  • Roll molding device
    Patent number: 9724855
    Abstract: In the present invention, when synchronization is lost due to backlash, and deviation between the rotational phases of a first processing roll and a second processing roll occurs, deviation between the rotational phases of dummy rotating bodies also occurs, and dummy blade parts of the dummy rotating bodies interfere with each other before blade parts of cutting blades of the first processing roll and the second processing roll (40) interfere with each other. Thus, interference between the blade parts is prevented.

  • Molding die
    Patent number: 9352494
    Abstract: Provided is a molding die including a die body for molding a molded article, which has an undercut, and a demolding core movable to approach and separate from the die body. When the demolding core is separated from the die body, the demolding core elastically deforms the molded article such that the undercut separates from the die body and makes it possible to remove the molded article from the die body. The die body includes a recess where the depth gradually reduces along the direction in which the demolding core separates from the die body. During molding of the molded article, a projection is formed on the undercut in accordance with the shape of the recess. During removal of the molded article, the engagement between the projection and the recess regulates the movement of the molded article in a direction intersecting the movement direction of the demolding core.
