Latest Patents
Yamashita's latest patents include a method of force-fitting a separate member into a casting and a die casting apparatus. The method involves filling a cavity defined by a casting mold with molten metal while a sliding member is positioned within the cavity. Once the molten metal solidifies, the sliding member is drawn out, allowing a separate member to be force-fitted into a concave portion of the casting. This process occurs while the casting remains enclosed in the mold, ensuring a secure fit.
The die casting apparatus he developed aims to produce high-quality cast products with minimal gas defects. It features simplified constructions, such as an electromagnetic induction coil and a movable contractible container. This design allows for localized molten metal injection, effectively inhibiting gas involvement during the casting process.
