    • PROBLEM TO BE SOLVED: To provide an injection-molding die which is less costly by ensuring the simultaneous rotary actuation of a die component relative to an undercut part and release of a molded product only by the opening/clamping action of the die.
      SOLUTION: This die is used for injection-molding a plastic product with an undercut part and comprises a cavity-side part plate which serves as a top force with a cavity for molding the external shape of the plastic product and receives a molten resin injected into the cavity for molding, a movable part plate, with an ejection core, which comes into contact, face to face, with the cavity-side part plate, a rotary core which is supported in a rotating fashion by the base of the die and fitted into and retained by the ejection core and has a screw part for molding the undercut part of the plastic product, a separation-actuating mechanism for separating the rotary core from the ejection core of the movable part plate and a rotation-actuating mechanism for rotating the rotary core by the actuation of separating the movable part plate from the cavity-side part plate by means of the separation actuating mechanism.

    • PROBLEM TO BE SOLVED: To provide a device and a method for fastening two components by one operation without installing a special mechanism. SOLUTION: This device comprises one component 10 having at least two parts of a raised shape in cross section with a prescribed lead angle and the other component 20 holding a prescribed position relation to the one component 10, having at least two parts 12 and 16 of a raised shape in cross section engaged with the parts of the raised shape in cross section of the one component 10, and having a lead angle different from the lead angle of the parts of the raised shape in cross section of the one component among the parts 12 and 16 of the raised shape in cross section. These both components 10 and 20 are movable close to each other in an opposed state, the parts of the raised shape in cross section are engaged with each other after moving a specified distance in an opposed state, and these both components are fixedly formed integrally with each other by the frictional engagement of the parts of the raised shape in cross section with different lead angles.
