3 Claims.

It has already been proposed to employ means for cooling the casting molds of matrix composing and line casting machines, the cooling water having usually been supplied to the mold-disc through the pivotal stud or shaft thereof. With these constructions it was not possible to secure an entirely watertight connection, and the object of the present invention is to overcome this disadvantage, and to provide a construction in which 19 the water circulation will be so arranged that it can be kept securely watertight.

For this purpose, according to the invention, there is provided a stationary ring-shaped body, preferably secured to the mold disc carrier or slide, and making watertight contact with the mold disc, the said body forming together with the mold disc, two annular channels which communicate respectively with inlet and the outlet pipes for the cooling water on the one hand and on the other hand, with tributory conduits extending preferably right through the mold disc towards the casting molds.

The accompanying drawings illustrate by way of example, one constructional form of the invention, and in these drawings:

Figure 1 is a vertical section through part of the mold disc, taken on the line |I of Figure 2, and

Figure 2 is a face view of the mold disc as viewed from the left of Figure 1, with parts at the left and right hand sides in vertical sections taken respectively on the lines .r.r and 11-31 of Figure 1.

In the drawings a is a portion of the mold slide or mold disc carrier which supports the pivotal stud b of the mold disc 0. The mold disc carries the casting molds d, d For purposes of cooling by water, a ring e connected to the mold slide a and to the water inlet and outlet pipes encircles the hub c of the mold disc 0. In the mold slide a, two openings are provided for the passage therethrough of the water supply and outflow pipes i The pipes f and I extend into the ring e wherein they communicate respectively with radial ports or channels g, g which are closed at the outside of the ring by threaded plugs, and which communicate respectively with annular grooves h, h in the periphery of the mold disc hub 0 These annular grooves h, 71 are in turn connected respectively to conduits 2', i extending parallelly with the mold wheel axis in the hub c and connecting respectively with outwardly directed conduits k, k terminating behind the respective molds d, d in ports m, m The molds themselves have each two channels 0', 0 each in open communication with a transverse port m, or m opening into a channel 10, extending around the respective mold slot. The cooling water is supplied through the pipe 1. It runs thence through the. port g into the annular groove h, and from there successively through the channels 2, k, m, 0', into the channel 1 passing round the respective mold slot. At the other end of this channel p, the water flows successively through the conduits m k i through the annular groove 11. and the radial port 9 and out through the channel f As the grooves h and h extend completely around the mold disc hub 0 any desired number of conduits 70, 70 can branch outwards according to the number of casting molds carried by the mold disc 0. In the example illustrated the representation is confined to two, but obviously more or less than that number may be used. The conduits in the mold disc 0 and in the molds (1, d are preferably arranged as indicated in the constructional example represented, but it is obvious that instead of the channels being formed within the mold disc and the molds, pipes or the like may be used. If considered expedient, a plurality of adjacent conduits may be arranged around the molds to produce a greater cooling effect; in such a case these conduits might be arranged either behind or beside each other.

The joint between the mold disc and the ring e is made watertight preferably by means of packing q and q In the constructional example illustrated the annular grooves h, 71. are formed on the periphery of the hub c of the mold disc. Alternatively, they could be upon the vertical face of the mold disc contacting with the front face of the ring 6, or be formed partly or entirely in the ring 6.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:

1. In a slug casting machine, the combination of a mold slide, a stud fixed thereto, a mold disc rotatably mounted on the stud, said mold disc be; ing equipped with channels extending through the disc and leading to a mold, the channels communicating with separate annular grooves open at the exterior of the mold disc, and a member in watertight contact with the mold disc, said member being equipped near its opposite edges with water sealing means and formed intermediate the sealing means with separate openings in register each with one of said annular grooves and communicating with fixed supply and exhaust pipes, and

said member having a joint surface extending at right angles to the axis of the mold disc.

2. In a slug casting machine, the combination of a mold disc equipped with a plurality of molds and formed with a rearwardly extending bearing hub, a mold slide, a stud fixed to the mold slide and on which the hub of the mold disc is rotatably mounted, channels formed in the mold disc leading from the hub to the molds and communicating with annular grooves formed'in the cylindrical exterior surface of the hub, and a stationary ring arranged in water-tight relation to the mold disc, said ring being equipped near its opposite edges with packing rings and formed intermediate the packing rings with passages communicating each with one of said annular grooves and with a supply or exhaust conduit, as the case may be.

3. In a slug casting machine, the combination of a mold disc equipped with a plurality of slotted molds and formed with a rearwardly extending bearing hub, a mold slide, a stud fixed to the mold slide and on which the hub of the mold disc is rotatably mounted, channels formed in the mold disc leading from the hub to the mold and arranged for the continuous circulation of a cooling medium around the mold slots, a pair of noncommunicating annular grooves formed in the cylindrical exterior surface of the hub, and a stationary ring surrounding the hub in water-tight relation thereto, said ring being equipped near its opposite edges with packing rings and formed intermediate the packing rings with passages communicating one with a supply conduit and one of the annular grooves and the other with an exhaust conduit and the second annular groove.
