Patent number: 12083727Abstract: A technique for providing assistance in setting the time to increase the clamping force is provided. A control device of an injection molding machine includes a clamping control part and a monitoring part. The clamping control part is configured to change, in a filling step of filling the inside of a mold device with a molding material during clamping, a set value of clamping force from a first set value to a second set value that is larger than the first set value, at a predetermined pressurizing timing in the middle of the filling step. The monitoring part is configured to monitor changes in the actual value of the clamping force due to changes in the set value of the clamping force.Type: GrantFiled: November 15, 2022Date of Patent: September 10, 2024Assignee: SUMITOMO HEAVY INDUSTRIES, LTD.Inventors: Yutaka Tsutsumi, Daigo Hotta, Shun Shibuya, Yuki Matsui
