To all whom it may can Gem:
Be it known that I, HENRY C. ZEN-Km a citizen of the United States, residing in Richmond Hill, county of Queens, State of New York. have invented an Improvement in Metal-lvlolding Apparatus (Case 7 of which the following is a specification.
This invention relates to apparatus for molding metals and more particularly to ap= paratns for casting type lead, such as is used in the printing art, into pigs.
One of the objects of this invention is to provide a simple and practical metal mold ingapparatus by means of which type metal, for example, may be cast into pigs of con venient size and shape,'such for example as may be readily fed to type casting machines, and in which simplicity of construction is combined with facility of operation when in use.
Another object is to provide a practical and effective means for securing the severalparts of the molding apparatus together for receiving the molten metal.
Another objeet'is to provide a metal molding apparatus from which the cast pigs may be readily ejected with a minimum efiort and in which the separation of the several parts of the molding apparatus to permit the ejection of the pigs may be efiected in a simple manner and with a minimum expenditure of manual effort.
Other objects will be in part obvious or in part pointed out hereinafter,
To embody my invention I have provided a central upright standard with mold members hinged thereto with a clamping device for securing the parts together during the opened.
process of molding and means for ejecting the molded pigs of metal when the mold is In. the accompanying drawings in which is shown an embodiment of my invention.'
Figure 1 is a perspective view of the molding apparatus showing the several parts in assembled but open position;
Figure 2 is a perspective view showingthe several parts of the molding apparatus in closed position and looked together in readi ness to receive the molten metal;
Figure 3 is a plan view on an enlarged scale of the clamping device for holding and locking the several parts in closed position; and p Figure 4 isa partial sectional view on the line 14 of Fig. 3,-showing the details of the toggle embodied in the loc-kingdevice ot F1n'. 3; and I Figine -5 is a partial "sectionalview on the line 5 5 of Fig. 1 on enlarged scale vided with two oppositely extending arms 14- and 15, each extending away from the supporting member 10. To the upper end andup'on the opposite side of the support ing member 10 there is secureda bracket 16 similarly positioned and of similar construction as the bracket 13 so as to provide two oppositely extending arms 17 and 18. The arms 14: and 17 form a pair of supports for a mold member 19, at the upper end of which there are suitable outwardly extend ing arms 20 and 21, the outer ends of which are pivotally connected by means of the rod or pin 22 to the outer ends of the supporting arms 14 and 17 respectively A handle preferably formed integral with the arm 20 ot the mold member 19, swings the mold member 19 about its pivotal suspension;
To the outer'e'nds of the other pair of arms 15 and 18 there is suspended another mold member 24 by suitable arms '25 and 26 and by the pin 27, a handle 28 forming an extension of the arm 26 being provided for manually controlling the position of the mold member 24;. The mold members 19 and 24 are of substantially identical construction and are suspended with respect togthe supporting member 10 in substantiallyidentical manner as already set forth; Hence;
only one of the mold members 19 and 24 will be described in greater detail together with its associated operating mechanisms.- A
As may be clearly seen in Figs. 1 and 2, each mold member is preferably provided with two metal-receiving spaces or compartments, whosedimensions and shape are such as it is desiredto give the castpig. Thus the mold member 19 is provided with two metal-receiving spaces 29 and 3Q and the the several views in the mold member 24 is shaped to form two spaces 31 and 32 adapted to give the pigs the desired conformation. The wall, such as the wall 33 in the mold member 19, which separates the two metal-receiving chambers is preferably cored out to provide at the exterior of the mold member a series of open recesses as 34, thus to increase the surface exposed to the atmosphere and therefore to increase the radiation of heat from the mold. Excessive masses of metal which tend to retain heat are thus avoided in the construc tion of the mold-forming parts and a more rapid cooling of the structure is thus attained.
Each face of the supporting member 10 has its surface raised as at 35 in an outline corresponding substantially to the outline of the inner end faces of the wall-forming portions of the mold members 19 and 14. The raised portions 35 of the supporting member 10 may thus be readily machined or finished so that the correspondingly machined or finished edges of the wall-forming portions of the mold members 19 and 24 may snugly contact therewith and form a metal-tight connection therebetween. The supporting member 10 is preferably cored out so that a supply of cooling water may be circulated through its interior, as by means of the pipe connections 36 and 3' which may function as the inlet and outlet respectively.
By reason of the eccentric pivotal suspension of the mold members 19 and 24 to the supporting member 10, as hereinbefore described, each mold member will tend to swing in an outward direction or away from the supporting member 10 and into the position shown in Fig. 1. This action takes place because the axis of suspension of each mold member is positioned exteriorly of the vertical plane passing through the center of gravity of each mold member and exteriorly also of the supporting memberlO. In other words, the pivot point of each mold member is positioned eccentrically with respect to the center of gravity of the corresponding mold member. Each mold member 19 and 24 may he swung inward and into contact with the supporting member 10 by means of the operating handles 23 and 28 respectively, thus to permit the supporting member 10 to function as the closing side for each metal-receiving space or compartment in each of the mold members 19 and 24. In order, however, to hold temporarily each mold member 19 and 24 in the closed position so as to permit of the application of a suitable clamping device for locking the several parts in closed position, I have provided an automatically operating latch adapted. to hold each mold member in closed position. As shown in Fig. 1, there is mounted at preferably the lower part of the end wall of the member 10 a pin 38 which is adapted to be engaged by the hook portion or latch 39 on the inner end of a lever 40 pivotally mounted at the lower exterior portion of each mold member 19 and 24. The lever 40 is preferably secured to one end of ashaft 41 mounted in the bearings 42 integrally formed'in a suitable housing 43, which may be mounted upon the exterior and lower portion of each mold member in any suitable manner.
Each housing 43 is formed into two chambers 44, one for each of the mold-receiving spaces in each mold member. In Fig 5 of the drawings is showna vertical sectional view taken through one of the chambers 44 and it will be noted that to the shaft 41 there is secured an arm 45 adapted to be contacted with by the pin 46 sliding in the end wall 47 of the housing 44 and projecting through the outer wall of the mold member 19. A spring 48 surrounds the pin 46 and is interposed between the wall of the mold member 1.9 and a pin or collar 49 rigidly secured to the pin 46. The spring 48 thus urges the pin 46 outwardly. A second pin or collar 50 mounted at the upper end of the pin 46 and adapted to engage with the inner face of the wall 47 of the housing 44 limits the upper movement of the pin 46 in response to the action of the spring 48 so as to maintain the lower end face of the pin 46 substantially flush with the interior face of the outer wall of the mold member 19.
The spring 48, however, also tends to ro tate the shaft 41 in a counter-clockwise direction, as viewed in Fig. 5, and hence tends to maintain in an upper position the outer end of the lever 40 at which the hook portion or latch 39 is mounted. As each mold member 19 and 24 is swung inward into the closed position, as shown in Fig. 2, the latch 39 on each mold member 19 and 24 will engage with the pin 38 and will be held in engaged position by the action of the spring 43. The mold members 19 and 24 are thus held against the action of gravity in the closed position by their respective latches'39.
In order to lock each mold member against the main supporting member 10 which, as hereinbefore noted, thus forms the closing side of the metal-receiving spaces in the mold member, there is provided a clamping device comprising the yoke member 51 se cured at its central portion to a middle part of the end wall of the supporting member 10 by means of a hinge 52, more clearly shown in Fig. 3 of the drawings. The yoke 51 may thus be swung from the position shown in Fig. 1, in which it is out of engagement with the several mold-forming parts, into the position shown in Fig. 2 in which the twomold members 19 and 24 with their common interposed supporting member 10 are adapted to be engaged by the several devices mounted in the ends of the yoke 51. One end of the yoke 51 is adapted to engage the moldmem ber 24 at .a substantially central point therein by the screw 53 threaded into the boss 54 formed in the one end of the yoke 52and substantially opposite a boss 55 in the opposite end of the yoke 51. 1 The boss 55 is bored out to provide a substantially cylindrical guide for a plunger 56 whichis adapted to be moved toward or. away from the screw 54 in the opposite end of the yoke by means of a'suitable toggle. This toggle (see Figs. 3 and 1) comprises the link 5! in pivotal engagement with the outer end of the plunger 56 and a complementary -toggle-forming member comprising a pair of links 58 pivoted upon the bolt 59 mounted on the boss 60. The link 57 is pivotally connected to the pair of links "58 by'a pin 61 which extends through a yoke 62 whose upper end is bifurcated as at 63 to receive the operating handle 64 pinned theretoby means of the pin 6-5. The operating handleea is suitably pivoted at its one end to the yoke 51 as at 66. The two arms of-the lever'may be given any desired'proportion according to the multiplying effect desired to be attained.
The mold members 19 and 2a having'been placed in the closed position by means of metal. the several parts are clamped'together may their respective operating handles 23 and 28 and having been held in such closed posi-, tion by their respective latches 39, the yoke 51 is thereupon swung into. the position shown in Fig. 2 by means of the operating handle 64. Continued movement of the operating handle 64 causes the operation of the toggle 5758 so to force the plunger 56 inward. Themold members 19 and 24,
in engagement respectively with the plung F er 56 and the screw 53, are securely clamped and'locked against the supporting member 10 and the several parts are in readiness to receive. a charge of molten The degree of tightness with which bereadily adjusted by means of the screw 53. forming one of the contacting parts of the clamping device, and it will be noted that this adjustmentmay readily be made with respect to the toggle-forming links 57 and 58 so that the toggle is straightened out and locked at the desired adjustment.
Upon the cooling and setting of the metal within the several mold receiving spaces,-
the clamping device is unlocked and swung about its hinge 52 and i into the position shown in Fig. 1. Themold members 19 and 24h, howeven'will be. retained in-a closed position by reason of the action, ofthe latches operated bythe operator, causes such a rotation of the shaft 4-1 as will swing the latches 39 away from their respective pins 38 and permit the action of gravity to become eflective to swing the mold members,
into the position shown in Fig. 1. The same movement of the shaft 31 by virtue of the lever 61 is effective also to cause an inward movement of the pin 46, there being one for'each metal-receiving space as hereinbefore described, against the action of the spring 48. The pig cast within each space is thus dislodged from the wallsof the mold members 19 and 24 and is readily discharged therefrom and between the parts now inthe position shown in Fig. 1. It will be understood that the release of the latches St and the ejecting movement of the pins 46 are initiated by the same operation of the lever 67- and, furthermore, that the effort applied to the lever 67 is applied in such in swinging the respective mold members away from the main supporting member to permit the discharge of the cast pigs.
In the embodiment hereinbefore .described, each mold member 19, and 24 has been described as having two metalreceiv-.
direction as to assist the actionof gravity ing spaces, but it will be understood that a greater or smaller number of metal-receiving spaces may be incorporated in each mold member. that irrespective of the number of metalreceiving spaces employed, the upper open ends of the molds are in close proximity to is simple and practical and that a minimum amount of effort need be exerted in the manual operation thereof, thus bringing" Furabout convenience in manipulation. thermore, it will be noted that in this apparatus the several objects of this invention, as well as many advantages, have been attained.
e As many possible embodiments may be madeof this invention and as many changes might be made in the embodiment above set forth, it will be understood that all matter herein set forth is to be interpreted as illustrative and not in alimiting sense.
