Description

Profiling spraying box for micro-spraying of structural parts

Technical Field

The utility model belongs to the technical field of die manufacturing, and particularly relates to a profiling spraying box for micro-spraying of structural parts.

Background

With the development of the automobile industry towards light weight and the progress of the integrated die casting technology, the production of automobile structural parts is gradually changed from the traditional stamping process to the die casting process. This transition brings about a higher requirement for the precision and efficiency of the die casting process. Particularly in the trend of integrating multiple parts into one die casting, the rapid increase in the number of products presents a higher challenge to the die casting process.

In the production of automotive structural parts, these parts are mainly used for fixing and reducing vibrations. Traditionally, most automotive structural members are formed from sheet metal stamping. However, with the advancement of weight reduction, press molding by die casting an aluminum alloy structural member instead of sheet metal has become a trend. This transition results in uneven wall thickness of the product and, when using conventional spray boxes, large local temperature differences in the mould, thus leading to deformation of the structural part.

Conventional die-cast spray cartridges are generally rectangular in shape, with spray nozzles and blow-up nozzles on both sides. After the die casting machine is opened, the spraying box enters the middle of the die, and the mold release agent spraying is carried out on the moving and fixed die of the die through repeated movement and rotation angles. After the spraying is finished, the compressed air sweeps the surface of the die through a nozzle to remove residual moisture. However, in the production process, the use of the conventional spray coating cartridge requires repeated movement of the position and rotation angle due to the large height drop (maximum height difference up to 520 mm) of the product, resulting in low production efficiency.

In addition, because the wall thickness of the structural part has difference, when the conventional spraying box is adopted for production, the temperature of the central part of the die is higher, the temperature of other parts is relatively lower, the die temperature is unbalanced, and the product is easy to deform. In the spraying process, part of the area forms a spraying dead angle, so that the demolding dosage is insufficient, and the defects of aluminum sticking, pull injury and the like are easily formed when the product is ejected. Therefore, the conventional spray coating cartridge requires repetitive movement when spraying the release agent, further reducing the production efficiency.
