What maintenance is required for gravity casting molds

Gravity casting molds are an important tool for gravity casting process. Gravity casting is a casting process that uses molten metal to fill the cavity and solidify under the action of gravity. In the gravity casting process, the molten metal is first poured into the gate, and the molten metal flows into the cavity under the action of gravity. However, the maintenance and care of the Gravity Casting Machine is essential to ensure the normal operation of the equipment, extend the service life, and ensure the quality of the castings.

 

As the molten metal continues to flow in, the gas in the cavity is discharged through the riser. When the molten metal fills the cavity, it cools and solidifies for a period of time, and the casting is formed. Finally, the casting is ejected from the mold by the ejection mechanism to complete a casting cycle.

 

1. Daily maintenance

 

Cleaning work

After each use, clean the surface and surrounding environment of the gravity Casting Machine in time to remove dust, metal chips and other debris. You can use a clean rag or compressed air to clean it to ensure the appearance of the equipment is neat.

For the mold part, carefully clean the residual molten metal and dirt on the surface of the mold to prevent it from affecting the quality of the next casting. You can use special mold cleaning agents and tools, and be careful not to damage the mold surface.

 

Check the lubrication system

Regularly check the lubrication system of the gravity casting machine to ensure that each lubrication point is fully lubricated. Check whether the oil level of the lubricating oil is normal. If the oil level is found to be too low, add lubricating oil in time.

At the same time, observe the color and texture of the lubricating oil. If the lubricating oil is found to be deteriorated or contaminated, it should be replaced in time. The lubrication requirements of different parts may be different. Choose the appropriate lubricating oil according to the requirements of the equipment manual.

 

Check the fastening parts

Before starting the machine every day, check the fastening parts of the gravity casting machine, such as bolts, nuts, pins, etc., to ensure that they are in a tight state. If loose parts are found, they should be tightened in time to prevent the equipment from loosening or vibrating during operation, affecting the quality of castings and the stability of the equipment.

 

For some key fastening parts, you can use a torque wrench to tighten them according to the specified torque to ensure that the tightening force is moderate.

 

2. Regular maintenance

 

Mold maintenance

Regularly conduct a comprehensive inspection and maintenance of the mold. Check whether the surface of the mold is worn, cracked or deformed. If there is any problem, the mold should be repaired or replaced in time.

Perform regular maintenance on the mold, such as applying rust inhibitors and surface treatment, to extend the service life of the mold. When storing the mold, be careful to avoid collision and extrusion to keep the mold in good condition.

 

Electrical system inspection

Regularly check the electrical system of the gravity casting machine, including the control panel, motor, sensor, etc. Check whether the electrical circuit is loose, damaged or aged. If there is any problem, it should be repaired or replaced in time.

 

Clean the surface of the electrical equipment to remove dust and dirt to prevent it from affecting the heat dissipation and normal operation of the electrical equipment. At the same time, check whether the grounding of the electrical equipment is good to ensure the safe operation of the equipment.

 

Hydraulic system maintenance

Check the hydraulic system of the gravity casting machine, including hydraulic pumps, hydraulic cylinders, hydraulic valves, etc. Check the oil level, color and texture of the hydraulic oil. If the hydraulic oil is found to be deteriorated or contaminated, it should be replaced in time.

 

Clean the filter of the hydraulic system regularly to prevent impurities from entering the hydraulic system and affecting the normal operation of the equipment. At the same time, check whether the seals of the hydraulic system are intact. If there is a leak, the seals should be replaced in time.

 

Adjustment of mechanical parts

Regularly adjust the mechanical parts of the gravity casting machine, such as the clamping mechanism, tilting mechanism, etc. Check whether the movement of each component is flexible. If there is a jam or abnormality, it should be adjusted and repaired in time.

Some mechanical parts with severe wear, such as guide rails, sliders, etc., should be replaced in time to ensure the accuracy and stability of the equipment.

 

3, precautions

 

Safe operation

When maintaining and servicing the gravity casting machine, strictly abide by the safety operating procedures to ensure the safety of the operator. When repairing and adjusting the equipment, the power supply should be cut off first, and warning signs should be hung to prevent others from operating it by mistake.

 

For some high-temperature parts, such as furnaces and molds, pay attention to prevent burns. During operation, wear necessary protective equipment, such as gloves, goggles, etc.

Professional maintenance

 

The maintenance and servicing of the gravity casting machine requires certain professional knowledge and skills. For some complex faults and problems, professional technicians should be asked to repair them in time. Do not disassemble and repair the equipment by yourself to avoid causing greater damage.

Record and file management

 

Establish a maintenance and servicing record file for the gravity casting machine, and record the time, content and results of each maintenance and servicing. This makes it easy to understand the maintenance status of the equipment, find problems in time and take corresponding measures.

 

At the same time, keep the equipment's instructions, maintenance manuals and other technical information for reference when needed.

 

In short, the maintenance and care of gravity casting machines requires daily careful care and regular professional inspections. Only by doing a good job of maintenance and care can the normal operation of the equipment be ensured, the quality of castings can be improved, and the service life of the equipment can be extended.
