A molding that not only prevents the occurrence of shrinkage cavities but with which it is also possible to obtain rigidity and firm attachment strength even with a limited amount of material and to reduce the cost of the die device and achieve a more compact device using an easily molded shape. The molding (10) has, along the outer circumference of a protruding section (20), column base ribs (30) that extend in the axial direction of the protruding section, said direction intersecting with the back surface of a substrate (11), and that extend out from the base end of the protruding section (20) in the axial direction of the protruding section. The protruding section (20) is bonded via the column base ribs (30) to the back surface of the substrate (11) so that the base end is supported at a distance from the back surface. The column base ribs (30) have a shape that can be mold-released by cores (44), which release outward. The cores are separated, when the protruding section (20) is the center, from each other along the escaping direction, which intersects with the mold-release direction of the molding (10) as a whole, said mold-release direction being parallel to the axial direction of the boss.
The invention is an undercut processing mechanism that is able to perform de-molding easily even when the undercut portion (P1) of a molding (P) has a shape that is irregular on both sides of the direction orthogonal to the direction of de-molding by implementing a larger movement stroke within a limited set-up space. Inside a holder (30) that is disposed inside a movable mold (13), a pair of molding cores (51, 52) that mold the undercut portion (P1) are connected to and supported by a holding piece (40) that moves in the de-molding direction. During de-molding, the respective molding cores (51, 52) are guided by guiding means (33, 34) from a molding position in which the cores contact each other towards a mold release position in which the cores are separated, and each moves in front or in back so as to move past each other in opposite directions from one end of the holding piece (40) to the other end.

An undercut processing mechanism can facilitate punching-out of undercut portions having various shapes spreading in the circumferential direction on the inside of a molded article. Split cores (61) that form an undercut molding core (60) are supported one by one at the leading end of slide members (50) disposed radially to face the center axis of an undercut portion (P3). Each slide member (50) is housed in a holder (40) so as to be slidable between a molding position where the split cores (61) are mutually disposed in the entire circumferential direction and a demolding position where the split cores (61) are mutually reduced in diameter. The holder (40) is provided with a guide member (46) for guiding each slide member (50) to move simultaneously in the punching-out direction parallel to the center axis of the undercut portion (P3) and in the direction escaping from the undercut portion (P3) toward the center axis of the undercut portion (P3), respectively, along an inclination direction from the molding position toward the demolding position.
An undercut processing mechanism for facilitating the releasing of a molded article from a mold having various shapes where the relief direction at an undercut portion is different on the lower surface side and on the upper surface side. Split cores (61, 62) stacked vertically to form an undercut molding core (60) are supported by slide members (51, 52) arranged in parallel in the front and back direction. The slide members (51, 52) are contained in a holder (40) built in a movable die (14) such that the split cores (61, 62) being supported move in the same releasing direction and in separate relief directions intersecting at a different angle in the relasing direction. The holder (40) is provided with inclining grooves (43, 44) as means for guiding the slide members (51, 52) from the molding position toward the mold releasing position in the inclining direction.
