\ Application ined July 6,
My invention ,relatesv to new andfuseul improvements in molds, and one object 1s to provide a mold-.whichcan be readily closed and opened preparatory to forming a casting and discharging the latter.
Another object is to provide a mold with mechanism for facilitating discharge of the' finished castings. :j
Other objects will hereinafter appear, and in order that the invention maybe fully understood reference. will now be had to the accompanying drawings, in Which;
Fig. 1 is a planview ofthe moldwith the sections thereof inv closed position and` the handles partially broken away.
Fig.` 2 is an end elevation of the moldwith the handles partially broken away. n
Fig. 3 is an irregular cross section on line 3-3 of Fig. 1.
Fig. 4 is a slightly enlarged horizontal section on line 4-4 of Fig. and with the mold in inverted position. p
i Fig'. 5 is an invertedend elevation of the mold in open position.
Fig. 6 is an enlargedcro'ss section offa plungerI and a core pin `employed in carrying out the invention,
In carrying out the invention I employ mold sections 2 and 4 having registering' chambers 6 and 8, in which the castings are formed. The sections 2 and 4 are provided at their upper portions with registering gates 10 and 12, which communicate with the chambers 6 and 8, respectively. j
Guide means in the form of rods 14 and sleeves 16 are provided for operably connecting the sections 2 and 4 and guiding the latter as they areopened Vand closed. The rods 14 are slidably mounted in the sleeves 16 and secured to the ends of the section 2, while the sleeves 16 are secured to the ends oi the section 4. The rods 14 are provided at their free ends with suitable heads 18 for actuating a cross head 20 slidably mounted upon said rods 14.
22 designates a pair of brackets secured to the longitudinal outer side of the section 2 and provided with horizontal slots 24 in which a fulcrum 26 is slidably mounted. Said fulcrum 26 is provided with a pair'of core pins 28 projecting through the section 2 and reinforced with bushings 30 which prevent the molten metal from Howing into the openings through which said core pins 28 project.
32 designates a lever rockably mounted upon the fulcrum 26 and equipped with a 192e.l serial No. 120,695.
rigidly mounted handle The free end of the lever 32 is pivotally connected at oneend of a pair of links 36 whichv are pivotallycon.- l
nected at their oppositeend toa-,lug -38 secured to the bottom or the section, 4, The lever 32 is'yieldably held from rockinguponV its fulcrum 26 byymeans of a coilspring 40 secured at one end'tosaid lever 32 and at' its opposite. end to thereducedfend cfa plate 42 secured to thellongitudinal outer side-ofthe mold k2.
j The section 44 provi-ded with.V xedly; i
mounted handle 44 extending freely. through4 anrv opening v46 fin the cross` head 120'. f The i handle 44 is provided witha transversey pin 48 to which a pair of core pins 50 are secured.
' Thecore pins 50 projectithrough the section 4 and are provided near their innerends with semicircular bushings 52 which slidably engage thcsemicircular portions 54 of a pair of tubular plungers 56 through which said f core pins 50 extend. The bushings k52 'and the semicircular. portions 54 of the plungers 56 prevent thev molten metal from flowing into the openings through which said plungers 56 extend into the section 4. The plung-l ers 56 are held against the cross head 2O by coil springs 58 which are interposed between theadjacent side of the section 4 and heads 60 at the outer ends of said plungers56.
62 designates a plunger extendingV into the lower portion of the section 4 and prorvided at its outer end with a head 64 which is held against the cross head 20 by a coil spring 66 interposed between said head 64 and the adjacent side of the section4. Norinally the cross head 2O is held by the outward pressure of the plungers 56 and 62 f against a stop 68 secured between 4 and the lug 38.
In practice the metal or other material to form the casting is poured into the mold while the sections 2 and 4 are in closed position. The mold is then inverted and opened by raising the handle 34 to the position shown by Fig. 5. Raising of the handle 34 rocks the lever 32, causing it to push upon the links 36 Vand thereby force the sections 2 and 4 apart the section the heads 18 of the rods 1,4 to e gage and draw the cross head 20 towards t e section 4, thereby forcing the plungers 56 and 62 in Wardly against the actiqp of the spri gs ,58 and 66, respectively, so t at'they will eliver the casting from the section 4. After theA casting has been delivered pressure on the handles 34 and 44 is relieved suliiciently to permit the springs 40, `5 8 and 66 to close` the moldl The springs' a-nd66 also force the respective plunger-s 56 iand 62 loutwardly and they in turn force the cross head2() outwardly until cheeked by the stop 68,.
From theforegoing description it is ap` parent that I have provided a rnold of larbe capacity due to the: rapid mannerwin which it maybe ope ed and closed, andwhile have shown an describedv the preferred construction, com linatiol'l'and arrangement of `parts reserve all rights to such changes and modifications as operly fall 4Within the spirit and scope 0 the invention as claimed.
Having` thus described my invention, what I claim and desire'to secure by Letters Patent, is: A
l. In an invertible mold O f the character described, two ollainbered sections, sleeves fixed to one section, rods fixed to the companion section and slidably mounted in said sleeves a cross head slidably mounted upon the rods, plungers operably mounted in one section, means on the rods for causing said Cross head to force the plungers inwardly when the sections are opened, and spring means for forcing the plungers (ultwardly when the sections are closed.
2. In a mold of the character described, mold sections, means operably (connecting said sections for holdinor the lat-ter in proper relation to each other W en opened or Closed, a fulcrum slidably associated with one section, a core pin secured'to said iulcrum and extending into the associate section, a lever mounted upon said fulerum for causing the `latter to rnove said oore pin outwardly and inwardly when the sections are opened and closed, a link connecting said lever and the companion section, and means for actuating said lever to effect the opening and closing of the sections.
In testimony whereof I aliix my signature,
CHARLES A. Woon
