摘要： An example mold assembly system includes a mold assembly including a mold forming a bottom of the mold assembly, a funnel operatively coupled to the mold, and an infiltration chamber defined at least partially by the mold and the funnel, the infiltration chamber being used for forming an infiltrated downhole tool. A mold assembly cap is positionable on the mold assembly and including a sidewall extendable about an outer periphery of the mold assembly at least partially along a height of the mold assembly. The sidewall exhibits a horizontal cross-sectional shape that accommodates a shape of the mold assembly and the sidewall is made of a thermal material that promotes directional solidification of the infiltrated downhole tool during fabrication.

摘要： An example mold assembly for fabricating an infiltrated downhole tool includes a mold defining a bottom of the mold assembly and a funnel operatively coupled to the mold. An infiltration chamber is defined at least partially by the mold and the funnel to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated downhole tool. A thermal mass is positioned within the infiltration chamber above the infiltrated downhole tool for imparting heat to the infiltrated downhole tool following an infiltration process.

摘要： An example insulation enclosure includes a support structure having a top end, a top wall provided at the top end, a bottom end, and an opening defined at the bottom end for receiving a mold within an interior of the support structure. Rigid insulation material may be supported by the support structure and extending between the top and bottom ends and across the top end. The rigid insulation material may extend between the top and bottom ends and consist of one or more sidewall insulation loops that extend along a circumference of the insulation enclosure.

摘要： An example insulation enclosure includes an outer shell having an open end and a top end, and an inner shell arranged within the outer shell and including a plurality of sidewall members and a top member. Each sidewall member is independently moveable relative to one another and to the top member, and the plurality of sidewall members and the top member each include a support member and insulation material positioned on the support member. One or more compliant devices arranged between the outer shell and at least one of the plurality of sidewall members and the top member, the one or more compliant devices biasing the at least one of the plurality of sidewall members and the top member against adjacent outer surfaces of a mold disposable within the inner shell.

摘要： A mold assembly and method for fabricating an infiltrated drill bit may comprise a mold forming a bottom of the mold assembly, a funnel operatively coupled to the mold, an infiltration chamber defined at least partially by the mold and the funnel to receive and contain matrix reinforcement materials and a binder material used to form the infiltrated drill bit, a displacement core arranged within the infiltration chamber and having one or more legs that extend therefrom, a metal blank arranged about the displacement core within the infiltration chamber, and one or more thermal elements. A method may comprise providing a mold assembly having component parts that include a mold that forms a bottom of the mold assembly and a funnel operatively coupled to the mold, imparting thermal energy to the infiltration chamber with one or more thermal element, and heating contents contained within the infiltration chamber.

摘要： An example cooling system for a mold assembly includes a quench plate that defines one or more discharge ports and one or more recuperation ports. A fluid is circulated from the one or more discharge ports to the one or more recuperation ports to cool the mold assembly. A blocking ring is positioned on the quench plate and defines a central aperture for receiving a bottom of the mold assembly. An insulation enclosure having an interior for receiving the mold assembly is positioned on the blocking ring. The blocking ring prevents vapor generated by the fluid contacting the bottom of the mold assembly from migrating into the interior of the insulation enclosure.
