Definitions

  • the invention relates to machines for lilling molds and more. particularly to that type in which sand isv projected at high speed into the flasks.
  • One 'object of the invention is to provide improved means for supporting the sand projector or slinger, so lthat it can be easily moved over flasks and particularly in those instances where the longitudinal movement of the projectorl necessary to project sand into all portions of the mold, is comparatively short.
  • Another object of the invention is to pro-ride improved mechanism cooperatively arranged With the movable projector for carrying ⁇ iasks to and from the projector.
  • FIG. 1 is a side elevation of a machine embodying the invention
  • FIG. 2 is a section taken on line 2-2 of .Fig l. Fig.
  • Figure 7 is a' detail View. partly in 'section.
  • This breekt-itv comprises an upper section 12 and a lower section 13 between which are confined suitable ball-bear ings'14 formingan anti-friction bearing for supporting the bracket 11, so that it can be freely rotated in a horizontal plane.
  • Sections 12 and 13 are secured together by bolts 15 and arev formed so as toenclose 'bearings 1.4 and the upper end of column l0 and to retain the bracket on thecolumn.
  • the base 1601i column l0 is fixedly secured to the molding room lioor by bolts 17.
  • the machine comprises a jib or arm 36, a sand projector including a casing or stator 38 and a rotor 39 provided with a combined projector and shear-blade 40, a shaft 41, ⁇ to which the rotor is secured, a tubular member 37throughwhi ⁇ chshaft 41 extends,.and an electricl motor 42, the casing ot' which is fixed to arm 36 and to the rotor of which (not shown) the projector 41 is secured.
  • An endless belt 46 is adapted to convey sand received from an overhead stationary chute ⁇ 44 and to deliver it to the projector 4casinol 38 and to the rotor 39.
  • This belt 46 is carried by a drive-pulley 47 adjacent the electric-motor and an idler pulley48 adjacent the projector casing. Both of these pul leys are mounted ⁇ -to move with arm 36.
  • the idler pulley 48 1s supported by bearings 48 which are fixed to a yoke 38 which rigidly connects the casing 38 and tubular armrneinber 37.
  • Drive-pulley 47 is mounted on a stationary shaft 58 which is supported by a bracket 59 and a gearcase 57. both of Whichare tixedly secured to the sides of a housing-49. The latteris lixedly secured to member 37 of arm' 36 and to the casing of '85 motor 42, so that the projector, motor ,and
  • 'sand-feeding belt may be shifted together, as hereinafter more fully s'etforth. 'Pulley r47. which drives the sand-feeding belt 46,
  • bracket 65 rigid with stud 64, bowed around arm 36 and ex tc ,ding under housingl 49; two pairs ot parallel suspension links 66, the upper end et each link being pivotally sustained by a bolt 6T which is supported in a standard 68 rising from and rigidly secured to the supporting bracket 'l17 which is pivoted to swing horizontally on the main supporting column lO; and eross-rods 69 carried by the lower ends of said pairs ot links respectively and extending through lugs 65 on bracket so that bracket 65 will be movably sustained by links 66.
  • a roller 80 is mounted on housing 49 and is adapted to ride in an arcuate groove 8l :termed at one end ot bracket 65. This roller and groove connecj tion permits the arm to be swung;f about the asis ot stud 64 and prevents excessive 'strains on and breakage of said stud from which the arm and parte carried thereby are suspended.
  • arm 36 is suspended from icket 65 and stud 64, so that the projector .li be positioned rto cause the sand to be ⁇ v'ejected vertically downward.
  • ln iilling ifa with wide retaining bars ⁇ it is desirailc to slightly angle the line of delivery to A 'eet the wads and pack sand under the han or undercut spaces.
  • the suspension l nger GQ permits the operator to rock arm around the horizontal axis of stud 64 so that the projector casing, motor 4Q. ho f ng 49, belt 4G and chute 60, all of nich are cooperatively mounted on said arm.
  • the projector' supporting-arm 36 being supported by the horizontally rotatable fh is parallel with the axis ot arm S6 ⁇ bracket ll, can be swung horizontally. around the axis of colmn 10, Yso the opel ator can shift the projector laterally with'- out varying the angle of delivery. ot the sand when desired and to project sand into ditterent portions lengthwise of the flask, by grasping handle 6l and swingingY the arm, bracket 65, suspension link G6 and bracket ll horizontally around column l0.
  • this suspension linkage beine' composed ot parallel nairs of links, permits the projector to be shifted crosswise of the flask without substantial variations in the angle of deliverv of the sand.
  • a further characteristic of this suspension linkao'e is that the projector, when it is normally positioned centrally over the a'sk. will. after it has been shifted radially inwardly1 or outwardly, automaticallv move back hv gravity to its normal central position. thns relieving the operator ot the necessity of retractiner the projector to said position.
  • a turn-v table 90 preie'ablv made ot' a sheet ot' boiler-plate. is mounted to rotate concentrically around the axis ot column 10.
  • A. ball-bearing' 91 supports the inner portion of this table and a series ot' rollers 92 Amounted in ln'acliets 955 respectively support the outer margin oi the turn-table.
  • a stationary angle iron ring 94 is fixed to the ⁇ floor and an angle iron ring( 95 is fixed to the underside oi" turn-table 90. so that the vertical flanges of these rings will lap one another to exclude sand from the space hetween the turn-table and the floor.
  • Flask ⁇ carriers 96 oit any suitable construction and in desired number are secured to the turn-y table and are rotatable therewith, so that mounted ona bracket lOl fixed to column l0; arpinion 102 on 'the motor shaft; a gear 103 meshingr with said pinion and fixed to :t shaft 104 also mounted in said bracket; a bevel-pinion 105 fixed to shaft 104 and driven by tcrear ⁇ 103; a bevel-gear 106 meshing ⁇ with pinion 105 and fixed to a 'vertical' shaft 107 Whicn is also mounted in bracket 101: a pinion 10S fixed to the lower end of shaft 107; and an internally toothed gearrinp' 109., which is fixed to the upper tace of turn-table 90.
  • a housing' 110 encloses this gearing and motor and is also extended to cover the rear-ring; 109 to er-tclude sand therefrom.
  • This mechanism eX- emplifies an electric motor and reducing:r gearing for constantly driving' the turntable 00 :tor feeding; flasks to the projector.
  • the invention exemplifies a molding machine ot the sand-projector type. in which a single projcoter-carrying arm is movable pivotally and lonnitm'limillv'so that. in some instances. a pair of pivotallv connected arms maybe dispensed with. Also a structure ot this character in which the single arm is carried by suspension links which permit longitudinal shitt ot" the arm and which are automatically restored by gravit-y to a central position.T The invention also exemplifies a machine ot this type in which the projector carrying' crm swings concentrically 'with the flrnks on a turn-table. The machine. as a whole' mal-tes it possible to till. flasks by the m'oiectinf;method with great facility and with a low labor cost.
