Patent number: 7588713Abstract: Resin boots for constant velocity universal joint in which a different thickness portion is integrally formed in an inner diameter of a large diameter side end portion of a primarily molded resin bellows in accordance with a secondary molding. A resin bellows constituted by a bellows portion, and a small diameter side end portion and a large diameter side end portion which are provided in both end sides of the bellows portion is molded in accordance with a primary molding, and a different thickness portion corresponding to a secondarily molded product is integrally formed in an inner periphery of the large diameter aide end portion of the primarily molded resin bellows by being secondarily molded within an injection metal mold. At this time, a molten material of the different thickness portion is injected into a secondary molding space from an optional position of a thin portion.Type: GrantFiled: March 26, 2003Date of Patent: September 15, 2009Assignee: Fukoku Co., Ltd.Inventors: Kazuhiko Sueoka, Yasuji Takada

Publication number: 20090224429Abstract: Since all points on a spherical surface are equidistant from the center of its sphere, the occurrence of interference during mold release can be prevented by releasing the half sphere along the normal direction of a plane passing through the center of the sphere. In this invention, the upper and lower molds of the ball chain each has a protruding configuration having a spherical surface, and the upper and lower molds are released along an inclined direction, thus preventing the interference between the protruding configuration and the finished product during mold release. Such mold releasing method also can solve the difficulties in production and can improve the effect of the spacers for separating the steel balls.Type: ApplicationFiled: May 15, 2009Publication date: September 10, 2009Inventor: Chang-Hsin KUO
