Title: Innovations by Atsushi Ishikawa
Introduction
Atsushi Ishikawa is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of injection molding technology. With a total of 5 patents to his name, Ishikawa has developed innovative solutions that enhance the efficiency and accuracy of molding processes.
Latest Patents
One of his latest patents is a mold clamping control device capable of accurately controlling mold clamping forces exerted on a mold during injection molding. This device utilizes a linear encoder to detect the relative position between the movable platen and a fixed platen. Additionally, a strain sensor measures the mold clamping force. The mold clamping control unit is designed with a target platen position value and a target mold clamping force value. It calculates deviations by subtracting the actual values from the target values. The control unit then switches the target to be controlled between the platen position and the mold clamping force, converting the deviation into a control command for a motor. This command is supplied to a motor control unit, which drives the mold clamping motor accordingly.
Another significant patent is a gate cut apparatus and method for a disc molding apparatus. In this invention, a movable mold is positioned to face a stationary mold and can be advanced or retracted. The movable mold creates a cavity in conjunction with the stationary mold during mold clamping. A sprue is aligned with the cavity and features a concave portion at its front end. A cut punch is designed to reciprocate in front of the cavity, entering the concave portion when advanced. The drive section is responsible for advancing and retracting the cut punch, while the controller ensures that the cut punch is advanced with a predetermined extension force during mold clamping, without exceeding a preset value before the mold opens.
