DIE CASTING MACHINE Nov. 24,l 1931.
Filed Jan. 9, 1950 Z3 2 I v 3 ang Patented Nov. A24, 1931 UNITED ls'rA'ras PATENT OFFICE' FRANCIS T. TIKALsxY, CE LA GRANGE, ILLINOIS, AssIGNoE. To WESTERN ELECTRIC I COMPANY, INCoRPoEATED, or NEW YORK, N. Y., .a CORPORATION 0E NEW Yom:
DIE CASTING MACHINE lApplication led January 9, $30.' Serial No. 419,660.
This invention relates to rdie casting machines, and lmore particularly to casting pumps forming a part of such machines.
In certain-types of machines for casting metal in metallic molds or dies, a movable pump or gooseneck is provided which, by the operation of suitable actuating mechanism,
is dipped into .a pot of molten metal and thereby filled with molten metaly to be cast,
and the pump or gooseneck is then moved lng member 18 which is in turn pivoted to a the pump into the sprue and thence to the dies. It is essential totheeicient operation of the pump that both nozzles register simultaneously and accurately with theirrespective glands in spite .of expansion and contraction of the atures. l
An object of this invention is to provide a casting device fora die casting machine which may be accurately alined with its associated parts to insure proper movement of the molten metal to the die.
Inone embodiment of the invention, an air-receiving nozzle is mounted eccentrically upon a hollow threaded shank which engages in a correspondingly threadedl bore inthe pump in such manner that the distance between the air-receiving nozzle andthe metalejecting nozzlemay be increased or decreased by rotating the shank relative to the bore.
Further objects of the invention will be apparent from the following description, taken in connection with the appended drawings, in which Fig. 1 is a fragmentary longitudinal view, partlyl in section, of a die casting machine embodying the invention, and
Fig. 2 is an enlarged sectional view of the 'air-receiving' nozzle.
The die casting machine shown in the to .a stationary bolster plate 11 4to which a parts dueto changing temperstationary die section 12 is secured, a movable die section 13 being shown in cooperative relation'thereto. A supply of molten metal 14 to be cast is contained ina melting pot 15, into which the pump 10 is dipped and from which it is raised by suitable actuating means o'f known construction comprising a horizontal bracket 16 which is secured to the pump. The bracket 16 is supported by mechanism which includes a link 17 pivoted to an adjustbracket 19 iiXed to the machine frame and adjustable by means of set screws 20.
The vpump 10 is ofy a gooseneck type and is provided with a' chamber 21 for molten metal, and with a metal-ejecting nozzle 22 adapted to be dipped below the level of the metal 14 so that the chamber will ll by gravity through the nozzle. The nozzle is designed to register, when the pump is in a casting position, with a gland 24, of any suitable construction, which constitutes the sprue leading to the dies formed in die sections-12 and 13. The upper portion 23 of the pump comprises an air conduit 26 which communicates with chamber'21 and terminates in an enlarged threaded bore 25 in which the correspondingly threaded tubular shank 28 of an air-receiving nozzle 30 engages, the shank 28 being eccentrically related to the bore of the nozzle. Nozzle 30 is shaped to seat in a recess or nipple 32 which is formed in the upper portion of plate 11, and when so seated registers with an air duct 34 which is connected to any suitablesource of compressed -air (not shown).
and it will be readily understood that rota' tion of nozzle 30 will result in increasing or decreasing the distance (between thev air- 'recei-ving nozzle 30 and the'metal-ejecting nozzle 22, thereby compensatlng for expansion and contraction of the pump 10 and its associated parts due to temperature c hanges. Such 'adjustment may be made during the operation of the machine, and enables the operator to maintain the registry of nozzles /f/-these adjustments may be made concurrently,
` in order to provide proper registry of thev the nozzle may be said to be adjustable in three planes. The nozzle '30 is held in its adjusted position by means of a lock-nut 38 which is threaded on the shank 28.
In the operation of the die casting machine,
the metal-ejecting nozzle 22 is accuratelyy alined with gland 24 by loosening one of the screws 20 and tightening the other to'raise or lower the pump'lO relative to the frame of the machine. Nozzle 30 is then adjusted by loosening lock nut 38 and rotating the nozzle 30 until it registers with gland 32, whereupon the lock nut is tightenedto yhold the nozzle 30 in its adjusted position. y
While the invention has been described with particular reference to a specific embodiment thereof, it may be embodiedin various other forms, and is not li'mitedexcept bythe language of the following claims. Thus, it will be apparent that the nipple 32 may be made adjustable rather than the nozzle 30,
nozzles, as well as such other changes as fall within the spirit of the invention. l
What is claimed is:
1. In a die casting machine, a movable pneumatic pump, a stationary member designed to supply motive fluid to the` pump, and a motive fluid receiving member comprising a nozzle portion and a tubular portion eccentricallyf related to the nozzle portion to permit adjustment of the nozzle toward and away from the stationary member.
with an air-supplying member, said air-receiving member comprising a nozzle portion and a tubular portion eccentricall related to the nozzle portion and thread d'y engaging the pump.
Y In witness whereof, I hereunto subscribe my name this 31st day of December A. D.,
FRANCIS P. TIKALSKY.
V2. 4In a die casting machine, a movable pneumatic pump, a member designed to supply motive fluid thereto,'and a motive fluid receiving member comprising a nozzle portion and a tubular portion eccentrically re- 4 lated to the nozzle portion threadedly engaging the pump to permit adjustment of the nozzle portion toward and away from the first mentioned member.
3. In a pneumatic pump for a die casting machine, a member for receiving motive -luid comprising a nozzle portlon and a tubular lportioneccentrically related to the nozzle l' en portion and threaded into a bore in the Ipump to permit adjustment of the nozzle relative t to the pump in three planes.
4. In a pneumatic pump for a die casting machine, a metalejecting nozzle designed to .register with a stationary member, and an airreceiving member designed 'to register,
