Title: Shigetake Kami: Innovator in Die-Casting Technology
Introduction
Shigetake Kami is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of die-casting technology, holding a total of 4 patents. His innovative methods and devices have improved the efficiency and reliability of die-casting processes.
Latest Patents
One of Kami's latest patents is a method for cooling the plunger tip of a die-casting machine. This method ensures that a proper clearance is maintained between the plunger tip and the shot sleeve. It involves determining the appropriate hydraulic pressure in the injection cylinder to prevent galling in the shot sleeve. The hydraulic pressure is measured multiple times when no molten metal is present in the shot sleeve. The average hydraulic pressure is then compared to the proper hydraulic pressure, allowing for adjustments to the cooling liquid supply to the plunger tip.
Another notable patent is a device and method for detecting abnormalities in die casting during the ejection process. This device includes a setting mechanism for storing predetermined values, such as the upper limit of acceleration of the ejector plate. An accelerometer measures the acceleration during the ejection process, and a computing device compares this measurement to the set values. If the acceleration exceeds the upper limit, a warning signal is generated, enabling timely detection of galling.
