Description

Technical Field

[0001] The present application relates to the technical field of die-casting molds, and in particular to a mold with a heat-sink air-cooling and heat dissipation structure. Background Art

[0002] A die casting mold is a mold used in the die casting process, which is a metal casting process that injects molten metal into the mold cavity under high pressure, allowing it to quickly cool and solidify into a casting. Die casting molds usually need to withstand high pressure and temperature, so they are usually made of high-strength steel and designed to withstand the thermal stress caused by high-pressure injection and rapid cooling. Die casting molds are characterized by high production efficiency, good casting surface quality, high dimensional accuracy, and are suitable for the production of small or medium-sized castings with complex shapes.

[0003] In the related art, the die casting mold generally includes a fixed mold and a movable mold. When the fixed mold and the movable mold are closed, a complete molding cavity is formed, and then the molten metal is pushed into the molding cavity. After cooling, the molten metal solidifies and forms. In order to speed up the molding speed, a cooling device, such as a water cooling device or an air cooling device, is generally installed on the die casting mold. The cooling device is used to cool the die casting mold, thereby improving the processing efficiency.

[0004] During the casting process, hot spots are easily formed at nodes or local areas where the metal solidifies slowly inside the casting, causing shrinkage in the hot spot area of ​​the casting, affecting product quality. When the cooling device in the related art cools the molding cavity, it is difficult to perform targeted cooling on the hot spot area, which easily causes uneven cooling in different areas of the molding cavity, affecting the processing quality of the final product.
