Abstract

<p>For the realization of "Celebrate Driving", Mazda's brand essence, importance of improving accuracy and saving weight in casting parts is increasing corresponding to higher functionalization of cars. One of those parts, a cylinder block, composes a part of the engine and is manufactured in aluminum die-cast process for saving weight. It has one or two holes called "main oil gallery" to distribute lubricating oil are molded by the core pin. We had an issue that the holes were often bended in die-cast process, therefore the bent area was cut by machining. We elucidated the mechanism of bending, modeled it, and established a mold technology to prevent the core pin from bending. This technology enables us to manufacture the part without cutting by machining. This paper reports our activities.</p>
