CASTING IRON IN PERMANENT IRON HOLDS.
Application filed larch 1B, 1922. Serial No. 544,114.
To all whom it may concern:
Be it known that I, Dr; Founs'r W. puts, a citizen of the United States, residng at 2932 \Vest Grand Boulevard, Detroit,
6 in the'county of Wayne and State of Michi gan, have invented certain new and useful Improvements in the Casting of Iron in Permanent Iron Molds, of which the fol w lowing is a specification.
iron in permanent iron molds, and relates specifica ly to the provision of a sand core in conjunction with the sprue and gate.
Figure I shows in elevation the face of a mold with the core in position. Figure II shows a sectional lan view of the two halves of the mold w ien'closed and ready for pouring. Figure III shows in plan view the mold.
In Fig-I, A is the sprue, B is the gate, C is the core, D is the annular clearance between the core C and the mold, E is the matrix, F is the core for the matrix E where the casting requires such a core, G is the core print supporting the core F.
The space D around the dry sand core C is arranged excentrically with relation to (I so that the iron entering at A, flowing through the restricted passage B is distributed around the core C so as to give a substantially uniform flow into the niatrix E, around the core F. That is to say the metal flows into the matrix on the si jacent to the gate B and also through a 3 diminishing annulus around the core G into the matrix E.
Fig. II shows a section through the mold on the planes X-Y and \\'Z..
The advantage of this arrangement is 40 that not only are any impurities in the iron held back by the restriction B, but what is much more important is that the iron as it enters first strikes the sand core B, which being porous, provides a vent for any ases occluded in the iron, the gases escaping through H.
By this arrangement the castings are much more uniform than castings obtaine when the iron enters throu h a sprue placed in'the normal location as s own on the dotted lines to the left of Fig. I, marked A.
InmoldsinwhichaeoreFisnotre- CAN- i My invention relates to the casting of de ad:
quired, the dry sand core C is used nevertheless, as its function is independent of the core F. The thin annular rim east in the annular space D is easily broken off and the fractured surface is easily m What I claim is:
1. In combination with til-permanent iron mold for the die-casting of iron of a substantially vertical. sprue and a substantially horizontal gate of restricted area both lo-- cated within the mold, a sul'ismntially vertical dry sand coreaguinst which the molten iron is delivered laterally, a descending passage for the iron from thegate past the core into the matrixof the mold.
2. In combinat ion with a permanent metal mold for the dierasting of iron a substantially vertical spruc having a substantially horizontal gate oi restricted area both located within the mold, a dry sand core interposed between the gate and the matrix 0 the mold, located above the matrix and arranger] so that the molten metal is delivered laterally againsbthe surface of the core before entering the matrix of the mold, whereby the core can act as a vent to the molten metal as it issues from the gate.
In combination with a permanent metal mold for the die-casting of iron a substantially vertical sprue leading to a sulistantially horizontal gate of restricted area both located within the mold, a dry sand core interposed between the gate and the matrix of the mold. located above the matrix and arranged so that the iron is de livered laterally againstsaid. core an a vent fonthe said core, a passage arranged on one side of said core leading to the matrix of said mold.
4. In combination with a permanent metal mold for die-casting iron, a substantially vertical. sprue having a substantially horizontal gate of restricted area both located within the mold, a cylindrical dry' sand core interposed between the gate and the matrix of the mold, located above the matrix and arranged vertically and e xoentrically within the matrix so as to give a substantially vertical passage on the s de -of the core adjacent to the gate leading downwardly to the matrix.
5. In combination with a permanent iron mold for the die-casting of iron, :1 sprue with an entrance having a substantially vertical aXis, said sprueleadingto 6 a restricted gate, said gate being located laterally with I'BfBJBHCB to said axis, a. dry sand core located between the restricted gate 510mg the cdre leading to the matrix of the and the matrix of the mold, a pessage In testimony whereof I aflix my signature.
