Definitions

  • the invention relates to an improved process for the production of completely cast type-line bodies for matrix-composing and type-line casting machines and the arrangements for Carrying out this process.
  • Thetype-lines produced by the so-called complete casting process that is to say, the finished casting process, are distinguished by the fact that they leave the casting -mould as completely finished bodies, and after the casting no further mechanical treatment'of the surfaces thereof is required with the exception of a small trimming at the edges of the faces, which does not affect-the bottom and side The base of the surfaces of thetype-line bodies.
  • type-line bodies is formed by a ledge extending along the side surface and two transverse feet situated at the ends of the lines, while the runher, that is to say, the breakingpoint remaining 'after the removal ofthe casting head or the waste in the type-line body, is sunk with respect to the base of the type-line and therefore does not detrimentally affect the stability of the type- ".line-body.
  • This form of type-line base is obtained by means of a casting slot, shortened at :its ends by an amount equal to the length of the transverse feet withrespect to the length of the type-line, within the so-called intermediate plate ,provided in known manner between the mould and the casting mouth of the casting pot. This known successful complete'casting process has,
  • each casting mould can only be made adjustable within the small, range determined by the length of the feet at the ends of the lines.
  • This adjustability is, as is known, obtained by. employing the socalled end members or inserted members limiting the length of'the lines, that is tosay, at' the expense of the end .feet'of the lines, which are thus variable from a maximum length to a minimum length.
  • the casting of the lines is most favorable when the end feet have reached their minimum length, so that'the length of the: line and the casting slot in the intermediate plate only differ slightly from one another.
  • this object is achieved by the waste-ejecting device or a waste ejector suitably constructed and arranged for this purpose, which co-operates with the casting mould and the intermediate plate and is controlled thereby during their opposite displacement.
  • the plate-like waste ejector hitherto employed which penetrates from the side ofthe mould intothe cast- I ing slot of the intermediate plate after the s'eparation of the type-line body, cannot be employed for the purpose which'it is desired to achieve according to the invention, particularly as the known waste ejector has the disadvantage that it is very readiiy'jammed, warped, damaged (or destroyed, While it not infrequently itself causes damage to the castingslot of the intermediate plate andmay easily lead to considerable disturbances as a result of splashing of lead or negligence.
  • thewaste-ejecting device which is now employed also for the production of the transverse feet of the lines for the purpose of carrying out the complete casting process and consequently operates in ac cordance with an improved principle.
  • the actual .waste ejector is to a certain extent so arranged in the intermediate plate as a part thereof that it presses with an inclined surface moving perpendicularly with respect to the casting slot against a corresponding inclined surface of the wedge-shaped line waste by which it;is surrounded and thus forces this waste outof the casting slot without itself entering the slot in a direction opposite the casting direotionas' has in the case of short lines.
  • Figure 1 is a view of the wasteejecting device in the direction of the intermediate plate
  • Figure 2 is a plan view of the deviceshown in Figure 1,
  • Figure 3 is a section on the line llI- -lltof Figure 1, showing the parts in the casting position, that is to say, before the commencementof the separation of the line waste,
  • Figure 4 is a similarsection to that ,of Figure .3, but vshowing the parts in the position corresponding to the line-ejecting operation after the ejection of the waste,
  • Figure 5 is a section on the line V- -V of ure 1, showing the parts in the casting position shown in Figure 3 before the separation of the line waste, 7 I
  • Figure 6 is a viewcf the intermediate plate from the side of the casting mould
  • Figure 7 is a perspective illustration of a waste, ejector removed from the intermediate plate, on
  • the intermediate plate 9 is so constructed in known manner that, as may also be seen from 1 Figure 5, its upper part, which is connected to, the upperjaw l of the mould, is elevated in the direction of the mould with respect to the part connected to the lower jaw 3 of the mould, in order thusto form the ledge I2 (see Figure 8) characteristic of the complete casting on the base of the type-line body, 1 during the shearing ofi of the line waste It by the upward displacement of the intermediate plate 9 in the direction of the arrows A inFi'gures 3 and 5.
  • holder l in the direction of the arrow B in Figure 3 lies in a completely coincident position with the-mould slot 6, in order thus to permit the penetration of the line: ejector not shown herethrough the slot If ⁇ in theplate 9 into the .slot 6 of the mould 3, 4 for the purpose of eject ⁇ - 2 I ing the type-line body 1 which has solidified thereing slot 5 of the mould 3;, 4 only, forms a narrow aperture, while the side communicating with the;casting pot is wider (see Figure 5) inorder to facilitate ejectionv of the waste piece ll sheared oil" from the type-line body! in this dimotion.
  • the casting slot I5 of the intermediate plate 9, however, is not, as previously, shortened v at the endsv with respect tothecastingslot 6 of I the mould 3, i, but it permits over. the entire length of thelineand in particular at theline;
  • line ejectors l1 constitute. prismatic bodies,-as shown" in Fig- ⁇ ure 7, each having. av wedge-shaped recess. l8 as shown in Figures 3, 4 andfl.
  • each ejector I'I which in this position lies opposite the casting slot I5 or the recess I8 and covers themould slot 6, is so fashioned that there is formed over the width thereof a complete transverse foot I9 also extending over the entire thicknessof the typeline body I, the upper-surface of'the said transverse foot'lying completely'in a plane with the ployed over the length of-th'e line, the completely I cast foot of a line I shown-in Figure 8 is obtained.
  • the waste ejector I'I extends with a up the position shown in Figure 3;
  • the intermediate plate 9 being shifted in known manner in the direction of the arrowsA in Figures 3 and 5 with respect to the mould 3, 4, the waste ejectors I! cast in the waste I I also move at firstthat is to say, while the intermediate plate 9 is shearing off the entire waste piece II from thetype-line body in the direction 'of the arrows Ain the same direction.
  • the projections 20 thereof thus move from the position shown in Figure 3 inside the recess 2I of the mould jaw 4 until they have reached the position shown in Figure 4 and bear against the upper closed ends of the recesses 2I.'
  • the waste I I is already completely separated from the type-line body] and is situated above the mould slot 6,
  • waste ejectors I I are tapered, 10 for ex'ample by means of recesses or chamfers 22 provided immediately above their wedgeshaped recesses I8 on the edge facingtowards the casting pot, as is clearlyv shown in Figure-'7. Therefore, as soon as the'waste piece It separated from the type-line body I moves upwards into the range of the aforesaid tapers or chamfers 22 during the further displacement of the intermediate plate 9 relatively to the waste ejectors I!
  • clamping springs 23 or the like preferably are provided for holding fast the waste ejectors H in their position corresponding exactly to, the grooves I6 in the intermediate plate 5!, these springs being secured inside the recesses 2I of e the upper mould jaw 4 and gripping therein the projections 20 of the waste ejectors I'I inserted in their correct position.
  • Apparatus for the production of completely cast type-line bodies comprising a mould, a slot in said mouldfor the reception of molten metal, an intermediate plate displaceable along the face of said mould, a casting slot in said plate cooperating with said mould slot for the introduction of molten metal to said mould slot, the cooperating faces of said mould and said intermediate plate on one side of said mould slot being off-set with respect tothe cooperating faces on the other side of said slot, whereby a ledge is formed on the base of the cast type-line body, means slidably mounted on the inner face of said intermediate plate for producing a transverse foot intermediatethe ends of the cast type- -line body, said ioot'extending across the entire 0' thickness of said ca'st body and connected at. an equal level to said ledge, and means for controlling the extent of movement of said slidable means during the displacement of said intermediate plate, for ejecting the waste.
