5th January 1966 The invention relates to a casting head for pressureless casting machines for applying paint od. The like., which has a first chamber with an inflow, an adjustable discharge slot and an overflow to a second chamber opening into a return. In such a pressureless pouring head, it is necessary that in the pouring head The level of the liquid remains at the same level, regardless of whether more or less liquid is supplied is considered to flow out of the pouring slot so that the liquid in the slot is constantly under the same static Pressure is on. For this purpose, more liquid is fed into the casting head than through its drainage slot can drain off, the excess flowing back through the overflow into the liquid container can. The aim of the invention is to create a particularly useful and yet simple overflow design. This is achieved according to the invention in that the two chambers are parallel to each other and parallel to the dispensing slot and are separated from each other by an overflow wall, and that in the second chamber, at least one known drainage surface inclined towards the return flow or return lines is provided. In the drawing is an example of an embodiment of the invention. It shows F i g. 1 shows a view of the casting head in the direction of arrow A in FIG. 2, Fi g. 2 shows a side view in the direction of arrow B in FIG. 1, on an enlarged scale. The molding head consists of a molded longitudinal body 1 having two end walls 2 and 3, an eccentric shaft 4 and a cover plate 5. The eccentric shaft 4 is supported by means of pins 6 and 6 a in the end walls 2 and 3, which are screwed onto the elongate body. 1 The pin 6 α of the eccentric shaft carries a hand lever 7 which is used to rotate and adjust the eccentric shaft 4 to the inclined bottom of the chamber 9, whereby the width of the dispensing slot 8 is adjustable. The longitudinal body 1 forms with the two end walls 2 and 3 and the shaft 4 two by one Wall 12 separate chambers 9 and 10. In the chamber 9 opens a feed pipe 11 that this chamber connects to a feed pump, not shown. The partition wall 12 is lower than the end wall 13 of the chamber 10, so that it forms an overflow from the chamber 9 into the chamber 10. the Chamber 10 has two roof-shaped ones, one that is horizontal Casting head for pressureless casting machines for applying paint or the like. Applicant: Ulrich Steinemann A. G., St. Gallen-Winkeln (Switzerland) Representative: Dr.-Ing. E. Hoffmann, patent attorney, Munich 8, Maria-Theresia-Str. 6th Claimed priority:
Switzerland of October 21, 1958 (65 245) Plane inclined floors 14 and 15, the un- about an inch in front of the end walls 2 and 3 end so that they leave a dispensing slot 16 free. A drainage plate 17 is placed in each of this delivery slot inserted, on which the excess paint runs off into a return funnel 18 each. So even with less Leakage amount of paint drips from the sheets 17, sheets 19 are provided, by means of which the delivery slots 16 can be narrowed. The sheets 19 have slots so that they can with the Screws 20 can be fastened adjustable. They are bent obliquely in the direction of the drainage plates 17 in order to prevent the paint flowing out against them Conduct sheet metal. The chambers 9 and 10 are covered by the common cover plate 5, which has a handle 21. The cover plate 5 is on the longitudinal edges 5 a and 55 bent and rests on the one hand on the end wall 13 and on the other hand on the eccentric shaft 4. During the operation of the machine, more paint flows through the pipe U into the chamber 9 than through the slot 8 formed by the eccentric shaft 4 and the bottom of the chamber 9 can flow out. Of the Excess flows over the overflow wall 12 into the chamber 10 and runs on the roof-shaped Bottoms 14 and 15 to the drainage plates 17 to through the delivery slots 16 on these plates in the Funnel of the return channels 18 to escape.
