Description
Aug. 31, 1943. v v. A. BRENNAN INGOT MOLD Filed Sept. '28, 1942 Patented Aug. 3l, 1943 UNT-TED STATES PATENT orifice INGOT MOLD Vincent A. Brennan, Lynn, Mass.,
Application September 28, 1942, Serial No. 459,984
4 Claims.
This invention relates to certain new and useful improvements in ingot molds.
In the molding of steel ingots and the like, difficulties have heretofore been experienced in producing ingots free from fissures or pipe due to temperature stresses resulting from various rates to cooling throughout the mass of the ingot, especially in those portions which have been exposed to the air during cooling, and it is therefore the object of this invention to provide a mold within which the molten metal will be completely enclosed from the air, and to which pressure can be applied and transmitted to the molten metal Within, thus creating therein compressive stresses to negate temperature stresses due to cooling, and resulting in refining the grain and increasing the strength of the metal cast.
With the above objects in view the invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.
In the accompanying drawing:
Figure 1 isa top plan view of an ingot mold constructed in accordance with the present invention,
Figure 2 is a side elevational view, and
Figure 3 is a vertical longitudinal sectional view taken on line 3 3 of Figure 1.
While the ingot mold may be of any desired cross sectional configuration, such as being polygonally walled, the same is for purposes of illustration, shown as cylindrical and comprises a cylindrical body 5 open at both ends and adapted to be closed by removable closures 6.
The closures are of like construction and each closure E has an intertting connection with the adjacent end of the cylindrical body 5. The closures 6 are 0f disk formation and are of the same diameter as the body 5, each closure carrying an inwardly directed cylindrical block 1 of substantially the same diameter as the internal diameter of the body 5 for intimate contact with the inner face of the cylindrical body as illustrated.
The formation of the cylindrical body l produces a surrounding annular shoulder 8 that faces the adjacent end of the cylindrical body 5 and said shoulder has rising therefrom an annular rib 9 for reception in an annular groove IU formed in the end of the cylindrical body 5.
To provide a perfect seal for the removable closures B in their nterfitting connection with the ends of the cylindrical body 5, gaskets Il, preferably formed of hard rubber, are seated on lil the shoulder portions 8 at the inner and outer sides of the rib 9 and in the bottom of the annular groove IU. The provision of the hard rubber gaskets Il permits the filling of the cylindrical body 5 with molten metal to full capacity before pressure is applied to the end closures 6, and when such pressures are applied the gaskets are compressed which permits the shoulder portions 8 to move closer to the adjacent end of the cylindrical body and the rib 9 to move deeper into the groove ID, such movements of the end closures 5 resulting in excessively heavy pressures being applied to the molten metal and to a degree to cause temperature stresses in the metal to be negated.
From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
I claim:
1. In an ingot mold, a mold body, a removable closure for each end thereof, each closure having a block projection entering the mold body with the outer edge thereof in intimate contact with the inner face of the mold body, the end closures overlying the ends of the mold body outwardly of the block projections and a tongue and groove connection between the overlying portions of the end closures and the ends of the body portion.
2. In an ingot mold, a mold body, a removable closure for each end thereof, each closure having a block projection entering the mold body with the outer edge thereof in intimate contact with the inner face of the mold body, the end closures overlying the ends of the mold body outwardly of the block projections and a tongue and groove connection between the overlying portions of the end closures and the ends of the body portion, including a tongue projecting from the overlying portions of the end closures midway the side edges thereof and a groove in the end portions of the mold body.
3. In an ingot mold, a, mold body, a removable closure for each end thereof, each closure having a block projection entering the mold body with the outer edge thereof in intimate contact with the inner face of the mold body, the end closures overlying the ends of the mold body outwardly of the block projections and a tongue and groove connection between the overlying portions of the end closures and the ends of the body portion, a hard rubber packing interposed between the overlying portions of the end closures and the ends of the mold body and a hard rubber packing in the bottom of the groove for contact by said tongue; whereby the end closures are rendered operative in producing increased pressure on molten metal in the mold for the elimination of temperature stresses during cooling of the ingot.
4. In an ingot mold, a mold body, a removable closure for each end thereof, each closure having a block projection entering the mold body with the outer edge thereof in intimate contact with the inner face of the mold body, the end closures overlying the ends of the mold body outwardly of the block projections, a tongue and groove connection between the overlying portions of the end closures and the ends of the body portion, including a tongue projecting from the overlying portions of the end closures midway the side edges thereof and a groove in the end portion of the mold body, a hard rubber packing interposed between the overlying portions of the end closures and the ends of the mold body and a hard rubber packing in the bottom of the groove for Contact by said tongue; Whereby the end closures are rendered operative in producing increased pressure on molten metal in the mold for the elimination of temperature stresses during cooling of the ingot.
