Molding machine

Molding machine definition:

Used in the manufacture of sand mold casting equipment. Its main function is: sand filling, the loose sand filling into the sand box; Tight sand, through vibration compaction, the compaction, the shock pressure, different methods, such as the loose sand in the sand box tight, make the sand mould is necessary in the process of handling and casting strength; Draw, use different institutions to tighten solid after withdrawal of sand mold.

Molding machine development and classification:

Molding machine first appeared in the middle of the 19th century, the early moulding machine is a kind of simple manual compaction with a draw, then using compressed air as shock compaction and dynamic compaction sand. In 1890 the shock moulding machine, make modelling efficiency and precision of sand mold have been improved.

Molding machine according to the method of tight sand compaction can be divided into different type, vibrated type, pressure type, squeeze moulding machine and the sand slinger.

Molding machine component unit and features:

Molding machine consists of fuselage, stripping mechanism, shock compaction mechanism, jib head parts and components such as pneumatic piping system.

1. The fuselage artifacts for a solid hollow frame, the upper supporting arm head part, pressure hooked fuselage make real-time transfer arm strength by the fuselage, under the fuselage with shock bolting together, jib head part, head is fixed on the can rotary arm, head has a spiral elevator can be adjustable according to the height of sand box to head to the distance of the sand box

2. Turn the arm by hand valve control cylinder piston movement back and forth, positive arm and arm movements.

3. The die structure from two die cylinder, connecting rod, balance shaft, draw, draw pole etc, draw cylinder startup drive the connecting rod, balance shaft, draw four plunger jacking sand box draw at the same time.

4. Shock compaction structure. Use spring microtremor pneumatic compacting structure, increases vibration compaction hammer. Draw will be vibrated when clamping cylinder lock cylinder body, when clamping cylinder to loosen.

5. Pneumatic piping system: input the compressed air, the air filter to remove water from compressed air and impurities, and then through the oil mist lubricating oil injection and supply pneumatic components and institutions, the console machine action by hand valve.

6. Air supply and lubrication. The machine is made up of gas source for energy and oil lubrication to implement the work. Size of the inlet pressure and oil amount respectively by the pressure reducing valve and valve to adjust. Gas source through according to the principle of siphon oil mist detector will oil suction pipe, lubrication mist into the piping system.

Molding machine is reasonable use:

1, abide by the molding machine and core-making machine general operation procedures.

2, molding machine, stripping, plunger, or must be smooth and synchronization, otherwise, notify the maintenance personnel to repair.

3, molding machine pressure real-time, sand bar bogie should rotate smoothly, don't too hard, operation impact.

4, the operator must pay attention to the mold are in good condition before, during, and after production, mold and core mold positioning pin is necessary.

5, molding machine operation personnel should be centred.

After the completion of the 6, molding machine box, should according to the provisions of the process by pouring mold crane moved to formulate point (line). Well organized, and weight or clamp lock box. Miscellaneous must indicate a mark.

7, molding machine sand box are not allowed to pile up too high, generally no more than two meters, the tool must be neatly stacked, prevent accidents.

8, when using a blowtorch, should pay attention to safety, prevent fire, using the line must be under 36 v low voltage lamp bulbs, disable more than 220 v high pressure lamp.

9, molding machine using driving should first check whether the spreader is good, when the lifting hook should be fastened chain straightening, no tilt hanging and overload lifting.

10, is strictly prohibited under the sand box operation mode operation. Large sand box out of the box, turn mat boxes square objects must be used when appropriate.

11, molding machine using sand box must be firmly, Mr To complete no crack and bending phenomenon
