PERMANENT MOLD-COOLING- DEVICE.
Application fil-ed November 7, 1924. Serial No. 748,315.
The object of this invention is to provide im roved means for cooling the permanent mo ds of a rotating molding machine.
Figure 1 shows a plan view of the device. Figure 2 shows a cross sectional elevation on the plane 22 of Figure 1.
Figure 3 shows in elevation the middle portion-of Figure 1. v
Figure '4 shows a cross'sectional on the plane 4--4 of Figure 5.
Figure 5 shows in elevation a detail of one of the cooling nozzles.
In the figures, A and B are two conduits which serve to supply the cooling fluid. These conduits are formed in the arcs of circles and arranged concentrically with the Esath of the rotating series of molds C- C C C. and E are the entrances to the conduits B and A, preferably located in the center g0 thereof. F is the common entrance to D and E. G and H are throttle valves located in the connections between F and E and F and D respectively.
J and I are the cooling nozzles mounted on the conduits A and B, as shown in. Figures 4 and 5. Each of the nozzles I and J are connected to or formed integrally with a strap K -L connected by a bolt M. The conduit B is provided with openings N corresponding to the nozzle I. These openings are elongated .or oval shaped so that the nozzle I may rotate, as shown in Figure 4. This detail may be omitted, however, where there is an "intention of changing the type of the mol 0, but where dilferent molds are to be used it is desirable to be able to adjust the direction of the nozzles I and J to take care of the difierent cooling conditions which arise with different types of molds.
Operation.Air is admitted at F and distributed .to the two conduits A and B by suitably adjusting the valves H and G so that the desired amount of cooling air is supplied to each row of molds. The air is distributed through the pipes A and B and discharged through the nozzles I and J against the backs of the rotating molds C.
elevation of molds,
Obviously if the molds O are arranged to travel in a straight line the cooling conduits A and B will be arranged also in a straight line to take care of the difierent conditions as they prevail.
What- I claim is:
1. In combination with a travelling series of molds, a stationary air conduit extending parallel to the path of said molds, a plurality of nozzles mounted upon said conduit and discharging in the direction of said molds, means for delivering cooling air to said conduit.
2. In combination with a travelling series of molds, two stationary air conduits extending parallel to the path of said molds and located on each side of said path, a plurality of nozzles mounted on said conduits adapted to discharge against said molds, common means for admitting cooling gases to said conduits, means for controlling the distributionof cooling gases between said conduits' 3. In combination with a travelling series of molds, a stationary air conduit extending parallel with said series of molds, a plurality of nozzles angularly adjustable u on said conduit discharging upon said mol s, means for admittlng a cooling gas to said conduit.
4. In combination with a rotating series a stationary air conduit formed into the arc of a circle concentric with the path of said rotating molds, a plurality of nozzles mounted upon said conduit and discharging against said mold, means for delivering cooling air to said conduit.
5. In combination with a rotating series of molds, a pair of stationary air conduits arranged on opposite sides of the path of said rotating molds and formed into the arcs of circles concentric with the path of said molds, a plurality of r' zzles mounted upon said conduits and discharging upon opposite sides of said molds, means for delivermg a cooling fluid to said conduits.
In testimony whereof I afiix my signature.
JOSEPH L. DOSTAL.
