Definitions
- one object of the present invention to provide a machine for casting of metal work pieces in permanent molds, which causes the filling of the mold in a mechanical operation under the pressure of the content of the melting vessel and, whereby, the mold is filled along the shortest possible way with the result of obtaining the smallest cones.
- the sleeve comprises a hollow stopper freely extending into the melting vessel and having a tapered-down inner cross-section, the bore of the stopper being widened toward the mold.
- the provided effect of the narrow sleeve which extends during each casting operation through the level of the molten metal material, is disturbed due to the very easily oxide skin forming on the melt, particularly if the sleeve extends into the melting vessel for the purpose of an extended heating and an easier tearing-oil of the lug cone.
- the latter is equipped at its lower end, which projects into the molten metal material, with an angularly bent portion extending away from the pouring opening.
- FIGURE 1 is a side elevation of the machine designed in accordance with the present invention.
- FIG. 2 is a front elevation of the machine partly in section along the lines 22 of FIG. 1;
- FIG. 3 is a front elevation of a longitudinal shield for a door iron work cast by means of the machine designed in accordance with the present invention
- FIG. 4 is an end view of the longitudinal shield shown in FIG. 3 partly in section;
- 1G. 5 is a longitudinal section of the machine along the line S-5 of FIG. 2;
- FIG. 6 is a longitudinal section of the machine designed in accordance with the present invention, similar to that of FIG-5, yet in the tilted position of the melting con tainer for, casting; a
- FIG. 7 is a longitudinal section, similar to that of FIG. 5, of another embodiment of the machine.
- FIG. 8 is a section through the melting container. along mg vessel 22 which is disposed in the frame 20 and pivotable about the pins 21 of the latter.
- FIGS. 3 and4 of the drawings a
- longitudinal shield' 1' is shown-forv a door iron work, a which is manufactured by the machine designed in ac-.
- cordance with the present invention and which has alug cone 6 of a small'volume.
- the melting vessel 22 is surrounded by a cover 23 and is closed up at its filling opening by means of a heating cap24.
- the filling ofthe molten metal material takes place in this case along the shortest way through the bottom wall of one mold part 27.
- a lug cone is formed in the sleeve which iswidened. conically towards the mold, which lug cone remains dough-soft. upto liquid, due to the heat fed If the melting vessel 22 is the hollowpart of the sleeve and a lug cone 6 remains,
- FIGS. 7 and 8 another embodiment of the machine designated in accordance with the present invention is disclosed, in which the melting vessel 22, tiltingly mounted in the frame 20 on pivot pins 21, is equipped at its front wall with a pouring'opening, which is formed as a mouth-piece 25- and is disposed at about the level of the, pivoting pins 21.
- the half-part 27 of the mold is rigidly secured to'the melting vessel 22, by means of a cap-like intermediate member 32-
- the other half-part 28 of the mold is hingedly secured to a swinging arm 29.
- the pouring sleeve33 forms, a communication connection of the melting vessel 22.
- a cap 32 is equipped 1 with a pouring sleeve 33 which extends into the mold part 27 and serves as a pouring opening.
- the pouring sleeve 33 consists of a melt resistance and V 7 A preferably adjust-able apron 34 is provided in front of the pouring opening of the melting vessel 22, which apron 34 provides a flow slot below the level x of the molten material (FIG. 5).
- v A piston rod 35 or a power cylinder 36 is secured at its free end to the tiltably mounted melting vessel 22,
- a second piston rod 39 of a second power cylinder 40 is secured at its free end to the swinging arm 29 by means of the arms 37 'and 38. of a bell-crank lever.
- the power cylinder 40 is supported on the pivot bolt 30 of the arm 31, while one arm 38 of the bell-crank lever is pivotally secured to a strut 41 and the other arm 37 is secured to the swinging arm 29.
- the'melting vessel 22 can be moved into its tilted position (FIG. 6) and again returned to its original position (FIG. 5).
- a V In the pouring position (FIG. 6) the melting vessel 22 is tilted, so that the level 'xof the molten metal material assumes a different position.
- the pouring sleeve 33 assumes a position below thelevel of the molten metal material and the latter flows into the par-ts 27 and 28 of the'mold under the pressure of the liquid
- a separating wallSti whichextends below the level x of the molten metal material, is disposed in front of the tapered-down end and the mouth-piece 25 of the melting vessel 22, preferably ,at a predetermined distance from the front wall of the latter for the purpose of separation of a chamber Z defined between the separating wall 50 and the wall of the melting vessel 22 and for feeding a protecting gas into the chamber Z.
- the latter extends also beyond the chamber surrounding the pouring sleeve 33 0f the melting vessel 22 and of its mouth-piece 25.
- this angularly bent portion 56 dips in each tilted position sufficiently deep into the melt, and also for instance, if the level x of the molten material assumes'the position x1.
- the remaining flow slot can be designed of sufiicient width and due to the angularly bent portion 56 afunnel-like filling means can be formed.
- the protection gas which is chosen in accordance with the melting alloy to be worked, is-fed to the chamber Z underv pressure, slightly higherthan atmospheric pressure, through the conduit 55, so that the chamber Z is always filled with the protecting gas.
- the pouring sleeve 33 in case a long shield cast is to be made, in such manner that a forming core 43 (FIG. 5) is disposed opposite thereof, which forming core 43 projects into the pouring sleeve 33 with a projection and which hollows the lug cone 6, whereby the latter can be cut oil more easily.
- a forming core 43 FIG. 5
- the mold may be also divided into a plurality of separate chambers.
- a machine for easing of metal working pieces in a permanent mold comprising at least two parts, said machine comprising a tiltable melting vessel having a plurality of walls,
- said mold having filling means
- said melting vessel having a mouth-piece defining a chamber Widening into said melting Vessel
- said pouring sleeve having a bore conically widening and extending into said mold, as well as tapered down and projecting into said chamber.
- said separating wall forming in its upper portion an angle intermediate its ends
- connection branch secured to asid upper portion of said separating wall
- connection branch a conduit leading to said connection branch and adapted to feed a protecting gas into said chamber.
- said melting vessel is pivotally mounted on bearing pins and the free end of said piston rod is secured to said melting vessel at a point spaced apart from the pivot axis, so that the movement of said piston rod brings about a tilting movement of said melting vessel,
- bearing pins being disposed in a plane extending through said mouth-piece
- said mold consists of at least two mold parts
- one of said mold parts is carried at the free end of said swinging arm.
