MO LDINGr-MACHINE Specification of Letters Patent.
Patented Sept. 3, 190'?.
Application filed May 3, 1906. Serial No. 315,003-
To all whom it may concern:
Be it known that I, WILLIAM I-I. Woon, oi Allegheny, Allegheny county, Pennsylvania, have invented a new and useful Molding Machine, of which the following is a iull, clear, and exact description, reference being had to the accompanying drawings, iorming part oi this specification, in which- Figure l is a view partly in side elevation and partly in vertical section of a molding machine embodying my invention g Fig. 2 is a section on` the line II-II oi Fig. l; Fig. 3 is a sectional plan view ol the flask and stripper plates; Figs. 4 and 5 are sectional views, taken in planes at right angles to Veach other, of one oi the valves; and Fig. G is a perspective view showing the pattern plate with one iorm of pattern thereon.
My invention has relation to power-operated molding machines, and is designed to provide a machine oi this character which is simple in its construction and mode of operation, and which is especially adapted for use in making deep molds such as have not heretofore been possible to make by power-operated machines.
With these objects in view, my invention consists in the novel construction, arrangement and combination of parts all substantially as hereinafter described and .pointed out in the appended claims.
In the drawings, the numeral 2 designates the fiask, which is supported upon posts 3 which rise from a lower power cylinder 4. The piston 5 oi this cylinder operates a piston rod G, which carries a pattern plate 7, upon which the pattern to be molded is supported. One iorm oi pattern is shown in the drawings, and is marked X. 8 designates a stripper plate, which forms the bottom oi the `iiask 2, and which is provided with an opening 9 corresponding in contour to that of the pattern to be molded. The iiask 2 is removably held in position by means oi the pins l0 carried by lugs or flanges ll at the base of the flask,'and which set into openings in a supporting ring l2, which is secured to the posts 3 around the stripper plate 8. The stripper plate 8 and also the pattern plate 7 are also made readily removable, being secured by screws or other `suitable means, so that they can be readily taken ofi and replaced by a different plate according to the particular pattern which is to be molded.
The cylinder 4 is operated by means of air, steam, or water, preferably air, which is admitted through the valve 13 and pipes 14 leading therefrom to the respective end portions oi the cylinder. A suitable form of valve is shown in detail in Figs. 4 and 5, in which l5 is a turning plug rotatably mounted in the casing 13 and having the admission port I6, the ports I7 which connect with thepipes 14, the exhaust port 18 and the connecting port 19. With the valve in the position shown in Figs. 4 and 5, power is admitted to the pipe 14 leading to the upper end ol the cylinder, while tho lower pipe 1.4 is connected by the port I9 with' the exhaust port 18. In the reverse position of the valve, power is admitted to the lower end oi the cylinder through the lower port I7 and pipe I4, and the upper end of the cylinder is connected with the exhaust through the port 19. Y
2O designates an upper power cylinder, which is supported by an overhead beam 2l, or by any suitable framing. The piston of this cylinder operates the piston rod 2l which carries a presser-plate 22, which is removably secured to the depending post 23. The plate 22 is oi a size to permit it to enter the flask 2, and is formed with an opening 22e, corresponding in contour to that oi the pattern. The cylinder 29 is controlled by a valve 24, which is similar in all respects to the lower valve 1S, Figs. 4 and 5 showing in fact the details of both these valves. 25 is a guide-rod'ior the presserplate working through an opening in the guide-lug 26, secured to the lower head oi the cylinder 20, the purpose oi this rod being to hold the presser-plate in proper relation to the flask.
The head 6 which carries the pattern plate 7 is prei-` erably guided at its corner portions by the posts 3 above described. The pattern plate 7 also carries a portion 7, which forms the pouring gate in the mold. The piston rod 6 is` provided with an adjustable stop collar 6b, by means oi which the extent of downward movement o the pattern plate and pattern may be adjusted and controlled. i
The operation is as follows The flaskbeing placed in position, the cylinder 4 is operated to arrange the pattern X therein. Sand is placed in the liask about the pattern to partially `fill the flask, and the upper cylinder is then actuated to cause the plate 22 to descend into the flask and compress the sand therein. The plate 22 is` then raised, more sand is placed in the flask, and the operation repeated, until the mold has been formed. The lower cylinder 4 is then operated to withdraw the pattern.
It will be readily seen that by means of this machine I can form a mold of any desired depth, inasmuch as successive charges of sand can be placed in the flask and successively compressed, instead oi requiring the entire body to be compressed and packed at one operation, and when the mold has been ormed the pattern can be withdrawn without the introduction of a vibrator, or heating the pattern. p
The various parts of the machine are of simple and strong construction, and are so arranged that the necessary parts may be readily removed and replaced to adapt the machine to mold different patterns.
A further advantage of my invention consists in the fact that with the valve arrangement as shown and described, the pistons ofthe respective cylinders 4 and 20 are cushioned in their movements, being prevented rom moving downwardly with too great rapidity by reason oi the time required in exhausting.
Various modifications may be made Within the scope of the claims without departing from my invention, since 1. ln a molding;l machine, a lower power cylinder, a flask supported thereby, a pattern plate carried by the piston ol" said cylinder, a stripper plate forming the bottom ol' the ilask and having an opening; corresponding in contour to that ot' the pattern to be molded, an upper power cylinder', and a presser plate carried by the piston of said cylinder and arranged to enter the flask; substantially as described.
2. A molding machine having a ilask support, a doubleactingl power cylinder above the support, a double-acting power cylinder' below the support, a presser plate actuated by the upper power cylinder and arranged to enter the llasl: from the top, and a head carried by the piston of the lower cylinder', arranged to carry a pattern through the betteln of the mold; substantially as described.
ln testimony whereof, I have hereunto set'lny hand.
WILLIAM H. WOOD.
