Evaluation of Cooling Performance of an Additive Manufactured Gravity Die Casting Mold with Conformal Cooling Channel

A cooling channel with an optimized design provides not only high throughput gravity die casting, but also guarantees product quality. conformal (CC) whose structure follows the shapes or surfaces of mold cavity has attracted great attention in casting industry, because it allows rapid and uniform cooling. However, implementing remains highly challenging, complicated geometries CC are difficult to form using conventional fabrication methods such as drilling milling. In recent years, advances additive manufacturing (AM) technology have made possible fabricate products complex elaborate structures. this paper, a was designed built AM technology. The performance estimated evaluated Al-Si-Cu alloy simulation experiments, respectively. results showed that enhanced by ca. 10% compared channel. experimental improved 8% channel, increment consistent results. addition, microstructural evidence clarified effective could be attributed decrement (ca. 17%) secondary dendrite arm spacing (SDAS) alloy. research, novel way functionally superior molds hardly producible traditional methods.
