Patent number: 6638047Abstract: A molding machine comprising an injection portion with an injection nozzle which injects a molding material, a turntable comprising a rotation driving apparatus, a plurality of molds placed along a peripheral edge of the turntable, an attaching and detaching station, an injection station and a plurality of curing stations. Each mold comprises a material receiving port communicating with the injection nozzle when the mold is positioned at the injection station. Each mold further comprises a mechanism which close the material receiving port so as to prevent the molding material from flowing backward when the mold is separated from the injection nozzle. The molds are transferred by rotation of the turntable to each station one by one. Primary formed products are attached to the molds at the attaching and detaching station, injected at the injection station, cured to be second formed products at the curing stations and finally took out at the attaching and detaching station.Type: GrantFiled: September 26, 2001Date of Patent: October 28, 2003Assignee: Yazaki CorporationInventors: Fumio Asai, Norio Kawamura, Yoshiyuki Akiyama, Hiroshi Murashita, Junichi Hamamoto, Toshihiro Kitagawa

Patent number: 6536108Abstract: In a production apparatus (1), after rear holders (7a, 7b) and a housing body (8) are molded by molding die cavities, slides (11a, 11b) are moved apart from the housing body (8). Then, cylinders (16a, 16b) are driven to move the rear holders (7a, 7b), holders (13a, 13b) and the slides (11a, 11b) together with slide plates (14a, 14b), so that the rear holders (7a, 7b) are located in opposed relation to the housing body (8). Then, cylinders (19a, 19b) are driven to move the rear holders (7a, 7b) toward the housing body (8), thereby provisionally retaining the rear holders (7a, 7b) on the housing body (8). Therefore, the amount of movement of the slides (11a, 11b) is small, and it is not necessary to provide any space for holding the slides (11a, 11b), moved into their respective stand-by positions, and therefore the small-size design of the production apparatus can be achieved, and also the production efficiency can be enhanced.Type: GrantFiled: December 19, 2000Date of Patent: March 25, 2003Assignee: Yazaki CorporationInventors: Norio Kawamura, Hiroshi Murashita, Junichi Hamamoto, Takashi Masuda, Toshimi Nakashima, Kazuhiko Hiraguchi, Kenji Takahashi

Patent number: 5709831Abstract: A method of producing a connector with a rear holder, wherein a housing 2 and a rear holder 3 are molded separately from each other by a set of molds 31 to 34. After molding, one of the molds (33) is moved to form a space between the housing 2 and the rear holder 3, and using another (34) of the molds, the rear holder 3 is moved toward the housing 2, thereby provisionally retaining the rear holder 3 on the housing 2.Type: GrantFiled: June 5, 1996Date of Patent: January 20, 1998Assignee: Yazaki CorporationInventors: Takayoshi Endo, Yuji Hatagishi, Nolio Kawamura, Junichi Hamamoto, Motohisa Kashiyama, Yasuhiro Yamaguchi, Toshihiko Yamamoto, Takeyuki Hamaguchi
