Procedures for the use of green sand molding machine and molding line

The green sand moulding machine fault detection encounters air filter gas blockage. Because the vacuum pump works to generate some water, the filter element in the air filter gas is blocked by adding some foreign matter in the pipeline for a long time. The pressure gauge looks at this time. The pressure is not small, but the air flow is not enough, so that the green sand moulding machine can not be used as usual. In order to use the green sand moulding machine and its moulding line normally, the following points should be observed:

1. Check the general rules for the use of green sand moulding machines.

2. When the green sand moulding machine is launched, the ejector rod is stable and synchronized, otherwise, the maintenance personnel are notified to repair.

3. The green sand moulding machine is pressed in real time, and the sand-reducing beam turret should be rotated smoothly. Do not operate too hard and produce impact.

4. The user pays attention to whether the mold is good before and after production, and whether the positioning pin of the outer mold and the core mold is matched.

5. Green sand moulding machine operators should concentrate on thinking.

6. After the green sand moulding machine is completed, the mold should be lifted to the specified pouring point (line) according to the process regulations. Place it neatly and lock it with a pressure iron or clip. Miscellaneous pieces indicate the mark.

7. The green sand moulding machine sand box is not allowed to be stacked too high, generally not more than two meters, the tools used must be stacked neatly to prevent accidents.

8. When using the blowtorch, pay attention to safety and prevent fire. Use the low-voltage bulb below 36V and disable the high-voltage bulb above 220V.

9. When using the green sand moulding machine, check whether the spreader is good. When lifting, the hook should be straightened and the chain should be straightened. It is not allowed to slant and overload.

10. It is forbidden to modify the mold under the lifting sand box. When the large sand box is unpacked, it is necessary to use a square object when turning over the cushion box.

11. The sand box used in the green sand moulding machine is firm, and the hand should be completely free of cracks and bending.

When using the green sand moulding machine, the operator should be familiar with the mechanical parts, electrical components, operating procedures, lubrication systems, etc. of the green sand moulding machine, as well as other requirements specified in the use of the equipment. The green sand moulding machine compacts the sand type program in 4 steps. : tamping, indentation, compaction, and pressure head.
