Description

Technical Field

[0002] As one of the main means of transportation in today's society, the quality and performance of its parts are directly related to the safety performance of the entire vehicle. As one of the important load-bearing parts of the car, the wheel needs to ensure its high quality and reliability during the manufacturing process.

[0003] Wheels are usually produced using a mold forming process, and mold preparation and maintenance play a vital role in the entire production process. The quality of the mold directly affects the appearance, precision and performance of the wheel. In order to ensure that the mold can accurately replicate the details on the design drawings and avoid any errors in production, the mold is sandblasted before spraying to ensure that the mold surface is clean and has an appropriate roughness to improve the adhesion and effect of the paint. When sandblasting the mold before spraying the paint, sand particles often remain on the mold surface and the matching gap, and sand removal is required.

[0004] Traditionally, sand blasting is done manually using compressed air. It is difficult to completely remove the sand in the gap of the mold by manual sand blasting, which results in the sand in the gap of the mold falling into the mold cavity as the mold opens and closes during the subsequent production process, causing quality problems such as slag inclusion in the spokes of the product and resulting in waste.

However, this application may also be implemented in other ways different from the descriptions herein. Persons skilled in the art may, under the guidance of the concepts of this application, adopt different technical means to implement this application. Therefore, this application is not limited to the specific embodiments below.

[0028] The present application claims protection for a sand removal device which can solve the problem of incomplete sand removal in traditional artificial sand blowing.

[0029] At present, the production of automobile parts such as wheels usually adopts the mold forming process. In order to ensure the cleanliness of the mold surface, manual sand blowing is performed before spraying. However, it is difficult to completely remove the sand particles in the gap of the mold by manual sand blowing. In the subsequent production process, these residual sand particles will enter the mold cavity as the mold opens and closes, causing quality problems such as slag inclusion in the product and generating a large amount of waste.

[0030] Based on this, the present application proposes a mold sand removal device, which utilizes the vibration generated by a vibration motor and a special structural design to effectively remove sand particles from the mold surface and fitting gaps, thereby avoiding the occurrence of quality problems such as slag inclusion in the product during the production process and improving the product yield.

The two cross beams 13 are parallel to connect the first rectangular frame 11 and the second rectangular frame 12 on the same side corners to form a cubic structure.

[0034] The first rectangular frame 11 and the second rectangular frame 12 of the upper support frame 1 are fixed on the second support platform 4 by riveting or welding.

[0035] Reference Figure 2 As shown, the lower support frame 2 is fixed below the upper support frame 1, and includes a third rectangular frame 21 and four support legs 22. The four support legs 22 are fixed at the four corners below the third rectangular frame 21 to support the entire device and ensure its stability.

[0036] The length of the support leg 22 can be adjusted according to actual use requirements to adapt to different working environments.

[0037] Furthermore, a footrest is provided at the bottom of the support leg 22 to increase the contact area with the ground, thereby enhancing the overall stability of the device and reducing the impact of the device on the ground when it vibrates.

[0038] Furthermore, a pulley with a locking function can be provided at the bottom of the support leg 22, which can be unlocked when the device needs to be moved, and locked during operation to prevent the device from sliding. The setting of the pulley facilitates the movement and adjustment of the device, and improves the flexibility of the device.
