The Programmable tilt system is designed for applications that require variable tilt rates. Variable tilt rates can increase your profitability by:

The system uses our time proven hydraulic power unit. Refer to Hydraulic Power Units pagesfor standard unit details. The system uses a PLC control and a touch screen operator interface. The unit can be configured to fit almost any application, but most systems are six valve. Normal circuits include tilt, ram, front eject, core, casting catcher in/out and casting catcher vertical movement. The proportional tilt valve is PLC controlled with feedback from a trunnion mounted potentiometer or optional ultra sonic sensor on the casting machine. Tilt rates are programmed by drawing the desired ramp curve on the touch screen with your fingertip. The PLC can store up to eight different ramps under a four digit code. All manual functions are included on the touch screen and touch screens are available in monochrome or color.

With the use of a retaining bolt and specially designed shoulder you are no longer faced with the problems associated with a press fit type of leader pin.

With diameters from .500" to 1.000" these pins are designed to be used in the construction of both small and large permanent molds.

Please refer to the Typical Permanent Mold Assembly sheet and individual catalogue sheets and individual catalogue sheets for all your mold component requirements.

Pouring cups are made from 30 class gray iron. The pouring angle is 45, so that the mold filling is complete at 45 of machine tilt. Whether used with programmable tilt or standard tilt, these cups produce quality permanent mold castings.

These heat-treated, allow steel, carrier bolts will provide long lasting alignment of the mold ejector plate, thus assuring accurate ejector pin alignment and eliminating the problems involved when ejector pins carry the weight of the ejector plate.

Please refer to the Typical Permanent Mold Assembly sheet and individual catalogue sheets for all your permanent mold component requirements.

Do you have existing molds that run on an Autocast mount rail machine? CMH can adapt our time proven #6H to run these molds with more stroke and ejection clearance than the original Autocast machines. See #6H, traditional tilting machines, for machine specifications.

Replacement mount rails and spacers

* Mold mount rails and keys are designed for mounting permanent molds in- 30 x 30in (762 x 762mm)- 36 x 36in (914.5 x 914.5mm)- 42 x 42in (1066.8 x 1066.8mm)- 48 x 60in (1219.2 x 1524mm)tiltpour casting machines.

casting catchers increase production while reducing operator load. They are a available as manual swing-in or fully automatic powered swing-in. The table height is optimized to allow the operator to inspect a casting while the next casting is cooling in the mold. The system utilizes minimal floor space and allows one operator to do the job safely with minimum effort. Tie bar extensions are required when using a swing-in casting caster.

The table height on all swing-in casting catchers is adjustable in 1.5 inch increments.

Rotary action of the powered casting catcher is from a hydraulic rotary actuator. The stroke of the vertical cylinder is eight inches.

Times are tough for permanent mold foundries needing to replace a tilt machine. Have you considered having HALL do a complete factory remanufacturing of your existing tilter or perhaps factory rebuilt used equipment?

Here is an example of one of our customer's factory remanufactured 3L machine (right). We salvaged the steel and replaced worn components with new cylinders, bearings, bushings, way bars, and slide wear strips.

The Rotary Casting Machine advances permanent mold casting technology another step and makes it the most profitable approach for the modern foundries today. This high production, completely automated system can meet your needs for large volume applications. We incorporate up to 12 of our standard casting machines (#2H, #3HS, #6H or RT machines) on one rotary table to reduce cycle time in each station to as little as 20 seconds.

As an example, based on our 8-station 2H Rotary Table, we have calculated that eight seconds is necessary to index the table between stations without inertial forces affecting feed characteristics of castings. Assuming a three minute (180 second) cooling cycle, this rotary system will theoretically produce 120 cycles per hour.

At 83% of theoretical, it would be 100 machine cycles per hour. At 100 hours per week, this calculates out to 10, 000 machine cycles per week. If there are two cavities, it will produce 20, 000 parts week . This will give a total production of nearly one million parts per year!

• Indexing system uses a Geneva drive with an epicyclical gear motor and a variable frequency invertor. This allows smooth indexing speed adjustment.
• Control utilizes the Allen Bradley SLC series PLC and a color touch screen.
• Easily interfaces with ladler or casting catcher.

CMH Manufacturing Co. introduced a new twist on the reverse tilt process at the CastExpo. Our static cylinder head machine inspired the development of the HALL RT2H. The machine has twin opposing rams and a lower cylinder that can be programmed as a pull or an ejector. The ram cylinders each have 15 stroke and the distance between the platens when both rams are open is 42 and with both rams closed the distance is 12. The maximum clamping force is 29, 000 pounds. The stroke on the pull/eject is 4 with pulling force of 16, 200 pounds and pushing force of 18, 500 pounds. It is available with standard or proportional tilt.

Hydrogen is our friend or foe. Depending on the type of casting you produce, hydrogen absorption by molten aluminum can be helpful or harmful.

With the Vac-U-Check you are assured a quick, simple, economical, and accurate method of monitoring the hydrogen level in your melt.

A vacuum solidified sample exaggerates the hole size, making the analysis of gas in the sample easy to determine by visual methods or by using the specific gravity formula.

The use of a Vac-U-Check unit is simple. Dip a 1/4 pound molten aluminum sample from your furnace. Place the sample in the vacuum chamber for solidification. After the sample is cool, saw it in half for a visual inspection or weigh the sample in air and water to determine the true specific gravity.

Should your castings be at the premium level, a minimum amount of gas is required. If you are producing a commercial casting, a small amount of gas can be helpful in reducing shrinkage, thus simplifying gating, risering, chill usage, and improving yield. See the samples above and note shrinkage difference in the sample solidified in air.

Features

In keeping with our continued commitment to meet the needs of our customers and offer accessories that lend efficiency and increase production rate, we have developed our robot casting catchers. Ejected castings can be removed from the upper or lower mold halves with precision and placed on our indexing cooling conveyor, dropped into a tote box or a quench tank, depending on your requirements. Though the robot was originally designed for our rotary machines, it can interface equally well with any of or individual machine applications. Our robot is operated by an internal programmable controller and all strokes are set with adjustable limit switches. Each cylinder is cushioned on both ends providing a smooth transition of movement. The standard sequence of operation is to extend into the mold, lift or catch the casting, retract out of the casting machine, rotate 90 degrees, lower, tilt the forks to slide the casting onto the indexing/cooling conveyor and return to start. The conveyor indexing rate and spacing are adjustable with a timer. Optional applications for this robot include core setting, transfer to and from other processing equipment, etc. An optional mechanical hand is also available.

Tilt pouring reduces turbulence as molten metal enters the die cavity, provides shorter cycle times, and requires less metal for feeding systems. Aluminum castings produced in metal molds have a tighter dendrite structure than castings produced in other processes. In addition, aluminum castings are harder and have better pressure characteristics. Value added options, such as sand cores or cast-in ferrous inserts are quite simple.
