[0003] The shape of die-casting products is usually relatively complex, so there will be suspended parts of the product or parts extending outward from the main body of the product. The connection between these suspended parts of the product and the main body of the product is usually relatively weak. The suspended parts of the product have a certain deformation space. During transportation and loading and unloading, the suspended parts of the product will deform. When processing the parts of the product that may deform, according to Chinese Patent CN219617710U, a fixture for die-casting part processing is disclosed. This fixture uses six clamping blocks to adapt to the end face of the die-casting part to achieve the purpose of fixation. However, when the die-casting part has a deformable space, forced pressing and positioning will cause stress on the suspended part of the product, and when processing this part, it will affect its processing accuracy.
