Automobile inspection rack aluminum extrusion dies

The working principle of extruded aluminum profile mold mainly includes the following steps:

1. Preheating

2. Extrusion

3. Cooling

4. Cutting

5. Heat treatment

6. Surface treatment

In the whole process, the function of the extrusion die is to determine the shape of the extruded aluminum profile through the shape of its internal cavity during the extrusion process. The design and production of molds directly affect the quality and production efficiency of aluminum profiles.

The Main Advantages of Hollow Mold

1.It can extrude hollow profiles or pipes with double-hole or multi-hole inner chambers, and can also produce multiple hollow products at the same time, so the production efficiency is high, which is difficult or even impossible to achieve with bridge tongue molds;

2.It can extrude semi-hollow profiles with large cantilever beams that are difficult to produce with plane dies;

3.Removable, easy to process, low cost;

4.Easy to separate residual materials, simple operation, short auxiliary time, the extrusion cycle can be completed with ordinary tools on ordinary bar extruders, and at the same time, the residual materials are short and the yield is high;

5.Continuous extrusion can be realized, and products of any length can be cut according to needs;

6.The number, size and shape of the split holes can be changed, so that the cross-sectional shape is relatively complex, the wall thickness difference is large, and it is difficult to use the working belt, the obstruction corner, etc. to adjust the flow rate of the hollow profile well;

7.A taper split hole can be used to extrude a hollow product with a larger shape on a small extruder, and it can ensure sufficient deformation.

Precautions when using extruded aluminum molds:

1.Mold installation: When installing the mold, it is necessary to ensure that the mold is installed in the correct position and fixed stably to avoid the mold from shifting or falling off during the production process.

2. Temperature control: The mold will generate a lot of heat during use, and the temperature of the mold needs to be effectively controlled to prevent the mold from overheating and causing deformation or damage.

3. Cleaning and maintenance: During the use of the mold, regular cleaning and maintenance are required to ensure the service life of the mold. When cleaning, avoid scratching with hard objects to prevent damage to the mold surface.

4. Avoid overuse: During the use of the mold, excessive use should be avoided to prevent premature wear of the mold. Generally speaking, molds need to be replaced after being used for a period of time to ensure product quality.

5. Use appropriate lubricants: During the use of the mold, appropriate lubricants should be used to reduce mold wear and improve production efficiency.

6. Regular inspection: During the use of the mold, the mold needs to be inspected regularly to find out whether there are cracks, deformations and other problems in the mold so that they can be dealt with in a timely manner.

7. Use special tools: When disassembling and installing the mold, special tools should be used to avoid mold damage caused by using inappropriate tools.

8. Train operators: Operators need to receive professional training to understand the usage and precautions of the mold to avoid mold damage due to improper operation.
