ADJUSTABLE JACKET FOR MQLIJ USED IN FOUNDRIES Filed May 9, 1966 5 Sheets-Sheet 5 mvzu'ron j Jose 0h Gardelld I United States Patent 3,402,759 ADJUSTABLE JACKET FOR MOLD USED IN FOUNDRIES Joseph Gardella, 4133 57th St., Woodside, NY. 11377 Filed May 9, 1966, Ser. No. 548,503 10 Claims. (Cl. 164396) This invention relates to mold jackets which are used in place of flasks during the pouring of the molten metal into the mold and more particularly to a sectional four-sided squeeze jacket for sand molds.
Sand molds are usually either straight or tapered, that is, they are made either with vertical sides or with sides converging toward the top of the mold. Slip jackets are opened so as to be readily slipped on or removed from the molds. They are usually made to fit the type of mold, which is'to be held, either straight or tapered; and a straight-type jacket is not suited for use in holding a tapered mold, or vice versa. In some cases, the slip jackets are made in one piece. Other types of slip jackets have their sides welded or bolted together. All of these types of slip jackets are inflexible. They must be made precisely to fit a given size and type of mold. In some cases, slip jackets have been made, however, with their sides hingedly connected together at one corner and held together at another corner by springs and bolts. This construction permits of easily positioning of the jacket on the mold or removing it therefrom, but like the jackets first described is relatively inflexible and costly.
A principal object of the present invention is to provide a slip jacket that will be relatively cheap and that can readily and quickly be put on or taken off of a mold.
Another object of the present invention is to provide a squeeze or slip jacket with sides and ends that automatically adjust themselves to the size of the mating mold.
Still another object of the invention is to provide a squeeze or slip jacket that is readily adjustable for use with molds of different heights.
A further object of the invention is to provide a squeeze jacket that can be readily assembled and easily and conveniently manipulated in use.
Yet another object is to provide a jacket of this type for mold bodies of sand or the like material having a more simple, practical and eflicient type of construction.
For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material part of this disclosure:
FIGURE 1 is a top perspective view of a squeeze jacket for molds embodying the invention.
FIG. 2 is a horizontal sectional view taken on the plane of the line 22 of FIG. 1.
FIG. 3 is a vertical sectional view taken on the plane of the line 33 of FIG. 1.
FIG. 4 is a fragmentary perspective disassembled view of one corner of the jacket.
FIG. 5 is a perspective view showing a number of jackets around molds being transported on belts to receive the molten metal.
FIG. 6 is a top perspective view of a mold jacket embodying a modified form of the invention, and
FIG. 7 is an elevational detail view of a modified form of supporting leg.
Referring now in detail to the various views of the drawings, in FIG. 1 a squeeze jacket embodying one form of the invention is illustrated and designated generally at 10. The jacket 10 is for use with molds having straight sides or sides slightly tapering toward the top,
"ice
as is customary with molds used for metal and especially for steel casting, which molds usually rest on a bottom board or mold table. The jacket is formed of metal and rectangular in configuration and is sectional having an outer structure 12 and an inner structure 14.
The inner structure 14 includes a pair of rectangular side plates 16, 16 a pair of rectangular end plates 18, 18, the plates having smooth inner surfaces and being held together loosely in box-like formation by tongues 20 on the ends of the end plates interlocking with grooves 22 on the adjacent ends of the side plates. Angle metal strips 24 and 26 are welded to the inner surfaces of the side and end plates 16 and 18, respectively, at the tops thereof, the strips being extended over the top edges of the plates and slanted downwardly forming flanges 27 and 29, respectively, the flanges being connected by mitre joints 30.
A wedge member 32 tapering downwardly and outwardly from top to bottom is welded to each side plate 16 and each end plate 18, adjacent each end thereof. A rectangular shaped guide finger 34 is welded at one end to the plates adjacent the wedge member 32. The guide finger 34 is formed with a hole 36 extending therethrough. Inwardly of the finger 34 each, plate 16 and 18 is formed with a vertical slot 38 for receiving a screw 40 supporting a slotted leg 42, whereby the leg is adapted to be adjusted up and down along the slot. An angular metal post 44, L-shaped in cross-section, is slidably mounted at each corner of the inner structure, the post overlapping the joint thereat. One leg 46 of the post is formed with a vertical slot 48 to receive screws 50 for removably and adjustably fastening the post to the adjacent end plate 18.
The inner structure 14 is nested inside the outer surface 16 as shown in FIG. 1. The outer structure 16 includes a pair of side plates 52, 52 and a pair of opposed end plates 54, 54 connected by mitre joints 56 on the side plates. The outer structure is slightly spaced from the inner structure and the plates 52 and 54 are formed with downwardly slanting integral flanges 58 and 60, respectively, which underlap the flanges 24 and 26 of the inner structure 14 as shown in FIGS. 1 and 3.
Wedge members 62 and 64 are Welded to the inner surface of the side plates 52 and end plates 54, respectively, the wedge members tapering downwardly and inwardly in order to coact with the wedge members 32 on the plates 16 and 18, of the inner structure. The side plates 52 and end plates 54 are also formed with vertical slots 66 and 68, respectively, through which extend the guide fingers 34 projecting from the side and end plates 16 and 18 of the inner structure 14 for guiding the horizontal and vertical movements of the inner structure. Pins 70 removably mounted in holes 36 in the protruding ends of the guide fingers 34 prevent detachment of the inner and outer structures from each other. The side and end plates 16 and 18 of the outer plates 52 and 54 are also formed with cutouts 74 and 76, respectively, to reduce the weight of the jacket.
In operation, as soon as the so-called setting of the mold (removal of a snap flask or the like) has been performed, the bottom of the jacket is placed over the top of the mold and then carefully lowered downwardly over the mold. As soon as the legs 42 and corner posts 44 engage the rail or bottom board of the mold, the wedge members 32 and 62 move relatively thereby moving the plate 16 and 18 inwardly whereby the jacket is tightly locked to the mold and no play is possible. The tapering of the wedge members removes all play which may exist.
With the wedge members 62 and 64 of the outer structure bearing against the wedge members 32 upon the side and end plates 16 and 18, respectively, of the inner structure, any tendency of the side and end plates to flex during the pouring of the molten metal into the mold is counteracted and therefore the mold is held in its most favorable condition for the pouring operation. The weight of the outer structure, itself, is sufiicient to force the side and end plates 16 and 18 into relatively tight engagement with the mold by downward movement of the wedge members 62 and 64 into cooperative engagement with the wedge members 32. However, the side and end plates 16 and 18 may be moved manually into rigid engagement with the mold by the operator positively depressing the outer structure into engagement with the inner structure.
The top flanges 27, 29, 58 and 60 protect the movable parts of the jacket from hot molten metal. The feet and corner posts of the inner structure 14 are adjustable up and down to accommodate a flask with a 3", 4" or drag. By lowering the wedge members 32 and 62, the jacket can be used with high copes.
In FIG. 5, a number of squeezes or slip jackets containing molds 80 is shown mounted on boards 82, 82 being transported on belts 84, 84 driven by rollers 86, only one roller being shown.
FIG. 6 illustrated a modified form of supporting leg 42 and slidable and swingable mount therefor. Herein, the plate 16' is shown formed with a vertical slot 88 and a slanting slot 89 at each side thereof, the bottom ends of the slots communicating and intersecting. The rectangular shaped flat leg 42 carries a radial pin which is adapted to slide in either of the slots so that when the mold and jacket are being lifted off the support, a tool may readily enter under the mold and jacket by striking the leg and automatically tilting the leg, such for exam ple, as shown in dash lines in FIG. 6.
FIG. 7, a squeeze or slip jacket 10 embodying a modified form of the invention is shown. The jacket 10" differs from jacket 10 of FIG. 1 in that an upright post 90 is welded to the plates 52" and 54 of the outer structure alongside each slot 66 and 68", respectively, there of, the opposed posts serving as guides for the vertical movement of the fiingers 34" and serving as abutments for the pin 70".
