Definitions

the disclosure of this invention relates to a device for removing a cast article from a bottom pressure-casting machine. It includes a carriage for supporting the bottom mold of the US. machine and hence the cast article
a tractor type power [51] Int. Cl. ..B22d 29/00, 822d 45/00 device is provided at one ide of the casting machine which [58] Field of Search ..164/269, 335, 337, 270, 412; moves the carriage away from the upper mold elements of the 2 machine so that the cast article can be removed from the bottom mold at a location remote from the upper mold elements.
the present invention relates to an article-casting machine in which, while it may be employed in a number of different types of casting machine, for the purpose of illustration only, it is being described with reference to a bottom pressure-pouring casting machine, such as of the type illustrated in US. Pat. No. 3,015,863 issued in the name ofC. F. Strom et al. on Jan. 9, I962.
the gate be allowed to move from an operative position to an inoperative position and vice versa so that after casting, the portion of the metal that solidifies in the mold assembly may be severed from the solidified portion outside the mold assembly so that the cast article can be removed from the mold.
the article was removed from the mold assembly by an overhead crane. This, of course, is quite cumbersome and time consuming, in addition to requiring the services of several workmen.
the present invention provides a very simple yet highly expeditious apparatus for removing the cast article from the mold.
the cast-articleremoving device can be engageable and disengageable from the gate assembly whereby the inner portion of the gate assembly may be removable with the casting leaving the remaining portion of the gate assembly in its operative position and wherein the bottom of the mold itself is adapted to be moved with the cast article.
FIG. 1 is a plan view of a pressure casting arrangement illustrating the portion thereof which involves the present invention
FIG. 2 is an elevational view of the apparatus shown in FIG.
FIG. 3 is a sectional view taken on lines IIIIII of FIG. 1, and
FIG. 4 is a sectional view taken on lines IV--IV of FIG. 1.
FIGS. I and 2 there is illustrated the novel gate assembly and the novel carriage for removing the cast articles.
a pressure vessel which delivers molten metal to the gate assembly, in which the gate assembly directs the molten metal to a mold cavity having a configuration conforming to the contour of the article to be cast.
the cast article for the purpose of illustration, is shown to be a slab which is formed by a cavity defined by side, end, top and bottom graphite mold blocks.
FIGS. 1 and 2 illustrate the slab whereas FIG. 3 illustrates the two end blocks and the cavity defining the thickness of the slab.
the gate is comprised essentially of an outer housing or casing 10 that receives in an opening 11 two refractory liners.
the first liner 12 is arranged in the lower portion of the casing, whereas the second liner 13. being conical in shape, is located in the upper portion of the casing. Both liners are held by a cylindrical retainer 14 which is secured to the casing.
the casing is adapted to move vertically in a U-shaped frame so as to bring the entire gate assembly to a position in forcible contact with the bottom of the mold from a position remote therefrom.
the gate assembly be forcibly maintained against the bottom of the mold during the pouring procedure and that this means be not subject to inadvertent failure of the source of power. Consequently, there is provided, as shown in FIG. 3, a pair of arms 18 which engages the casing 10 at two opposed points, the arms 18 being received in shafts 22, the shafts being rotated by second arms 23, the second arms being connected to spring assemblies 24.
the spring assemblies are designed to provide a positive force sufficient to urge the casing upward and establish the proper sealing condition with the mold assembly.
the cast article removing device may be incorporated so as to remove the gate assembly with the cast article when the cast article is removed from the mold assembly.
the cast article removing device may be incorporated so as to remove the gate assembly with the cast article when the cast article is removed from the mold assembly.
Such an apparatus is shown in the drawings, although it will be appreciated that in the given construction, the gate assembly need not be removable with the cast article.
the lower mold M is mounted on a first carriage 31 having a plurality of wheels 32 which engage with rails 33 so that the bottom mold assembly may be moved longitudinally relative to the side and end mold blocks.
the gate assembly 9 is received in the U-shaped frame 17 which is a part of the bottom mold assembly, whereby the bottom mold assembly and gate may be moved into and out of the mold assembly as a unit.
FIGS. 1 and 2 show, to the side of the mold assembly where the gate 10 is located, there is provided a cast article receiving and supporting device which consists of a second carriage 35 adapted to move transversely of the longitudinal axis of the cast article being mounted on a pair of wheels 36, one being shown in FIG. 2, the wheels being driven by a motor 37 and engage rails 38.
This carriage is adapted to also receive a third carriage 41 which moves normal to the direction of travel of the carriage 35.
the third carriage 41 is received in guide ways 42 and is driven by providing a gear drive that serves as a tractor.
the drive includes two pinions 43 and 44 driven by a motor 45 and, as FIG. 4 shows, the pinions mesh with each other and with parallel racks 46 and 47 and motivate the carriage 41 towards and away from the casting machine.
FIGS. 1 and 2 show, at the one end of the carriage 41 adjacent to the gate 9 there are provided books 48 which engage similar hooks 49 formed on the bottom mold M.
the wheels 32 on the carriage 31 that carry the bottom mold M engage rails 33 in which regard it will be noted that complementary rails 51 are formed on the carriage 35 which are continuations of the rails 33.
the bottom mold M can be moved from its operative position to a position on the carriage 35 on the movement of the carriage 41.
the carriage 41 is provided with inverted L-shaped arms 52 which are adjustable to take into account the varying width of the slab being produced.
the carriage 35 is also provided with upright members 53 which engage the opposite sides of the slab as it is delivered onto the carriage 35.
said power means includes a member which engages the cast article to hold the article in substantially the same position it assumed during casting during its movement away from the upper mold elements.
said power means comprises a tractor mounted on said second set of rails
said gate assembl includes means for movin said gate assembly towards an away from said bottom mo d element.
