Abstract

This project presents the design and analysis of casting mold using CAD Tool. The project basically investigated the design parameters for the casting mold and simulated the temperature and pressure on the mold. Turbocharger impeller was selected as the product of the study. Among the various types of casting techniques, investment casting process is the most suitable process to produce the turbocharger impeller. The alternative design of casting mold by investment casting was generated using CAD software. Concept scoring was prepared in order to select the suitable design for the investment casting process. Material selection of turbocharger is Aluminum Silicon Carbide. Stainless steel AISI H13 is selected as the material for the mold. The parameter for the mold design is included branch, gating, sprue and runner. Analysis was presented to the mold by using ANSYS simulation tool, in order to determine the temperature and pressure of the mold. In addition, three case studies were presented in order to compare the static pressure in different velocity and temperature of the mold design. The result showed the runner and the branch size were important to produce the molten metal flow into the mold pattern. As a result, the design of investment casting mold was proposed.
