NEW MOLDING MACHINES FOR FOUNDRIES
The Moscow I iasnaya Presnya Plant has designed and put into series produc-
tion three new molding machines, all pneumatic-powered.
The 265 Molding Machine
The X55 jolt-squecze, straight-straw molding machine has the following new
featuies- a pneumatic arm Tor swinging the 34ueeze head into place, automatic
mechanisms for starting and?.stopping the squeezing and vibrating operations, a
jolt-frequency indicator, and a jolt-height re.ulat-r.
The base of the machine is cast iron. In the center of the base is a cyl-
inder into which the squeeze piston fits. The squeeze piston, in turn, houses
the jolt piston, which is cast in one piece with the jolt table.
The jolt operation is started by turning on a switch, admitting air to the
space beneath the jolt piston. A fiber ring on top of the base, just below the
jolt table, absorbs the shock of the jolt strokes.
Squeezing is begun automatically when the squeeze head is swung over the
jolt table and pressure is exerted on the locking bolt, which secures the free
end of the head to the base. When the desired pressure has been exerted on the
flask, the air is automatically turned off. The squeeze head can be raised or
lowered by adjusting two collars located on the vertical column from which the
head swings.
The draw frame, which has open ends to facilitate molding with longer
flasks, rests on the jolt table, steadied by two guides. It is raised or
lowered by the action of oil under pressure flowing from one compartment into
another and acting on pistons. Vibration starts when the squeeze piston is
raised to a certain height.

Compressed air acts on a small oil reservoir to lubricate the machine.
With supply of loam and removal of tamped flasks fully mechanized, the ma-
chine can reach a productivity of 30 flasks per hour.

The 233 Molding-Machine
The 233 tarn-over molding machine is far superior to foreign machines of this.
type. It consists of two separate units: one, the jolt table and base; the
other, the turn-over and draw unit.
.9he cask-i*on base of the first unit houses the jolt piston, which is screwed
to the jolt table. Rubber shock absorbers are mounted on the base directly below
the table.
The base of the second unit is also cast iron. The turn-over drive piston
is situated on a horizontal c:ic, and is linked by p connecting rod to a cam-
shaft, from tihich two arms reach'to the turr.-over plate, resting on the jolt
table. The arms, which are secured to the plate below its working plane so that
it can handle long flasks, lift the plate, rotate it through 180 degrees and set
it on the draw table. The draw table is fitted with adjustable pneumatic clamps,
and is raised and lowered by a vertical piston. A pair of roller '.3nveyers are
located one on each side of the draw table. Vibrators are attached to the turn-
over plate.
A central control valve and a jolt-frequency indicator are mounted on a
separate column. Also situated on the column are an air filter, an oil reservoir
for lubrication under air pressure, and an air,hose with nozzle.
Productivity under full mechanization of auxiliary services is 15 flasks
per hour.

The 242 High-Duty Molding Machine
The 242 high-duty molding machine is of simple construction, small, easily
operated, and can handle long, narrow flasks. A cast-iron base, set in a con-
crete bed, houses the jolt piston, which is cast in one piece with the jolt
table.
A rod is screwed into an arm projecting from the jolt table, and its lower
end connected to the slide valve which admits air to the jolt cylinder. The
jolt height may be set at from 5 to 15 millimeters by screwing the rod in or
out. Another rod secured to the base passes through the jolt table, preventing
it from turning on a vertical axis. To keep the jolt piston from rising too
far, a hole has been drilled through the side of the cylinder about one fourth
the way from the bottom. A vibrator is attached to the under side of the jolt
table, and a fiber ring below the table serves as a shock absorber.
On each sic:e of the base is a piston. which raises and lowers a draw rod.
At the top of each draw rod is a bridge, at right angles to the rod. At each
end of the bridges there is an arm with a longitudinal slot running down the
center. These arms hold the lift pins. They can be turned 180 degrees, allow-
ing adjustment of the pins to fit the flasks. The two draw rods are connected
by cams to a common shaft, whose axis is at right angles to the direction of
draw. This insures simu'taneous motion for both pairs of pins, guarding
against breaking of the mold.
On one side of the base is an arm on which are mounted the following: the
jolt switch, an air distributor which controls the raising and lowering of the
draw rods and the action of the Vibrator, and an oil reservoir for lubrication
under air pressure.
If the supplying of loam for the flasks. and their removal after tamping
are fully mechanized, the 242 machine can reach a productivity of 30 flasks per
hour.
