CASTING MACHI NEFOR THE CASTING OF PLANE STEREOTYPE PLATES Filed Feb. 27, 1935 2 Sheet's-Sheet 2 Patented Mar. 16, 1837 PATENT OFFICE CASTING MACHINE FOR THE CASTING OF PLANE .STEREOTY PE PLATES Ernst Brockel, Augsburg, Germany, assignor to Maschinenfabrik Augsburg-Niirnberg A. G., Augsburg, Germany, a corporation of Germany Application February 27, 1935, Serial No. 8,427 In Germany March 3, 1934 3 Claims.
My invention refers to a casting machine for the casting of stereotype plates wherein the melting. pot and the casting mold which are connected with each other by a conduit, are swung together into the casting position so that the casting mold is subjected during the solidification of the plate to the pressure of the contents of the melting pot, and the connecting conduit between the melting pot and the casting mold is heated so that the still liquid metal contained in it can flow back into the melting pot when the latter is swung back into the position of rest.
The present machines of this kind are con-.
structed for casting semi-cylindrical plates. It is the object of this invention to adapt such casting machines also for casting plane plates. According to the present invention, the upper and lower parts of the casting mold and the melting pot are moved away from each other in an approximately horizontal direction; the upper and lower parts of the mold are separated from each other only in this end position so that the plate lies quite open before the operator.
In the accompanying drawings showing a con- 5 structional example of the invention,
Fig. 1 is an elevation and Fig. 2 a front view of the machine, while, Fig. 3 being a similar view as Fig. 1 shows a modification.
The melting pot I is secured to panels 2 and 3 which are rotatably mounted upon a shaft 4. The casting mold which consists of a lower part 5 and an upper part 6, is secured to two supports I and 8 which are rotatably mounted upon a shaft 9 which is mounted with its. ends in the panels 2 and 3. The shaft 3 is mounted with its ends in fixed frame sides ID and H. When the casting mold has been pressed firmly against the melting pot l, as shown in full lines in Fig. 1, it can be swung together with the melting pot I about shaft 4. On a lever l2 being turned about a pivot l3mounted in the frame side H, a roller l4 fixed to the lever l3 slides in a slot l5 of the panel 3, up and down. By this means, the panel 3 and consequently also the melting pot I as well as the casting mold 5, 6 which is pressed firmly against the melting pot, are swung to such an extent about the shaft 4' that the melting pot is above the casting mold and metal p contained in the melting pot flows intothe casting mold through the connecting conduit it, which latter is heated by heating devices l'l.
Before the casting operation, the casting inold 5, 6 was pressed firmly against the casting mouth of the melting pot l by the turning of the lever Ill. The upper part 6 of the casting mold is then locked with regard to the lower part 5 of the casting mold by means of a hook l9 which is secured to the lever l8 and engages a pin 29 provided upon the upper part 6 of the mold.
After the solidification of the plate, the melting pot and the casting mold are moved back into the position shown in full lines in Fig. 1 by a downward swing of the lever l2. The metal contained in the connecting conduit it between the melting pot and the casting mold, remains, due to the heating by the heating devices l'l, liquid at the end adjacent to the melting pot, and consequently fiows back into the melting pot as the latter is swung back to its initial position. In order to remove the small head which remains upon the cast plate from the connecting conduit Iii, and in order to readily open the casting mold, the latter is first moved away in a downward direction from the melting pot by a corresponding turn of the lever 18, and is brought into the position shown by the broken lines in Fig. 1. The supports l and 8 which are, as pres viously mentioned, secured to the lower part 5 of the casting mold, turn during this movement about shaft 9. On the downward movement of the lever 18 which swings about a pivot 2i fixed to the supports! and 8, the hook I9 secured to lever I8, is released from the pin 2i],v on the upper part 6 of the mold which thereby becomes unlocked. The hook I9 is pivotally connectedby a pin 22 with a lever 23 forming therewith a toggle joint. The lower end of lever 23 is mounted by means of pivots 24 in the supports 1 and 8. Therefore, as the lever I8 is moved downwards and the hook l9 and consequently the pivot 22 fixed thereto are turned, the lever 23 turns about its pivot 24, and the panels 2, 3 together with the casting mold 5, 6 are drawn away from the melting pot. To enable the casting mold to be opened and the cast plate to be removed, the upper part B of the casting mold is adapted to be swung sideways about a stud 25 mounted in the lower part 5 of the casting mold, so that the cast plate will be fully exposed to the operator and can be readily removed. 7
Fig. 3 shows a modification in which the closed casting mold consisting of the lower part 5 and the upper part 6, remains undisturbed after the swinging back of the melting pot and the casting mold, into their initial position, and the melting pot l is displaced approximately horizontally from the position shown in full lines to the position I shown in broken lines. The casting mold 5, 6 assumes a somewhat inclined position so that the metal which has not yet solidified cannot flow out of the mold, on the melting pot being moved away from the mold. For moving the melting pot away from the casting mold, the shaft 26 which is mounted in the panels 2 and 3 loosely mounted at both sides of the melting pot l upon the shaft 4, and which shaft extends under the melting pot I, is turned by the lever 38 being moved from the position shown in full lines to the position 38' shown in broken lines. The shaft 4 is mounted with its ends in the fixed side frames l0 and II. The panels 2 and 3, after the swinging back of the melting pot and the casting mold into the position of rest, are held by a. weight 2'! in the latter position. Upon the shaft 26 are fixed at both sides of the melting pot, levers 28, which by the swinging of the lever 38 are moved into the position 28'. These levers 28 as they are rocked move links 29 with which they are pivotally connected, said links engaging with their free ends two rollers 30 fixed to the two sides of the melting pot I. These rollers slide during the movement of the links 29, in slots 3| of the panels 2 and 3; by this means the melting pot l is moved away from the casting mold 5, 6 to the position shown in broken lines. The melting pot rests during this movement upon two further rollers 32 fixed to its sides, said rollers sliding during the lateral movement of the melting pot in slots 33 of the panels 2, 3. The rollers 32 are connected with a two-arm lever 34, S5 turning about shaft 36. During the displacement of the roller 32, the lever 34, 35 moves into the position 34, 35 shown in broken lines; in this position the arm 35 acts as a lock relative to a locking member 3'! fixed upon shaft 4; it is then impossible to turn the lever l8 which is used for simultaneously swinging the melting pot and casting mold, after the melting pot I has.
been moved away from the casting mold 5, 6.
I claim:
1. In a device for casting plane stereotype plates, in combination a melting pot, a mold adapted to receive the molten metal from said melting pot and comprising two superposed parts hinged together permitting the top part to be tilted sideways relative to the bottom part, cooperating members for locking said parts together, means for moving said melting pot and said mold together about a common axis from inoperative to casting position, and vice versa, a
connecting duct intermediate said melting pot and said mold, heating means for said duct, and means independent of said first means for moving said mold away from said melting pot to a substantially horizontal position upon the return of said melting pot and said mold to their inoperative position.
