Patent number: 10828694Abstract: A casting device in which refrigerant is pressure-fed to a cooling passage formed in a die, leakage of refrigerant in the die can be reliably detected in a short time without a significant modification applied to the conventional device. A casting device includes a pressure-feed device that pressure-feeds refrigerant to a cooling passage formed in a die, and a release agent coating applicator that applies a release agent to the die, and further includes a unit that mixes a fluorescent agent into the refrigerant (fluorescent agent tank), a unit that irradiates the die surface of the die with black light while the refrigerant containing the fluorescent agent mixed therein is pressure-fed to the die, and an imaging device that captures an image of the die surface. The imaging device is integrally assembled with the release agent coating applicator.Type: GrantFiled: November 18, 2016Date of Patent: November 10, 2020Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, MEC INTERNATIONAL CO., LTD., MEIWA E-TEC CO., LTD., NIKON CORPORATIONInventors: Daisuke Serino, Fumio Kawahara, Yuzo Matsuda, Tetsushi Yamaguchi, Hiroshi Kawahara, Sakayuki Ishikawa, Takuto Takahashi, Naoshi Sakaguchi, Hiroyuki Kayaba, Takahiro Michimoto

Patent number: 8340468Abstract: Feature points (41, 42, 43) in the heat image (10) of a casting die (1) are extracted and a predetermined geometrical conversion processing is performed on the heat image (10) such that the feature points are superimposed on the reference feature points (61, 62, 63) set in a reference heat image (30) picked up previously to generate a corrected heat image (20). A difference image (40) is generated by superimposing the corrected heat image (20) and the reference heat image (30) such that the corrected feature points (51, 52, 53) in the corrected heat image (20) is superimposed on the corresponding reference feature points (61, 62, 63). With such an arrangement, a highly reliable difference image can be generated even when the imaging field of vision slips off among a plurality of heat images.Type: GrantFiled: March 25, 2008Date of Patent: December 25, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, MEIWA e-TEC co., ltd.Inventors: Yuichi Furukawa, Shingo Nakamura, Yuji Okada, Fumio Kawahara
