Abstract
Abstract A rapid release mold for use in the compaction of metal powders into consolidated ingots which includes a pair of side walls connected together by means of a relatively rigid bottom buckle plate. The mold includes means associated with the upper portions of the side walls which are operative to slightly increase the separation of the side walls through slight flexure of the buckle plate to permit the unimpeded removal of a compacted ingot from the mold.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
A rapid release mold for use in the compaction of metal powders into consolidated ingots comprising: a pair of parallel side bars laterally spaced from each other a distance equivalent to the width of the ingot to be compacted and defining side walls for the mold cavity; a relatively rigid buckle plate; means securing the buckle plate to the underside of each of said side bars, said buckle plate spaning the space between said side bars at the bottom thereof; an ingot supPort bar lying on said buckle plate between said side bars and defining the bottom of said mold cavity; and means associated with one of said side bars and adapted to be projected into said cavity above a compacted ingot lying therein and coact with the other of said side walls to cause said buckle plate to flex slightly about its center and move said side walls slightly away from each other to permit the unhindered removal of said ingot support bar and said ingot from said cavity.
Claim 2
Dependent Claim
170 words
A rapid release mold for use in the compaction of metal powders into consolidated ingots comprising: a pair of parallel side bars laterally spaced from each other a distance equivalent to the width of the ingot to be compacted and defining side walls for the mold cavity; a relatively rigid buckle plate; means securing the buckle plate to the underside of each of said side bars, said buckle plate spaning the space between said side bars at the bottom thereof; an ingot supPort bar lying on said buckle plate between said side bars and defining the bottom of said mold cavity; and means associated with one of said side bars and adapted to be projected into said cavity above a compacted ingot lying therein and coact with the other of said side walls to cause said buckle plate to flex slightly about its center and move said side walls slightly away from each other to permit the unhindered removal of said ingot support bar and said ingot from said cavity.
Claim 3
Dependent Claim
47 words
A rapid release mold according to claim 1 wherein said means associated with one of said side bars includes a plurality of jack screws mounted in apertures in said one side wall adapted to be threadably advanced into said cavity above said ingot toward said other sidewall.
Claim 4
Dependent Claim
48 words
A rapid release mold according to claim 2 wherein a spacer bar is situated between said side bars above said ingot to coact with said jack screws as the latter are advanced toward said other side wall to thereby move said side walls slightly away from each other.
Claim 5
Dependent Claim
46 words
A rapid release mold according to claim 1 wherein said buckle plate includes a pair of parallel raised portions fitted into complementary slots in the bottom of said side bars and said means securing said buckle plate to said side bars is a plurality of screws.
Claim 6
Dependent Claim
44 words
A rapid release mold according to claim 4 wherein the portion of the bottom of said side bars nearest said cavity is spaced from said buckle plate and sealing means are located within those spaces in the portion thereof most remote from said cavity.
Claim 7
Dependent Claim
76 words
A rapid release mold for use in the compaction of metal powders into consolidated ingots, said rapid release mold comprising: a pair of side walls, a relatively rigid bottom buckle plate secured to the underside of each of said side walls; and means associated with the upper portions of the side walls which is operative to slightly increase the separation of said side walls to permit the unimpeded removal of a compacted ingot from said mold.
Claim 8
Dependent Claim
76 words
A rapid release mold for use in the compaction of metal powders into consolidated ingots, said rapid release mold comprising: a pair of side walls, a relatively rigid bottom buckle plate secured to the underside of each of said side walls; and means associated with the upper portions of the side walls which is operative to slightly increase the separation of said side walls to permit the unimpeded removal of a compacted ingot from said mold.
Claim 9
Dependent Claim
46 words
A rapid release mold according to claim 6 wherein said means associated with said side bars include a plurality of jack screws mounted in apertures in one side wall adapted to be threadably advanced into said cavity above said ingot toward the other of said sidewalls.
Claim 10
Dependent Claim
47 words
A rapid release mold according to claim 7 wherein a spacer bar is situated between said sidewalls above said ingot to coact with said jack screws as the latter are advanced toward the other side wall to thereby move said side walls slightly away from each other.
Claim 11
Dependent Claim
44 words
A rapid release mold according to claim 6 wherein said buckle plate includes a pair of parallel raised portions fitted into complementary slots in the bottom of said sidewalls and said means securing said buckle plate to said sidewalls is a plurality of screws.
Claim 12
Dependent Claim
43 words
A rapid release mold according to claim 9 wherein the portion of the bottom of said sidewalls nearest said cavity is spaced from said buckle plate and sealing means are located within those spaces in the portion thereof most remote from said cavity.
