Tooling for use in forming a variable taper component is provided. The tooling includes an inner mandrel and an outer mandrel disposed around the inner mandrel. The inner mandrel includes a master insert defining opposed tapered edge faces, an external surface having a variable taper and a plurality of recesses configured to receive at least a portion of the variable taper component, and a tapered internal surface. The inner mandrel also includes a plurality of interlocking pieces arranged concentrically around the master insert, and a tapered inner sleeve disposed against the tapered internal surfaces of the plurality of interlocking pieces and the master insert. The outer mandrel defines a corresponding plurality of recesses configured to receive at least a portion of the variable taper component, wherein a maximum width of the interlocking pieces and the master insert is smaller than a minimum width of ends of the variable taper component.

A rotary core includes an undercut portion molding section for molding an undercut portion in a resin-molded article, and a seal portion abutting on a mold main body. In a side view viewed from a direction orthogonal to the direction in which a shaft member serving as the rotation center of the rotary core extends, a first imaginary line extending along the inner edge of the seal portion, and a second imaginary line extending from the rotation center to the first imaginary line and orthogonal to the first imaginary line are drawn. The seal portion includes a portion that is located on a lower side of the second imaginary line and is bent inward in the width direction as compared with a portion of the seal portion that is located on an upper side of the second imaginary line.

This mold device has a rotary core that rotates about a shaft member as a rotation center by being provided with a rotational driving force directly from a rotation driving means. A restriction core is interposed between the rotary core and a mold body to restrict the rotation of the rotary core. That is, the rotary core becomes rotatable when the restriction core is withdrawn from between the rotary core and the mold body.

A core lifter having lifter bar with an elongate blade which carries a coupling head received in an elongate lifter bar coupling receiver formed in the base configured to permit pivotable, swiveling and/or translational misalignment or tolerance compensation during core lifter assembly, installation, and operation in a plastic formable material molding apparatus, including during mold cycling advantageously preventing core lifter binding and extending core lifter life. A preferred lifter has a lifter bar formed of a blade to which a lifter bar coupling ball is attached that is received in an elongate longitudinally extending channel having a transverse cross section complementary to the ball defining a bearing race in which the ball is received enabling slidable pivoting, swiveling and slidable movement of the ball and blade relative thereto including while the ball and blade are slidably moving along the race in a longitudinal or lengthwise direction relative to the base.

Provided are a device and method for molding an FPC and a plastic part, which belongs to the field of FPC processing technology. The method for molding an FPC and a plastic part includes preprocessing a preform and connecting an FPC to the outer cylindrical surface of the preform; and forming a coating on the outer cylindrical surface of the preform by using the device for molding an FPC and a plastic part.
