Title: Seiichi Kurosawa: Innovator in Injection Molding Technology
Introduction
Seiichi Kurosawa is a notable inventor based in Yokkaichi, Japan. He has made significant contributions to the field of injection molding technology. With a total of 3 patents, his work has advanced manufacturing processes in various applications.
Latest Patents
Kurosawa's latest patents include innovative designs and methods that enhance the efficiency of injection molding. One of his patents is for a mold for injection molding and a method of operating a mold. This invention features a fixed mold with engaging pins that project towards a movable mold. Each engaging pin includes a shaft and a large-diameter portion formed at the leading end of the shaft. The large-diameter portions of the engaging pins interfere with the bottom surfaces of recesses in an ejector plate during the separation process of the movable mold. This design allows the ejector plate to move forward relative to the movable mold, enabling the leading ends of ejector pins to project from the movable mold.
Another significant patent is for a manufacturing method of a resin molded assembly. This method utilizes a moving mold consisting of slidable housing molds and retainer molds, paired with a fixed mold. The process allows for simultaneous molding of a housing and retainers in resin. When the molds are opened, a space is formed between the housing and the retainers, facilitating their assembly. The retainers are pressed against the housing while being held in the retainer molds, ensuring a precise fit.
