Description

Technical Field

[0001] The utility model relates to the technical field of magnetic tile production, in particular to a wet-process magnet forming device with a die-shaped support component. Background Art

[0002] In the production process of wet magnet die-casting, after the amount of material delivered by the feeding system to the die-casting mold reaches the standard, a hydraulic press is needed to cooperate with the die-casting mold to die-cast the material. During the die-casting process, the material in the die-casting mold will discharge the moisture in the material.

[0003] At present, in order to quickly drain water and obtain magnetic tile products with better molding density, a top-type hydraulic press has been designed, such as Figure 1 As shown, the top-pressing hydraulic press is generally equipped with a top-pressing connecting plate on the lower telescopic cylinder, and a guide top-pressing block passing through the pressure-bearing device is set on the top-pressing connecting plate. The guide top-pressing block pushes up the punch during the die-casting action to complete the die-casting of the magnet.

[0004] During the magnet die-casting process, the upper die is first driven downward by the upper telescopic cylinder until the upper and lower dies are in contact. This process is called die closing. The lower die is then driven upward by the lower telescopic cylinder. Once the die reaches the set position, pressure is maintained. During the pressure-maintaining process, the downward pressure of the upper telescopic cylinder gradually increases, causing the pressure-bearing substrate to continuously withstand pressure from the equipment above. As the pressure on the pressure-bearing substrate gradually increases, the risk of bending increases.

[0005] In addition, in the current equipment, since the magnetizing structure is set above the lower mold, and the magnetizing structure is heavy, most of which can reach several tons, when the equipment is closed, the pressure-bearing base plate needs to support the magnetizing structure for a long time, which also invisibly increases the risk of bending of the pressure-bearing base plate.

[0006] In order to solve the problem of high bending risk of the pressure-bearing substrate during the pressure-holding process, the inventor designed a wet magnet forming device with a mouth-shaped support component, and thus proposed the present application. Utility Model Content
