Title: Hitoshi Ishida: Innovator in Casting Technology
Introduction
Hitoshi Ishida is a prominent inventor based in Fuchu, Japan. He has made significant contributions to the field of casting technology, holding a total of 11 patents. His innovative work focuses on improving the efficiency and safety of metal casting processes.
Latest Patents
Among his latest patents are the "Tilting Gravity Casting Apparatus" and the "Tilting Gravity Casting Method." The tilting gravity casting apparatus features a die that includes a ladle for storing molten metal. When the die is tilted, the molten metal is poured through a runner into the die's cavity. This apparatus is equipped with a block member to block the runner, a pressing pin to press the molten metal in the cavity, and a controller that manages the operation of both the block member and the pressing pin. A first molten metal sensing sensor is also installed in the runner, allowing the controller to initiate the operation based on detection signals.
Another notable patent is the "Method for Discharging Gas Out of Metal Molds and Apparatus Therefor." This method and apparatus are designed to continuously discharge contaminated gas from metal molds, which is generated before the casting step and includes moisture. A gas vent valve is integrated into the gas vent passage that communicates with the mold cavity. The system includes a suction unit and a vacuum pump that can be selectively connected to the gas vent valve. After the metal molds are closed, the suction unit is activated to remove contaminated gas, replacing it with clean air. This process helps prevent vapor explosions during injection molding by removing moisture from the mold cavity.
