and a support section 32 which supports the tooth pattern section, a step for casting a dental investment material 50 having a composition described above into the frame while allowing one end of the support section to be intact without embedding but embedding the remainder of the wax pattern 3 in the dental investment material 50 and a step for sintering the dental investment material 50 to evaporate the wax pattern 3 whereby forming a dental investment mold 5 having a cavity 51 which has the desired tooth form.
